i bought some salvia divorium a while ago. You need to use a butaine lighter. the leaves from the salvia need to be at a certain temp to combust nd release the chemical the fucks u up. if i were u i would buy an extract like 5x or 10x to really trip, i think they make up to 25x. salvia is suposed to be pretty intense, if u get a strong extract be sure to have a sitter. the high usually only lasts 30 mins soo if u have a bad trip it shouldnt be for too long. when u doo salvia u should be in a dark and quiet environment, i think like tv can cause a bad trip but im not too sure.
