That's dope: Marijuana vaporizer without the smoke
A new gizmo could soon become a popular accessory for medical marijuana users. The vaporizer lets users inhale the drug, without smoking.
One version looks like a metallic volcano and sells for more than 500 dollars. Its creator calls it "the Mercedes-Benz of vaporizers." Advocates say that by heating marijuana to a point where vapors are formed but before combustion, a vaporizer is free of many of the toxins and harshness found in marijuana smoke .
