Prenatal cannabis use is associated with adverse perinatal outcomes1 and is increasing with expanding legalization.2,3 While it is known that retail availability of cannabis is associated with adult cannabis use,4,5 it is less clear whether living closer to a cannabis retailer or in a neighborhood with greater cannabis retailer density is associated with prenatal cannabis use. This cross-sectional study assessed the association between recreational use cannabis retailer availability and cannabis use among pregnant women served by the Kaiser Permanente Northern California (KPNC) heath system during the first year of California’s 2018 initiation of recreational cannabis sales.

Prenatal cannabis use is associated with adverse perinatal outcomes[1] and is increasing with expanding legalization.[2,3] While it is known that retail availability of cannabis is associated with adult cannabis use,[4,5] it is less clear whether living closer to a cannabis retailer or in a neighborhood with greater cannabis retailer density is associated with prenatal cannabis use
Kaiser Permanente Northern California (KPNC) serves more than 4 million patients and universally screens pregnant women for prenatal cannabis use through self-report and urine toxicological testing at entrance to prenatal care
