Exactly what I was gonna say. It might not have even been an OD, just a reaction. Some people are allergic or have a strange reaction to pot when they smoke it. That is a likely culprit in this case.
it says in the article, that the dood smoked like 6jays/day. i think he would have presented some kind of allergic reaction at some point before.
i was just looking around, and i found this quote, from the dea (hold your breath, its a bit surprising considering the source).
"Marijuana, in its natural form, is one of the safest therapeutically active substances known to man.... At present it is estimated that marijuana's LD-50 is around 1:20,000 or 1:40,000. In layman's terms... a smoker would theoretically have to consume 20,000 to 40,000 times as much marijuana as is contained in one marijuana cigarette... nearly 1500 pounds of marijuana within about fifteen minutes to induce a lethal response." [In the Matter of Marijuana Rescheduling Petition, U.S. Dept. of Justice, DEA, Docket No. 86-22, Sept. 6, 1988 (Young, J.). Back in '88, some member of the dea, or something, actually suggested reclassifying pot. the quote mentioned summarizes some of the points, which if you review the full text, are backed by medical evidence. the drug czar denied the attempt.]
seems i was underestimating the ld50. i don't know what about marijuana would mean that the supposed 20000x dose would have to be within fifteen minutes, but it makes it seem a lot less likely. and there i was trying to take an article at face value. that'll learn me. cool to see most everybody finds fault in the article.
