Perinatal Cannabis Use and Cannabis Use during Breastfeeding: the Role of Health Care Workers

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 HCWdiscussing 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-ofmouth (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.
