Anyone out there tried any of those? Spirit Walk is supposed to be like shrooms (and supposedly is under review for scheduling in the USA). Crystal...duh is supposed to be like speed. Snurf is supposed to be like E. Any info on these would be grateful. Also a lot of these websites that promote those advertise them as being like this or that and compare them to illegal drugs, some even have 'testimonials' that compare them to other drugs, is this legal?
