you can turn CBD isolate powder (cheap) into primarily delta-8-THC and some delta-9-THC (the THC we all know and love) by heating it with zeolite clinoptolite powder (also dirt cheap) - an FDA food safe “supplement” used for metal detox or some gay hippy shit. dont believe me? google it. learn some basic chemistry (i was doing this shit on the hob and in my oven, i’m not a chemist) and been high as shit for years daily.
