I agree that a lot of people are using this for questionable medical purposes, and there's a lot of snake oil around, as well as harmful self medicating. However, though I am not super steeped in this, I do know there are some prominent exceptions. I think CBD for epilepsy is one. There is an FDA approved CBD treatment for epilepsy, brand name epidiolex (had to google that).
