"Anything above marijuana takes priority": Obstetric providers' attitudes and counseling strategies regarding perinatal marijuana use

Perspectives of adolescents and young adults on cannabis use during pregnancy

PURPOSE

Rates of cannabis use during pregnancy are highest for adolescents and young adults (AYAs). This study aims to understand AYA perspectives regarding the medical and legal consequences of prenatal and parental cannabis use.

METHODS

This study delivered five open-ended survey questions regarding prenatal cannabis use in May/June 2022 via a text message polling platform to the MyVoice cohort, a cohort of AYA aged 14-24 throughout the United States recruited from social media to target national benchmarks set by the American Community Survey. We used qualitative content analysis to analyze open-ended responses and summarized code frequency and demographic data with descriptive statistics.

RESULTS

Of 826 AYAs, 666 responded to at least one question (response rate = 80.6 %) and the mean age of respondents was 19.9 years (SD = 2.3). We identified four themes from responses: (1) AYA believe cannabis is harmful during pregnancy, (2) they are divided on whether prenatal cannabis exposure should be considered child abuse or neglect, (3) they have mixed attitudes about safe parenting and regular cannabis use, and (4) they support counseling from health care professionals about prenatal cannabis use.

CONCLUSIONS

AYAs were concerned about potential risks of prenatal cannabis exposure and want clinicians to counsel about cannabis use during pregnancy. More than one in three AYAs surveyed felt prenatal cannabis use should be classified as child abuse or neglect, in contrast to the declining perception of risk among pregnant people.

Interpersonal Influences on the Choice to Treat Nausea during Pregnancy with Medication or Cannabis

OBJECTIVE

 This study aimed to better understand the interpersonal influences on a pregnant individual's decision of how to treat nausea and vomiting during pregnancy using a qualitative approach.

STUDY DESIGN

 A semistructured interview guide was developed to assess pregnancy symptoms, decision-making regarding treating nausea, and interpersonal influences on treatment decisions. Interviews were conducted with 17 individuals enrolled in a neuroimaging and behavioral study of prenatal exposure to cannabis who used medication and/or cannabis to treat symptoms associated with pregnancy.

RESULTS

 Interviews revealed four groups of stakeholders who influenced participant decision-making: medical providers, partners, family, and friends. Influence was categorized as either positive, negative, neutral, or absent (if not discussed or participant chose not to disclose). Those in the medication group reported only positive or neutral feedback from friends, family, partners, and providers. In contrast, the cannabis group participants reported positive feedback from friends, mixed feedback from family and partners, and negative feedback from providers, which was often felt to be stigmatizing. Many in the cannabis group also reported varying feedback from different medical providers. While the cannabis group frequently reported eliciting feedback from friends, family, and partners, the medication group often did not.

CONCLUSION

 Medication group participants reported entirely positive feedback from providers and often did not mention any feedback at all from partners, family, and friends. Cannabis group participants reported much more varied feedback, both positive and negative, from a variety of interpersonal contacts and sometimes decided to conceal their treatment choice after receiving or fearing negative feedback. We recommend further research into the health outcomes of pregnant patients who chose not to discuss their treatment decisions with providers, family, partners, or friends. We also suggest further study of possible reasons behind a lack of disclosure, including fear of stigma and/or legal consequences.

KEY POINTS

· Providers, partners, family, friends gave feedback.. · Medication group got positive feedback.. · Cannabis group stigmatized by providers.. · Cannabis group got mixed feedback..

Development and validation of the Cannabis Exposure in Pregnancy Tool (CEPT): a mixed methods study

BACKGROUND

Evidence of associations between prenatal cannabis use (PCU) and maternal and infant health outcomes remains conflicting amid broad legalization of cannabis across Canada and 40 American states. A critical limitation of existing evidence lies in the non-standardized and crude measurement of prenatal cannabis use (PCU), resulting in high risk of misclassification bias. We developed a standardized tool to comprehensively measure prenatal cannabis use in pregnant populations for research purposes.

METHODS

We conducted a mixed-methods, patient-oriented tool development and validation study, using a bias-minimizing process. Following an environmental scan and critical appraisal of existing prenatal substance use tools, we recruited pregnant participants via targeted social media advertising and obstetric clinics in Alberta, Canada. We conducted individual in-depth interviews and cognitive interviewing in separate sub-samples, to develop and refine our tool. We assessed convergent and discriminant validity internal consistency and 3-month test-retest reliability, and validated the tool externally against urine-THC bioassays.

RESULTS

Two hundred fifty four pregnant women participated. The 9-item Cannabis Exposure in Pregnancy Tool (CEPT) had excellent discriminant (Cohen's kappa = -0.27-0.15) and convergent (Cohen's kappa = 0.72-1.0) validity; as well as high internal consistency (Chronbach's alpha = 0.92), and very good test-retest reliability (weighted Kappa = 0.92, 95% C.I. [0.86-0.97]). The CEPT is valid against urine THC bioassay (sensitivity = 100%, specificity = 82%).

CONCLUSION

The CEPT is a novel, valid and reliable measure of frequency, timing, dose, and mode of PCU, in a contemporary sample of pregnant women. Using CEPT (compared to non-standardized tools) can improve measurement accuracy, and thus the quality of research examining PCU and maternal and child health outcomes.

Perceptions and Prevalence of Cannabis Use in Women With Inflammatory Bowel Disease of Reproductive Age: A Cross-Sectional Study

Background

Many patients with inflammatory bowel disease (IBD) may use cannabis for relief of symptoms. During pregnancy, however, cannabis exposure may be associated with adverse pregnancy outcomes. We aimed to determine the prevalence and perceptions of cannabis use in women with IBD.

Methods

Through recruitment at Mount Sinai Hospital and online platforms such as Twitter, women with IBD (age 18-45) were asked to complete anonymous surveys on demographics, cannabis use, perception of use during pregnancy, and discussing its use with healthcare providers (HCP). Categorical variables were reported as frequencies and compared across groups with the chi-square test.

Results

One-hundred and two pregnant patients with IBD were included in this study, 19 (18.6%) reported using cannabis. Current users were more likely to report constant pain in the last 12 months and discuss its use with their HCP. Fifty-three (52.0%) women were unsure of the specific risks associated with cannabis use during pregnancy, and only 15 (14.7%) had ever discussed its use with their HCP. Those who had discussed cannabis use with their HCP were more likely to have prior IBD-related surgery, perceive its use unsafe during pregnancy, and be more likely to be using cannabis.

Conclusion

Many women with IBD report uncertainty of the risks of cannabis use during pregnancy and the majority have never discussed cannabis use with their providers. With the increasing legalization of cannabis in many jurisdictions, it is imperative patients and healthcare providers discuss the risks and benefits of its use, particularly during vulnerable times such as pregnancy.

Alcohol and cannabis use among women with infertility: associations with psychiatric symptoms, attempts to conceive, and engagement in fertility treatment

Little is known about substance use among women with infertility, yet substance use has implications for fertility and pregnancy. The purpose was to estimate the prevalence of substance use among women with infertility and examine whether substance use was associated with psychiatric symptoms, active attempts to conceive, and engagement in fertility treatments. Eligible patients were from a single healthcare system who received a female infertility diagnosis within the past 2 years. Participants (n = 188) completed an online questionnaire regarding substance use, psychiatric symptoms, attempts to conceive, and fertility treatments. The prevalence of hazardous alcohol use, any cannabis use, and hazardous cannabis use were 30.3%, 30.9%, and 8.5%, respectively. Hazardous alcohol use was not associated with psychiatric symptoms (p > .05). Those with any cannabis use were more likely to have higher depression scores than those without (p = .02). Those with hazardous cannabis use were more likely to have higher depression scores (p = .001) and higher anxiety scores (p = .03). Substance use was not associated with actively trying to conceive. Those pursuing fertility treatments had a lower percentage engaging in hazardous alcohol use compared to those not pursuing fertility treatments (19.0% vs. 36.3%, p = .02). Substance use among women with infertility is common. Hazardous cannabis use was associated with greater psychiatric symptoms, suggesting that cannabis may be used to cope with distress. Pursuing fertility treatments may serve as a protective factor for hazardous alcohol use. Clinicians treating patients with infertility may want to screen for substance use.

The impact of pregnancy and associated hormones on the pharmacokinetics of Δ9-tetrahydrocannabinol

INTRODUCTION

(-)-Δ9-tetrahydrocannabinol (THC) is the main psychoactive component of cannabis. Cannabis is the most widely used drug of abuse by pregnant individuals, but its maternal-fetal safety is still unclear. The changes in THC disposition during pregnancy may affect THC safety and pharmacology.

