how much marijuana would a person have to smoke to die?!

I have heard a couple of stats on that from the history channel, or discovery or something. The first one was that you'd have to smoke like 500 pounds of weed in 15 minutes to die, and the other one said that the amount of weed it takes to kill a lab rat is 50 pounds, dropped from 100 feet in the air. Lol. So basically, it's impossible

My noodle

if the smoker has wpw acardiac condition ,known as white parkinsons wolf syndrome a couple of tokes could spark an episode of rapid heart beating that could cause serious supraventricular tachycardias such as atrial fibrillation or atrial flutter or even worse flutter fibrillation . these arhythmias comprmize cardiac output and sometimes decompansate into ventricular fibrillation followed by death.. rj
