Drugs & Alcohol Chat Day is a live, online chat held between teen students and scientists during a 10 hour period. During the event, thousands of students from US high schools ask questions about drugs and alcohol use, including health effects, how to help friends or family who are using substances, and what causes addiction.

US high schools can now register for the 10th annual Drugs & Alcohol Chat Day, a web chat to be held on January 26. Registrations are taken on a first–come, first-served basis and are limited to about 100 schools. The event is coordinated by the National Institute on Drug Abuse (NIDA) in partnership with the National Institute on Alcohol Abuse and Alcoholism, both part of the National Institutes of Health.
