If you like the trips of Salvia I highly, highly recommend the 20x. I smoked a little of the 5x and jumped straight to 20x. The trip was so intense it was weeks before I got the balls to do it again. I mean the stuff was legal, so I thought " how bad could it be?". Ohhhh, shit was I wrong.

As for your friend not getting much of a buzz, my friend Nick was the same way, except he was completely uneffected. It all depends on your body chemistry, too bad so sad for him =)
