Pot, LSD, PCP, 5-MeO-DMT, PC-Duster (I think it's Nitrous Oxide or Freon or some shit, whatever it is I can't do it anymore,) Salvia (which did nothing for me,) Valium, Soma, Anti-depressants (can't remember the brand.)

Also alcohol and cigars if you consider them. I'm also probably leaving something out.

I don't do anything now except alcohol occasionally.
