Recent research shows fewer teenagers are using illicit drugs and alcohol, and Nora Volkow, director of the National Institute on Drug Abuse, suspects that this trend directly correlates to the rise of digital devices. Volkow's upcoming research study will consider the possible role interactive media such as smartphones and computers play in the trend. Dr. Volkow describes interactive media as “an alternative reinforcer” to drugs, adding that “teens can get literally high when playing these games.”
