By overdose I mean you cannot take a lethal dosage. You would have to smoke 1000 joints in under one minute to get the same effect you do in 24 hours of consuming alcohol. However, smoking pot and drinking alcohol at the same time will multiple the effect of both pot and alcohol which will act like an overdose. (Believe me, I've tried, and it's not pretty).
I smoke it to relieve anxiety, before I go to bed at night. And it works.
I smoke once a month, once every two months, (now it's been over 6 months since last time).
I would much rather sit in a room filled with stupid ass pot smokers than a room filled with alcoholics. Why? Because people on alcohol are prone to become violent over a mere cookie, pot smokers aren't.
Go look for "Death by pot" or "Crime on pot," I bet you won't find anything.
Ps. You shouldn't abuse any substance.
