Psilocybin ponies

Governments tend to disproportionate responses to publicly visible events. As the father of a 17-year-old myself, I feel for the Dutch girl's family, but bringing prohibition to magic mushrooms because of a single death that can't even fairly be ascribed to the mushrooms suggests the convenient use of her suicide to enact a policy that the government already wanted to enact. (Remind you of anything?)

Wikipedia claims that the LD50 of caffeine is lower in rats than the LD50 of psilocybin.
