Excerpted from a 1988 Department of Justice/DEA brief written by Judge Francis L. Young:

“In layman terms this means that in order to induce death, a marijuana smoker would have to consume 20,000 to 40,000 times as much marijuana as is contained in one marijuana cigarette. NIDA-supplied marijuana cigarettes weigh approximately .9 grams. A smoker would theoretically have to consume nearly 1,500 pounds of marijuana within about fifteen minutes to induce a lethal response.”

You would have to CONSUME (as in eat) & You would most likely die from how much cannabis youve eaten rather than how much thc goes into your system . Only so much can be absorbed before you "cant get high " thus dying from eating 1,500 pounds of plant matter in a short period of time. Remember too much water can kill you too!!
