Harm Reduction and Alternative Delivery Methods for Cannabis Consumption

"The use of a vaporizing device may mitigate some of these symptoms. Cannabis vaporization is a technique aimed at suppressing the formation of irritating respiratory toxins by heating cannabis to a temperature where active cannabinoids are volatilized, but below the point of combustion where smoke and associated toxins form. The use of a vaporizer is associated with higher plasma THC concentrations than smoking marijuana cigarettes, little if any carbon monoxide production, and significantly fewer triggered respiratory symptoms."
