ATLANTA, Ga. -- There's good news and bad news when it comes to teen health: fewer teens are getting into car accidents and more are wearing seat belts, but more are also texting behind the wheel.
A new survey by the Centers for Disease Control and Prevention found that car crashes remain the number one cause of death among high schoolers, but there has been a more than 40percent reduction in those deaths over the last decade.
Researchers say more kids are wearing seat belts and avoiding cars driven by people who had been drinking alcohol.
However, distracted driving habits are on the rise. One third of teens say they have emailed or texted while driving.
The survey also showed marijuana use went up since 2009. Nearly a quarter of teens had recently smoked marijuana while 20percent had smoked cigarettes.
CDC researchers also found nearly one in five teens had been bullied on school property and 16percent percent had been bullied online.
