Use a groovetube if you're worried about the smell. Those work when you're smoking it in a bowl extremely well. Most vaporizers are shit though. For some reason they just don't work. The only vaporizer I know for sure to be good is the Volcano Vaporizer. And that bitch costs like 500 bucks. Then again it makes it so that about half a gram of weed gets 20 people blitzed out of their minds.
