Drugs used in medicine are routinely given what is called LD-50. The LD-50 rating indicates at what dosage 50% of test animals receiving a drug will die as a result of drug-induced toxicity. A number of researchers have attempted to determine marijuana’s LD-50 rating in test animals, without success. Simply stated, researchers have been unable to give animals enough marijuana to induce death.
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 g. A smoker would theoretically have to consume nearly 1500 pounds of marijuana within about 15 minutes to induce a lethal response.
In practical terms, marijuana cannot induce a lethal response as a result of drug-related toxicity. Even if someone is smoking marijuana concentrates or dabs which can be 3 to 4 times more potent than their flower counterparts, that’s still hundreds of pounds of marijuana dabs within a 15 minute period. A person would pass out before they experienced a lethal dose of marijuana. Something could harm the person if they fell while passing out resulting in death, but that’s different than the marijuana itself causing death.
