Abstract
The aim of this study is to determine factors associated with cannabis discontinuation, to assess the impact of mental health and addiction interventions on cannabis discontinuation during pregnancy and to investigate the neonatal impact of cannabis discontinuation. This is a 10-year cohort study in a tertiary hospital in Barcelona, Spain, including women with self-reported cannabis use during pregnancy. Main outcome was cannabis discontinuation based on biological sample testing. Secondary outcomes were neonatal intensive care unit (NICU) admission, preterm birth, birth weight and bottle-feeding. When cannabis use was detected during pregnancy, 32 out of 81 (38.3%) discontinued cannabis during pregnancy vs. four out of 61 (6.6%) when detected at birth (p < .001). Multivariate binary logistic regression showed that null parity (OR: 6.95, p = .011), detection of cannabis use during pregnancy (OR: 5.35, p = .018) and early detection and referral to mental health care for counseling on cannabis cessation and interventions on the first trimester (OR: 25.46, p < .001) increased cannabis discontinuation. Risk for preterm birth <37 weeks (11.4% vs. 30.8%) and NICU admission (25.7% vs. 54.2%) were lower when discontinuation. Early detection of cannabis use during pregnancy, cessation counseling with mental health interventions, and null parity are predictors for cannabis discontinuation during pregnancy.

Changes in online marketing and sales practices among non-medical cannabis retailers in 5 US cities, 2022 to 2023. Prev Med Rep 2024; 42:102755. [PMID: 38764758 PMCID: PMC11101894 DOI: 10.1016/j.pmedr.2024.102755] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 04/10/2024] [Accepted: 05/07/2024] [Indexed: 05/21/2024] Open
Abstract
Objectives Given the evolving cannabis marketplace (e.g., products, marketing strategies), this study examined online cannabis marketing practices over time. Methods In 2022 and 2023, researchers assessed website content (e.g., age verification, sales, delivery, warnings, ad content, promotional strategies) among 175 randomly-selected cannabis retailers' websites across 5 US cities (Denver, Colorado; Seattle, Washington; Portland, Oregon; Las Vegas, Nevada; Los Angeles [LA], California, n=∼35/city). Analyses compared data from 2022 vs. 2023 and considered regulatory factors across cities. Results Similar to 2022, in 2023, 76.6 % required age verification for site entry, 85.1 % used social media promotion, and 90.9 % offered online sales (82.4 % of which required age verification and 34.6 % offered delivery). There were significant (p < .05) decreases from 2022 to 2023 in the proportions indicating medical card requirements (27.4 % to 15.4 %), purchase limits (59.4 % to 47.4 %), health warnings (38.9 % to 29.7 %), health benefits (60 % to 47.4 %), and discounts/price promotions (92.6 % to 86.3 %). In 2023, proportions differed across cities in ways reflecting whether state/local law allowed online sales (>90 % in Denver, Las Vegas, LA), allowed discounts/price promotions (100 % in Denver and Las Vegas), or required health warnings (48-60 % in Seattle and LA vs. < 20 % elsewhere). Despite all sites prohibiting youth-oriented content and all but Denver and Las Vegas prohibiting health claims, 30.3 % posted content targeting youth/young adults (LA = 8.1 % to Denver = 74.2 %) and 47.4 % health claims (Seattle = 27.0 % to Denver = 71.0 %). Conclusions Online cannabis retail presents risks for access and appeal to minors, emphasizes health benefits, and uses price promotions, regardless of restrictions, indicating need for greater regulatory efforts.

Abstract
The increasing prevalence of cannabis use during pregnancy has raised significant medical concerns, primarily related to the presence of Δ9-tetrahydrocannabinol (THC), which readily crosses the placenta and impacts fetal brain development. Previous research has identified midbrain dopaminergic neuronal alterations related to maternal THC consumption. However, the enduring consequences that prenatal cannabis exposure (PCE) has on striatum-based processing during voluntary reward pursuit have not been specifically determined. Here, we characterize PCE rats during food (palatable pellets) or opioid (remifentanyl)-maintained reward seeking. We find that the supra motivational phenotype of PCE rats is independent of value-based processing and is instead related to augmented reinforcing efficiency of opioid rewards. Our findings reveal that in utero THC exposure leads to increased cue-evoked dopamine release responses and an overrepresentation of cue-aligned, effort-driven striatal patterns of encoding. Recapitulating findings in humans, drug-related neurobiological adaptations of PCE were more pronounced in males, who similarly showed increased vulnerability for relapse. Collectively, these findings indicate that prenatal THC exposure in male rats engenders a pronounced neurodevelopmental susceptibility to addiction-like disorders later in life.

Abstract
OBJECTIVE This study aimed to estimate the proportion of perinatal women reporting a health care worker (HCW) discussed cannabis use during pregnancy or breastfeeding with them and to evaluate the association between HCWs' discussions and perinatal cannabis use and cannabis use while breastfeeding. STUDY DESIGN Data from Health eMoms (a longitudinal, state-representative survey of Colorado mothers, collected from 2018 to 2020 [n = 3,193]) were utilized in logistic regressions assessing the relationship between HCW discussions about cannabis and perinatal cannabis use and cannabis use while breastfeeding at two time points postpartum, adjusting for sociodemographic factors. RESULTS A total of 5.8% of the sample reported cannabis use either during their most recent pregnancy or while breastfeeding at 3 to 6 months' postpartum. A total of 67.8% of the sample reported an HCW-discussed cannabis at prenatal visits. Women reporting perinatal use were more likely to report HCW discussing cannabis compared with nonusers (82.2 vs. 65.3%, p < 0.01). There was not a significant association between HCW discussions and cannabis use while breastfeeding at either time point postpartum. Compared with nonusers, women using perinatally were more likely to report cannabis Web sites (28.9 vs. 6.5%), cannabis stores (15.7 vs. 3.8%), or word-of-mouth (28.4 vs. 17.1%) as trusted sources of cannabis-related information. CONCLUSION HCW discussions about cannabis use during pregnancy or breastfeeding are not universally reported. This study highlights the need for further encouragement of universal HCW discussions of cannabis use during pregnancy and breastfeeding, strengthening of messaging around cannabis use during these periods, and improved delivery of reliable cannabis-related health information to this population. KEY POINTS · HCW discussions of perinatal cannabis use are not universally reported by women.. · Women reporting perinatal use were more likely to report HCW discussions of cannabis.. · Women reporting perinatal cannabis use were more likely to trust word-of-mouth or cannabis stores or Web sites..

Abstract
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.

Maternal Cannabis Use during Lactation and Potential Effects on Human Milk Composition and Production: A Narrative Review. Adv Nutr 2024; 15:100196.

Abstract
Cannabis use has increased sharply in the last 20 y among adults, including reproductive-aged women. Its recent widespread legalization is associated with a decrease in risk perception of cannabis use during breastfeeding. However, the effect of cannabis use (if any) on milk production and milk composition is not known. This narrative review summarizes current knowledge related to maternal cannabis use during breastfeeding and provides an overview of possible pathways whereby cannabis might affect milk composition and production. Several studies have demonstrated that cannabinoids and their metabolites are detectable in human milk produced by mothers who use cannabis. Due to their physicochemical properties, cannabinoids are stored in adipose tissue, can easily reach the mammary gland, and can be secreted in milk. Moreover, cannabinoid receptors are present in adipocytes and mammary epithelial cells. The activation of these receptors directly modulates fatty acid metabolism, potentially causing changes in milk fatty acid profiles. Additionally, the endocannabinoid system is intimately connected to the endocrine system. As such, it is probable that interactions of exogenous cannabinoids with the endocannabinoid system might modify release of critical hormones (e.g., prolactin and dopamine) that regulate milk production and secretion. Nonetheless, few studies have investigated effects of cannabis use (including on milk production and composition) in lactating women. Additional research utilizing robust methodologies are needed to elucidate whether and how cannabis use affects human milk production and composition.