AREAS COVERED

This review summarizes the current literature on THC metabolism and pharmacokinetics in humans. It provides an analysis of how hormonal changes during pregnancy may alter the expression of cannabinoid metabolizing enzymes and THC and its metabolite pharmacokinetics. THC is predominately (>70%) cleared by hepatic metabolism to its psychoactive active metabolite, 11-OH-THC by cytochrome P450 (CYP) 2C9 and to other metabolites (<30%) by CYP3A4. Other physiological processes that change during pregnancy and may alter cannabinoid disposition are also reviewed.

EXPERT OPINION

THC and its metabolites disposition likely change during pregnancy. Hepatic CYP2C9 and CYP3A4 are induced in pregnant individuals and in vitro by pregnancy hormones. This induction of CYP2C9 and CYP3A4 is predicted to lead to altered THC and 11-OH-THC disposition and pharmacodynamic effects. More in vitro studies of THC metabolism and induction of the enzymes metabolizing cannabinoids are necessary to improve the prediction of THC pharmacokinetics in pregnant individuals.

Patient Perceptions of Prenatal Cannabis Use and Implications for Clinicians

OBJECTIVE

To understand pregnant patients' reasons for prenatal cannabis use and perceptions of safety, desired and undesirable health care experiences, and desired information about prenatal cannabis use and secondarily to understand racial differences in these perceptions and preferences.

METHODS

We conducted a qualitative study including 18 semi-structured, race-concordant virtual focus groups with pregnant individuals who self-reported cannabis use at prenatal care entry in a large integrated health care system in Northern California from November 2021 to December 2021. The focus groups included semi-structured questions that were recorded, transcribed, and coded by the research team. Thematic analysis was used to analyze the data.

RESULTS

Overall, 53 participants were included; 30 self-identified, as White and 23 self-identified as Black. Participants averaged 30.3 years of age (SD 5.2 years) and were on average at 20.9 weeks of gestation at study enrollment; 69.8% reported daily cannabis use, 24.5% reported weekly cannabis use, and 5.7% reported monthly or less cannabis use at entrance to prenatal care. Although some participants quit cannabis use in early pregnancy because of concerns about potential health risks, many perceived a lack of scientific evidence or believed that prenatal cannabis use was safe. Many preferred cannabis to over-the-counter or prescription medications for treating mood, morning sickness, pain, and sleep. Participants valued open interactions with obstetricians that acknowledged their motivations for use, and they desired information about potential risks through conversations and educational materials. White and Black participants' perspectives were generally similar, but a few Black participants uniquely described concerns about racial bias related to their prenatal cannabis use.

CONCLUSION

Pregnant patients used cannabis to manage mood and medical symptoms, and many believed that prenatal cannabis use was safer than the use of prescription medications. Obstetrician-initiated, patient-centered conversations around prenatal cannabis use, advice to discontinue cannabis use during pregnancy, and exploration of willingness to switch to medically recommended interventions for pregnancy-related symptoms may benefit patients.

A Pragmatic, Person-Centered View of Cannabis in the United States: Pursuing Care That Transcends Beliefs

BACKGROUND

Rates of cannabis use are increasing in the United States, likely as a result of changes in societal attitudes and expanding legalization. Although many patients report wanting to discuss the risks and benefits of cannabis use with their clinical providers, many providers hold conflicting beliefs regarding cannabis use and often do not engage patients in discussion about cannabis. This dilemma is underscored by the limitations imposed on cannabis related research, and lack of empirically based best-practice guidelines for clinicians when addressing cannabis use with patients.

OBJECTIVES

We aimed to briefly summarize clinician and patient attitudes toward cannabis use and review current clinical guidelines and provide suggestions to assist health care providers and clinicians in increasing their comfort and skill in discussing cannabis use with patients.

METHODS

A narrative review on attitudes toward cannabis use and clinical guidelines was performed to summarize the literature and provide evidence-based recommendations.

RESULTS

Attitudes toward cannabis use have been shaped by personal and political factors and contribute to clinician hesitance in speaking with patients about the topic. Administrative barriers have hindered the development of clearer public health guidelines that might enable the dissemination of evidence-based information on the health effects of cannabis use and might ultimately lead to better health outcomes.

CONCLUSION

Not discussing cannabis use with patients may be a crucial missed opportunity for harm reduction. In the absence of empirically supported best-practice guidelines, a person-centered approach can facilitate conversations on the harms and benefits of cannabis use.

Association between cannabis use disorder symptom severity and probability of clinically-documented diagnosis and treatment in a primary care sample

BACKGROUND

Brief cannabis screening followed by standardized assessment of symptoms may support diagnosis and treatment of cannabis use disorder (CUD). This study tested whether the probability of a medical provider diagnosing and treating CUD increased with the number of substance use disorder (SUD) symptoms documented in patients' EHRs.

METHODS

This observational study used EHR and claims data from an integrated healthcare system. Adult patients were included who reported daily cannabis use and completed the Substance Use Symptom Checklist, a scaled measure of DSM-5 SUD symptoms (0-11), during routine care 3/1/2015-3/1/2021. Logistic regression estimated associations between SUD symptom counts and: 1) CUD diagnosis; 2) CUD treatment initiation; and 3) CUD treatment engagement, defined based on Healthcare Effectiveness Data and Information Set (HEDIS) ICD-codes and timelines. We tested moderation across age, gender, race, and ethnicity.

RESULTS

Patients (N=13,947) were predominantly middle-age, male, White, and non-Hispanic. Among patients reporting daily cannabis use without other drug use (N=12,568), the probability of CUD diagnosis, treatment initiation, and engagement increased with each 1-unit increase in Symptom Checklist score (p's<0.001). However, probabilities of diagnosis, treatment, and engagement were low, even among those reporting ≥2 symptoms consistent with SUD: 14.0% diagnosed (95% CI: 11.7-21.6), 16.6% initiated treatment among diagnosed (11.7-21.6), and 24.3% engaged in treatment among initiated (15.8-32.7). Only gender moderated associations between Symptom Checklist and diagnosis (p=0.047) and treatment initiation (p=0.012). Findings were similar for patients reporting daily cannabis use with other drug use (N=1379).

CONCLUSION

Despite documented symptoms, CUD was underdiagnosed and undertreated in medical settings.

Reported Reasons for Cannabis Use Before and After Pregnancy Recognition

OBJECTIVES

Cannabis use is cautioned against during pregnancy, yet many pregnant people continue to use. This study aimed to evaluate the patterns and reasons for cannabis use before and after conception in pregnant people who screened positive for cannabis use at initiation of prenatal care.

METHODS

Pregnant patients at 1 prenatal practice in Baltimore, MD, who either self-reported cannabis use or tested positive on urine toxicology were approached for enrollment. Those who consented were given an anonymous survey with multiple choice questions regarding frequency and reasons for use before and after pregnancy recognition. Fisher exact, χ 2 test, and analysis of variance were used for analysis.

RESULTS

Of 117 pregnant people approached, 105 enrolled in the study. Of the 105 respondents, 40 (38.1%) reported complete abstinence after pregnancy recognition, whereas 65 (61.9%) reported continued use. Of the respondents who continued cannabis use, 35 (53.8%) had decreased frequency of use or quit, 26 (40%) reported no change in frequency of use, and 4 (6.2%) reported increase in frequency of use. Those who considered their use medical or mixed before pregnancy were 4 times as likely to continue use compared with those who considered their use nonmedical (66.7% vs 33.3%; odds ratio, 4.0; 95% confidence interval, 1.3-12.8). Respondents who continued use after pregnancy recognition were significantly more likely to discuss their use with their obstetrician (89.2% vs 50%, P < 0.001).

CONCLUSIONS

Reasons for use frequently changed after recognition of pregnancy. Most people who continued use during pregnancy reported that their reasons were for symptom control.

Cannabis and Pregnancy: A Review

Importance

Prenatal cannabis use is rising and is a major public health issue. Cannabis use in pregnancy and during lactation has been associated with increased maternal and offspring morbidity and mortality.

Objective

This review aims to summarize the existing literature and current recommendations for cannabis use during pregnancy or lactation.

Evidence Acquisition

A PubMed, Cochrane Library, and Google Scholar literature search using the following terms was performed to gather relevant data: "cannabis," "cannabinoid," "delta-9-tetrahydrocannabinol," "THC," "cannabidiol," "fetal outcomes," "perinatal outcomes," "pregnancy," and "lactation."

Results

Available studies on cannabis use in pregnancy and during lactation were reviewed and support an association with increased risk of preterm birth, neonatal intensive care unit admission, low birth weight, and small-for-gestational-age infants.

Conclusion and Relevance

There is a critical need for research on the effects of cannabis use in pregnancy and during lactation. This is a necessary first step before furthering patient education, developing interventions, and targeting antenatal surveillance to ameliorate the adverse impacts on maternal and fetal health.

Nurses' Attitudes Toward Patients Who Use Cannabis: Does Legal Status or Care Setting Matter?

