Teen drug use, binge drinking, and smoking are all on the decline, according to a new federal report. The study found that substance dependence or abuse problems among 12-17-year-olds dropped from 8.9% to 5.2% from 2002 and 2013, and rates of drug abuse went from close to 12% to under 9%. However, the reasons behind these drops is somewhat of a mystery, as the percentage of teens who have seen prevention messages during the same time period has actually declined. (CBS, Newsweek)
