At present it is estimated that marijuana's LD-50 is around 1:20,000 or 1:40,000. 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.
In practical terms, marijuana cannot induce a lethal response as a result of drug-related toxicity.

I was waiting for someone to blurt out that kind of clap-trap, about how harmless marijuana is as a habit!
