Yo man, the first time I tried Salvia was in my boy's dorm room. It was 20x extract and he packed a fat ass bowl. After two heads clearedthe bowl quickly , I didn't feel much, so he packed another bowl (big mistake). After hitting the bowl again, I was go messed up that I fell out of the chair and began to laugh hysterically. Then I bugged out and shit started to spin. I tripped for a good 15 minutes. The moral of the story is there is absolutely no reason to smoke a blunt or even a joint packed with Salvia, all it takes is a nice bowl and you'll trip.
