theres several drug harm mitigation sites anon, read into it. psychonauts is a good resource for most info on pretty much all drugs.  and from personal experience. i keep my doses at 30-50mg. i take it once a month, for over 15 years. no iq reduction, no memory issues, no depression. if anything i think its one of the reasons i never got depressed.  i do mix it with other things time to time. never go above 60mg though.  again. most studies were honestly done in a way that anything would be harmful. mega doses, over days, no recovery. no proper care, no hydration, just animal abuse outright.
