Sex, drugs and drinking are hardly new concerns when it comes to our teens.

As many states grapple with news that some of these devastating behaviors are on the rise among young people, a new study out of New Hampshire shows teens are actually doing what mom and dad have been asking of them.

A 2015 New Hampshire Youth Risk Behavior Survey shows that teenagers’ use of tobacco, illegal prescription drugs and alcohol are down, and seatbelt and bicycle helmet use are up. Marijuana use specifically in this latest survey dropped from 31 percent in 2003 to 22 percent last year, bucking a national trend. The number of teens having sex has also reportedly dropped from 47 percent in 2011 to 39 percent last year.

That’s the good news.

The bad news: “Alarming trends continue in areas of texting and driving and heroin use,” the state Department of Health and Human Services said in a statement about the findings. The use of heroin has remained constant for 12 years. Texting and driving has gone down by 4 percent, with girls admitting to the practice more than boys. One in 4 teens has now also tried e-cigarettes.
