“…Another explanation could be that the Kaiser study focused on exposure in the first trimester while our study used blood specimens collected in the second trimester. Reported use of cannabis is higher in the first trimester than in the second trimester [48].…”

There are known health concerns linked to prenatal tobacco and cannabis exposures. This study aims to objectively determine the level of exposure to tobacco and cannabis in pregnant individuals from six race/ethnicity groups (Black, Hispanic, Asian Indian, Native American, Vietnamese, and White) in the first three years following legalization of recreational marijuana use in 2018 in California. We used a cross-sectional sample of prenatal screening program participants (2018–2020) from southern and central California (N = 925). Exposures were estimated by a lab analysis of cotinine (tobacco) and 11-hydroxy-Δ9-tetrahydrocannabinol (OH-THC, cannabis) in banked serum. Disparities in tobacco exposure were evident, with Black subjects experiencing the highest smoking rate (16%) followed by Native American (10%) and White (8%) subjects, and ≤2% among Hispanic, Asian Indian, and Vietnamese subjects. Environmental tobacco exposure generally showed a similar pattern of exposure to tobacco smoking across race/ethnicity groups. Cannabis detection ranged from 5% among Hispanic subjects to 12% and 13% among White and Black subjects, respectively, and was higher among tobacco users and those exposed to environmental tobacco smoke than those with no cotinine detected. Tobacco and cannabis exposure were generally greatest in younger subjects and those with indices of a lower economic status; however, among Black subjects, cannabis exposure was greatest in older subjects and those with a higher socioeconomic status. Race/ethnicity, age, and socioeconomic factors can inform targeting of high-exposure groups for intervention.

“…Along with increasing legalization of cannabis for medical and recreational use, use of cannabis during pregnancy has increased from 6.3% of pregnant people in 2002 to 16% in 2020, according to the National Survey on Drug Use and Health 1 . Midwives need to have accurate information in order to counsel clients accurately about effects of cannabis use.…”

“…1,2 For instance, based on the US National Survey on Drug Use and Health (NSDUH), from 2002 to 2020, the prevalence of cannabis use in the first, second, and third trimesters increased from 6.3%, 1.9%, and 2.0% in 2002 to 16.0%, 4.2%, and 4.7% in 2020, respectively. 2 The accumulating evidence shows that cannabis use is associated with an increased risk of adverse events from the preconception to postpartum period. A recent study of those with a previous pregnancy loss found that preconception cannabis use was associated with 41% reduced fecundability after adjusting for confounders.…”

Background: Large-scale longitudinal studies with biological samples are needed to examine the associations between prenatal cannabis use and birth and developmental outcomes. Objectives: The aim of this study was to understand the feasibility and acceptability of collecting umbilical cord tissue for the purpose of cannabis use testing in a community sample. Design: This is a mixed methods research study consisted of a prospective cohort study and a qualitative descriptive study. Methods: This study was conducted in Vancouver, British Columbia between January 2021 and August 2022. Participants were recruited during pregnancy, and the umbilical cord tissues were collected at birth and tested for the presence of cannabinoids. After the completion of the study, participants completed an online open-ended questionnaire about their overall experience. Data were analyzed using descriptive and thematic analyses. Results: Among the 85 eligible individuals, 57 people (67%) consented to the study. The cord tissue was collected for 39 participants (68.4%). The collection rates for participants with vaginal, elective, and emergency cesarean delivery were 73.0%, 71.4%, and 53.8%, respectively, and for those with spontaneous and induced labor were 81.5% and 50%, respectively. Four (7.0%) and seven participants (12.3%) reported prenatal cannabis use in direct and probing self-report questions, respectively. The agreement between any self-report and cord tissue test was moderate (kappa 0.53, 95% confidence interval 0.06–0.99). Qualitative findings were classified into five themes. Conclusion: The collection of cord tissue was perceived acceptable by most participants. Implementation of collection protocols for complex labors, a central hospital unit to liaise direct communications and active participants’ involvement might increase the feasibility of future studies.
