This study, published in the American Journal of Preventive Medicine, investigated the associations between cannabis retail laws and relevant experiences (e.g., advertising exposure) among young adults, who have the highest use prevalence.

The researchers examined three categories of nonmedical cannabis retail-related laws: operational restrictions (e.g., operating hours, zoning restrictions), advertising restrictions (by media channels, health claims, giveaways/discounts), and required warnings (in ads, at retailers). 1,487 U.S. young adults in 19 states with nonmedical cannabis retail from June−November 2023 were surveyed. They found that certain expected variables held true to their predicted outcomes, while other laws showed no association with outcomes.
