Nope. It does not. Read what Chocoloco posted. There has never been a recorded case of someone ODing from marijuana. Alcohol is more dangerous in this regard.
Not going by 2009 numbers. (Chocoloco's source admits to a copyright 2008.) Per DAWN's fact sheets, more people had emergency visits than from alcohol alone. (Alcohol, when mixed with other things, has a higher number summated, but part of that is attributable to interactions.) In fact, in 2009, the only solo-use drug with more emergency visits was cocaine.
It's not as "safe" a drug as people are trying to make it out to be...
Sorry Dunno, I have more information. I will say that the potency of the THC in the experiments mentioned were relatively low, but your not going to win an arguement against this considering I have done a lot of research on marijuana in college and even took a class on cannabis at my university. Just knowing about the drug is a great interest of mine since I care more about legalizing the drug than actually using it myself.
According to which US Government authority you want to believe, the lethal dose of marijuana is either about one-third your body weight, or about 1,500 pounds, consumed all at once.
The non-fatal consumption of 3000 mg/kg A THC by the dog and monkey would be comparable to a 154-pound human eating approximately 46 pounds (21 kilograms) of 1%-marihuana or 10 pounds of 5% hashish at one time. In addition, 92 mg/kg THC intravenously produced no fatalities in monkeys. These doses would be comparable to a 154-pound human smoking at one time almost three pounds (1.28 kg) of 1%-marihuana or 250,000 times the usual smoked dose and over a million times the minimal effective dose assuming 50% destruction of the THC by smoking.
4. Nearly all medicines have toxic, potentially lethal
effects. But marijuana is not such a substance. There is no record in
the extensive medical literature describing a proven, documented