BACKGROUND

Cannabis has been cited as the most frequently used drug in this country, and intolerance toward substance use is a recognized concern in nursing. The twofold purpose of this descriptive study was to determine (a) what, if any, were the differences between nurses' attitudes of patient cannabis use in states in which cannabis was legal versus illegal and (b) how do nurses working in diverse care settings differ in their attitudes regarding patient cannabis use.

METHODS

A sample of 809 registered nurses from across the United States were recruited to take part in this study in October 2018. A previously validated 20-question survey was used to collect participants' perceptions of and attitudes toward patient cannabis use. Demographic information collected included age, gender, educational level, years in practice, primary area of practice, and legal status of cannabis in state of practice. An independent t test and analysis of variance were used to analyze group differences.

FINDINGS

Findings from this study indicated that there was no significant difference in attitudes of nurses in states in which cannabis use was legal (M = 28.76, SD = 7.83) and states in which it was illegal (M = 29.43, SD = 7.65), t(807) = 1.202, p = .230. In addition, no significant differences were found in attitudes across six areas of practice, F(5) = 1.531, p = .178. Furthermore, nursing attitudes were largely positive toward patient cannabis use (M = 29.04, SD = 7.762; range: 20-100).

CONCLUSIONS

Findings from this study indicate that cannabis use may not carry the same perceived stigma as other illicit substances for nurses and unbiased care may be provided regardless of personal beliefs.

Youth cannabis use in Canada post-legalization: service providers' perceptions, practices, and recommendations

BACKGROUND

In 2018, Canada legalized recreational cannabis use with the purpose of protecting youth and restricting access. However, concerns have been raised that this objective has not been met as rates of cannabis use among youth aged 16-24 have not declined. Youth cannabis use is associated with various adverse effects including psychosis, anxiety, depression, suicidality, respiratory distress, cannabinoid hyperemesis syndrome, and intoxications. Service providers play a crucial role in addressing youth cannabis use. This study aimed to understand Ontario service providers' perceptions, practices, and recommendations on youth cannabis use.

METHODS

This mixed method study included a survey and two focus groups. The survey was distributed to mental health service providers serving youth aged 16-24 across Ontario who were given the option to participate in a focus group. The survey included closed and open-ended questions regarding perceptions, practices, and recommendations, while the focus groups explored these categories in greater depth. Descriptive statistics were used to analyze close-ended questions and interpretative content analysis was applied for open-ended questions. Focus group data were analyzed using thematic analysis.

RESULTS

The survey was completed by 160 service providers and 12 participated in two focus groups. Regarding perceptions, 60% of survey participants agreed with legalization, 26% had a strong understanding of medical versus recreational cannabis, 84% believed that cannabis has physical and mental health risks, and 49% perceived stigmatization. Less than half of the survey participants reported screening or assessing cannabis use, 16% stated they are highly familiar with treating cannabis use, and 67% reported that they rarely work with families. Subthemes identified in the focus groups under perceptions included normalization and stigmatization, harms for youth, and stigma, racism, and discrimination. Subthemes under practice included cannabis not being the primary focus, challenges with screening, assessment, and intervention, and referral to specialized services. Both the survey and focus group participants recommended increasing public education, enhancing service provider training, improving regulation and policies, reducing stigma and minimization, improving service access, and providing more culturally responsive services.

CONCLUSION

Youth cannabis use in Canada remains a significant public health concern, necessitating a more comprehensive plan to protect Ontario youth and reduce associated harms.

Addressing cannabis consumption among patients with hyperemesis gravidarum

Severe nausea and vomiting of pregnancy and hyperemesis gravidarum affect up to 3% of all pregnant people, causing substantial maternal and neonatal morbidity, suffering, and financial cost. Evidence supports the association of cannabis consumption with symptoms of severe nausea and vomiting of pregnancy or hyperemesis gravidarum as the general public has come to believe that cannabis is a natural, safe antiemetic. Cannabis consumption in pregnancy is discouraged strongly by the Surgeon General of the United States and the American College of Obstetricians and Gynecologists because of evidence of potential harms. Symptoms of intractable, severe nausea and vomiting of pregnancy or hyperemesis gravidarum associated with cannabis consumption may be unrecognized cannabinoid hyperemesis syndrome, and this syndrome may be more common than previously thought. Cannabis consumption is especially detrimental when causing or exacerbating debilitating symptoms such as the intense, persistent, recurrent, or cyclic vomiting and associated dehydration and other sequelae of cannabinoid hyperemesis syndrome. Open discussion of cannabis consumption during pregnancy is very challenging for patients and maternity care providers in our current environment of variable legal status across states and variable degrees of personal and societal acceptance. Evidence-based medical knowledge, guidance, tools, and skills are needed to differentially diagnose and treat cannabinoid hyperemesis syndrome in pregnancy. Researchers, clinicians, and medical specialty organizations must work together to strengthen the evidence base and develop or refine the necessary guidelines and tools for maternity care provider skill development, and to increase public and patient awareness of cannabinoid hyperemesis syndrome, specifically during pregnancy.

The ethics and management of cannabis use in pregnancy following decriminalisation and licensing for medical use: narrative review

AIMS AND METHOD

As drug policies pertaining to cannabis use become more liberalised, the prevalence of cannabis use in pregnancy could increase. However, there is limited guidance available for clinicians. This paper presents a narrative review of literature published in the past 16 years (2006-2021) to (a) address the impact of legalisation and decriminalisation on the risks, ethics and support of women who use cannabis during pregnancy and (b) develop guidance for clinicians.

RESULTS

Both national and international trends suggest increased use of cannabis over the past decade, while the risks of cannabis use for recreational or medicinal purposes in pregnancy remain unmitigated.

CLINICAL IMPLICATIONS

This review confirmed that the recommendation of cannabinoid-based products for pregnant and breast-feeding women is currently premature. More research is needed to address safety concerns. We discussed navigating ethical concerns and suggest targeted management strategies for clinicians treating pregnant women who choose to use cannabis.

Marijuana use and sleep quality during pregnancy

OBJECTIVE

Marijuana use among pregnant women is on the rise in part due to the perception that marijuana may improve problems related to pregnancy such as poor sleep. This study's objective was to examine associations between marijuana use and sleep quality among a sample of women during pregnancy.

MATERIAL AND METHODS

The sample included women seeking prenatal care at The Ohio State University Wexner Medical Center (2010-2015). Intake assessments included medical, demographic, and socioeconomic domains, as well as the Pittsburgh Sleep Quality Index. Marijuana use during pregnancy was determined using urine screens, chart abstraction, and self-report. Women completed standardized questionnaires regarding sleep quality, depressive symptoms, anxiety, stress, and discrimination at enrollment and each subsequent trimester. A linear mixed-effect model was used to assess the relationship between sleep variables and marijuana use adjusted for maternal race, education, household income, age, marital status, depressive symptoms, anxiety, stress, discrimination, and use of tobacco and other substances during pregnancy. Women completed the sleep quality assessments for a total of 294 pregnancies, which comprise the study population.

RESULTS

Among the study sample (n = 294), 93 women used marijuana and 201 women did not use marijuana during their pregnancies. Women who used marijuana (n = 93) were more likely to identify as African-American (73% vs 58%; p = .01), report government health insurance (98% vs 89%; p = .001), use tobacco during pregnancy (66% vs 33%; p < .001), report less household income (70% vs 43% < 10,000 annual household income; p < .001), and be unmarried (69% vs 49%; p < .001) compared to women who did not. Mean sleep quality was similar among women who did (µ = 7.6; SD = 4.0) and did not use marijuana during pregnancy (µ = 7.7; SD = 4.0), and both groups had a mean score worse than the conventional cutoff for poor sleep quality (>5). In fact, both groups reported worse sleep than is typically observed among cohorts reporting poor sleep, which have ranged from 5.3 to 6.3.

CONCLUSIONS

Current findings did not suggest differences in sleep quality between women who used and did not use marijuana during pregnancy. Findings are contrary to the perception that marijuana use alleviates sleep-related problems during pregnancy. Given well-documented adverse outcomes associated with prenatal marijuana exposure for children and the increase in women using marijuana during pregnancy, providers should be prepared to discuss possible harms associated with marijuana use during pregnancy as well as provide psychoeducational information and service referrals to those interested. Future studies could improve upon this design by assessing objective measures of sleep, such as actigraphy, as well as marijuana use repeatedly throughout pregnancy, which may be a more optimal strategy for illuminating potential relationships between marijuana use and sleep during pregnancy.

"Ganja Mamas": Online discussions about cannabis use in pregnancy

BACKGROUND

Nearly 5 % of pregnant women in the United States use cannabis. However, expecting mothers often do not seek counsel from their healthcare providers about prenatal cannabis use due to stigma and legal ramifications. Instead, cannabis-using pregnant women turn to each other to learn. Online message boards have become a safe place for parents to seek answers anonymously in real-time. The objective of this study was to examine the information-seeking/giving behaviors of cannabis-using pregnant women on an online community forum.

