I am partially playing Devil's Advocate here as I do not in any way shape or form recommend the use of LSD. To my knowledge no one has even posted any reliable source that can support a beneficial use of LSD. The link that came under fire was a "Mushroom" link, not LSD. My claim was that there has been at least one study done where controlled use of Psilocybin has shown potentially beneficial effects. I'd be interested in seeing a counter argument outlining how negative psilocybin can be.
