Of course, I have no idea why someone would use the Volcano to smoke illegal herbal products, especially when so many quality pharmaceutical medicines are available, according to my Tee-Vee.

Two new studies, one from the University of California, San Francisco, and the other from the University at Albany, State University of New York, provide strong evidence that technology now allows medical use of marijuana with the rapid action and easy dose adjustment of inhalation, but without the respiratory hazards associated with smoking. This is considered highly important, as the risks associated with smoke inhalation have been cited by both government officials and independent experts as a major argument against medical marijuana.
The San Francisco study, conducted by Dr. Donald Abrams and colleagues at UCSF and just published online by the journal Clinical Pharmacology and Therapeutics, compared a commercially available vaporizer called the Volcano to smoking in 18 volunteers. The subjects inhaled three different strengths of marijuana either as smoked cigarettes or vaporized using the Volcano. Unlike smoking, a vaporizer does not burn the plant material, but heats it just to the point at which THC and the other active components, called cannabinoids, vaporize. The vapors are collected in a detachable plastic bag with a mouthpiece for inhalation. The researchers then measured the volunteers' plasma THC levels and the amount of expired carbon monoxide (CO), which is considered a reliable marker for the unwanted combustion products contained in smoke
The Earleywine study is available online at www.harmreductionjournal.com/content/pdf/1477-7517-4-11.pdf. Copies of the Abrams study are available by e-mail from MPP director of communications Bruce Mirken, Bruce at mpp.org or 415-668-640