METHODS

We extracted 151 original messages and 1260 corresponding comments posted over a 7-day period from Whattoexpect.com's "Ganja Mamas" forum. We iteratively developed a codebook with 16 categories to reflect information-seeking behavior. N = 131 unique forum members posted questions for comment.

RESULTS

Approximately half, 46.56 %, reported their geographic location (24 states), and 40.46 % reported gestational age. The top topics for which members sought out information were testing, state-specific questions, postpartum, child protective services (CPS), hospital-specific questions, birth announcements, methods of cannabis use, quitting, breastfeeding/pumping, pregnancy symptoms, mental health, general health and pregnancy, and quantity of cannabis use. The second phase of analysis was based on members' responses. Clustered codes indicated how the respondents were using the forum: (1) interviewing and geographic location, (2) knowledge, experience, and reassurance, (3) congratulations and relief, and (4) concealing cannabis use and symptoms.

CONCLUSIONS

Our results demonstrate that mothers on an online cannabis forum are seeking information about location-specific experiences pertaining mostly to testing and child protective services. Additionally, mothers are responding by geographic-specific interviewing, and are expressing relief and reassurance in response to members' experiences.

Cannabis use in pregnancy and maternal and infant outcomes: A Canadian cross-jurisdictional population-based cohort study

BACKGROUND

With the recent legalization of cannabis in Canada, there is an urgent need to understand the effect of cannabis use in pregnancy. Our population-based study investigated the effects of prenatal cannabis use on maternal and newborn outcomes, and modification by infant sex.

METHODS

The cohort included 1,280,447 singleton births from the British Columbia Perinatal Data Registry, the Better Outcomes Registry & Network Ontario, and the Perinatal Program Newfoundland Labrador from April 1st, 2012 to March 31st, 2019. Logistic regression determined the associations between prenatal cannabis use and low birth weight, small-for-gestational age, large-for-gestational age, spontaneous and medically indicated preterm birth, very preterm birth, stillbirth, major congenital anomalies, caesarean section, gestational diabetes and gestational hypertension. Models were adjusted for other substance use, socio-demographic and-economic characteristics, co-morbidities. Interaction terms were included to investigate modification by infant sex.

RESULTS

The prevalence of cannabis use in our cohort was approximately 2%. Prenatal cannabis use is associated with increased risks of spontaneous and medically indicated preterm birth (1.80[1.68-1.93] and 1.94[1.77-2.12], respectively), very preterm birth (1.73[1.48-2.02]), low birth weight (1.90[1.79-2.03]), small-for-gestational age (1.21[1.16-1.27]) and large-for-gestational age (1.06[1.01-1.12]), any major congenital anomaly (1.71[1.49-1.97]), caesarean section (1.13[1.09-1.17]), and gestational diabetes (1.32[1.23-1.42]). No association was found for stillbirth or gestational hypertension. Only small-for-gestational age (p = 0.03) and spontaneous preterm birth (p = 0.04) showed evidence of modification by infant sex.

CONCLUSIONS

Prenatal cannabis use increases the likelihood of preterm birth, low birth weight, small-for-gestational age and major congenital anomalies with prenatally exposed female infants showing evidence of increased susceptibility. Additional measures are needed to inform the public and providers of the inherent risks of cannabis exposure in pregnancy.

Intention to Breastfeed and Paternal Influence on Pregnant Mothers Exclusively Using Marijuana Compared with Other Substances

Objective: To determine intention to breastfeed (ITBF) rates among mothers exclusively using marijuana (eMJ) compared with electronic cigarettes (eEcig), tobacco products (eTob), or multisubstances (MS), nonusers (NU), and the influence of paternal presence and paternal substance use. Study Design: Cross-sectional study of parental survey responses merged with electronic birth certificates. Accounting for clinical and social determinants of health, analyses of ITBF included (1) all mothers, (2) single mothers, and (3) mothers with fathers. Results: Among all mothers (n = 1,073), eMJ, eTob, and MS users had lower odds of ITBF compared with NU. Only eMJ users had lower odds of ITBF for those without paternal presence. However, in those mothers with a paternal presence, odds of ITBF were similar to NU for eMJ, eTob, and MS users when accounting for paternal factors, including paternal substance use. Conclusion: Women exclusively using MJ have lower ITBF compared with NU. However, paternal presence mitigated this effect, independent of parental MJ use. The presence of fathers may represent a unique predictor for increased ITBF in MJ using mothers.

Barriers to Implementing a Cannabis Focused SBIRT in Adolescent Primary Care

Introduction

The current study investigated providers' perceived barriers, supports, and need for adopting a screening, brief intervention, and referral to treatment model (SBIRT) intervention related to cannabis reduction into their community based primary care clinics.

Methods

Eleven pediatric primary care providers from regional community-based clinics participated in focus groups discussing a proposed adolescent cannabis use SBIRT reduction intervention, perceived need, and potential barriers to implementation within their clinic.

Results

Seven primary themes emerged regarding barriers to implementing a cannabis reduction SBIRT in primary care including provider ambivalence to adolescent cannabis use.

Conclusion

Further research is needed to understand evolving provider perceptions of adolescent cannabis use and how these views impact the adoption of SBIRT for the reduction of cannabis use among their adolescent patients.

Reasons Washington State Women Use Marijuana During Pregnancy/Breastfeeding, Their Trusted Information Sources, and Communication Strategies for Informed Decision-Making

OBJECTIVE

To understand reproductive-aged women's marijuana use beliefs and attitudes.

METHODS

Qualitative research (10 focus groups and 2 bulletin boards) with 95 Washington State women, aged 18 to 44 years, segmented by marijuana-using pregnant/breastfeeding; marijuana-using not-pregnant/breastfeeding; and nonmarijuana users. Participants completed up to 10 survey questions. We used deductive and inductive coding to analyze findings.

RESULTS

Marijuana-using pregnant/breastfeeding participants use marijuana to manage physical/mental pain and because of stigma, feel guilty, and sometimes hide use. Medicines have failed to address symptoms. Participants perceived marijuana safer than alcohol, tobacco, and illicit substances. Participants believed in the legitimacy of marijuana for health maintenance and want others to take their personally experienced benefits seriously. Participants interpreted lack of conclusive research as marijuana use not being unsafe. They want more information. All segments preferred hearing from other women about marijuana use experiences, with the marijuana-using pregnant/breastfeeding segment feeling strongest about this.

CONCLUSIONS

Personal experiences with, and anecdotes from family/friends about, the effects of marijuana use during pregnancy/breastfeeding influence marijuana-using participants' decision making.

NURSING IMPLICATIONS

It is important to speak with perinatal patients in a nonjudgmental/nonthreatening manner that acknowledges why reproductive-aged women may use marijuana and that conveys validation of patients' positive experiences with marijuana and a harm-reduction goal.

"You still have that fear": Policy constraints on informed decision making about legalized cannabis use during pregnancy and lactation

BACKGROUND

Cannabis is the most commonly used drug during pregnancy, excluding alcohol and tobacco, in the United States. Cannabis consumption during pregnancy is increasing along with greater legal and social acceptance.

METHODS

We conducted a qualitative content analysis of 23 in-depth interviews with pregnant and lactating people in Massachusetts, a state that legalized cannabis for adult use in 2016. Our aim was to explore how policy constrains or facilitates people's ability to make informed decisions about cannabis use during pregnancy and lactation. Our analysis was conducted using an ecosocial approach, recognizing that the implementation and interpretation of cannabis policy can be understood at multiple levels, which interact with each other and shape the health and experiences of individuals. Additionally, this analysis was informed by a harm reduction approach in which we acknowledge the complexity surrounding cannabis use during pregnancy and lactation, while attempting to identify ways to reduce potentially harmful consequences.

RESULTS

Findings revealed that, despite the legal status of cannabis, there continues to be a lack of clarity for pregnant and lactating people regarding the legal implications of cannabis use. Inconsistent state and institutional policies about drug testing of mothers and newborns leave a cloud of fear hanging over the experiences of people who use cannabis and inhibit their ability to obtain expert advice from healthcare providers.

CONCLUSION

Decision makers in public and institutional policy should work to clarify and update policies regarding substance use during pregnancy following legalization of a new substance, and ensure that pregnant and lactating people are afforded the same legal protections as the general population.

Clinician responses to cannabis use during pregnancy and lactation: a systematic review and integrative mixed-methods research synthesis

BACKGROUND

Perinatal cannabis use is increasing, and clinician counselling is an important aspect of reducing the potential harm of cannabis use during pregnancy and lactation. To understand current counselling practices, we conducted a systematic review and integrative mixed-methods synthesis to determine "how do perinatal clinicians respond to pregnant and lactating patients who use cannabis?"

