Good article, I would like to add my personal experience I tried Salvia and had a really bad trip,I was with some friends and they were too descriing awful things and hurtful, and we were surrounded by trees and beautiful things but with Salvia everthing is distorted.
I felt like my arms had some kind of evil , a really physical experience , it almost made me lose my mind. I dont recommend to use this to anyone, this thing can drive you insane , be careful.
