Summary
This study looked at 162 young adults (ages 18-24) in Texas who drink and use marijuana regularly. Researchers wanted to understand why they choose to use or not use protective strategies, like pacing drinks or avoiding risky situations. The goal is to make future prevention programs more effective by focusing on motivations and barriers.
