Developing Predictive Models to Distinguish Alcohol Use, Cannabis Use and Co-use: An Exploration of Electroencephalography (EEG) Metrics and Traditional Intoxication Measures

Summary

This is a randomized, parallel-group study designed to explore the differences between cannabis intoxication, alcohol intoxication and co-intoxication involving both alcohol and cannabis, utilizing electroencephalography (EEG) as well as more traditional intoxication measures such as breath alcohol concentration and balance metrics. If eligible for the study, participants will be randomized to complete one study session in our mobile laboratory, during which they will use either alcohol, cannabis (which will be self-administered, ad libitum) or both alcohol and cannabis.
