Treatments tested in this trial
alcohol
DrugDuring the alcohol administration session participants will receive a single administration of alcohol (0.5 g/kg) mixed with lemon lime soda. Participants will consume the drink within 5 min.
Stress-Induction
BehavioralThe stress-induction procedure is the Cold Pressure Test \[CPT\]) stressor. The bilateral foot CPT requires participants to submerge both feet in ice-cold water (24°C) for 3 minutes.
PT150
DrugParticipants will ingest PT150 (0, 225, 450 mg) twice daily (e.g., 0800, 2000h) for 5 five days prior to the conduct of the experimental sessions. The sequence of PT150 doses will be quasi-random such that participants will be maintained on the lower dose of PT150 (i.e., 225 mg twice/day) before the higher dose.

Trial outcomes
Primary outcomes
Change in salivary cortisol (alcohol)
Salivatory samples will be collected before and periodically after the alcohol challenge procedure for 120 minutes using cotton swab salivettes.
Change in salivary cortisol (stress induction)
Salivatory samples will be collected before and periodically after the stress induction procedure for 120 minutes using cotton swab salivettes.
Change in Alcohol Demand (stress induction)
A drug purchasing task will be used to determine how many hypothetical doses of their preferred alcohol beverage participants would purchase across varying prices.
