I've seen the term quite a bit, Erowid doesn't point to DOx specifically, but rather to derivatives like DOB, DOI etc etc...Are these basically synthetic phenethylamines or is it something else? LSD is a synthetic tryptamine, right? So is phenethylamine a different type of neurotransmitter? Do all of these chemicals, tryptamine, phenethylamine, etc occur naturally in the brain, and consuming drugs with these as active ingredients just increases their presence? DMT is a naturally occuring hallucinogen secreted by the brain, correct?