Abstract
BACKGROUND 4-20% of people report using cannabis during pregnancy, thereby it is essential to assess the associated risks. There is some evidence that prenatal cannabis exposure (PCE) may be associated with increased risk for developing of obesity and diabetes later in life, however this has not been well explored under controlled conditions. The aim of this study was to use a translational THC vapor model in rodents to characterize the effects of PCE on adiposity, glucose metabolism, and feeding patterns in adulthood, with focus on potential sex differences. METHODS Pregnant Sprague Dawley rats were exposed to vaporized THC (100 mg/ml) or control (polyethylene glycol vehicle) across the entire gestational period. Adult offspring from PCE (n = 24) or control (n = 24) litters were subjected to measures of adiposity, glucose metabolism and feeding behavior. Rats were then placed onto special diets (60% high-fat diet [HFD] or control 10% low fat diet [LFD]) for 4-months, then re-subjected to adiposity, glucose metabolism and feeding behavior measurements. RESULTS PCE did not influence maternal weight or food consumption but was associated with transient decreased pup weight. PCE did not initially influence bodyweight or adiposity, but PCE did significantly reduce the rate of bodyweight gain when on HFD/LFD, regardless of which diet. Further, PCE had complex effects on glucose metabolism and feeding behavior that were both sex and diet dependent. No effects of PCE were found on plasma leptin or insulin, or white adipose tissue mass. CONCLUSIONS PCE may not promote obesity development but may increase risk for diabetes and abnormal eating habits under certain biological and environmental conditions. Overall, this data enhances current understanding of the potential impacts of PCE.

Abstract
AIMS Preclinical studies have found that chronic ∆9-tetrahydrocannabinol (THC) treatment is directly associated with weight gain when introduced during adolescence and adulthood, but the effect of prenatal THC is unclear. Clinical studies have demonstrated prenatal exposure to THC is a prospective predictor of increased health risks associated with obesity. Our study aims to examine prenatal THC impact on obesity risks in males and females throughout adolescence using a clinically relevant inhalation model. METHODS Pregnant rats were exposed to one of the following from gestational day 2 through birth: 10 mg THC, 40 mg THC, or air. Daily 10-min inhalations were conducted in each animal from 0900 to 1200. Offspring from each treatment group were given either a high-fat diet (HFD) or a normal diet (ND). Food and bodyweights were collected daily, while circadian activity, locomotion, and exercise were measured periodically (PND 21-60). Pregnancy weight gain and birth weight were collected to determine early-life developmental effects. RESULTS Rats prenatally treated with low-dose THC (LDTHC) generally had lower dark-cycle activity compared with control counterparts, but this altered activity was not observed at the higher dose of THC (HDTHC). In terms of open-field activity, THC doses displayed a general increase in locomotion. In addition, the LDTHC male rats in the ND showed significantly greater exploratory behavior. Prenatal THC had dose-dependent effects on maternal weight gain and birth weight. CONCLUSIONS Overall, our findings indicate there are some activity-related and developmental effects of prenatal THC, which may be related to obesity risks later in life.

Abstract
Over the past two decades, cannabis policies have liberalized in the United States, culminating in the legalization of recreational cannabis in Colorado and Washington state in 2012. This review will focus on the impact of recreational cannabis legalization in Colorado. While the prevalence of past-year and past-month cannabis use has remained relatively steady among adolescents post-legalization, the prevalence of young adult use has continued to rise. Cannabis products with increased potency have become more prevalent and widely used. There are concerns that the use of products with increased potency will increase risk for cannabis use and comorbid mental health disorders, particularly cannabis-induced psychosis and suicidal behavior, although more research is needed to fully understand the impact of high-potency products. Since the legalization of recreational cannabis, numerous additional public health concerns have emerged: unintentional overdoses requiring acute care visits, electronic vaping-associated lung injury, increased motor vehicle collisions related to cannabis consumption, and higher rates of cannabis use during pregnancy. Lessons learned from the first decade of cannabis legalization emphasize the need for research efforts to provide evidence-based guidelines, inform prevention strategies, and implement selective interventions for at-risk populations including youth, individuals with comorbid mental health disorders, and individuals who are pregnant.

Abstract
Perinatal mental health is recognized as a priority component of obstetrical care. Perinatal patients often turn to their obstetrician for help with mental health concerns as they view them as their primary health care provider. Unfortunately, obstetricians face challenges in providing adequate support due to time constraints and limited expertise. Integrated behavioral health care offers a collaborative and cost-effective solution to enhance patient care and clinician satisfaction. Integrated behavioral health clinicians possess fundamental skills to care for patients throughout the reproductive lifespan and assist obstetricians in identifying and managing common mood concerns.

Torres J, Miller C, Apostol M, Gross J, Maxwell JR. The impact of recreational cannabinoid legalization on utilization in a pregnant population. Front Public Health 2024; 12:1278834. [PMID: 38444440 PMCID: PMC10912290 DOI: 10.3389/fpubh.2024.1278834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 02/02/2024] [Indexed: 03/07/2024] Open
Abstract
Background Marijuana potency and utilization both continue to increase across the United States. While the overall prevalence of cannabinoid utilization during pregnancy has been surveyed in various studies, the direct impact of changing governmental policies on pregnancy use is less characterized. Thus, we aimed to investigate how the legalization of recreational cannabinoid products impacted use during pregnancy in the state of New Mexico. Methods Participants who had a live birth during two study epochs were included: pre-legalization (Epoch 1: 1 January 2019-31 March 2021) and post-legalization (Epoch 2: 1 November 2021-30 November 2022). Participants were further divided into case group [prenatal cannabinoid exposure (PCE)] vs. control (no PCE), with cases being identified by documented self-report or a positive laboratory toxicology test for cannabinoid use during pregnancy. Results A total of 1,191 maternal/infant dyads were included in Epoch 1, and 378 maternal/infant dyads were included in Epoch 2. In Epoch 1, 788 dyads were controls with 403 cases, while Epoch 2 had 292 controls and 86 cases. Interestingly there was a significant decrease in self-report or positive laboratory toxicology tests in Epoch 2 compared to Epoch 1. Infants born following PCE in both Epoch groups were more commonly born via Cesarean section, had significantly smaller birth weight, length, and head circumference as well as significantly lower Apgar scores at 1 and 5 min. Conclusion The finding of decreased reported cannabinoid use in the post-legalization group is contradictory to previous studies which have shown increased rates of cannabinoid use after legalization. This could be due to multiple factors including changes in screening practices, the COVID-19 pandemic, and lack of commercialization of THC products. Additional studies are needed to further characterize how changing governmental policies impacts utilization during pregnancy.

Abstract
Introduction: Cannabis is increasingly being consumed by pregnant women for recreational purposes as well as for its antiemetic and anxiolytic effects despite limited studies on its safety during pregnancy. Importantly, phytocannabinoids found in cannabis can pass through the placenta and enter the fetal circulation. Recent reports suggest gestational cannabis use is associated with negative fetal outcomes, including fetal growth restriction and perinatal intensive care, however, the effects of delta-9-tetrahydrocannabinol (THC) on fetal heart development remains to be elucidated. Materials and Methods: We aimed to determine the outcomes of maternal THC exposure on fetal heart development in mice by administering 0, 5, or 10 mg/kg/day of THC orally to C57BL/6 dams starting at embryonic day (E)3.5. Offspring were collected at E12.5 for molecular analysis, at E17.5 to analyze cardiac morphology or at postnatal day (PND)21 to assess heart function. Results: Maternal THC exposure in E17.5 fetuses resulted in an array of cardiac abnormalities with an incidence of 44% and 55% in the 5 and 10 mg/kg treatment groups, respectively. Maternal THC exposure in offspring resulted in ventricular septal defect, higher semilunar valve volume relative to orifice ratio, and higher myocardial wall thickness. Notably, cell proliferation within the ventricular myocardium was increased, and expression of multiple cardiac transcription factors was downregulated in THC-exposed E12.5 fetuses. Furthermore, heart function was compromised with lower left ventricular ejection fraction, fractional shortening, and cardiac output in PND21 pups exposed to THC compared to controls. Discussion: The results show that maternal THC exposure during gestation induces myocardial hyperplasia and semilunar valve thickening in the fetal heart and postnatal cardiac dysfunction. Our study suggests that maternal cannabis consumption may induce abnormalities in the developing heart and cardiac dysfunction in postnatal life.

