Vaporization is an alternative to burning (smoking) which avoids the production of irritating, toxic, and carcinogenic by-products by heating the material so its active compounds boil off into a vapor.

Vapor ideally contains virtually zero particulate matter or tar, and significantly lower concentrations of noxious gases such as carbon monoxide

  Vaporizers contain various forms of extraction chambers including straight bore, venturi or sequential venturi.   Read more »
