Marijuana Vaporizer

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 .

More than a dozen manufacturers have sprung up to churn out the devices in the San Francisco Bay Area. But federal officials aren't fired up about the vaporizers -- or the fact that they still deliver an illegal drug.