Cannabis Retailer Communication About Cannabis Products, Health Benefits, and Risks: A Mystery Shopper Study of Licensed Retailers in Five U.S. Cities. J Stud Alcohol Drugs 2024; 85:100-108. [PMID: 37917012 PMCID: PMC10846606 DOI: 10.15288/jsad.23-00034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Accepted: 07/09/2023] [Indexed: 11/03/2023] Open
Abstract
OBJECTIVE As the U.S. cannabis market expands, surveillance of retailer practices, especially product health claims and risks, is crucial to protect consumers. In this study, mystery shoppers (i.e., staff not explicitly identified as researchers) examined retail personnel communication regarding product recommendations, health benefits, safety, and/or risks among U.S. cannabis retailers. METHOD In Summer 2022, mystery shoppers audited 140 licensed cannabis retailers in 5 cities in states with established nonmedical (i.e., recreational) cannabis sales and diverse regulations (Denver, Colorado; Seattle, Washington; Portland, Oregon; Las Vegas, Nevada; Los Angeles, California). Descriptive and bivariate analyses characterized retail personnel communication overall and across cities. RESULTS Common product recommendations for new users included edibles, pre-rolled joints, and bud/flower, and 8.6% offered free/inexpensive ways to sample products. Although Colorado, Washington, and Oregon explicitly prohibited health claims in advertising or labels, more than 90% of retailers there endorsed use for anxiety, insomnia, and/or pain. Whereas 54.3% endorsed use for pregnancy-related nausea (least common in Denver, 23.3%; most common in Seattle, 76.7%), 26.4% warned against use during pregnancy (most frequently in Denver, 46.7%; least frequently in Seattle and Portland, 13.3%). Overall, 52.1% warned against driving after use (most frequently in Denver, 80.0%; least frequently in Las Vegas, 20.0%). Almost all (≥90%) sold cannabidiol (CBD) products and endorsed their health benefits and safety, but few (<10%) sold or endorsed delta-8 tetrahydrocannabinol (THC), etc. (all of which were in Los Angeles). CONCLUSIONS Ongoing cannabis retail surveillance, particularly using protocols assessing factors outside those visibly observable, is needed to inform regulatory and enforcement efforts, especially related to health claims.

Abstract
Because of substantial limitations in available national data, such as inconsistencies among surveys and small sample sizes, the increased prevalence of cannabis use among adolescents since recreational legalization has not been directly observed. Nevertheless, both usage frequency and product potency have significantly increased, alongside alternative routes of delivery to smoking, such as vaping cannabis. Moreover, certain populations may be especially vulnerable to the effects of legalization. Regardless of differing state-level cannabis legalization status, the adverse consequences of cannabis on youth have clear negative impacts on mental health, medical symptoms, educational outcomes, and increased risk of addiction to other substances.

[PMID: 37778699 PMCID: PMC10841490 DOI: 10.1016/j.ajogmf.2023.101171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 09/21/2023] [Accepted: 09/25/2023] [Indexed: 10/03/2023]
Abstract
BACKGROUND Nausea and vomiting of pregnancy, also referred to as morning sickness, affects more than 70% of all pregnancies. Symptoms range from mild to severe and, in some cases, can be debilitating, resulting in a reduced quality of life. Moreover, prenatal cannabis use prevalence has doubled in the United States, and cannabis potency, measured by the concentration of delta-9-tetrahydrocannabiniol, has increased from 10% in 2009 to 14% in 2019. State-level recreational legalization of cannabis may contribute to the liberalization of its use and reduced risk perception. Furthermore, the relatively recent discovery of cannabinoid hyperemesis syndrome may contribute to the mischaracterization of morning sickness in individuals who use cannabis during pregnancy. Although cannabis has well-documented antiemetic properties, there is insufficient research on the topic. Therefore, it is essential to establish a tangible understanding of the association between nausea and vomiting of pregnancy and prenatal cannabis use. OBJECTIVE This study aimed to estimate the degree to which nausea and vomiting of pregnancy might be associated with prenatal cannabis use in a sample of pregnant people in Michigan, a state where recreational cannabis use became legal in December 2018. STUDY DESIGN This was a prospective study of participants from the Michigan Archive for Research on Child Health, a population-based pregnancy cohort that was recruited using a probability-based sampling approach. Participants were recruited from 22 prenatal clinics located throughout Michigan's lower peninsula. Cross-sectional analyses were performed for data available between October 2017 and January 2022. RESULTS Among this sample of Michigan pregnant people, 14% (95% confidence interval, 11%-16%) reported cannabis use. Participants who experienced increasing morning sickness severity had higher odds of using cannabis (adjust odds ratio, 1.2; 95% confidence interval, 1.1-1.2). When the sample was restricted to first-trimester morning sickness and cannabis use, the results remained statistically robust. When the direction of the association was reversed, an increase in morning sickness severity was detected among participants who used cannabis during pregnancy (ßadjusted, 0.2; 95% confidence interval, 0.1-0.2). Lastly, the association between prepregnancy cannabis use and first-trimester morning sickness was investigated. Study findings suggest an increase in morning sickness severity among people who used cannabis in the 3 months before pregnancy compared with those who did not use cannabis (ßadjusted, 0.1; 95% confidence interval, 0.003-0.200). CONCLUSION Study findings indicated a link between nausea and vomiting of pregnancy and prenatal cannabis use. Moreover, this study revealed that using cannabis in the 3 months before pregnancy is associated with first-trimester morning sickness severity. The strengths of our study contribute to the scant epidemiologic evidence in this area of research. More fine-grained, time-specific data on nausea and vomiting of pregnancy and prenatal cannabis use are necessary to draw inferences about cause-effect relationships. Our study might provide a basis to discourage cannabis use during pregnancy until more evidence is collected.

Abstract
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.

Cannabis retailer marketing strategies and regulatory compliance: A surveillance study of retailers in 5 US cities. Addict Behav 2023; 143:107696. [PMID: 36966547 PMCID: PMC10674052 DOI: 10.1016/j.addbeh.2023.107696] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 02/24/2023] [Accepted: 03/14/2023] [Indexed: 03/19/2023]
Abstract
As cannabis retail expands in the US, its surveillance is crucial to inform regulations and protect consumers. This study addresses this need by conducting point-of-sale audits examining regulatory compliance (e.g., age verification, signage), advertising/promotional strategies, products, and pricing among 150 randomly-selected cannabis retailers in 5 US cities (30/city: Denver, Colorado; Seattle, Washington; Portland, Oregon; Las Vegas, Nevada; Los Angeles, California) in Summer 2022. Descriptive and bivariate analyses characterized the retailers overall and across cities. Age verification rates were high (>90%). The majority of retailers had signage indicating restricted access (e.g., no minors; 87.3%), onsite consumption (73.3%), and distribution to minors (53.3%). Retailers were likely to post warnings regarding use during pregnancy/breastfeeding (72.0%), followed by health risks (38.0%), impacts on children/youth (18.7%), and DUI (14.0%). Overall, 28.7% posted health claims, 20.7% posted youth-oriented signage, and 18.0% had youth-oriented packaging. Price promotions were prevalent, particularly price specials (75.3%), daily/weekly/monthly specials (66.7%), and membership programs (39.3%). One-fourth had signs/promotions indicating curbside delivery/pick-up (28.0%) and/or online ordering (25.3%); 64.7% promoted their website or social media page. The most potent cannabis products were most often e-liquids (38.0%) or oils (24.7%); the least potent were often edibles (53.0%). The most expensive product was often bud/flower (58.0%); the least was joints (54.0%). The vast majority (≥81%) sold vaporizers, wrapping papers, and hookah/waterpipes/bongs, and 22.6% sold CBD products. Marketing strategies differed across cities, reflecting differences in state-specific regulations and/or gaps in compliance/enforcement. Findings underscore the need for ongoing cannabis retail surveillance to inform future regulatory and enforcement efforts.

