I've had some very light experiences on salvia that were interesting. I have a 40x extract, my buddy gave it to me. He smoked it a few times, he said a tiny sprinkling on the top of a bowl cause him to have the most intense and unsettling experiences of his life, bar none. He did it 4 times. He said afterwards he has always questioned the nature of reality more than he ever has before, and that he will probably never go back because it was too disturbing. But incredibly fascinating.
But yeah, I would like to try the quid method, I hear it is much different and more entheogenic and not so insane. Traditionally it was used as a quid, and not smoked.
