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!
