Like many people, Chris Leibowitz, of Centreville, Virginia, first tried marijuana at a young age—in his case, beginning at age 13, when cigarettes and alcohol were relatively difficult to buy, but marijuana was available, and his friends downplayed the risks he’d heard about at school. He was high on marijuana the first time he tried cocaine a few years later, he explained as a featured speaker at a press conference held to announce the latest findings from the National Institute on Drug Abuse (NIDA) annual Monitoring the Future survey of teen drug use.
