Not realy toxic !

Cannabis has been used to treat pain and other ailments for at least 5,000 years, from ancient China to Victorian England.In the USA, it was a battlefield painkiller during the Civil War and was added to patent medicines until the turn of the century.But whether marijuana is a safe  drug by modern American standards is the subject of growing debate in the medical community. No one has ever died of THC poisoning, mostly because a 160-lb. person would have to smoke Over 1000 joints in a sitting say 30 mins to reach a lethal dose.not realy toxic then.
