My advice on the matter is make DMT. Check erowid or dmt-nexus. Mimosa hostilis root bark can be bought on ebay for well, say 50$ for 250 grams of the stuff. Other herbs also work. From 30 grams, a good chemist (not necessarily) can extract 5-6 hits. From what i remember you will need:
Sodium hydroxide (drain cleaner)
Naphta (lighter fluid) or ether, chloroform etc...
Funnel, filter paper, jar, turkey baster.
PH papers or Digital PH meter
Say, less than 10 hours of your time along with 2-3 weeks of waiting.
Also there are 2 extractions, straight to base and acid to base extraction. Both work STB is easier.
And the other alternatives are, well depends on your climate i guess but many are listed: Cacti, Kratom, Salvia etc etc
When I made it, it worked wonders!!
