Make sure you're using proper technique. Use a torch lighter and never inhale regular air inbetween your salvia hits. NEVA-EVA. Always make sure its hit after hit. 3 hits of 20x and you aren't flying? Damn... either your salvia is shit, my salvia is DA SHIT, or your a true salvia hard-head. ^.^ 1 hit of 20x does me up proper for a nice class 3 high.
