Figure 3. Categorization of Storefront Retail Policy Indicating the Pre–Recreational Cannabis Legalization (RCL) Medical Policy and Post-RCL Adult-Use Policy.

In the period pre-RCL implementation, pregnancies were grouped based on whether medical retail was allowed or banned in individuals’ jurisdictions. In the period post-RCL implementation, pregnancies were grouped based on whether adult-use retail was allowed or banned in each jurisdiction at the time of screening (corresponds to analyses in Figure 2). Initially, 217 of the 244 jurisdictions (88.9%) had the same policy for medical as for adult-use storefront retailers (eg, both allowed or both banned). By the end of the study period, 51 jurisdictions (20.9%) changed policies and 238 jurisdictions (97.5%) enacted the same policy for medical and adult-use storefront retailers.
