I'm glad you have a place to vent and certainly understand your feelings.
From all I have read, I think withdrawl from pot can be difficult...I've heard it takes over a month to just get out of the system, never mind coping with all the addictive issues. The other scary part to me is that pot is so often laced with other things and who knows what a person is smoking. Addiction is addiction in my book and its impact on loved ones is equally devastating no matter the doc. Hugs.
