At raves I have seen or taken MDxx, Speed (meth and prescription), coke (rair, but I have seen it, mostly at renegade/underground/house parties), benzos (mostly xanax but some others), lots and lots and lots of ketamine (big thing around here), booze, opiates (mostly oxy, but some others, ocaisonally heroin), weed, 2ci, 2cb, 2ce, amt, ghb, lsd, lsa, mushrooms, and dmt...maybe some others too, but that seems to be pretty complete...so in other words, pretty much any drug you can find. most common around here are K, Molly (some pressies, but mostly molly around here), booze, and acid.
