"No, that isn't true. Natural vs Synthetics is a major difference. Naturals ARE more known about even than synthetics because there is almost always only one active ingredient in organics. Also, neither THC or Psilocybin will cause overdose. Period."
Yeah, okay. If you were truly on the "natural" bandwagon, you'd realize that one of their main arguments is that naturally occuring drugs are a BLEND of many different active components- when synthetically made, the blend is not reproduced, but simply an isolation of the most active component.
Read about Marinol.
Oh, and while you are at it, read about the mescal bean, and fly agaric - one is a sacred bean used by Native Americans, and which, if more than 1-4-13rd of it is eaten, the delirium will so overpower you that you won't know what to do with yourself. The other is a mushroom used by native Americans - yes, the classic read toadstool with white spots - and will cause the same delirousness.
Now, how is this any different from the supposed danger experienced by the PCP idiot above?
