NCT ID NCT05929677
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looks at how impulsivity and the way people feel when drinking alcohol are connected in young adults aged 21-25. Researchers will give alcohol or a placebo intravenously and track participants' responses in the lab and in daily life using a phone app. The goal is to find new targets for preventing or treating alcohol use disorder.
