Understanding Dual Marijuana and Tobacco Use in Young Adults

This study is looking for 120 young adults, aged 18-25, who currently smoke both marijuana and tobacco. The goal is to better understand why young adults use both substances, which can increase health risks like cancer. You would participate in four in-person sessions where researchers will observe your reactions to marijuana and tobacco-related items and ask about your cravings. The study will measure changes in your self-reported cravings for both marijuana and tobacco up to 40 days after your last session. This research aims to help develop better ways to help young adults stop using these substances. The study's current status is unclear.

Cannabis craving will be assessed following neutral cue exposure and then cannabis cue exposure. The primary outcome will be change in cannabis craving.
