A vaporizer is a technical process requiring technical equipment at which most of what is offered in the market place as a vaporizer is a rip off,.... a vaporizers purpose is to heat the hemp to the vaporization temp and maintain it regardless of the air speed drawn across the herb, and it is healthy because no smoke is present, its a very clean high because ones body is not full of toxic waste in the blood stream generating that dirty haze feel, like you are high on smog... the AroMed is the best vaporizer I have found, nothing comes close, not even the valcano... although the valcano is better than the vapir, the AroMed is easily better than the valcano... VAPE ON!
