oh ya one more thing... the burnout for smoking is far more harsh than the burnout from vaporizing, and u dont have that dirty feeling associated with the smoke chemicals entering your body. after vaporizing i still feel completely clean, but not when i smoke, i feel dirty.. everyone that i have heard of that makes the switch mentions that word 'clean' and its not just because the stone is pure, but that is also because your body actually feels clean.. funny how that works
