Albany, NY: The inhalation of cannabis via a vaporizer reduces pulmonary risks associated with smoking the plant, according to a literature review published in the Canadian Journal of Respiratory Therapy. Vaporization technology heats cannabis to a point where cannabinoid vapors form, but below the point of combustion.
"The vaporizer raises cannabinoid levels in humans but does not raise exhaled CO (carbon monoxide) levels," researchers concluded. "The majority of studies suggest that vaporizers adequately reduce risk of pulmonary symptoms."
Previous clinical trials of cannabis vaporization have concluded the method to be a safe and efficient vehicle for rapid cannabinoid administration.
