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.”

Compare and contrast the damage that just two bottles of tequila would do to the human body (Been there, done that and won the booby prize of 4-day hangover...).

And while I’m on the topic, whereas you can see that it’s impossible for a human to OD on cannabis, the plant is HIGHLY toxic to dogs. That’s right, do not let your pooch near your stash. If you make pot brownies keep them out of your dog’s reach (Chocolate is also lethal to dogs. So are grapes and onions). If your dog eats cannabis, rush it to a pet hospital without hesitation.