Abstract
BACKGROUND With the growing availability of cannabis and the popularization of additional routes of cannabis use beyond smoking, including edibles, the prevalence of cannabis use in pregnancy is rapidly increasing. However, the potential effects of prenatal cannabis use on fetal developmental programming remain unknown. RESULTS We designed this study to determine whether the use of edible cannabis during pregnancy is deleterious to the fetal and placental epigenome. Pregnant rhesus macaques consumed a daily edible containing either delta-9-tetrahydrocannabinol (THC) (2.5 mg/7 kg/day) or placebo. DNA methylation was measured in 5 tissues collected at cesarean delivery (placenta, lung, cerebellum, prefrontal cortex, and right ventricle of the heart) using the Illumina MethylationEPIC platform and filtering for probes previously validated in rhesus macaque. In utero exposure to THC was associated with differential methylation at 581 CpGs, with 573 (98%) identified in placenta. Loci differentially methylated with THC were enriched for candidate autism spectrum disorder (ASD) genes from the Simons Foundation Autism Research Initiative (SFARI) database in all tissues. The placenta demonstrated greatest SFARI gene enrichment, including genes differentially methylated in placentas from a prospective ASD study. CONCLUSIONS Overall, our findings reveal that prenatal THC exposure alters placental and fetal DNA methylation at genes involved in neurobehavioral development that may influence longer-term offspring outcomes. The data from this study add to the limited existing literature to help guide patient counseling and public health polices focused on prenatal cannabis use in the future.

Abstract
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.

Abstract
Numerous drugs ingested during pregnancy can impact the developing fetus. Although some effects are apparent at birth as overt teratogenicity or profound neonatal withdrawal, others become apparent only after a careful long-term follow-up into childhood. Shifting legal and cultural attitudes toward marijuana have led to increased use during pregnancy. This shift should prompt health care providers to carefully consider the drug's mechanism of action, its interaction with the placenta, and the potential consequences of fetal exposure. The primary psychoactive compound in marijuana is Δ9-tetrahydrocannabinol (THC), which agonizes endogenous cannabinoid receptors. Cannabinoid receptors are present in the fetal brain early in gestation and appear to have an important role in the developing central nervous system. THC crosses the placenta in sufficient quantities to raise concerns about exogenous exposure during fetal development. Robust follow-up studies suggest that marijuana use during pregnancy contributes to suboptimal fetal growth. At school age, heavy prenatal marijuana exposure predicts challenges in executive function (specifically, memory and reasoning) and externalizing behavior (e.g., hyperactivity and inattention). Memory and behavioral problems persist into early adulthood. These challenges coincide with a higher risk of heavy marijuana use in offspring. In concert with a suboptimal environment, young adults may experience a higher risk of global cognitive impairment and/or delinquency. Importantly, these adverse outcomes appear to be mitigated by postnatal factors including home environment. Ongoing studies in the modern era will be vital to enhance our understanding of the mechanisms by which THC impacts the fetus and confirm or refute knowledge regarding long-term impact. This knowledge will inform both health care providers and parents in collaborative decision-making to optimize the outcome of children.

Abstract
BACKGROUND Cannabis use and cannabis use disorder (CUD) are associated with mental health disorders, however the extent of this matter among pregnant and recently postpartum (e.g., new moms) women in the US is unknown. Associations between cannabis use, DSM-5 CUD and DSM-5 mental health disorders (mood, anxiety, personality and post-traumatic stress disorders) were examined among a nationally representative sample of pregnant and postpartum women. METHODS The 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III was used to examine associations between past-year cannabis use, CUD and mental health disorders. Weighted logistic regression models were used to estimate unadjusted and adjusted odds ratios (aORs). The sample (N=1316) included 414 pregnant and 902 postpartum women (pregnant in the past year), aged 18-44 years old. RESULTS The prevalence of past-year cannabis use and CUD was 9.8% and 3.2%, respectively. The odds of cannabis use (aORs range 2.10-3.87, p-values<0.01) and CUD (aORs range 2.55-10.44, p-values< 0.01) were higher among women with versus without any past-year mood, anxiety or posttraumatic stress disorders or any lifetime personality disorder. aORs for the association of cannabis use with specific mood, anxiety or personality disorders ranged from 1.95 to 6.00 (p-values<0.05). aORs for the association of CUD with specific mood, anxiety or personality disorders ranged from 2.36 to 11.60 (p-values<0.05). CONCLUSIONS From pregnancy up to one year postpartum is a critical period where women may be particularly vulnerable to mental health disorders, cannabis use and CUD. Treatment and prevention are essential.

Abstract
BACKGROUND Cannabis use during pregnancy is increasing, with 19-22% of patients testing positive at delivery in Colorado and California. Patients report using cannabis to alleviate their nausea and vomiting, anxiety, and pain. However, preclinical and clinical data highlight harmful effects to offspring physiology and behavior following fetal cannabis exposure. This narrative review identifies potential areas for intervention to decrease cannabis consumption during pregnancy. METHODS A combination of keywords, including "cannabis", "cannabis", "weed", "pregnancy", "morning sickness", "child protective services", and "budtender" were searched in databases such as PubMed and Google Scholar, as well as in social media forums, governmental webpages, and other publicly available sources. RESULTS The literature search identified several areas for intervention to reduce cannabis use during pregnancy, including physician and pharmacist training, engagement with pregnant patients, regulation of dispensary workers, and the role of child protective services. DISCUSSION This comprehensive review identifies multiple areas for improvement to benefit pregnant patients. Recommendations are independent and can be implemented simultaneously by the identified groups. Limitations of this research includes the relatively limited availability of data focused specifically on cannabis consumption during pregnancy and the complexity of the sociopolitical field of substance use during pregnancy. CONCLUSIONS Cannabis consumption during pregnancy is increasing and causes harm to the developing fetus. To educate pregnant patients about these risks, we must address the gaps in education from multiple contact points.

Abstract
Objective To examine whether timing of in utero marijuana exposure independently and negatively impacts fetal growth, and if these effects are global or specific to certain growth parameters. Study design The two study groups were marijuana users (N = 109) and a randomly selected control group of biochemically verified non-users (n = 171). Study data were obtained via manual abstraction of electronic medical records. Results After control for significant confounders, regression results indicated significant (p < .05) decrease in newborn weight following first trimester marijuana exposure only (-154 g) and following marijuana exposure throughout gestation (-185 g) compared to controls. There were also significant deficits in head circumference following marijuana exposure in the first and second trimester only (-.83 cm) and marijuana exposure throughout pregnancy (-.79 cm) compared to controls. Newborn length was not significantly predicted by marijuana exposure. Conclusions Timing of marijuana exposure appears to play a key role in specific fetal growth deficits, with exposure throughout gestation most detrimental. However even first trimester exposure may result in decreased weight. Timing and amount of use could be confounded in this study as those who quit early in pregnancy may have been lighter users than those who continued throughout pregnancy. More research is clearly needed to better understand the role of amount and timing of in utero marijuana exposure in predicting different aspects of fetal growth, however, this study suggests that women should be encouraged to avoid marijuana use at any point in pregnancy.

