I've been in the cannabis culture for over 30 years and I've never known anyone to have any health complications that could be described as caused by cannabis use.
Do any of you other forum members have first hand knowledge of any health complications that can be attributed to marijuana use?
My point though is that even if it were dangerous - even really, really dangerous to the user, I still think the user should have the option of making his own risk-benefit anaylsis and choosing whatever they feel is best for them. everyone knows tobacco is dangerous to the user, yet most people believe that people should have the option of making the decision for themselves whether or not to smoke. I think the same should go for any substance.
