Marijuana’s official designation as a Schedule 1 drug — something with “no accepted medical use” — means it is pretty tough to study you could try this out.

In addition, researchers say there are many other potential ways marijuana might affect health that they want to understand better.

A massive new report released in January 2017 by the National Academies of Sciences, Engineering, and Medicine (NASEM) helps sum up exactly what we know — and perhaps more importantly, what we don’t — about the science of weed.

Pot also contains cannabidiol (CBD), and this chemical — while not responsible for getting you high — is thought to be responsible for many of marijuana’s therapeutic effects, from pain relief to a potential treatment for certain kinds of childhood epilepsy.

The new report also found conclusive or substantial evidence (the most definitive levels) that cannabis can be an effective treatment for chronic pain, which could have to do with both CBD and THC. Pain is also “by far the most common” reason people request medical marijuana, according to the report.
