Potential impacts of vaping without nicotine
In the world of vaping, the perception that it is a safer alternative to traditional smoking is common. However, recent research suggests that vaping without nicotine is not entirely risk-free, with potential long-term health effects that should be carefully considered.
Manufacturers often add flavorings or additives to the e-liquid mixture to create a particular flavor. While these ingredients may be food-grade, their effects on the body can change drastically when heated and vaporized. For instance, diacetyl, a flavoring linked to serious lung conditions, has been implicated in several lung diseases, including asthma and chronic obstructive pulmonary disease (COPD)[2][3].
Beyond lung health issues, vaping without nicotine can also pose cardiovascular risks. Substances in vape products may reduce venous oxygen saturation and affect vascular function[4]. General toxicity is another concern, as vaping can expose users to a variety of other chemicals, including volatile organic compounds and heavy metals[3][4].
Regulatory challenges also arise, as some nicotine-free vapes have been found to contain nicotine despite being labeled otherwise, introducing additional health risks[4].
It's important to note that the base liquid of e-liquids is a blend of water, vegetable glycerine, and propylene glycol. This liquid, also known as e-juice or vape juice, is vaporized by vape devices or electronic cigarettes.
While a 2019 study suggests that vaping can be a more effective method to stop smoking compared with other nicotine replacement methods, early research shows that vaping, even without nicotine, is not a completely safe alternative to cigarette smoking[1]. In fact, a 2020 laboratory study found that e-liquids had cytotoxic effects and induced DNA damage and chromosome breakage[1].
Moreover, chronic inflammation of lung tissue can lead to irreversible lung scarring, and heating and vaporizing e-liquid chemicals makes them especially toxic to lung cells[1]. Toxic chemicals such as acrylonitrile, acrolein, propylene oxide, acrylamide, and crotonaldehyde have been found in vape users' urine[1].
A 2018 study showed that adolescents who vape had significantly higher quantities of these toxic chemicals in their urine compared with those who had never used e-cigarettes[1]. The researchers caution against the widely held opinion that e-cigarettes are safe[1].
Inhaling propylene glycol and glycerol, common ingredients in e-liquids, can irritate the airways and increase the risk of lung infections[1]. Furthermore, a 2018 study found several common e-liquid flavoring ingredients caused a damaging inflammatory response in lung cell samples, without containing nicotine[1].
In conclusion, while vaping without nicotine eliminates the risk of nicotine addiction, it does not eliminate all health risks. Users are still exposed to potential lung and cardiovascular issues due to other chemicals present in vape products. Therefore, it is crucial to be aware of the ingredients and ensure that the products are free from harmful additives.
Research into the safety of vaping is still in its early stages, and large-scale studies are necessary to establish the long-term risks. Until then, it's essential to approach vaping with caution and make informed decisions about one's health.
