Brief Summary
The study will employ a combined laboratory-ambulatory design. Participants will engage in ambulatory assessment over the course of 14 days, wearing biosensors assessing transdermal alcohol concentration (TAC) and providing breathalyzer readings in real-world contexts. Also during this period, participants will attend three laboratory alcohol-administration sessions scheduled at one-week intervals, with alcohol dose and rate of consumption manipulated within and between participants, respectively. Laboratory visits will also double as ambulatory orientation, check-in, and close-out sessions.
Eligibility Criteria
Inclusion Criteria: * 21 years or older * drink alcohol at least 2x weekly Exclusion Criteria: * psychological or medical conditions that might contraindicate alcohol-administration * history of adverse reaction to type and amount of beverage used in the study * currently seeking treatment for alcohol use disorder * does not drink alcohol regularly * taking drugs or medications for which alcohol consumption would be contraindicated * women who are pregnant or are attempting to become pregnant
