I've smoked Salvia several times but only once have I experienced level 5 intensity. I was in another dimension, being laid as cellular brick on what would eventually appear as another human being. My roommate reached out to me and stacked me ontop of myself again and again. That was on a whole bunch of 40x that was preloaded in seperate bongs. I attribute my good trip to the music that was playing and the multiple bong preparation, a setup which had allowed me to hit as much as possible before things turned squeaky.
