Can vaping really help you quit smoking? Whether e-cigarettes belong to tobacco has been a contentious topic in China. Recently, e-cigarettes have once again come under public scrutiny. A video titled "E-cigarettes on Beijing Subway Line 10" went viral on Weibo, garnering 600,000 views in just one hour, sparked by a woman vaping on the subway.
Previously, there was an incident where a co-pilot vaping caused an emergency descent of a flight. Smoking and vaping differ by just two words, but what is the actual difference? The distinctions are significant; for example, e-cigarettes are not included in the "Regulations on Smoking Control in Public Places."
E-cigarettes are a non-combustible tobacco alternative. They use a battery to generate heat and provide a device for vaporizing nicotine, functioning through an internal nicotine delivery system, and can be filled with liquids containing varying concentrations of nicotine. In simple terms, an e-cigarette is a "liquid tobacco component" vaporizing device powered by a battery. E-cigarettes include disposable simulated e-cigarettes, cartridge-based e-cigarettes, pre-filled liquid e-cigarettes, and refillable liquid e-cigarettes.
E-cigarettes also produce secondhand vapor.
What is the difference between e-cigarettes and traditional cigarettes? Before answering this question, it's necessary to briefly look at the various components in e-cigarettes. The liquid tobacco components mainly consist of water, propylene glycol/glycerin, nicotine, and flavorings.
Contact with propylene glycol/glycerin—short-term inhalers may experience increased coughing, dry throat, chest discomfort, and increased phlegm, while long-term inhalers may suffer significant declines in lung function.
Contact with nicotine—short-term inhalers may experience increased neurotransmitter metabolism and release, leading to elevated heart rate, blood pressure, and blood sugar fluctuations. Symptoms may also include increased phlegm and thicker viscosity. Additionally, nicotine can reduce cell proliferation and inhibit apoptosis. In rat experiments, long-term exposure to nicotine can lead to epigenetic reprogramming and impaired lung development, resulting in intergenerational asthma.
Contact with flavorings—may induce asthma in individuals with allergic constitutions. For taste experience and satisfaction, most e-cigarettes sold on the market contain tobacco extracts or nicotine components. Furthermore, in basic research, researchers have detected the presence of toxic substances such as acetone, acrolein, butadiene, cyclohexane, ethylene glycol, ethanol, formaldehyde, tobacco alkaloids, nitrosamines, butanone, metals (cadmium, lead, nickel, copper), and toluene, in addition to the aforementioned substances.
There is also the notion of secondhand vapor from e-cigarettes. Although the levels of carcinogenic compounds and other toxic substances are 1-2 orders of magnitude lower than those produced by traditional tobacco combustion, some e-cigarette products still show significantly high levels of toxic substances. It is worth noting that since e-cigarettes have only recently entered the market, and diseases such as chronic obstructive pulmonary disease, coronary heart disease, and cancer take a long time to manifest, it will be difficult to obtain conclusive evidence regarding the association between e-cigarette use and related diseases in the coming years.
The efficacy of e-cigarettes as a substitute remains questionable.
Currently, the World Health Organization defines e-cigarettes as an unverified nicotine replacement therapy, lacking scientific evidence to prove the safety and effectiveness of these products. The following is data from a prospective study on e-cigarettes assisting smoking cessation among American adults: the proportion of those who successfully quit smoking without continuing to use e-cigarettes is 6.67%, while those who became dual users of cigarettes and e-cigarettes account for 53.47%, with the smoking cessation rate using e-cigarettes ranging from 5% to 40%.
As international tobacco giants venture into the e-cigarette industry, e-cigarettes will soon enter the artificial intelligence phase. Research is no longer limited to circuits and atomizers but has increasingly focused on the impact on human functions, addiction studies, and other foundational research related to product quality and safety. With this foundational data support, comprehensive system standards regarding e-cigarette materials, design, production, and equipment will emerge in the coming years. Meanwhile, we should note that e-cigarette companies are no longer satisfied with online sales. Physical chain stores and offline markets are gradually forming under the push of enterprises. Because of this, in the foreseeable future, China will face an increasing number of issues related to e-cigarette use, including a series of threats regarding safety and harm.
In my opinion, e-cigarettes should be included in the public smoking ban. For individuals with severe tobacco addiction, e-cigarettes may serve as a transitional tool in the quitting process, but that does not mean they can use e-cigarettes indoors in public places.
