Portable electronic devices, known as “vape pens,” are popular among medical marijuana patients among others since they offer a convenient, discreet, and presumably benign way to administer cannabis. So how safe are vape pens and the liquid solutions inside the cartridges that affix to these units? That knows what’s actually being inhaled?
It’s generally assumed that vaping is actually a healthier means of administration than inhaling marijuana smoke, that contains noxious substances which could irritate the lungs. Since a vaporizer heats the cannabis flower or oil concentrate without burning it, the active ingredients are inhaled but no smoke is involved. A minimum of that’s how it’s designed to work.
But there might be a hidden disadvantage in vape pen battery, which can be manufactured (typically in China), marketed, and utilized without regulatory controls. Available online as well as in medical marijuana dispensaries, vape pens consist of a battery-operated heating mechanism, which at high temperatures can transform solvents, flavoring agents, and other vape oil additives into carcinogens as well as other dangerous toxins.
Of particular concern: Propylene glycol, a popular chemical which is blended with cannabis or hemp oil in numerous vape pen cartridges. A syrupy, thinning compound, propylene glycol can also be the main ingredient in most of nicotine-infused e-cigarette solutions. At high temperatures, propylene glycol converts into tiny polymers that will wreak havoc on lung tissue.
Scientists know a great deal about propylene glycol. It can be found in an array of common household items-cosmetics, baby wipes, pharmaceuticals, pet food, antifreeze, etc. The United states Food and Drug Administration and Health Canada have deemed propylene glycol safe for human ingestion and topical application. But exposure by inhalation is another matter. Many things are safe to consume but dangerous to breathe.
A 2010 study published from the International Journal of Environmental Research and Public Health determined that airborne propylene glycol circulating indoors can induce or exacerbate asthma, eczema, and several allergic symptoms. Children were reported to be particularly understanding of these airborne toxins. An earlier toxicology review warned that propylene glycol, ubiquitous in hairsprays, might be harmful because aerosol particles lodge deep in the lungs and so are not respirable.
When propylene glycol is heated by way of a red-hot metal coil, the potential harm from inhalation exposure increases. High voltage heat can transform propylene glycol and other vaping additives into carbonyls. Carbonyls are a team of cancer-causing chemicals that features formaldehyde, which was related to spontaneous abortions and low birth weight. A known thermal breakdown product of propylene glycol, formaldehyde is surely an International Agency for Research on Cancer group 1 carcinogen.
As a consequence of low oral toxicity, propylene glycol is classified from the FDA as “generally defined as safe” (GRAS) for usage like a food additive, but this assessment was based on toxicity studies that failed to involve heating and breathing propylene glycol.
Prevalent in nicotine e-cig products and offer in a few vape oil cartridges, FDA-approved flavoring agents pose additional risks when inhaled rather than eaten. The flavoring compounds smooth and creamy (diacetyl and acetyl propionyl) are related to respiratory illness when inhaled in tobacco electronic cigarette devices. Another hazardous-when-inhaled-but-safe-to-eat flavoring compound is cinnamon ceylon, which becomes cytotoxic when aerosolized.
Currently, there is absolutely no conclusive evidence that frequent users will experience cancer or some other illness once they inhale the contents of vape oil cartridges. That’s because little is actually known regarding the short or long-term health results of inhaling propylene glycol along with other ingredients that are present in flavored vape pen cartridges. Many of these prefilled cartridges are poorly labeled with little or no meaningful information about their contents.
The opportunity that vape starter kits might expose men and women to unknown side effects underscores the value of adequate safety testing for such products, which thus far continues to be lacking.
Scientists face several challenges because they try and gather relevant safety data. As yet, no person has determined how much e-cig vapor the typical user breathes in, so different studies assume different amounts of vapor as his or her standard, rendering it difficult to compare results. Tracing what occurs towards the vapor once it is actually inhaled is equally problematic.
The largest variable will be the device itself. The performance for each vape pen can differ greatly between different devices and sometimes there is considerable variance when you compare two devices of the same model.
Some vape pens require pressing a control button to charge the heating coil; others are buttonless and one activates the battery by just sucking about the pen. The outer lining part of the vape pen’s heating element along with its electrical resistance play a huge role in converting ingestible solvents into inhalable toxins.
Another confounding factor may be the scant information about when and exactly how long the consumer pushes the button or inhales normally, the length of time the coil gets hot, or the voltage used throughout the heating process. A five-volt setting yielded higher quantities of formaldehyde in the controlled propylene glycol study cited from the New England Journal of Medicine.
When it comes to vape pens, there’s a fantastic requirement for specific research about how people actually use these products in real life to be able to understand potential benefits or harms.
Such reports have been conducted making use of the Volcano vaporizer, the first generation vaping device that differs from a vape pen, an even more recent innovation, in many ways. Found in numerous studies like a medical delivery device, the Volcano will not be a portable contraption. The Volcano only heats raw cannabis flower, not oil extract solutions, and it also doesn’t combust the bud.
Vape pen manufacturers don’t want to admit it, however, when the heating element gets red hot in a vape pen, the perfect solution within the prefilled cartridges undergoes a process called “smoldering,” a technical term for which is tantamount to “burning.” While most of the vape oil liquid is vaporized and atomized, a part of the vape oil blend undergoes pyrolysis or combustion. In this sense, a lot of the vvape pen starter kit that have flooded the commercial market is probably not true vaporizers.
Unlike vape pen devices, the Volcano vaporizer has been tested for safety and pharmacokinetics (a measurement of what’s inside the blood and how long it stays there). Collectively, the data vapeopen that vaporizing whole plant cannabis exposes the user to decrease amounts of carcinogens in comparison with smoke and decreases negative effects (such as reactions on the harshness of smoke).
But nonportable vaporizers such as the Volcano may still pose health problems if the vaporized cannabis flower is below acceptable botanical safety standards. A recently available article inside the Journal of Analytical Methods notes that high quantities of ammonia are designed from vaporizing cannabis grown incorrectly, perhaps because of the deficiency of flushing during hydroponic cultivation. There’s a developing body of web data suggesting how the chemicals used to push the plant towards unnaturally high THC concentrations stay in the finished product.
