there is so much misinformation in this thread. Yes a vape conserves weed but only because smoking it destroys at least 50% of the active ingredient upon combustion. When smoking, you also inhale everything else that you put in the bowl (ie. vegetable matter). When vaping, you inhale all the goodies and none of the bad stuff. Also, I have a whip/box style iVape and it holds as much as a standard bowl for a bong. I get more hits out of it and it gets me higher and without all the harshness of smoking. I literally cannot smoke anymore after owning a vape for a few months. I've never used a bag vape but it sounds like fun. I hear people talking about how they only vape once in a bag or whatever but I vape my fucking bowl till all the goodies are milked. I don't know why someone would only smoke half a bowl...vape what you put in the fucking bowl until its done :stoned:
