great link, ermitonto... Very informative, even though I wouldn't touch that crap with a 10 foot pole (not that I ever have anyway)

But, if you wanna get high legally, go with Salvia. I've never tried it personally, but I heard it's a pretty intense high which lasts for about 30 minutes max, then you're all relaxed and shit. They sell it at my local headshop, 10x and 20x extracts. If there's a head shop near where you live, ask them about it, they might have some.