METHODS

We searched 6 databases up until 2021-05-31. Eligible studies described the attitudes, perceptions, or beliefs of perinatal clinician about cannabis use during pregnancy or lactation. Eligible clinicians were those whose practice particularly focusses on pregnant and postpartum patients. The search was not limited by study design, geography, or year. We used a convergent integrative analysis method to extract relevant findings for inductive analysis.

RESULTS

Thirteen studies were included; describing perspectives of 1,366 clinicians in 4 countries. We found no unified approach to screening and counselling. Clinicians often cited insufficient evidence around the effects of perinatal cannabis use and lacked confidence in counselling about use. At times, this meant clinicians did not address cannabis use with patients. Most counselled for cessation and there was little recognition of the varied reasons that patients might use cannabis, and an over-reliance on counselling focussed on the legal implications of use.

CONCLUSION

Current approaches to responding to cannabis use might result in inadequate counselling. Counselling may be improved through increased education and training, which would facilitate conversations to mitigate the potential harm of perinatal cannabis use while recognizing the benefits patients perceive.

Patient caught breastfeeding and instructed to stop: an empirical ethics study on marijuana and lactation

BACKGROUND

The US guidelines recommend avoiding marijuana during breastfeeding given concerns about infant's neurodevelopment. In this setting, some physicians and hospitals recommend against or prohibit breastfeeding when marijuana use is detected during pregnancy. However, breastfeeding is beneficial for infants and women, and stigmatization of substance use in pregnancy has been historically linked to punitive approaches with a disproportionate impact on minority populations. We advance an empirically informed ethical analysis of this issue.

METHODS

First, we performed a retrospective cross-sectional qualitative study of prenatal and postpartum records from a random sample of 150 women delivered in an academic hospital system in 2017 to provide evidence and context regarding breastfeeding management in relation to marijuana use. We then perform a scoping literature review on infant risks from breastmilk marijuana exposure and risks associated with not breastfeeding for infants and women. Finally, we analyze this issue vis-a-vis ethical principles of beneficence, autonomy, and justice.

RESULTS

(1) Medical records reveal punitive language pertaining to the medicinal use of marijuana in pregnancy and misinterpretation of national guidelines, e.g., "patient caught breastfeeding and instructed to stop." (2) Though there are plausible neurodevelopmental harms from breastmilk exposure to THC, evidence of infant effects from breastmilk exposure to marijuana is limited and largely confounded by concomitant pregnancy exposure and undisclosed exposures. By contrast, health benefits of breastfeeding for women and infants are well-established, as are harms of forgoing breastfeeding. (3) Discouraging breastfeeding for women with marijuana use in pregnancy contradicts beneficence, as it neglects women's health considerations and incorrectly assumes that risks exceed benefits for infants. Restrictive hospital practices (e.g., withholding lactation support) compromise maternal autonomy and exploit power asymmetry between birthing persons and institutions, particularly when compulsory toxicology screening prompts child welfare investigations. Finally, recommending against breastfeeding during prenatal care and imposing restrictions during postpartum hospitalization may exacerbate racial disparities in breastfeeding and related health outcomes.

CONCLUSIONS

Policy interpretations which discourage rather than encourage breastfeeding among women who use of marijuana may cause net harm, compromise autonomy, and disproportionately threaten health and wellbeing of underserved women and infants.

Healthcare professionals' and budtenders' perceptions of perinatal cannabis use

Background: While national guidelines state that cannabis should not be consumed during pregnancy, cannabis use during pregnancy continues to increase. Pregnant individuals have reported using healthcare professionals and budtenders (i.e., cannabis store retailers) as resources for information on cannabis use during pregnancy and postpartum.Objectives: To determine healthcare professionals' and budtenders' perceptions of risks and benefits of perinatal cannabis use.Method: A qualitative study, using semi-structured, open-ended questions, was conducted with ten healthcare professionals (predominantly nurses; 100% women) and ten budtenders (70% women) in a state where cannabis use is legal for adults 21 years of age and older. Data were interpreted using a qualitative description methodology to identify themes. Themes were generated from participant responses (implicit and explicit). We analyzed data separately and sequentially and present linked themes across samples. Data saturation, rigor, and trustworthiness were discussed and agreed upon by the analytic team.Results: Six themes arose from the healthcare professional and budtender data: 1) Perinatal customers and patients perceive cannabis to be medicinal, 2) Supporting perinatal people who use cannabis, 3) Spectrum of perceived impacts of perinatal cannabis use, 4) Comparison to use of other substances during pregnancy, 5) Perceived limited knowledge and training about cannabis regulation and product safety, and 6) Current trends of purchase and use.Conclusion: Participants reported that perinatal patients/customers perceived cannabis to be medicinal, and highlighted non-judgmental/harm reduction strategies for engaging patients/customers. Training is needed for healthcare professionals and budtenders to assist with patient/customer discussions about perinatal cannabis use.

Postpartum Marijuana Use, Perceptions of Safety, and Breastfeeding Initiation and Duration: An Analysis of PRAMS Data From Seven States, 2017

BACKGROUND

Little is known about breastfeeding initiation and duration in the context of postpartum marijuana use and safety beliefs.

RESEARCH AIMS

(1) To describe characteristics of women who used marijuana postpartum; (2) to evaluate the relationship between postpartum marijuana use and breastfeeding behaviors; and 3) to assess, among women who used marijuana postpartum, how safety perceptions are associated with breastfeeding behaviors.

METHODS

Data from the cross-sectional Pregnancy Risk Assessment Monitoring System, a United States national governmental survey, 2017, were analyzed for participants with infants aged ≥ 12 weeks (seven states, unweighted N = 4604). Chi-square tests were used to compare characteristics and counseling for postpartum marijuana use. For participants with postpartum use, adjusted prevalence ratios (aPR) were calculated to evaluate relationships between safety perceptions and breastfeeding initiation and duration.

RESULTS

Overall, 5.5% (95% CI [4.6, 6.6]) of participants reported postpartum marijuana use; among these women, 47.2% (CI [37.6, 56.9]) were breastfeeding at the time of the survey. Overall, 25.7% of participants indicated that they had been advised, by their prenatal care provider, against marijuana use while breastfeeding. Breastfeeding initiation or duration did not differ by postpartum marijuana use. Among participants with postpartum use, those who perceived marijuana was safe for breastfeeding women to use were more likely to have breastfed (aPR = 1.22, CI [1.04, 1.43]) and have a breastfeeding duration > 12 weeks (aPR = 1.57, CI [1.08, 2.27]) compared to those who perceived it to be unsafe.

CONCLUSIONS

Understanding maternal safety beliefs and provider education about the latest evidence and guidance related to postpartum marijuana use may improve clinical care.

Miswiring the brain: Human prenatal Δ9-tetrahydrocannabinol use associated with altered fetal hippocampal brain network connectivity

Increasing evidence supports a link between maternal prenatal cannabis use and altered neural and physiological development of the child. However, whether cannabis use relates to altered human brain development prior to birth, and specifically, whether maternal prenatal cannabis use relates to connectivity of fetal functional brain systems, remains an open question. The major objective of this study was to identify whether maternal prenatal cannabis exposure (PCE) is associated with variation in human brain hippocampal functional connectivity prior to birth. Prenatal drug toxicology and fetal fMRI data were available in a sample of 115 fetuses [43 % female; mean age 32.2 weeks (SD = 4.3)]. Voxelwise hippocampal connectivity analysis in a subset of age and sex-matched fetuses revealed that PCE was associated with alterations in fetal dorsolateral, medial and superior frontal, insula, anterior temporal, and posterior cingulate connectivity. Classification of group differences by age 5 outcomes suggest that compared to the non-PCE group, the PCE group is more likely to have increased connectivity to regions associated with less favorable outcomes and to have decreased connectivity to regions associated with more favorable outcomes. This is preliminary evidence that altered fetal neural connectome may contribute to neurobehavioral vulnerability observed in children exposed to cannabis in utero.

Correlates of continued cannabis use during pregnancy

BACKGROUND

Cannabis use is increasingly common among pregnant women despite concern that it may be linked to adverse maternal and infant outcomes. Determining whether variables associated with cannabis use predict whether women continue or quit using during pregnancy may inform strategies to reduce prenatal use.

METHODS

Pregnant women who regularly used cannabis before pregnancy (n = 296) were recruited via Facebook. After finding out they were pregnant, 41 % reported quitting, 13 % quit then relapsed, 32 % reduced use, and 15 % continued use at the same rate. Differences among these four cannabis use status groups (quit, relapsed, reduced, continued) in sociodemographics, cannabis use, cigarette use, perceived risk/benefit, delay discounting, and communications about cannabis with their doctor were assessed.

