Psilocybin was promoted by an ex Public Relations CEO of JP Morgan who also happened to be a member of the Council of Foreign relations (Gordon Wasson). It came out that his Russian wife was actually a double spy. Also it came out that another character of JP Morgan around 1840, already was doing some research with psilocybin mushrooms. What exactly do they mean when they say 'Gordon Wasson discovered magic mushrooms'.... And this is only the tip of the psychedelic iceberg (search leary cia, pm me for some amazing breadcrumbs). If someone like that wants you to take psilocybin, you better assume it is meant to hurt you. Maybe not now, but in the long run. It doesn't have to be physical damage, it can be mental, bringing you to a sleep of a whole new level but still, deep asleep. And while you are sleeping, you are convinced that you are so much more awake than the rest of the profane. Don't take my word for it, research for yourself. You can only understand the present and the future by studying the past.
Don't take your history lessons from Terence Mckenna, he won't tell you the really fascinating things but only just enough to keep you going around in circles while planting the suggestion that you are actually learning anything instead of being led around in circles for years and years. When Mckenna talks about Huxley and/or Darwin, he leaves out the real interesting historic stuff. Stuff that he must have been aware of but for some reason, left out of his all his work. He (and mushrooms), had me by the balls for almost two decades. That's almost two decades of following bullshit and propagating that bullshit to everybody who wanted to hear (and everybody who didn't want to hear).
I know nobody wants to hear it, I would have dismissed it as bogus myself only six months ago.