Abstract
Cannabis use during pregnancy is increasing. The improvement of pregnancy-related symptoms including morning sickness and management of mood and stress are among the most reported reasons for its use. Δ9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD) are the most abundant cannabinoids found within the cannabis flower. The concentration of these components has drastically increased in the past 20 years. Additionally, many edibles contain only one cannabinoid and are marketed to achieve a specific goal, meaning there are an increasing number of pregnancies that are exposed to isolated cannabinoids. Both Δ9-THC and CBD cross the placenta and can impact the fetus directly, but the receptors through which cannabinoids act are also expressed throughout the placenta, suggesting that the effects of in-utero cannabinoid exposure may include indirect effects from the placenta. In-utero cannabis research focuses on short and long-term fetal health and development; however, these studies include little to no placenta analysis. Prenatal cannabinoid exposure is linked to small for gestational age and fetal growth-restricted babies. Compromised placental development is also associated with fetal growth restriction and the few studies (clinical and animal models) that included placental analysis, identify changes in placental vasculature and function in these cannabinoid-exposed pregnancies. In vitro studies further support cannabinoid impact on cell function in the different populations that comprise the placenta. In this article, we aim to summarize how phytocannabinoids can impact placental development and function. Specifically, the cannabinoids and their actions at the different receptors are described, with receptor localization throughout the human and murine placenta discussed. Findings from studies that included placental analysis and how cannabinoid signaling may modulate critical developmental processing including cell proliferation, angiogenesis and migration are described. Considering the current research, prenatal cannabinoid exposure may significantly impact placental development, and, as such, identifying windows of placental vulnerability for each cannabinoid will be critical to elucidate the etiology of fetal outcome studies.

Abstract
Public perception surrounding whether cannabis use is harmful during pregnancy often diverges greatly from the recommendations of doctors and healthcare providers. In contrast to the medical guidance of abstinence before, during, and after pregnancy, many women of reproductive age believe cannabis use during pregnancy is associated with little potential harm. Legalization and social cues support public perceptions that cannabis use during pregnancy is safe. Moreover, pregnant women may consider cannabis to be a safe alternative for treating pregnancy related ailments, including morning sickness. Compounding the problem is a lack of medical and federal guidance on safe, low, or high-risk levels of cannabis use. These issues mirror the continuing debate surrounding alcohol use and health, in particular, whether there are safe or lower risk levels of alcohol consumption during pregnancy. Clinical studies to date suffer from several limitations. First, most human studies are correlative in nature, meaning that causal associations cannot be made between in utero cannabis exposure and health and behavioral outcomes later in life. Due to obvious ethical constraints, it is not possible to randomly assign pregnant mothers to cannabis or other drug exposure conditions-a requirement needed to establish causality. In addition, clinical studies often lack quantitative information on maternal exposure (i.e., dose, frequency, and duration), include a small number of individuals, lack replication of outcome measures across cohorts, rely on self-report to establish maternal drug use, and suffer from unmeasured or residual confounding factors. Causal associations between maternal cannabis exposure and offspring outcomes are possible in preclinical cohorts but there is a large amount of heterogeneity across study designs and developmental differences between rodents and humans may limit translatability. In this review, we summarize research from human and preclinical models to provide insight into potential risks associated with prenatal cannabinoid exposure (PCE). Finally, we highlight gaps in knowledge likely to contribute to the growing divide between medical guidance and public attitudes regarding cannabis use during pregnancy.

Abstract
Exposure to substances of abuse during pregnancy can have long-lasting effects on offspring. Alcohol is one of the most widely used substances of abuse that leads to the most severe consequences. Recent studies in the United States, Canada, and the United Kingdom showed that between 1% and 7% of all children exhibit signs and symptoms of fetal alcohol spectrum disorder (FASD). Despite preventive campaigns, the rate of children with FASD has not decreased during recent decades. Alcohol consumption often accompanies exposure to such drugs as tobacco, cocaine, opioids, and cannabis. These interactions can be synergistic and exacerbate the deleterious consequences of developmental alcohol exposure. The present review focuses on interactions between alcohol and cannabis exposure and the potential consequences of these interactions.

Abstract
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.

Abstract
As recreational and medical cannabis use increases in the U.S., the proliferation of novel cannabis products is expected to continue. Understanding cannabis product preferences and use patterns may inform public health and policy decisions. This study investigated similarities and differences in cannabis use patterns, product preferences, and beliefs about cannabis' subjective effects and therapeutic benefits among individuals with and without a medical cannabis card (MCC). Participants with an MCC completed individual interviews (N = 25; 40% male). Participants without an MCC completed focus groups (N = 31; 6-7 participants/group; 72% male). All sessions followed a semistructured agenda. Participants were queried about their use routines, reasons for using cannabis, and perceptions and experiences of subjective cannabis effects. Thematic analysis of coded transcripts revealed that MCC participants had structured, daily cannabis use routines whereas non-MCC participants' use routines were less structured. Product information including strain and cannabinoid composition were important to MCC participants whereas non-MCC participants primarily evaluated quality based on perceptual (e.g., olfactory) cues. Regardless of MCC status, participants reported misconceptions about cannabis' therapeutic benefits and agreed that the two primary cannabis strains-Indica and Sativa-produced primarily sedative and stimulant effects, respectively. Results have clinical, public health, and policy implications surrounding cannabis recommendation guidelines and ways providers can relay accurate information to patients seeking medical cannabis. Future research assessing demographic and geographic differences in cannabis product preferences and beliefs about medical cannabis use is warranted. Further, quantitative research is needed to evaluate whether cannabis' therapeutic value differs across products. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Abstract
Sociocultural attitudes towards cannabis legalization contribute to the common misconception that it is a relatively safe drug and its use during pregnancy poses no risk to the fetus. However, longitudinal studies demonstrate that maternal cannabis exposure results in adverse outcomes in the offspring, with a heightened risk for developing psychopathology. One of the most reported psychiatric outcomes is the proneness to psychotic-like experiences during childhood. How exposure to cannabis during gestation increases psychosis susceptibility in children and adolescents remains elusive. Preclinical research has indicated that in utero exposure to the major psychoactive component of cannabis, delta-9-tetrahydrocannabinol (THC), deranges brain developmental trajectories towards vulnerable psychotic-like endophenotypes later in life. Here, we present how prenatal THC exposure (PCE) deregulates mesolimbic dopamine development predisposing the offspring to schizophrenia-relevant phenotypes, exclusively when exposed to environmental challenges, such as stress or THC. Detrimental effects of PCE are sex-specific because female offspring do not display psychotic-like outcomes upon exposure to these challenges. Moreover, we present how pregnenolone, a neurosteroid that showed beneficial properties on the effects elicited by cannabis intoxication, normalizes mesolimbic dopamine function and rescues psychotic-like phenotypes. We, therefore, suggest this neurosteroid as a safe "disease-modifying" aid to prevent the onset of psychoses in vulnerable individuals. Our findings corroborate clinical evidence and highlight the relevance of early diagnostic screening and preventative strategies for young individuals at risk for mental diseases, such as male PCE offspring.

