Good news: US teens consuming less alcohol, tobacco and drugs

The use of alcohol, marijuana, prescription medications and illicit substances declined among U.S. teens again in 2016, continuing a long-term trend, according to a study released on Tuesday by the National Institutes of Health. According to the study, marijuana and e-cigarettes are more popular among teens than regular tobacco, with a large drop in the use of tobacco cigarettes among 8th, 10th and 12th graders. Some positive news comes from the youngest participants. Past-month use of marijuana among eighth-graders decreased to 5.4% in 2016 from 6.5% in the previous year.
