For the most part, teens are taking better care of themselves today than in the past, and they are well informed about the downsides to drug taking. According to NIDA's Monitoring the Future survey--a national survey of 8th, 10th, and 12th graders--past-year use of illicit drugs other than marijuana was down from recent peaks in all three grades in 2016. Also notable is the decrease in tobacco use, which is now at the lowest rate in the survey's history for all three grades.

However, there are still areas that cause concern. For example, almost 36 percent of seniors reported past-year marijuana use. Also, misuse of prescription medications can be can dangerous and addictive, but nearly 6 percent of seniors reported past-month use of prescription amphetamines. In addition, teens are more likely to use electronic cigarettes than regular cigarettes, but many don't even know what's actually in the vapor they're inhaling.