Abstract
Cannabis use among pregnant people has increased over the past decade. This is of concern as prenatal cannabis exposure (PCE) is associated with cognitive, motor, and social deficits among offspring. Here, we examined resting-state functional connectivity (rsFC) of the salience network (SN)-a core neurocognitive network that integrates emotional and sensory information-in children with (vs. without) PCE. Using neuroimaging and developmental history data collected from 10,719 children (M ± SD = 9.92 ± 0.62 years; 47.9% female) from the Adolescent Brain Cognitive Development study, we assessed the impact of parent-reported PCE (before or after knowledge of pregnancy) on rsFC within and between the SN and five other core neurocognitive networks. We also evaluated whether SN rsFC mediated the association between PCE and child psychopathology. Results showed that PCE before (but not after) knowledge of pregnancy was associated with lower SN-ventral attention network (VAN) rsFC. Furthermore, psychotic-like experiences mediated the association between PCE and SN-VAN rsFC, and reversal of the model was also significant, such that SN-VAN rsFC mediated the association between PCE and psychotic-like symptoms. However, these mediation effects were no longer significant after the inclusion of covariates. Taken together, these findings suggest that developmental alterations in SN-VAN interactions may explain the previously reported association between PCE and elevated risk of child psychopathology.

Abstract
Although used therapeutically for millennia, cannabis has been a prohibited substance worldwide for most of the 20th Century. With revision of prohibitive regulations in many jurisdictions during the past 2 decades, cannabis is increasingly available to patients as a potential treatment option for various symptoms. Pain relief, sleep promotion and alleviation of distress, depression and anxiety are the most common reasons for cannabis use. Canada has been at the forefront of medical cannabis (MC) legislation revisions to enable and facilitate access for therapeutic use. Although initially viewed with caution and stigma, attitudes to cannabis in general have changed. Medical cannabis is identified as the herbal plant product sourced from a grower/producer and is not at present a regulated pharmaceutical product. Medical cannabis use is currently prevalent in Canada but has bypassed the rigorous study required for usual drug approval. Although uptake has been enthusiastic by patients, the medical community has voiced cautions and concerns. Access to medical cannabis is fairly easy once an approval document is obtained from a healthcare professional, but without obligation for medical or pharmacy oversight. The greatest concern is a dearth of sound clinical evidence for effects and harms. Emerging concerns include prevalent patient self-management with information based on personal research, an abundance of on-line information which may not always be accurate, the emergence of designated "cannabis clinics," potential risks to society due to accidents, and high cost of the legal medical product leading to access via the recreational market. With cannabis now entrenched in Canadian healthcare, physicians must be sufficiently knowledgeable to provide guidance that is evidence-based and will ensure personal and societal harm reduction. Examination of the changing culture of medical cannabis in Canada will provide insight for countries that may be anticipating similar revisions of cannabis regulations to allow cannabis access for their patient population and learn from the issues created by recreational legalization.

Abstract
Because of substantial limitations in available national data, such as inconsistencies among surveys and small sample sizes, the increased prevalence of cannabis use among adolescents since recreational legalization has not been directly observed. Nevertheless, both usage frequency and product potency have significantly increased, alongside alternative routes of delivery to smoking, such as vaping cannabis. Moreover, certain populations may be especially vulnerable to the effects of legalization. Regardless of differing state-level cannabis legalization status, the adverse consequences of cannabis on youth have clear negative impacts on mental health, medical symptoms, educational outcomes, and increased risk of addiction to other substances.

Abstract
BACKGROUND The goal of this study was to examine if in utero cannabis exposure predicted reduced birth size and if these effects were evident in specific growth parameters as early as the second trimester. METHODS Eligible women had an initial prenatal visit between January 1, 2010, and March 31, 2020, completed an anatomy ultrasound between 18-24 weeks' gestation, and had no self-reported alcohol, tobacco, or other biochemically verified drug use. The two primary study groups were cannabis users (n = 109) identified through self-report and urine toxicology screens, and a randomly selected control group of non-substance users (n = 171). Medical records were manually reviewed for background and medical information, anatomy ultrasound results, and birth size parameters. RESULTS After controlling for significant confounders, regression results indicated significant (p < .05) deficits in birth weight associated with cannabis exposure, with a trend for increasing weight effects beginning in the second trimester. A significant decrease in head circumference was evident as early as the second trimester, with differences remaining significant until birth. Significant overall length and specific bone length deficits were not predicted by cannabis exposure, at birth or earlier in gestation, after control for confounding. CONCLUSIONS Cannabis exposure predicted growth deficits at birth, with some effects evident as early as the second trimester. The biggest and earliest effects were seen for cranial size, with an adjusted deficit of more than 14 percentile points by birth. Overall weight was not impacted until at or near delivery.

Early pregnancy confirmation availability at crisis pregnancy centers and abortion facilities in the United States. Contraception 2023; 117:30-35.

Abstract
OBJECTIVES Crisis pregnancy centers (CPCs) seek to dissuade people from having abortions. Twenty-five states have policies supporting CPCs. We aimed: (1) to characterize access to early pregnancy confirmation at CPCs compared to abortion facilities nationwide and (2) to understand the role of state CPC policy in service access. STUDY DESIGN We conducted a national mystery caller study of 445 CPCs and geographically paired abortion facilities, posing as patients seeking pregnancy confirmation. Facility type (CPC vs abortion facility) was the primary exposure in Aim 1. Wait time to first available early pregnancy appointment was the primary outcome. In Aim 2, state-level CPC policy designation (supportive vs not supportive of CPCs) was the primary exposure. Difference in wait time ≥7 days to first available appointment between CPCs and paired abortion facilities was the primary outcome. RESULTS CPCs were more likely than abortion facilities to provide same-day appointments (68.5% vs 37.2%, p < 0.0001), and free pregnancy testing (98.0% vs 16.6%, p < 0.0001). The median wait to first available appointment at a CPC was 0 days (IQR 0,1), compared to 1 day at abortion facilities (IQR 0, 5), p < 0.0001. In states with supportive CPC policy environments, abortion facilities were less likely to have wait times exceeding their paired CPC by a week or more, compared to paired facilities in states with non-supportive CPC policy environments (p = 0.033). This remained true after adjusting for state abortion policy environment (p = 0.011). CONCLUSIONS Pregnancy confirmation is more accessible at CPCs compared to abortion facilities. Factors other than state-level CPC policies likely influence service accessibility. There is a need for improved access to pregnancy confirmation in medical settings. IMPLICATIONS Our findings demonstrating that pregnancy confirmation is more accessible at crisis pregnancy centers than at abortion facilities are predicted to be exacerbated in the wake of abortion clinic closures following the Dobbs v Jackson Women's Health Organization Supreme Court decision. This highlights the need for improved funding and support for pregnancy confirmation service delivery in medical settings, including abortion facilities.

Abstract
IMPORTANCE As rates of prenatal cannabis use increase and cannabis legalization spreads across the US, studies are needed to understand the potential impacts of legalization from the perspectives of pregnant individuals who use cannabis. OBJECTIVE To characterize pregnant individuals' perspectives on legalization of cannabis for adult use in California (effective in 2018) in relation to prenatal cannabis use behaviors and beliefs. DESIGN, SETTING, AND PARTICIPANTS This qualitative study was conducted in Kaiser Permanente Northern California, a large health care system with universal screening for self-reported cannabis use at entrance to prenatal care. Eighteen semistructured focus groups were conducted from November 17 to December 17, 2021, using a secure video conferencing platform with Black and White pregnant participants who self-reported cannabis use during early pregnancy. Data were analyzed from March to June 2022. MAIN OUTCOMES AND MEASURES Video-recorded interviews were transcribed and analyzed using thematic analysis to identify major themes and subthemes. RESULTS Among 53 participants (mean [SD] age, 30.3 [5.2] years), 23 (43%) identified as non-Hispanic Black and 30 (57%) identified as non-Hispanic White; 16 participants (30%) reported continued cannabis use at the time of recruitment. Major themes regarding the perceived impact of legalization included easier access (via retailers and delivery), greater acceptance (including reduced stigma and more discussions about prenatal cannabis use with health care practitioners), and trust in cannabis retailers (including safety and effectiveness of diverse products sold and perceptions of cannabis retailer employees as knowledgeable, nonjudgmental, and caring). Responses were mixed about whether retailer marketing and advertising were associated with prenatal cannabis use and whether legalization resulted in reduced concerns about Child Protective Services involvement. CONCLUSION AND RELEVANCE The findings of this qualitative study suggest pregnant individuals perceive cannabis legalization as having reduced barriers to prenatal cannabis use and that legalization has created challenges and opportunities for supporting the health of pregnant individuals. The results of this qualitative study highlight key areas that can be further explored in future educational materials, public health campaigns, and policy adaptations to address increasing rates of prenatal cannabis use.

