   Leiden, the Netherlands: Vaporization is a "safe and effective" cannabinoid delivery system for patients desiring the rapid onset of action associated with inhalation, but who are seeking to avoid the respiratory risks of smoking, according to clinical trial data to be published in the Journal of Pharmaceutical Sciences.
Researchers at Leiden University's Institute of Biology (the Netherlands) found that use of the Volcano vaporizing device delivered set doses of THC to subjects in a reproducible manner while suppressing the intake of respiratory toxins.
"Our results show that with the Volcano, a safe and effective cannabinoid delivery system seems to be available to patients," investigators concluded. "The final pulmonal uptake of THC is comparable to the smoking of cannabis, while avoiding the respiratory disadvantages of smoking."
Cannabis smoke contains many of the same carcinogens as tobacco smoke, including greater concentrations of certain aromatic hydrocarbons such as benzopyrene, prompting concerns that chronic marijuana inhalation may be a risk factor for tobacco-use related cancers.

"These data confirm that vaporization can deliver all the essential components of medical marijuana safely and effectively while suppressing the intake of carcinogenic smoke. Now the Drug Czar's office and the Food and Drug Administration can rest assured that patients may receive the therapeutic relief they need without suffering from the unwanted health risks associated with smoking."
