I was thinking the same about vaporizers. It was cool and everything, but there was "something" missing. Then we took it to friends who live up in the mountains. These are some pipe- hittin motherfuckers. They didn't like it because there was no smoke. Literally. That they didn't feel smoke in their lungs, so it took something away from the experience. I wonder if the same is why e- cigs haven't really caught on.

Cheaper, no smell, no smoke, you can smoke iside. A product like this should change the world. But it hasn't. And that kind of fascinates me.
