Study Summary
The goal of this study is to learn about the effects of combining alcohol with cannabis concentrate products which contain high levels of THC. The main question\[s\] it aims to answer are, 1) How does the order in which someone consumes THC and alcohol in a given co-use session impact outcomes such as blood alcohol level, heart rate or subjective drug effects, and 2) how does THC percentage in cannabis influence outcomes following alcohol and cannabis co-administration. Participants will be scheduled for our mobile lab to come to their residence. During the session, they will: * consume a standardized dose of alcohol as well as use their own preferred cannabis concentrate product. * they will then remain in our mobile lab for about 4 hours and complete some surveys as well as do some cognitive tasks on an iPad every 30 minutes. * They will also have their blood drawn three times throughout the session, and will periodically be asked to blood into a breathalyzer to measure blood alcohol level. Researchers will compare people who use alcohol prior to cannabis to those who use cannabis prior to alcohol to determine whether order of use impacts outcomes.
Primary Outcome
Breath alcohol level will be measured using a breathalyzer repeatedly during the experimental session
