NCT ID NCT07368894

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at whether adding a brief online personalized feedback program to standard screening and counseling can reduce impaired driving in young adults aged 18-30. Researchers will enroll 600 participants in Washington State who have already received standard screening. Half will get the extra online program, and the other half will not. The main goal is to see if the program lowers the number of times people drive while impaired by both alcohol and cannabis over three months.