RESULTS

Compared to those who quit, continuing use during pregnancy was associated with being unemployed (Relative Risk (RR) = .32, 95 %CI [.13, .78]), using cigarettes pre-pregnancy (RR = 3.43, 95 %CI [1.32, 8.94]), being in an earlier trimester (RR = 4.38, 95 %CI [1.18, 16.23]), less perceived risk (RR = .79, 95 %CI [.74, .85]), and more days per week of use pre-pregnancy (RR = .10, 95 %CI [.01, .84]). Unintended pregnancy, shorter time to cannabis use after waking pre-pregnancy, using cannabis more times per day pre-pregnancy, and greater perceived benefits of use had significant bivariate associations with continued use during pregnancy, but did not retain significance in a multinomial model.

CONCLUSIONS

Identification of these correlates provides potential targets for prevention of or intervention for prenatal cannabis use. However, much more research is needed to understand prenatal cannabis use and its effects in order to better educate women and healthcare providers, and to design optimal public health strategies.

Pregnant people's experiences discussing their cannabis use with prenatal care providers in a state with legalized cannabis

BACKGROUND

As cannabis legalization spreads, so do concerns about potential harms from use during pregnancy. Legalization may facilitate improved patient-provider interactions about cannabis use. Yet little is known about pregnant people's discussions of cannabis use with healthcare providers in an environment where recreational cannabis is legal.

METHODS

In May-August 2019, we conducted semi-structured in-depth interviews with 33 pregnant or postpartum people in California who used cannabis during pregnancy, and explored their discussions with healthcare providers about their cannabis use. We audio-recorded and transcribed interviews, and conducted thematic analysis using inductive and deductive methods.

RESULTS

Participants were diverse by age, race/ethnicity, and socio-economic position. Most reported daily cannabis use, both before and during pregnancy. Most participants did not disclose their cannabis use to their prenatal care providers, due to fears of being reported to child protective services (CPS), or fears of provider judgment. Participants reported that few providers initiated any discussions about cannabis use in pregnancy with them; some participants interpreted this omission as tacit endorsement of cannabis use in pregnancy. When participants and providers did discuss cannabis use in pregnancy, participants heard a wide range of sometimes-conflicting health messages, as well as some legal threats.

CONCLUSIONS

This study documents notable deficits in patient-provider interactions about cannabis. Pregnant patients' fears of being reported to CPS and separated from their children for cannabis use persist despite cannabis legalization. Providers' role as potential reporters to CPS appears to pose a significant barrier to comprehensive, compassionate counseling and education on cannabis use in pregnancy.

Marijuana use in opioid exposed pregnancy increases risk of preterm birth

BACKGROUND

The prevalence of opioid use disorder has increased across the United States, but the rural population of Appalachia has been disproportionately impacted. Concurrently, the slow, but steady progress in the legalization of marijuana may be affecting perception of marijuana use in pregnancy. However, marijuana use in pregnancy has been associated with adverse perinatal outcomes. Concomitant use of opioids and marijuana in pregnancy has not been evaluated.

OBJECTIVE

The primary aim of the study was to evaluate the association between confirmed marijuana use in late pregnancy and preterm birth in opioid-exposed pregnancies.

METHODOLOGY

A retrospective chart review was conducted that included all births from July 2011 to June 2016 from 6 delivery hospitals in South-Central Appalachia. Out of 18,732 births, 2368 singleton pregnancies indicated opioid use and met remaining inclusion criteria, with 108 of these mothers testing positive for marijuana at delivery. Independent sample t-test and Chi-Square analyses compared marijuana and non-marijuana exposed groups on maternal and neonatal outcomes. Regression analyses controlled for confounding variables in predicting neonatal abstinence syndrome (NAS), NICU admission, preterm birth, small for gestational age, and low birth weight outcomes as shown in Table 1.

RESULTS

Neonates born to marijuana-positive women in opioid-exposed pregnancy were more likely to be born preterm, small for gestational age, have low birth weight, and be admitted to NICU. After statistically controlling for parity, marital status, tobacco and benzodiazepine use, preterm birth and low birth weight remained statistically significant with aOR of 2.35 (1.30-4.24) and 2.01 (1.18-3.44), respectively.

CONCLUSIONS

Maternal use of marijuana in any opioid-exposed pregnancy may increase risk of preterm birth and low-birth weight infants. Prospective studies need to examine the dose and timing of marijuana and opioid use in pregnancy to better delineate perinatal effects. Nonetheless, pregnant women using opioids, including recommended medication assisted treatment for opioid use disorder, should be educated about the risks of concurrent marijuana use during pregnancy and may need to be counseled to abstain from marijuana use during pregnancy for an optimal outcome.

Family Planning Providers' Assessment of Intimate Partner Violence and Substance Use

Background: Intimate partner violence (IPV) and substance use are intersecting health problems that adversely impact sexual and reproductive health outcomes for women seeking care at family planning (FP) clinics. We aimed to characterize whether and how FP clinic providers (1) assessed for IPV and substance use and (2) combined IPV and substance use assessments. Methods: Providers and patients (female, 18-29 years old, English speaking) at four FP clinics participating in a larger randomized controlled trial on provider communication skills were eligible. Providers received training on universal education, a research-informed IPV assessment approach. Visits were audio recorded, transcribed verbatim, and coded by two independent coders. We used inductive and deductive coding to assess providers' communication approaches and examined codes for patterns and categories. We then converted these approaches into variables to calculate frequencies among recorded visits. Results: Ninety-eight patient-provider encounters were analyzed. In almost all encounters (90/98), providers assessed for IPV. Many providers adopted best practice IPV assessment techniques, such as universal education (68/98) and normalizing/framing statements (45/98). Tobacco use screening was common (70/98), but alcohol (17/98) and other drug use screening (17/98) were rare. In only one encounter did a provider discuss IPV and substance use as intersecting health problems. Conclusion: This study provides insight on how FP clinicians, as key providers for millions of women in the United States, assess patients for IPV and substance use. Results show providers' willingness to adopt IPV universal education messaging and demonstrate room for improvement in substance use assessments and integrated discussions of IPV and substance use. Trial Registration Number: NCT01459458.

Evidence for the Effectiveness and Acceptability of e-SBI or e-SBIRT in the Management of Alcohol and Illicit Substance Use in Pregnant and Post-partum Women

Alcohol and illicit psychoactive drug use during pregnancy have increased worldwide, putting women and their children's health and development at risk. Multiple drug use, comorbid psychiatric disorders, sexual and physical abuse are common in women who use alcohol and drugs during pregnancy. The effects on the mother include poor reproductive and life-long health, legal, family, and social problems. Additionally, the exposed child is at increased risk of long-term physical health, mental health, and developmental problems. The stigma associated with substance use during pregnancy and some clinicians' reticence to inquire about substance use means many women are not receiving adequate prenatal, substance abuse, and mental health care. Evidence for mHealth apps to provide health care for pregnant and post-partum women reveal the usability and effectiveness of these apps to reduce gestational weight gain, improve nutrition, promote smoking cessation and manage gestational diabetes mellitus, and treat depression and anxiety. Emerging evidence suggests mHealth technology using a public health approach of electronic screening, brief intervention, or referral to treatment (e-SBIRT) for substance use or abuse can overcome the typical barriers preventing women from receiving treatment for alcohol and drug use during pregnancy. This brief intervention delivered through a mobile device may be equally effective as SBIRT delivered by a health care professional in preventing maternal drug use, minimizing the effects to the exposed child, and providing a pathway to therapeutic options for a substance use disorder. However, larger studies in more diverse settings with women who have co-morbid mental illness and a constellation of social risk factors that are frequently associated with substance use disorders are needed.

Canadian educational resources about cannabis use and fertility, pregnancy and breast feeding: a scoping review protocol

INTRODUCTION

Cannabis use in Canada is becoming more prevalent across all demographic groups due to increases in accessibility and lowered perceptions of harm. These patterns are mirrored among women of reproductive age, including women who are pregnant. Given increasing evidence for detrimental short- and long-term impacts of cannabis exposure on fetal, newborn and child outcomes, there is a need for high-quality, accessible resources providing reliable guidance and recommendations on this topic for both the public and healthcare providers. We will conduct a scoping review to identify and characterise all publicly available online educational resources discussing cannabis use related to fertility, pregnancy and breastfeeding developed by Canadian organisations.

METHODS AND ANALYSIS

Using Arksey and O'Malley's scoping review methodology as a guide, we will search Medline (Ovid), Medline in Process (Ovid), Embase (Ovid), ERIC (Ovid), CINAHL (EBSCOhost) and Education Source (EBSCOhost). We will also conduct a grey literature search targeting the websites of national and independent Canadian obstetrical societies and networks, and government and public health offices that provide recommendations or guidance to individuals and their healthcare providers seeking information on cannabis use related to fertility, pregnancy or breastfeeding.

ETHICS AND DISSEMINATION

Research ethics approval is not required for scoping review studies. We anticipate that this review's findings will be disseminated through traditional channels, including preprint and peer-reviewed publications and presentations at academic conferences. In addition, the resources and guidelines identified in the study will be gathered and made available online on a single comprehensive public repository. PROTOCOL REGISTRATION NUMBER: osf.io/p24y5.

