More eighth graders are now using marijuana, along with more illegal drugs in general.

A new study released from the National Institute on Drug Abuse finds 16 percent of eighth graders reported using marijuana this year. That's up from 14.5 percent last year.

There was one bit of good news: teens are now drinking less than they used to, and experts reveal alcohol use is now at historically low levels.
