We need a campaign against teen marijuana use | Opinion

There’s good news and bad news when it comes to teen drug and alcohol use. The good news is that fewer teens are drinking, a trend that has been steadily improving over the last two decades. The negative is that cannabis seems to be picking up alcohol’s slack.

The research is still evolving, but the decline in teen drinking likely stems from a mix of policies and public health campaigns. The same level of effort should be applied to discouraging teen cannabis use — and quickly.
