NONE........
i think its nearly 7 a day
Yeah, no concern how much pot you smoke, you can't overdose.
Its virtually impossible from a direct result of marijuana, unless you smoke literally a tonne of it, but youd pass out previously you could die, but im sure lots of people hold died from doing stupid things when theyre wacked like driving or self hit by a car or accidently starting a fire or something approaching that.
I have never see or heard anything that clearly proves that anyone have died as a direct result of smoking marijuana
