.DMT extraction
.Mushroom Teks (there's some tutorials others have already posted, just copy them)
.Maybe some LSD info; dosages, different forms it comes in (blotter, liquid...)
.Definitely one about MDMA and the harms/ risk with RCs. Maybe throw in some info about the test kits, how they work and why people need to use them
.Other extraction teks; mescaline, peyote, aya...
.Pill info (although there's kind of a lot of info on these, so idk how or what to narrow it down to)
.Why you shouldn't do heroin...
these seem to be the most common
