Teens are heeding the message to stay away from cocaine and cigarettes.
But when it comes to marijuana, not so much.
An annual survey by the National Institute on drug use found that 60 percent of high school seniors don't think regular pot use is harmful to their health.
More than a third of them admitted to using it within the past 12 months.
Nearly seven percent say they smoke marijuana daily.
That's nearly triple from what it was 20 years ago.
Researchers say going forward they'll explore the link between teen's drug use and states that allow the use of medical marijuana.
Some teens report getting their hands on pot from someone else's prescription.