Abstract
Cannabis use in pregnancy is associated with adverse perinatal outcomes, which are likely mediated by the placenta. However, the underlying mechanisms and specific vasoactive effects of cannabis on the placenta are unknown. Our objective was to determine the impact of chronic prenatal delta-tetrahydrocannabinol (THC, main psychoactive component of cannabis) exposure on placental function and development in a rhesus macaque model using advanced imaging. Animals were divided into two groups, control (CON, n = 5) and THC-exposed (THC, n = 5). THC-exposed animals received a THC edible daily pre-conception and throughout pregnancy. Animals underwent serial ultrasound and MRI at gestational days 85 (G85), G110, G135 and G155 (full term is ~ G168). Animals underwent cesarean delivery and placental collection at G155 for histologic and RNA-Seq analysis. THC-exposed pregnancies had significantly decreased amniotic fluid volume (p < 0.001), placental perfusion (p < 0.05), and fetal oxygen availability (p < 0.05), all indicators of placental insufficiency. Placental histological analysis demonstrated evidence of ischemic injury with microinfarctions present in THC-exposed animals only. Bulk RNA-seq demonstrated that THC alters the placental transcriptome and pathway analysis suggests dysregulated vasculature development and angiogenesis pathways. The longer-term consequences of these adverse placental findings are unknown, but they suggest that use of THC during pregnancy may deleteriously impact offspring development.

Reece AS, Hulse GK. State Trends of Cannabis Liberalization as a Causal Driver of Increasing Testicular Cancer Rates across the USA. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph191912759. [PMID: 36232059 PMCID: PMC9565972 DOI: 10.3390/ijerph191912759] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 09/18/2022] [Accepted: 09/30/2022] [Indexed: 05/16/2023]
Abstract
BACKGROUND The cause of the worldwide doubling-tripling of testicular cancer rates (TCRs) in recent decades is unknown. Previous cohort studies associated cannabis use with TCR including dose-response relationships but the contribution of cannabis to TCRs at the population level is unknown. This relationship was tested by analyzing annual trends across US states and formally assessed causality. Four US datasets were linked at state level: age-adjusted TCRs from Centers for Disease Control Surveillance Epidemiology and End Results database; drug use data from annual National Survey of Drug Use and Health including 74.1% response rate; ethnicity and median household income data from the US Census Bureau; and cannabinoid concentration data from Drug Enforcement Agency reports. Data was processed in R in spatiotemporal and causal inference protocols. RESULTS Cannabis-use quintile scatterplot-time and boxplots closely paralleled those for TCRs. The highest cannabis-use quintile had a higher TCR than others (3.44 ± 0.05 vs. 2.91 ± 0.2, mean ± S.E.M., t = 10.68, p = 1.29 × 10-22). A dose-response relationship was seen between TCR and Δ9-tetrahydrocannabinol (THC), cannabinol, cannabigerol, and cannabichromene (6.75 × 10-9 < p < 1.83 × 10-142). In a multivariate inverse probability-weighted interactive regression including race and ethnic cannabis exposure (ECE), ECE was significantly related to TCR (β-estimate = 0.89 (95%C.I. 0.36, 2.67), p < 2.2 × 10-16). In an additive geospatiotemporal model controlling for other drugs, cannabis alone was significant (β-estimate = 0.19 (0.10, 0.28), p = 3.4 × 10-5). In a full geospatial model including drugs, income and ethnicity cannabinoid exposure was significant (cannabigerol: β-estimate = 1.39 (0.024, 2.53), p = 0.0017); a pattern repeated at two spatial and two temporal lags (cannabigerol: β-estimate = 0.71 (0.05, 1.37), p = 0.0.0350; THC: β-estimate = 23.60 (11.92, 35.29), p = 7.5 × 10-5). 40/41 e-Values > 1.25 ranged up to 1.4 × 1063 and 10 > 1000 fitting causal relationship criteria. Cannabis liberalization was associated with higher TCRs (ChiSqu. = 312.2, p = 2.64 × 10-11). Rates of TC in cannabis-legal states were elevated (3.36 ± 0.09 vs. 3.01 ± 0.03, t = 4.69, p = 4.86 × 10-5). CONCLUSIONS Cannabis use is closely and causally associated with TCRs across both time and space and higher in States with liberal cannabis legislation. Strong dose-response effects were demonstrated for THC, cannabigerol, cannabinol, cannabichromene and cannabidiol. Cannabinoid genotoxicity replicates all major steps to testicular carcinogenesis including whole-genome doubling, chromosomal arm excision, generalized DNA demethylation and chromosomal translocations thereby accelerating the pathway to testicular carcinogenesis by several decades.

Abstract
Introduction: Medical cannabis (marijuana) use is legal in 33 U.S. states and the District of Columbia. Clinicians can play an important role in helping patients access and weigh potential benefits and risks of medicinal cannabis. Accordingly, this study aimed to assess clinician beliefs and practices related to cannabis. Methods: Data are from 1506 family practice doctors, internists, nurse practitioners, and oncologists who responded to the 2018 DocStyles, a web-based panel survey of clinicians. Questions assessed medicinal uses for and practices related to cannabis and assessed clinicians' knowledge of cannabis legality in their state. Logistic regression was used to assess multivariable correlates of asking about, assessing, and recommending cannabis. Results: Over two-thirds (68.9%) of clinicians surveyed believe that cannabis has medicinal uses and just over a quarter (26.6%) had ever recommended cannabis to a patient. Clinicians who believed cannabis had medicinal uses had 5.9 times the adjusted odds (95% confidence interval 3.9-8.9) of recommending cannabis to patients. Beliefs about conditions for medical cannabis use did not necessarily align with the current scientific evidence. Nearly two-thirds (60.0%) of clinicians surveyed incorrectly reported the legal status of cannabis in their state. Discussion: Findings suggest that while clinicians believe that cannabis has medicinal uses, they may not have a full understanding of the scientific evidence and may not accurately understand their state-based policies for cannabis legalization and use. Given that clinicians are responsible for recommending medicinal cannabis in most states that have legalized it, ongoing education about the health effects of cannabis is warranted.

