I personally don't feel much compulsion to keep trying new drugs at all. I am curious, but can certainly live without RC's. Everytime I take mushrooms I experience something completely different- theres enough variety in the natural world (who, if you know her well enough, won't rip you off ever) to satisfy me. I prefer to not contribute to anyones pocket if I can help it when buying or obtaining drugs- because when money is involved, so is lying, cheating, stealing and fakery. Call me paranoid, but I don't think anyone can KNOW what their taking unless they are able to analyse via GC/MS. Truly.
Im not sure why people think RC sellers are some kind of saint or giving a gift to the world, that baffles me. I don't think their motives are as pure as we'd like. I see no evidence to suggest that these people are doing anything except selling drugs, kinda like bikies sell methamp in Australia. Rarely is much of a warning about effects provided, IME, and often people simply don't care enough to bother. RC's (YES i HATE THE NAME) actually have caused me more problems then good- I want LSD when I buy that, not some other chemical that I don't want. But I still may receive it.
I understand the drug collecting thing- though I suggest it is purely an egotistical, materialist thing. As said, they are just molecules- their matter is irrelevant compared to their effects. I will say to anyone that has mammmoth amounts of drugs they aren't going to use to share

Otherwise, its like being a Rupert Murdoch, but with drugs not money. Or something.
