A classmate of mine takes it regularly and says it's stronger than weed. They sell it in shops downtown actually, I just never got around to trying some based on my previous wildflower drug experience when I took quite a large dosage of
Datura Stramonium. I don't plan on trying salvia anytime soon.
What I do fancy now is
Diphenhydramine. It's in many stronger allergy-reducing pills. It is a hallucenagent, but I haven't taken it in that quantity yet because they can bother your stomach at higher doses.
You should check out
erowid.org if you're into that stuff. But READ WELL because a lot of that stuff can be really dangerous!