Abstract
IMPORTANCE Rates of prenatal cannabis use are increasing alongside perceptions that cannabis is a harmless therapeutic for pregnancy-related ailments, while rates of prenatal use of alcohol and tobacco are decreasing. It is important to examine whether cannabis use during pregnancy is increasing similarly among patients with and patients without co-occurring substance use. OBJECTIVES To examine trends in cannabis polysubstance use during pregnancy and to test differences in cannabis use over time among pregnant individuals who use only cannabis vs those who use cannabis and other substances. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional time-series study used data from 367 138 pregnancies among 281 590 unique pregnant patients universally screened for prenatal substance use as part of standard care in Kaiser Permanente Northern California from January 1, 2009, to December 31, 2018. Statistical analysis was performed from October 5, 2021, to April 18, 2022. EXPOSURES Time (calendar year). MAIN OUTCOMES AND MEASURES Use of substances during early pregnancy was assessed via universal screening with a self-administered questionnaire (for cannabis, alcohol, stimulants, and nicotine) and/or positive results of a urine toxicology test (for cannabis, alcohol, stimulants, and pharmaceutical opioids), and data were extracted from the electronic health record. RESULTS The study sample of 367 138 pregnancies from 281 590 unique pregnant patients (median gestation at time of screening, 8.6 weeks [IQR, 7.3-10.6 weeks]) was 25.9% Asian or Pacific Islander, 6.6% Black, 25.8% Hispanic, 38.0% non-Hispanic White, and 3.6% other race or ethnicity; 1.1% were aged 11 to 17 years, 14.9% were aged 18 to 24 years, 61.9% were aged 25 to 34 years, and 22.1% were aged 35 years or older; and the median neighborhood household income was $70 455 (IQR, $51 563-$92 625). From 2009 to 2018, adjusted rates of use of only cannabis during pregnancy (no other substances) increased substantially from 2.39% (95% CI, 2.20%-2.58%) in 2009 to 6.30% (95% CI, 6.00%-6.60%) in 2018, increasing at an annual relative rate of 1.11 (95% CI, 1.10-1.12). The rate of use of cannabis and 1 other substance also increased (annual relative rate, 1.04 [95% CI, 1.03-1.05]), but not as rapidly (P < .001 for difference), while the rate of use of cannabis and 2 or more other substances decreased slightly (annual relative rate, 0.97 [95% CI, 0.96-0.99]). Adjusted rates of prenatal use of cannabis and alcohol (1.04 [95% CI, 1.03-1.06]) and cannabis and stimulants (1.03 [95% CI, 1.01-1.06]) increased over time, while rates of prenatal use of cannabis and nicotine (0.97 [95% CI, 0.96-0.98]) decreased. CONCLUSIONS AND RELEVANCE In this cross-sectional time-series study, rates of prenatal cannabis use during early pregnancy increased significantly more rapidly among patients without co-occurring substance use, which could reflect increased acceptability of cannabis and decreased perceptions of cannabis-related harms. Furthermore, increased rates of use of cannabis with alcohol and stimulants warrant continued monitoring.

Abstract
Cannabis is the most commonly used federally illegal drug in the United States and world, especially among people of reproductive age. In addition, the potency of cannabis products has increased significantly in the past decade. This is concerning because the available evidence suggests an adverse effect from cannabis exposure on male and female reproductive health. Exposure to cannabinoids may have differential impacts on female reproductive health across a woman's lifespan, from preconception to pregnancy, throughout lactation, and during menopause. Even more, cannabis use has been associated an adverse effect on fetal outcomes, and longer-term offspring health and developmental trajectories. Despite the prevalence of cannabis use, there is limited available evidence regarding its safety, especially in regard to reproductive health, pregnancy and lactation. The biological effects of cannabis are mediated by the endocannabinoid system and studies have reported the presence of cannabinoid receptors in the male and female reproductive tract, on sperm and the placenta, suggesting the endocannabinoid system plays a role in regulating reproduction. Cannabis use can impact male and female fertility and has been associated with altered reproductive hormones, menstrual cyclicity and semen parameters. Use of cannabis in males has also been associated with erectile dysfunction, abnormal spermatogenesis, and testicular atrophy. In females, cannabis use has been associated with infertility and abnormal embryo implantation and development. The main psychoactive component of cannabis, delta-9-tetrahydrocannabinol (THC), can also cross the placenta and has been detected in breastmilk. Maternal cannabis use during pregnancy and lactation has been associated with adverse effects including small for gestational age infants, preterm birth, fetal neurodevelopmental consequences, and impaired offspring sociobehavioral and cognitive development. The prevalence of cannabis use to alleviate menopausal symptoms has also increased despite the limited information on its benefits and safety. As cannabis use is on the rise, it is critical to understand its impact on reproductive health and offspring developmental outcomes. This is an understudied, but timely subject, with much needed information to guide healthcare providers and those interested in conceiving, or that are pregnant and lactating, as well as those at the end of their reproductive time span.

Abstract
Abstract
Objectives
This study aimed to identify recommendations given to breastfeeding individuals by Canadian cannabis dispensary employees, since the legalization of recreational cannabis in 2018.
Methods
This was a nationwide cross-sectional study conducted from November 2020 to January 2021. A mystery caller approach was used to identify recommendations given to breastfeeding individuals seeking a product for “relaxation.” This study was modelled on similar studies which assessed recommendations given to pregnant women looking for cannabis products to manage nausea and vomiting (Vastis V, Shea AK, Vincent S, Metz TD. 275: Are canadian cannabis dispensaries counselling pregnant women appropriately? Am. J. Obstet. Gynecol. 2020;222: S187.(Abst). Lusero I, Paltrow LM, Rosenbloom N. Recommendations from cannabis dispensaries about first-trimester cannabis use Obstet Gynecol 2018;132:781–2.). The primary outcome was the recommendation of a cannabis product. Secondary outcomes included stated benefits of cannabis, recommended discussion with health care provider, length of call, rationale for recommendation, and reported source of information on which the recommendation was based.
Results
The majority (79.4%) of employees of the 714 Canadian dispensaries contacted recommended against a cannabis product for “relaxation” while breastfeeding. The recommendations from dispensary employees were often (80%) provided without a specific reason, whereas a minority referenced published research (2%) and opinion (17.6%). Cannabis products were rarely (3.3%) classified as safe in breastfeeding. Approximately 76.6% of dispensary employees recommended contacting a health care provider, while 2.4% recommended against.
Conclusions
Although a high proportion of dispensary employees recommended against using a cannabis product during lactation, there were still 20.6% that did recommend use, which contrasts the current public health guidelines and is not supported by the paediatric and obstetric societies. These findings highlight the need for further education about the safety of cannabis products while breastfeeding.

Prostaglandins Leukot Essent Fatty Acids 2022; 180:102440. [PMID: 35490598 DOI: 10.1016/j.plefa.2022.102440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 04/18/2022] [Accepted: 04/19/2022] [Indexed: 11/21/2022]
Abstract
The interest on the endocannabinoid system (ECS) in human reproduction has grown due to its involvement in placenta development, which led to growing concerns over pregnant cannabis consumer's impact on pregnancy outcome. The endocannabinoids anandamide (AEA) and 2-arachidonoylglycerol (2-AG) modulate placental trophoblast proliferation and apoptosis. However, their role on other placentation events such as angiogenesis and invasion are unknown. Using the human extravillous trophoblast HTR-8/SVneo cells, a well-accepted model of first trimester extravillous trophoblast (EVT), this study aims to investigate whether AEA and 2-AG can modulate the expression of angiogenesis- and invasion-related factors. Transcript analysis of angiogenic factors of the vascular endothelial growth factor (VEGF) and matrix metalloproteinase (MMP) protein family demonstrated the ability of AEA to increase VEGF-C and VEGFR3 expression via cannabinoid receptors CB1 and CB2 while the placental growth factor (PlGF) was increased through CB1. Moreover, an increase in VEGFR1, sFLT1, VEGFR2, MMP-2 and TIMP-1 independent of cannabinoid receptor activation was verified. However, 2-AG only increased PlGF transcript through CB1/CB2 activation. Both endocannabinoids stimulated HTR8/SVneo endothelial-like tube formation. As for the wound healing assay, only 2-AG was able to increase the percentage of wound closure. Moreover, the data demonstrated that both AEA and 2-AG, via cannabinoid receptors, activated the STAT3 signaling pathway. Distinct effects were observed on transcription factor HIF-1α and AKT phosphorylation that decreased with both endocannabinoids. Although different angiogenic and migration factors are affected the results obtained in this work showcase once more the ability of the endocannabinoids to modulate key processes in placental physiology.
