That's not true. A Volcano is the closest vaporizer to one that does no harm, but those are expensive as hell. Vaporizers varry depending on their quality, eliminating combustion-created carcinogens by anywhere from 25% - 98%. And even so, there are still SOME carcinogens in weed that are not created from combustion, but they're in very small quantities.
