Not from what I've heard....a friend was being treated for Cancer and couldn't eat, loosing weight rapidly, his family members had stated if they had to they'd take him to Canada for "weed".... for the pain and in order to stimulate his appetite.
It does stimulate appetite...

Caww, keep reading down his post. I believe Vigilanteman was just having some fun by being sarcastic. I hope your friend recovered.
