Salvia is some real shit. The concentration/potency of it is dermined by how man "x" it is. The first time I smoked 10x shit mixed with some weed, and had a very pleasnt trip in a park, where I somehow thought I was communicating with a flock of ducks by this pond. All the colors were very intense too.
A few years later I smoked a huge hit of 80x shit while I was at a Zakk Wylde concert. Nothing prepared me for that. I litterally had an out of body experience, my friend said I was leaned over the seat in front of me drooling. But in my head I was having some weird conversation with aliens or some sort of intelligent beings not from our dimention. They told me that I could leave this world and know the "truth" but I could never go back and would have to leave all my friends and family behind. While I was contemplating this, Zakk started shredding this solo, and the notes were shoooting out in beams, and I grabed onto one like a rope, and it sort of reeled me back into reality.
