The National Drug and Alcohol Facts Week marks its 11th anniversary March 22-28, 2021, encouraging communities around the country to Shatter the Myths about substance use and addiction. NDAFW is a joint initiative of the National Institute of Drug Abuse (NIDA) and the National Institute of Alcohol Abuse and Alcoholism (NIAAA), which are both part of the National Institutes of Health (NIH). NDAFW is an annual, week-long observance in which local educational events link teens with science-based facts about drugs and alcohol.
