Cancer-Causing Compounds Found in Cannabis Oil
As the legalization of marijuana continues to spread among various states within the U.S., researchers, and physicians are trying to fully grasp the potential health hazards of the recreational use of the drug. Since marijuana can be consumed through a variety of methods—e.g., eating, smoking, or vaporizing—it is important to understand if and how drug delivery methods affect users. With that in mind, a recent study from investigators at Portland State University found benzene and other potentially cancer-causing chemicals in the vapor produced by butane hash oil, a cannabis extract.
Findings from the new study—published recently in ACS Omega in an article entitled “Toxicant Formation in Dabbing: The Terpene Story”—raises health concerns about dabbing, or vaporizing hash oil—a practice that is growing in popularity, especially in states that have legalized medical or recreational marijuana. Dabbing is already controversial. The practice consists of placing a small amount of cannabis extract (a dab) on a heated surface and inhaling the resulting vapor.
