I've been growing san pedro for years. And psilocybe mushrooms. I've had a stash of mimosa hostilis for a while now. Pure DMT is an intense experience. It's so intense that I'd recommend things like shrooms / mescaline / acid before DMT for newbies to psychedelics. DMT before other psychedelics is like learning how to skydive before you learn how to walk.
Everyone's talking about different teas, but the actual tea plant is awesome. Tea is probably my second favorite plant. If you aren't a tea believer, get some good green or white tea from an Asian market. Brew a strong cup, drink it, and see if you change your mind.
