My first salvia was 10x extract smoked through a pipe. It was surreal but thouroughly enjoyable. The last time I used it I was at my computer with 15x, and unwaringly drew a picture in MS paint. All I can recall of it was I felt like I was sucked into the computer screen, and that y hand moved to the pattern that I could feel. If that makes any sense. For those that are interested I'll upload the file.
