MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The need for this study stems from the rising popularity of cannabis, and specifically the fact that many consumers are under the belief that vaporizing extracts thereof is safer than smoking. While this may in fact have some truth to it, it is clear that we must assess the safety of vaporization a route of administration.

The main findings are that vaporizing terpenes under dabbing conditions generates some levels of methacrolein (a noxious irritant) at all temperatures that are hot enough to vaporize cannabinoids, but significant levels arise at higher temperatures that are more commonly used. To do this, you’ll need to make sure your dab rig is in excellent condition.

At the highest temperature used by consumers, significant levels of benzene arise, a compound that is a potent carcinogen and should be avoided at all costs.

MedicalResearch.com: What should clinicians and patients take away from your report?

Response: Readers should be left with the fact that vaporizing cannabis is not as safe as people have been lead to believe, and the practice should be completely avoided by youth and those with compromised immune systems.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: Our future direction in this research, which we have already begun, is to study the breakdown of cannabis extracts and cannabinoids in other forms of vaporization.