Early lessons from maternal mortality review committees on drug-related deaths-time for obstetrical providers to take the lead in addressing addiction

Problem:

In the United States, maternal mortality review committees (MMRC) are providing compelling data that drug-related deaths are emerging as a leading cause of pregnancy-associated death (death during pregnancy or up to a year postpartum). Recommendations from the MMRC consistently highlight screening all pregnant and postpartum women for drug use and improving access to evidence-based substance use disorder and mental health treatment. Unfortunately, many providers lack the confidence, skills and necessary resources to screen for substance use, provide basic behavioral health services or facilitate referral to high-quality services in their clinical settings. Our profession’s collective lack of response to a leading cause of maternal death represents a missed opportunity for potentially life-saving interventions.

A Solution:

We call on our fellow obstetrician gynecologists to incorporate the lessons learned from MMRC and integrate addiction assessment and treatment into prenatal and postpartum care. Provider level integration of behavioral health services is, however, insufficient to fully address the magnitude of drug-related maternal deaths in the US. We, therefore, ask colleagues to address the structural/systemic barriers to care identified in MMRC. By doing so, we can prevent drug-related maternal deaths.

Attitudes and knowledge about cannabis and cannabis-based therapies among US neurologists, nurses, and pharmacists

Use of cannabinoid therapies is on the rise in the United States, but responses of healthcare professionals and their knowledge of these therapies have been mixed. More information is needed about factors associated with healthcare professionals' attitudes and knowledge about medical cannabis. We conducted an online survey of US-based neurologists, nurse practitioners (NPs)/nurses, and pharmacists in August-September of 2018 (n = 451). We constructed perceived knowledge and attitudes scales and a knowledge index from multiple items and assessed state cannabis laws, participant's sociodemographics, workplace type and policies, and patient population. We used ordinary least-squares regression to examine associations among study variables. Over 80% of participants supported use and legalization of medical cannabis, especially cannabidiol (CBD) for epilepsy and when prescribed by a medical provider, but 40-50% (depending on item) felt unfamiliar with cannabinoid pharmacology and clinical applications. A total of 43% favored legal recreational cannabis. Pharmacists scored higher on the knowledge test than neurologists and NPs/nurses, but NPs/nurses had more favorable attitudes than neurologists and higher perceived knowledge than pharmacists. Both knowledge indicators predicted attitudes. State cannabis access and favorable workplace policies were associated with higher knowledge and more favorable attitudes. Healthcare professionals see potential in cannabis therapies but report significant knowledge gaps. Professional cannabinoid education is needed to address growing patient and provider demand for knowledge about cannabinoid therapies.

Protection Versus Progress: The Challenge of Research on Cannabis Use During Pregnancy

A central tension in pediatric research ethics arises from our desire to protect children from harm while also allowing progress toward discoveries that could improve child health. A prime example of this tension is research on a controversial yet increasingly common practice: the use of cannabis by women to treat nausea and vomiting of pregnancy. Studies of cannabis use in pregnancy face a combination of ethical hurdles because of the inclusion of pregnant women and involvement of a schedule I controlled substance. Given the growing need for research on the safety and efficacy of cannabis for nausea and vomiting of pregnancy, we reflect on the multiple historical contexts that have contributed to the challenge of studying cannabis use during pregnancy and make a case for the ethical rationale for such research.

Knowledge, Practices, and Attitudes of Washington State Health Care Professionals Regarding Medical Cannabis

Introduction: Health care providers in Washington State practice in a unique environment where both medical and recreational cannabis use are legal. Five types of health care providers can authorize medical cannabis. State-certified medical cannabis consultants may advise patients in a cannabis retail store regarding use and consumption. Washington State's health care professionals' perspectives about medical cannabis can inform policy-makers nationwide who are navigating challenges posed by legalization of medical and recreational cannabis. Materials and Methods: A cross-sectional mixed-mode survey using a 26-item questionnaire was administered to a random sample of actively licensed health care professionals legally permitted to provide medical cannabis authorizations in Washington State. We describe participant demographics and summarize responses to survey questions. We report comparisons across provider types using Fisher's exact tests with a level of significance of p<0.01. Results: Among the 1440 health care professionals invited to participate in the study, 310 respondents met eligibility criteria (response rate 24%). Only 57 respondents (18.4%) indicated having ever issued a medical cannabis authorization. Among them, 6, all naturopaths, had provided more than 500. Over half (58%) reported that they did not feel they had the knowledge and skills necessary to provide authorizations. Depending on the condition, 29-93% of respondents correctly identified conditions that qualified a patient to receive a medical cannabis authorization. Very few knew that employers are not required to provide accommodations for medical cannabis. Health care professionals (64.8%) served as the most frequent source of information regarding cannabis risks and benefits. Over half (62%) strongly or somewhat agreed that the Drug Enforcement Agency should reschedule cannabis to make it legal at the federal level. Conclusion: A wide range of knowledge was exhibited within our sample of health care professionals regarding qualifying conditions for medical cannabis. As more states adopt comprehensive medical cannabis laws, health care professionals must be prepared to provide information to patients regarding the effects, risks, and benefits of cannabis. Standardized education could ensure that health care professionals are prepared to responsibly promote the use of cannabis when indicated for medically appropriate symptoms and conditions. A rational approach to medical cannabis is needed to assure that unforeseen consequences are mitigated.

Marijuana Use and Potential Implications of Marijuana Legalization

Most states in the United States have legalized medical and/or recreational cannabis in response to public demand. Trends in states adopting such legislation demonstrate an increasing prevalence of cannabis use coincident to decreasing perceptions of risk of harm from cannabis products. When providing anticipatory guidance, pediatricians should be prepared to address childhood unintentional ingestion management and prevention, adolescent problem use, and cannabis as an alternative therapy for seizure disorders and other conditions.

Women's Questions About Perinatal Cannabis Use and Health Care Providers' Responses

Background: Cannabis use is common among individuals of reproductive age. We examined publicly posted questions about perinatal cannabis use and licensed United States health care provider responses. Materials and Methods: Data were medical questions on perinatal cannabis use posted online from March 2011 to January 2017 on an anonymous digital health platform. Posters were able to "thank" health care providers for their responses and providers could "agree" with other provider responses. We characterized 364 user questions and 596 responses from 277 unique providers and examined endorsement of responses through provider "agrees" and user "thanks." Results: The most frequent questions concerned prenatal cannabis use detection (24.7%), effects on fertility (22.6%), harms of prenatal use to the fetus (21.3%), and risks of baby exposure to cannabis through breast milk (14.4%). Provider sentiment in responses regarding the safety of perinatal cannabis use were coded as 55.6% harmful, 8.8% safe, 8.8% mixed/unsure, and 26.8% safety unaddressed. Half of providers (49.6%) discouraged perinatal cannabis use, 0.5% encouraged use, and 49.9% neither encouraged nor discouraged use. Provider responses received 1,004 provider "agrees" and 583 user "thanks." Provider responses indicating that perinatal cannabis use is unsafe received more provider "agrees" than responses indicating that use is safe (B = 0.42, 95% CI 0.02-0.82, p = 0.04). User "thanks" did not differ by provider responses regarding safety or dis/encouragement. Conclusion: The data indicate public interest in cannabis use effects before, during, and after pregnancy. While most health care providers indicated cannabis use during pregnancy and breastfeeding is not safe, many did not address safety or discourage use, suggesting a missed educational opportunity.

Interaction with the justice system and other factors associated with pregnant women's self-report and continuation of use of marijuana

BACKGROUND

Marijuana use in pregnancy is common and self-report of use to healthcare providers is variable. This study evaluates the relationship between prior interaction with the justice system as well as other factors associated with self-report and continuation of use of marijuana in pregnancy.

METHODS

This retrospective cohort study included women with a positive urine toxicology test for marijuana at their initial prenatal visit. Prior interaction with the judicial system was determined by querying a publicly available database. Those who did and did not self-report use were compared using chi square and Fisher's exact test for analysis of categorical variables and t test for comparison of means. A logistic regression was performed to determine factors related to remaining positive at the time of birth.

RESULTS

Of 597 women included in analysis, 308 (51.6%) self-reported use. African American women were more likely to self-report use (p = 0.02). Interaction with the justice system was not statistically predictive of self-report. Of 483 (80.9%) who had birth outcome data available, 117 (24.2%) had positive marijuana tests at the time of delivery. Women who tested positive at birth were older (27.3 v 25, p < 0.01), more likely to present later for care (p = 0.02) and more likely to have self-reported their use at their initial visit (p = 0.03).

DISCUSSION

Discrepancies exist between pregnant women's self-report of marijuana use and biologic testing results. Women with positive toxicology testing who self-report use may do so due to more problematic use and may benefit from enhanced interventions.

