The evidence for that is incredibly slight and for very limited circumstances only. There are plenty of clinically-trialled, mainstream medications that are way above CBD in the epilepsy pecking order. I won't respond to the rest of the idiocy in that post.

What I strongly suspect from some of the posts in this thread is that there are people who like using cannabis for recreational use who are trying valiantly to legitimise it (and themselves) by claiming medical efficacy on top. For any serious condition I have or have had, my resort is to mainstream, trialled medicines. My wife was involved in two back-to-back clinical trials for two drugs aimed at preventing breast cancer. Two back-to-back, five-year trials and long-term monitoring thereafter. Both were double-blind trials which involved thousands of women. That's how it's done and how it should be done. Any claims here as to the efficacy of cannabis or its extracts simply can't hold a candle to that. Which is not to say that there isn't something in them. That isn't what I'm saying.
