In the past several years, the sale of recreational marijuana products, including cannabis vaping pens, has been permitted in 18 states. while medical use of cannabis has been legalized in 36 states. Cannabis vape pens are very popular cannabis products, and they widely vary in styles (from high-powered to portable) and heating mechanisms.  However, the chemical composition and toxicity of cannabis vapors are largely unknown. Due to the rapid increase in popularity of cannabis vape devices and the current lack of regulation and information regarding their chemical characteristics, there is an urgent need for evaluation and standardization of sampling and chemical analysis of cannabis vaping devices and their emissions. The specific aims of this collaboration are: (1) to perform detailed analysis of cannabis vaping emissions under different conditions and for various vaping devices, (2) to evaluate the performance of automated “vaping” machines in order to develop an adequate protocol for testing cannabis vaping products, (3) to evaluate the ideal conditions (temperature, concentration of terpenes and other organic compounds in vape liquid, type of device, etc.) for minimal toxicity of cannabis emissions, and (4) to summarize the results in a well-established protocol, which can be further proposed as a standard (reference) assessment method for the evaluation of cannabis vaping products.