Cannabis Use in Pregnant and Breastfeeding Women: Behavioral and Neurobiological Consequences

Nowadays, cannabis is the most consumed illicit drug. The global prevalence of the use of cannabis in 2017 was estimated in 188 million of people, 3.8% of worldwide population. Importantly, the legalization of cannabis in different countries, together with the increase in the apparent safety perception, may result in a great variety of health problems. Indeed, an important concern is the increase in cannabis use among pregnant and breastfeeding women, especially since the content of delta9-tetrahidrocannabinol (THC) is currently around 2-fold higher than it was 15-20 years ago. The purpose of this study was to review cannabis use during pregnancy and breastfeeding including epidemiological aspects, therapeutic or preventive strategies, and experimental considerations and results from animal models of perinatal cannabis exposure to analyze the underlying neurobiological mechanisms and to identify new therapeutic approaches. A recent report revealed that among pregnant women aged 15-44, last month cannabis use prevalence was over 4.9%, raising to 8.5% in the 18-25-year-old age range. Pre- and post-natal exposure to cannabis may be associated with critical alterations in the newborn infants that are prolonged throughout childhood and adolescence. Briefly, several reports revealed that perinatal cannabis exposure was associated with low birth weight, reduction in the head circumference, cognitive deficits (attention, learning, and memory), disturbances in emotional response leading to aggressiveness, high impulsivity, or affective disorders, and higher risk to develop a substance use disorder. Furthermore, important neurobiological alterations in different neuromodulatory and neurotransmission systems have been associated with cannabis consumption during pregnancy and lactation. In spite of the evidences pointing out the negative behavioral and neurobiological consequences of cannabis use in pregnant and breastfeeding women, there are still limitations to identify biomarkers that could help to establish preventive or therapeutic approaches. It is difficult to define the direct association specifically with cannabis, avoiding other confusing factors, co-occurrence of other drugs consumption (mainly nicotine and alcohol), lifestyle, or socioeconomic factors. Therefore, it is necessary to progress in the characterization of short- and long-term cannabis exposure-related disturbances.

Prevalence and outcomes of prenatal recreational cannabis use in high-income countries: a scoping review

BACKGROUND

With expanding recreational cannabis legalisation, pregnant women and their offspring are at risk of potentially harmful consequences.

OBJECTIVES

To assess the prevalence of recreational cannabis use among pregnant women, health outcomes associated with prenatal recreational cannabis use, and the potential impact of recreational cannabis legalisation on this population.

SEARCH STRATEGY

Five databases and the grey literature were systematically searched (2000-2019).

SELECTION CRITERIA

Human studies published in English or French reporting on the prevalence of prenatal recreational cannabis use in high-income countries.

DATA COLLECTION AND ANALYSIS

Data on study characteristics, prenatal substance use, and health outcomes were extracted and qualitatively synthesised.

MAIN RESULTS

Forty-one publications met our inclusion criteria. The overall prevalence of prenatal cannabis use varied substantially (min-max: 0.24-22.6%), with the greatest use in the first trimester. In the three studies with temporal data available, rates of prenatal cannabis use increased across years. Only 7/41 and 5/41 studies provided information on gestational age of exposure and frequency of use, respectively. The concomitant use of alcohol, illicit drugs, and tobacco was higher among cannabis users than nonusers. Prenatal cannabis use was associated with select neonatal, but not maternal, health outcomes. There were insufficient data to compare prenatal cannabis use between the pre- and post-legalisation periods.

CONCLUSION

Cannabis use among pregnant women is prevalent and may be associated with adverse neonatal outcomes. Future studies should assess the gestational age and frequency of cannabis exposure, and usage patterns prior to and following legalisation.

TWEETABLE ABSTRACT

Women who consume cannabis during pregnancy could risk predisposing their newborns to poor birth outcomes.

Cigarette Smoking Status and Substance Use in Pregnancy

Objectives Substance use during pregnancy is a significant public health issue. Prenatal substance use increased in the past decade while prenatal cigarette smoking has remained stable. Co-use of tobacco and other drugs is a concern because of potential additive risks. This study aims to describe the prevalence rates of substance use among pregnant women and examine the association between smoking status (nonsmoker, recent quitter and current smoker) and other drug use. Methods In this cross-sectional study, pregnant women (n = 500) were recruited from two obstetric practices to complete three substance use screeners and have their urine tested for 12 different drug classes, including cannabis, opioids and cocaine. Participants were divided into three groups based on survey responses: nonsmokers, recent quitters (smoked in the month prior to pregnancy but not past month) and current smokers (past-month). Results Approximately 29% of participants reported smoking in the month before pregnancy. During pregnancy, 17, 12 and 71% were current smokers, recent quitters and nonsmokers respectively. Overall prevalence of illicit or prescription drug use in pregnancy was 27%. Cannabis was the most common drug used in pregnancy with prevalence of 22%, followed by opioids (4%), cocaine (1%), tricyclic antidepressants (TCAs) (1%), amphetamines (1%), and benzodiazepines (1%). On multivariable logistic regression, smoking in pregnancy was associated with a positive urine drug screen; with adjusted odds ratio (aOR) 4.7 (95% CI 2.6-8.3) for current smokers and 1.6 (95% CI 0.8-3.3) for recent quitters. Factors negatively associated with positive drug screen were second and third trimester pregnancies, 0.5 (0.3-0.9) and 0.3 (0.2-0.6) respectively; and employment, 0.5 (0.3-0.8). Conclusions for Practice Co-use of tobacco and illicit drugs, particularly cannabis, is relatively high during pregnancy. Additional research is needed to understand the health implications of co-use versus use of tobacco only. Given the strong association between smoking and other drug use, clinicians should routinely assess for illicit drug use in women who smoke during pregnancy.

Children's and caregivers' perspectives about mandatory reporting of child maltreatment: a meta-synthesis of qualitative studies

OBJECTIVE

To systematically synthesise qualitative research that explores children's and caregivers' perceptions of mandatory reporting.

DESIGN

We conducted a meta-synthesis of qualitative studies.

DATA SOURCES

Searches were conducted in Medline, Embase, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Criminal Justice Abstracts, Education Resources Information Center, Sociological Abstracts and Cochrane Libraries.

ELIGIBILITY CRITERIA

English-language, primary, qualitative studies that investigated children's or caregivers' perceptions of reporting child maltreatment were included. All healthcare and social service settings implicated by mandatory reporting laws were included.

DATA EXTRACTION AND SYNTHESIS

Critical appraisal of included studies involved a modified checklist from the Critical Appraisal Skills Programme (CASP). Two independent reviewers extracted data, including direct quotations from children and caregivers (first-order constructs) and interpretations by study authors (second-order constructs). Third-order constructs (the findings of this meta-synthesis) involved synthesising second-order constructs that addressed strategies to improve the mandatory reporting processes for children or caregivers-especially when these themes addressed concerns raised by children or caregivers in relation to the reporting process.

RESULTS

Over 7935 citations were retrieved and 35 articles were included in this meta-synthesis. The studies represent the views of 821 caregivers, 50 adults with histories of child maltreatment and 28 children. Findings suggest that children and caregivers fear being reported, as well as the responses to reports. Children and caregivers identified a need for improvement in communication from healthcare providers about mandatory reporting, offering preliminary insight into child-driven and caregiver-driven strategies to mitigate potential harms associated with reporting processes.

CONCLUSION

Research on strategies to mitigate potential harms linked to mandatory reporting is urgently needed, as is research that explores children's experiences with this process.

Beliefs and attitudes regarding prenatal marijuana use: Perspectives of pregnant women who report use

OBJECTIVE

With the increasingly permissive legal and social environments regarding marijuana, it is important to understand prenatal marijuana use from the perspective of women who use marijuana. Our objective was to qualitatively describe the marijuana use experiences, beliefs, and attitudes of women who used marijuana during pregnancy.

METHODS

We conducted semi-structured interviews with pregnant women who had either reported current marijuana use or had urine testing positive for marijuana. Interviews were transcribed verbatim and analyzed for patterns and themes.

RESULTS

Twenty-five pregnant women who used marijuana during their pregnancies participated in our study interviews. Main themes that emerged from the interviews were that women: 1) reported higher amounts of marijuana use prior to pregnancy and attempted to reduce their use once they realized they were pregnant; 2) used marijuana to help with nausea and appetite changes during pregnancy or to improve mood; 3) described marijuana as "natural" and "safe" compared to other substances such as alcohol, tobacco, other recreational drugs, and prescribed medications; 4) had conflicting opinions regarding whether marijuana was addictive; and 5) were uncertain but had some concerns regarding potential risks of prenatal marijuana use.

CONCLUSION

Pregnant women who used marijuana in pregnancy held contradictory beliefs about continued use; they reported trying to reduce usage and were worried about potential risks, but also felt that marijuana is more natural and safer than other substances, including prescribed medicines. These findings have implications for how practitioners address prenatal marijuana use and highlight the need for further research on developmental outcomes.
