Guy probably laughed himself to a heart attack or something.

I thought it was a little more dumbed-down than it needed to be. I don't remember them even defining their terms: Does "dangerous" mean to the individual who uses it, or to society as a whole? Since tobacco kills so many thousands a year and yet is lower on the list than Ketamine, which kills one, I have to assume the "danger" they are quantifying is to the individual. Yet the documentary consistently addresses the issue of popular perception as propagated by the government and the media, which would indicate that they are looking at drugs as a societal phenomenon, not an individual one, and really, shouldn't the voting/taxpaying/television-watching public be more concerned with that latter definition of "dangerous"? I mean, if Ketamine is higher than Tobacco even though it kills only one person a year, "...because at high doses, it can result in heart failure, and even stop breathing", then shouldn't, say, gasoline, be even higher on the list, since I'm guessing it is even a better guarantor of death than Ketamine, for anyone that decides to consume it?

Good eye.

With Psilocybin, a lethal dose is around 250 times the so-called recreational one, while studies suggest that the LSD ratio seems to be ? (infinity). There is no dosage of LSD that will make your body stop functioning.

Curious how in the hallucinogenic realm, the higher it gets you, the less toxic it is.

Consider Di-Methyl Tryptamine, also known as DMT, extract of the ayahuasca plant. It seems to be the single most powerful hallucinogen known, yet not a trace of it remains in the human body within an hour of having smoked it. This most intense of highs, which reportedly has astonished even the most jaded of psychonauts during their first dosage, lasts less than 10 minutes!

I have read anecdotal reports of DMT starting to make the rounds in Mexico City, at US$50ºº a pop.
