Does anyone have real data on the LD50 (median lethal dose) for LSD in primates or something more similar to humans than rats? ...I find it nearly impossible to find any good hard data on this, and considering that the substance was once researched even by the military, there should be some data somewhere.
...and no, you can't compare LD50 for iv injected LSD with injested or mouth-absorbed LSD, there might be very different pharmacokinetics and the deaths from injected doses might be a "reflex" heart stop or some other preventable cardiovascular side-effect.
