Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will examine the effects of doses of alcohol/placebo and doses of opioid/placebo, alone and in combination. The primary outcomes are related to pharmacodynamic measures (subjective ratings of drug liking and other abuse-related effects; physiological outcomes) to determine the interaction effects of these compounds.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Alcohol

Participants will receive experimental doses of active or placebo alcohol, p.o. Alcohol/placebo will be administered once per session.

Group Type EXPERIMENTAL

Alcohol

Intervention Type DRUG

Active alcohol or placebo, administered orally

Opioid Agonist

Participants will receive non-therapeutic, experimental doses of an active opioid agonist or placebo. Active opioid agonist/placebo will be administered once per session and will be administered orally

Group Type EXPERIMENTAL

Opioid Agonist

Intervention Type DRUG

Active opioid agonist or placebo, administered orally

Opioid Agonist/Alcohol Combination

Participants will receive non-therapeutic, experimental doses of active opioid/placebo in combination with experimental doses of active alcohol placebo. Opioid/placebo and alcohol/placebo doses will be administered once during each session. It is possible to receive both active drugs on the same day. Both opioid and alcohol doses will be administered orally.
