I have a box vaporizer, the VaporTower. I'm not sure if what I'm inhaling is actually vapor, or a mix of vapor and smoke, or just smoke. I know I get a lot of air along with the smoke/vapor. The hits seem to reach pretty deep in the lungs because I cough a lot, even more than I do from smoking. The spent weed isn't charred, it's just brownish green, so I guess I'm not burning it... and my throat is never sore after vaping, as it is after smoking. But it does seem to really choke me up. It makes sense that it wouldn't irritate the throat as much because when using a vaporizer it seems like the vapor/smoke is dilluted by all the air you suck in through the tube. I guess I'm just not convinced that this box and tube vaporizer is actually vaporizing the weed and not just burning it really slowly. Ever since I started vaping I've had dark circles and been noticing new fine lines under my eyes. I just have this feeling that this vaporizer is actually doing me more harm that smoking blunts, maybe I'm just being paranoid. Is it realistic to be getting pure vapor out of a $200 box vaporizer?
