I discovered salivia a few years back when they were selling it at the porn shop I worked at. I got some of my friends hooked on it and word spread really fast, as time went by more and more kids would come into the smut shop to buy it (well, not KIDS, but comparitively to the dudes who normally came in). I dont know a lot about it, but we sold different kinds: 5x, 10x, 20x. The higher the number the more potent it was. Anyone that didnt have a absolutely fucked up experience on salvia must have only had the 5x. When it's strong enough, it hits you right away, like right as you're exhaling and then suddenly you dont know where you are or what you're even doing, youre just gone. In my experience, I just remember my peripheral getting dark and then everything I was looking at just broke off into geometric shapes and moved around like a kaleidoscope (I've done shrooms several times and I never get visuals). I felt like I was falling or being pulled down the whole time and I remember just hearing weird chanting/music in my head. It's very intense, but doesnt last very long, maybe 10 minutes. For a while I really got a kick out of getting as many my friends to try it as I could. Watching someone trip out on salvia for the first time is awesome. They never realize what they're getting themselves into.
Now whenever I visit my old porno stomping grounds they're almost always sold out of the 20x salivia. It's amazing that the shit is legal, let alone packaged without any warnings. It's a lawsuit waiting to happen.
