Terpenes, Dabbing And Carcinogens

Potentially bad news for those stoners that like to dab. According to new research, when the concentrated terpenes in wax are heated at high temperatures, they break down into a number of different chemicals, including the carcinogen benzene. Despite the significantly more powerful high one gets from dabbing, the potential health effects may turn off some users. Do you believe that dabbing is unhealthy? Would you stop dabbing based on this new information? Let us know in the comments below.

The terpenes that give marijuana its pungent odor play an intricate part in the molecular makeup of cannabis. Terpenes interact with cannabinoids creating what has become referred to as the entourage effect, which means that whatever combination of cannabis molecules a person ingests, and the ratio of specific molecules, affects the individually differently. People have manipulated marijuana to create extracts and will use a method called dabbing that involves extreme heat to create an intense immediate high.The intense heat along with the concentrate ends up making dabbing dangerous and unhealthy according to some recent research. Terpenes heated at high temperatures break down into a number of different chemicals including a carcinogen called benzene.

New research suggests that an increasingly popular method of cannabis consumption may pose more health risks than other methods on a chemical level.

A study published this month in the American Chemical Society’s ACS Omega found that a method of using cannabis known as dabbing may expose users to elevated toxin levels as compared to other methods. In a study of how the chemicals in concentrated cannabis break down under heat, Portland State University researchers Jiries Meehan-Atrash, Wentai Luo, and Robert M. Strongin discovered that concentrates exposed to the high heat common to dab setups produced elevated levels of carcinogenic and toxic compounds.

Dabbing, a process in which is heat is applied to certain cannabis concentrates to create an inhale-able vapor, has ballooned in popularity over the past several years, in large part because of its capacity to produce an extra-powerful high.

As the study noted, the principal product used in dabbing is butane hash oil (BHO), which is extracted from cannabis by adding and removing butane, and can resultingly have an active THC content of up to 90%–easily several times the amount you might find in regular dispensary-quality cannabis flower, a.k.a bud.

The team also explained, “Different nuances in its processing can lead to slightly different consistencies, which take on terms such as shatter, budder, crumble, pull-and-snap, wax, and so on.”

Users typically collect a globule or crumb of concentrate on a slim metal tool known as a ‘nail’ and use a water pipe or ‘dab rig’ to inhale the vapor produced. In order to release the vapor and active chemicals therein, users commonly use either a self-heating electronic nail or, in the case of simple metal nails, apply heat with a handheld blowtorch or similar tool.

According to the researchers, a key factor in which chemicals get released is the degree of heat used to activate products, which can themselves contain an array of materials and chemical proportions. In this case, as with previous research on e-cigarettes by the study’s senior author, Robert Strongin, Ph.D., it seems the higher the temperature that a substance’s flavoring terpenes are subjected to, the more carcinogens, toxins, and potential irritants are produced–meaning the (literally) hot art of dabbing could put users at greater risk than other methods.

In the researchers’ simulations, concentrates that were subjected to higher heat seemed to create vapor containing higher levels of methacrolein (MC), a “noxious irritant” related to the powerful pulmonary irritant acrolein, and benzene, a known carcinogen that’s been studied for years. Though benzene is a “ubiquitous pollutant,” unlike MC, the authors wrote, “the concentrations of benzene found in the dabbing terpenes at the highest [temperature range] are far greater than those found in ambient air.”
