NIDA and the National Institute of Alcohol Abuse and Alcoholism (NIAAA) invite international substance abuse professionals to host events during the NIDA/NIAAA National Drug and Alcohol Facts Week (NDAFW), January 23–29, 2017. The international health information program supports locally planned and hosted school and community events that provide teens with scientific facts about drugs and alcohol. These local events use NIDA and NIAAA evidence—and free, downloadable materials—to counteract the myths about drugs and alcohol that teens get from the internet, social media, TV, movies, music, or from friends. In 2016, drug abuse professionals in 13 nations, many of them former NIDA Hubert H. Humphrey Drug Abuse Research Fellows, held events in conjunction with NDAFW.
