I am sick of hearing about serotonin from that damned erowid kid! All he does is talk about brains and tripping!
A neo-hippie technophile that is obsessed with psychedelics. You can typically find these people sitting on the couches at the back of a rave club trying to talk about politics, life and philosophy... they will usually either yell at the top of their lungs, sit on top of each other, or just stair at each other trying to communicate telepathically.
Those raver hippies in the back always have acid and ketamine!
A class of indole alkaloid drugs/chemicals, many of which are psychoactive. Tryptamines are typically serotonin-affecting psychedelics/hallucinogens. Detailed information about Tryptamines can be found in the book TiHKAL, or 'Tryptamines I have known and loved' by chemist Alexander Shulgin. Some popular tryptamines include LSD, DMT and Psilocybin (the active ingredient of psychedelic mushrooms).
I am the master of tripping! I vow that I shall one day have consumed every tryptamine in existence!
