Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog ran from 2006 to 2016 and was intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    The Volcano alternative means of delivery of inhaled Cannabis sativa

    An earlier study (reported here, discussed here) showed that the Volcano vaporization device is a reliable way to achieve lung concentrations of marijuana.

    Now, researchers from the University of California and San Francisco General Hospital confirm that vaporization of cannabis is a safe and effective mode of delivery of tetrahydrocannabinol (THC). They think the device should be used in future studies of THC.

    First, the details.

    • 18 healthy people were enrolled for 6 days of treatment.
    • The delivery of cannabinoids (3 different doses) by vaporization vs marijuana smoked in a standard cigarette was compared.

    And, the results.

    • Peak THC blood levels and the amount of THC absorbed (6-hour area under the plasma concentration-time curve) were similar.
    • Carbon monoxide levels were reduced with vaporization.
    • No side effects occurred.

    The bottom line?
    The researchers conclude that vaporization of cannabis is a safe and effective way to administer THC. The THC reaches the blood stream, but the harmful effects of carbon monoxide on the lung are avoided.
