While concentrates, vapor pens, and e-liquids may be labeled under the same strain names, the extraction process eliminates and alters many of the terpene aroma molecules found inside whole cannabis flower. Concentrates contain very different terpenes than dried flowerĬoncentrates, e-liquids, and vapor cartridges are not exactly the same as cannabis flower. Hoping to avoid pesticides in cannabis products? Opt for brands that third-party batch test their products and post the results online. In fact, a 2015 study published in the Journal of Toxicological Sciences found that up to 80 percent of over 57 samples of California cannabis concentrates contained unsafe levels of residual pesticide. Therefore, a vapor cartridge or BHO extraction is more likely to contain more concentrated quantities of contaminants. While one of those flowers individually may not contain unsafe levels of pesticide, a highly concentrated oil made after extracting resin from a great many plants may be more problematic.Ĭannabis extractions concentrate resin, including pesticides that may be attached to that resin. Why? A batch of cannabis concentrate may be equivalent to several pounds of cannabis flowers.
Vapor cartridges, e-juices, and other types of cannabis concentrates are more likely to contain residual pesticide contaminants than flower. Concentrates may contain higher levels of pesticide contaminants Hoping to play it safe with vapor pens? Opt for products that list their ingredients and do not contain PG or PEG. The study found that MCT oils can break down into a carcinogen known as acetaldehyde when exposed to high heats, but levels of acetaldehyde from MCT oils were still 33 times less than that found in PEG.

Specifically, PG and PEG are both converted to the known carcinogen formaldehyde with heat.įormaldehyde is also used to preserve cadavers for scientific experimentation and is a well-known lung and skin irritant.įortunately, the study found that other additives like vegetable glycerine did not pose a health risk. The point of combustion for cannabis products is 446F (230C). Food and Drug Administration (FDA) they can transform into more dangerous substances when heated to the point of combustion. Unfortunately, while these additives are generally recognized as safe by the U.S. The two additives in question? Propylene glycol (PG) and polyethylene glycol (PEG).īoth substances are commonly added to e-juice and vapor cartridges to thin out an otherwise thick, honey-like material. In a 2017 report published in the Journal of Complementary and Alternative Medicineshowed that certain common additives to vapor pens may pose health risks. Some vape pens contain harmful additivesĪs it turns out, some vape pens may not be so safe. Here are five things to consider when looking for a safe vapor pen: 1. Not all vape pens carry the same safety risks. Why? The quality of vapor pens can range wildly depending on how a cannabis concentrate was processed and made.įortunately, there’s some good news. Yet, some experts are calling bluff on the idea that all cannabis vape pens are safe. In fact, the first long-term, peer-reviewed study on the subject was published in early 2017 in the journal Annals of Internal Medicine.Īfter examining blood and urine samples from 181 participants, British researchers discovered that those who switched to vaporization and electronic cigarettes showed significantly lower levels of carcinogens and other toxic chemicals than consumers who smoked. In general, vaporization is considered a far safer alternative to cannabis smoking. Most often made using solvents to strip the herb’s essential oils from plant material, concentrates are most often used in vaporization or inhaled via special “rigs” used for instant vaporization of oils.
In fact, the market for concentrates and vapor pens has increased by 145.6 percent between 20 in Washington state alone. Concentrates and vapor pens are among some of the fastest growing markets in the cannabis industry.
