I've smoked salvia before. Actually a few times. For me the trip is always very unearthing, but afterwards I'm always wanting to go back to get more "answers" out of the trip. Its very hard to describe what it feels like. The proper way to smoke salvia is out of a bong using a torch lighter. You have to smoke it FAST and the heat has to be extremely intense to activate the salvinorin-A thats responsible for the high. I smoked a 15x extract and I tripped HARD.
I had done a lot of research on erowid before trying salvia so I half knew what to expect. I did it alone in a dark, quiet, comfortable room. I smoked and then sat back with my eyes closed. I remember starting to feel the effects settle in, and then talking to my friend (who wasn't even there) saying that I feel it but I'm not tripping. Then I looked to my left and saw large X that appeared to be made out of a bright orange lightning. I tried to tell my friend (not there) that I was starting to trip but couldn't finish my sentence. All of a sudden I started tripping hard, I stood up and when I moved I felt as if I was moving in between dimensions. I had this profound realization that everything in life was fake, and that all of my friends, all of the world, and that everything I had ever done was just a dream, and that I was just now waking up in my real life. Everything in my view was in 2D, and I could see what appeared to be 2 different dimensions side by side, and by moving to the right I was warping into what I believed was the real world, and then when I moved to the left I felt as if I was coming back to this world. A little while later the trip ended. I sat back down and just sat there for a good 15 minutes just trying to make sense of everything. It made me question everything around me...I walked around in my apartment looking at everything...it felt as if I had just come home after not being here for a good year or 2. Everything looked unfamiliar but I knew that it was mine. Salvia is extremely intense if done right. Out of a 1 gram baggy of the 15x extract I got enough to trip about 5 times, each time the trip was different but just as profound.
