How does it work, anyway?
The general principle is much like distillation. THC vaporizes at about 160C, which is well below the burning point of the marijuana. So vaporizing is basically boiling the THC off the weed without setting it on fire. That way you're just inhaling water vapor and THC without the smoke that you'd be consuming from the burning weed and rolling paper if you smoked it.
Essentially, you have a device that heats up. You put the weed into a chamber and you suck on it. You draw heated air over the pot and the hot air vaporizes the THC. You inhale the air, THC and water vapor. No smoke, since the weed isn't burning. The THC is just being "distilled" off the ground weed.
