30 Marijuana Plants for Back Pain – Valid Excuse?

The reason I’m writing this article is because of an article I read of a bloke from the UK who was busted with 30-cannabis plants and avoided jail by claiming it was for a “bad back”. Some people may  scoff at the notion that a person may need 30-plants for back-pain – but what if that is what it takes? Are you seriously going to limit a medical patient from his or her right to self-medicate with whatever works for them?
