Maternal Cannabis Use in the Perinatal Period: Data From the Pregnancy Risk Assessment Monitoring System Marijuana Supplement, 2016-2018

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..

Exploring preferences for different modes of cannabis use during early pregnancy: A qualitative study

OBJECTIVE

Rates of prenatal cannabis use are rising, yet little is known about modes of cannabis use during pregnancy. This focus group study with pregnant individuals aimed to examine use patterns and perceptions regarding common modes of prenatal cannabis use.

METHOD

Kaiser Permanente Northern California pregnant adult patients who identified as White or Black and self-reported cannabis use during pregnancy were recruited to participate (N = 53; 40% Black, 60% White; Meanage = 30.3, SD = 5.2). Eighteen focus groups with race-concordant facilitators followed a semi-structured format that queried participants on their prenatal cannabis use, including preferred modes of use (e.g., vapes, blunts, dabs, joints, edibles, topicals, pipes). Focus group discussions were coded and analyzed using a general inductive approach.

RESULTS

A range of modes were preferred, with no single mode predominant. Participants' preferences aligned with four themes: perceived effects and benefits of cannabis, health and safety, convenience and familiarity, and partner and friend influences. Participants sought modes that were accessible and familiar, provided consistent and quick relief for pregnancy-related symptoms, were aligned with partners or friends, and minimized perceived risks while also providing symptom relief. Participants desired evidence-based information about mode safety to better inform mode selection during pregnancy.

CONCLUSIONS

A range of personal and social factors influenced mode preferences during pregnancy. Many participants desired to reduce harms and use cannabis more safely in pregnancy but received little mode-specific information to guide these preferences. Further research identifying mode-specific risks is needed to guide harm reduction approaches during pregnancy.

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.

Tobacco and Cannabis Use During and After Pregnancy in California

OBJECTIVES

As the social and legal acceptance of cannabis use grows, health professionals must understand and mitigate the impact of cannabis use in the perinatal period. Here we compare the prevalence of tobacco and cannabis use during and after pregnancy in California, a state that recently legalized cannabis use.

METHODS

Measures of tobacco and cannabis use during and after pregnancy were obtained from California's Maternal and Infant Health Assessment, an annual population-based survey of California resident women with a live birth. To allow analysis of county-level variation, we pooled data from the 35 counties with the largest numbers of births from 2017 to 2019.

RESULTS

Cannabis use was more than twice as common as cigarette smoking among pregnant women (4.9% vs. 2.1%) in California. This difference was even more pronounced in some counties; for example, in Los Angeles, cannabis use was four times more prevalent than cigarette use. Either during or soon after birth, 7.3% of women in California reported cannabis use. Of those who smoked tobacco cigarettes prior to pregnancy, 73% quit before their third trimester of pregnancy, though 33.0% of these women reported a post-partum relapse in cigarette use.

CONCLUSIONS

States that have legalized cannabis must attend to the increasing prevalence of perinatal cannabis use, as well as concurrent use with tobacco and other substances. Efforts to support cannabis cessation should draw from successful public health approaches in tobacco control.

"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.

Impact of Tobacco and Marijuana on Infertility and Early Reproductive Wastage

Reducing exposure to tobacco and marijuana during preconception and early pregnancy is a critical area of intervention for obstetricians, gynecologists, and other reproductive health care professionals. Beyond the deleterious personal health effects, both substances have been extensively associated with short-term and long-term detrimental effects to gametogenesis, fecundity, as well as tissue level effects in the reproductive tracts. When tobacco and marijuana do not impair the ability to achieve pregnancy, an increasing body of literature suggests either may be associated with increased risk of early pregnancy loss and reproductive wastage. In this review, we will discuss what is known about how tobacco and marijuana affect the male and female reproductive systems and highlight how these consequences may impair attempts at successful conception and pregnancy continuation beyond the first trimester.
