Weed, Ecstacy, shrooms, acid, speed (digested, snorted and smoked), mdma, salvia, payote, mescaline, Ketamine, Khat, and Coke. (i really have tried these, in some cases many many times over)
Cant actually think of any others. Stayed away from the dirty stuff such as mandrax, heroin etc...
But ya, all of the above from Trance Parties, havent touch hard drugs in about 2 years now.. past that stage in my life. I regret nothing though, it was absolutly awesome to experience all of the above.
