Does vaping cause cancer?

Is vaping harmful to the body, can it cause cancer? In fact, people who have this question are mainly worried about the nicotine in the e-cigarette liquid. At present, online comments believe that nicotine can cause cancer, and e-cigarette e-liquid also contains nicotine, so smoking e-cigarettes will also cause cancer. But the fact that nicotine does not cause cancer and that nicotine itself is harmful may lead to public fear and avoidance of low-risk nicotine products like e-cigarettes. The following is an excerpt of Zhihu's best answer on whether nicotine can cause cancer.

Nicotine, nicotine, Nicotine and caffeine are an important alkaloid in the history of modern human civilization, one of the many highly toxic alkaloids from nightshade plants

It is not easy to say whether nicotine is the "most toxic" in cigarettes. In fact, carbon monoxide and tar were once considered to be the main culprits of the harm of cigarettes. However, there is no conclusive evidence that nicotine can cause cancer in vivo studies on the carcinogenicity of nicotine, but it can be confirmed that the source of cigarette addiction is nicotine.

Tar itself is also a major source of smoking harm. Although as mentioned above, the carcinogens in tar are trace amounts, but if you smoke for a long time, after the tar itself is inhaled into the respiratory system, it will adhere to the surface of the respiratory system and affect the respiratory function. This is also the reason why the trend of "reducing tar and harm reduction" in the global tobacco industry and national legislation prohibits the sale of cigarettes with a tar content of more than 11 mg per stick.

A new study provides startling evidence that Americans misunderstand the relative safety of nicotine. More than half of adults (52.9%) believe nicotine causes most cancers in smoking, and another 21.2% are not sure.

Almost as many smokers - 52.5% - think nicotine is a carcinogen. This means they may be less likely to use vaping products, or even nicotine replacement therapy products like gum and patches, because they may not think these products are any safer than smoking.

The study also reflects this concern. Among the smokers surveyed, only 31.6% believe that e-cigarettes are less harmful than smoking. 3.4% thought vapes were much less harmful. Even vapers are misguided, although they are less so than smokers and non-smokers. The study found that 14.6 percent believed nicotine caused cancer.

The research comes from Washington-based consulting firm Pinney Associates. The findings, presented last month at the Society for Research on Nicotine and Tobacco (SRNT) annual meeting in Baltimore, have not yet been made public. Pinney researchers analyzed data from the National Cancer Institute Health Information National Trends Survey to arrive at their conclusions.

"Despite longstanding FDA-approved over-the-counter nicotine replacement products, misconceptions about the health effects of nicotine in adults persist, which is disturbing and needs to be made clear to the public, especially smokers, that nicotine is not associated with smoking-related illnesses. ” said lead author Karen K. Gerlach, Ph.D., in a press release.

She added: "Public health experts are calling for credible authorities to clearly communicate nicotine messages to smokers, which should help them understand that there is a continuum of risks in products containing nicotine, and use that understanding to help them Reduce risks to health."

However, the real risks of using non-flammable nicotine products have not been published by trusted authorities. The possibility that nicotine affects adolescent brain development is based solely on rodent behavioral studies. Findings like these are often touted as a reason to rein in vaping products, even by doctors like FDA Commissioner Scott Gottlieb.
