What this research studies

You and other young people from different communities would provide information about alcohol and marijuana use while researchers map local laws and nearby stores. They will compare places with different rules and enforcement to see how those settings relate to single substance use and using both substances together. The team uses surveys, local policy reviews, and records about retail availability, and may follow youth over time to see changes. This helps show how community rules, store access, and enforcement shape opportunities and risks for young people.

Who could benefit from this research

Good fit: Ideal participants are adolescents and young adults (roughly ages 12–21) living in communities with different local alcohol and marijuana policies.

Not a fit: People outside the adolescent and young adult age range or those living in areas without variation in local alcohol or marijuana rules are less likely to directly benefit from participating.

Why it matters

Potential benefit: If successful, the findings could help communities shape local policies to reduce youth alcohol and marijuana co-use and related harms.

How similar studies have performed: Previous research has linked state-level alcohol and marijuana policies to use, but combining local policy, retail availability, and youth co-use over time is less common and partly novel.
