But doctors don't prescribe raw herbs or even extracts. They are found in the grocery store, not the pharmacy. I agree many herbs are in fact medicinal. I think your definition of a drug is too broad. Lots of things would be technically drugs that no one thinks of that way. Black pepper activates the CB2 receptor but are you going to claim the world is full of pepper-heads that need their drug fix first thing every morning; cross-addicted to eggs?
