The goal of this small (n=75) proof-of-concept randomized clinical trial is to test the effects of transcranial alternating current stimulation (tACS) during motivational interviewing (MI) sessions with participants who drink at above the low-risk level. Participants will be randomized to receive either MI with active stimulation, MI with sham stimulation, or a delayed treatment group that receives MI with no stimulation. Measures will include brain imaging, alcohol use, cannabis use, risk-taking behavior, emotions, and others. Participants who are randomized to the delayed-treatment group will not receive brain imaging.
