Preventing marijuana sales to intoxicated customers to reduce impaired driving
Policy and Training Intervention in Responsible Marijuana Sales Practices to Reduce the Risk of Selling to Intoxicated Customers
This project trains marijuana store staff and strengthens store policies so intoxicated customers are less likely to be sold marijuana, helping keep roads safer for everyone.

What this research studies
If you live in the Portland area, this work focuses on licensed recreational marijuana stores and aims to stop sales to customers who are clearly intoxicated. Researchers will send trained pseudo-intoxicated patrons to try purchases to see how often stores sell to intoxicated people, then provide a policy-and-training program for store managers and staff using an online responsible-vendor course. They will compare store behavior before and after the intervention to see whether refusals of service increase. The overall aim is to reduce marijuana- and alcohol-related impaired driving and other harms in the community.
Who could benefit from this research
Good fit: Adults in the greater Portland, Oregon metro area—especially store employees, managers, and community members affected by marijuana and alcohol-impaired driving—are the main groups linked to this work.
Not a fit: People who live outside the study area or who are not affected by retail marijuana sales or impaired driving may not see direct benefits from this project.
Why it matters
Potential benefit: If successful, fewer intoxicated people would obtain marijuana and there could be reductions in impaired driving, crashes, and related injuries.
How similar studies have performed: Similar policy-and-training approaches have reduced sales to intoxicated patrons in alcohol settings, but applying those methods to legal marijuana retail is relatively new.
