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.
