Ummm....that sounds like a load of crap. From what ive come to understand salvinorin a is a powerful seretonal inhibitor and hallucinagenic replacement. Science barely knows anything about the drug and has no idea how it affects the brain. They do know that it leaves no lasting affect after it's use besides the profound memory of it's effects. If you hear anything about how salvia works, just be safe and don't believe it because there isn't much research going on about the plant at all short of growers trying to increase potency. Just do your research, like I know this kid that keeps on telling people that the reason that you trip out on LSD is because your brain bleeds and the pressure of the bleeding causes hallucinations. See modern american drug culture is full of 90% bullshit.
