I am new to this board and I have ben reading the methods of use section alot, and I see allot of people talkign about theese vaporizers.

What exactly are they. I went to a few online head shops and it looks like some sort electric thing, with a bowl on a platform and a galss jar to go over it. Then has a hose coming out like a hooka. Does it just heat up the weed? Does it make smoke?
Does it not smoke up a room and smell like you have ben smoking? how does it work?

I am just curious I have ben smoking for a couple years and have ben around it for awile but have never heard of theese things, or seen them in head shops. (well i guess I could have seen one and not known what it was)

Any light you could shes on this would be great!
