ACS on Vaping and Cancer: Still Encourages Smokers to Switch

Research team at New York University School of Medicine10 monthsA report published on the 7th in the Proceedings of the National Academy of Sciences said that they exposed 40 experimental mice to nicotine-containing electronic cigarette smoke (ECS) for 54 consecutive weeks, and 9 mice (22.5%) developed lung cancer. In addition, 23 animals (57.5%) developed bladder hyperplasia, increasing the risk of cancer.

Although the research team made it clear in the report that traditional cigarettes are still the biggest health killer, the experiment has not yet determined whether e-cigarette smoke will pose harm to the human body. E-cigarette smoke may or may not be harmful to the human body. The public should not use e-cigarette smoke The risk of cigarette smoke is equivalent to that of traditional cigarette smoke (TS) risks. However, whether e-cigarettes cause cancer still attract widespread attention among smokers.
 

In response to public concerns about whether e-cigarettes can cause cancer, the American Cancer Society (ACS) also expressed a clear attitude on its official website: Scientists are still studying the possible health hazards caused by long-term use of e-cigarettes. What is important is that the content of carcinogenic chemicals contained in e-cigarette smoke is much lower than that in cigarette smoke. content.

“Studies have found that the use of e-cigarettes is significantly less harmful to adults than ordinary cigarettes. Cigarette burning produces more than 7000 chemicals, at least 70 of which are clear carcinogens, while e-cigarettes do not have this problem. rdquo; The American Cancer Society further pointed out in its response that we encourage people to switch from traditional cigarettes to e-cigarettes. rdquo;
 

David, a professor of public health also from New York University·David Abrams, director of the research group, views e-cigarettes as the greatest opportunity in 120 years to improve public health if all American smokers switch to e-cigarettes. Will save at least 7 million lives.& rdquo; David Abram pointed out in an interview with Colombia.

During the interview, David·Abram has repeatedly said that there is sufficient and strong scientific evidence to prove that nicotine is an addictive substance, but it does not cause cancer, and the harmful components in e-cigarettes are at least 95% less harmful than traditional cigarettes.

 The above-mentioned carcinogenic experiment on e-cigarette smoke by the New York University School of Medicine research team has also caused controversy in China. An expert engaged in e-cigarette safety research who declined to be named said that the paper clearly pointed out that the direct carcinogenic factor is nitrosamines, not Nicotine itself. Some leading e-cigarette companies have very strict limits on nitrosamines in smoke fumes.

“Any discussion of toxicity apart from the dose is imprecise.& rdquo; The expert said.

According to the Yangtze Evening News, the Jiangsu Province Center for Disease Control and PreventionDuring a Smoke-Free Day event in 2016, the harm of traditional cigarette smoke to mice was demonstrated. The experimenters extracted the poison produced by a cigarette, dissolved it in distilled water in a test tube, and injected the solution into the mice. In less than 3 minutes, the white mouse fell to the ground feebly, shaking non-stop, and its limbs twitched and died.

A foreign researcher once did a study on smoking cigarettes“Animal test on second-hand smoke: Three lively white mice were placed in a relatively sealed box of about 0.17 cubic meters, and the smoke from three lit cigarettes was poured into the box. Within 10 minutes, all the white mice died.

In an experiment by the New York University School of Medicine research team, experimental miceThe amount of smoke exposed within 54 weeks is equivalent to the amount of smoke that adults smoke e-cigarettes regularly for 3 to 6 years. Based on this, it was concluded that e-cigarette smoke would cause bladder hyperplasia in experimental rats and increase the risk of cancer.

In reality, it is impossible for such a high smoke concentration to occur, and no one will be in the smoke for so long. In fact, the research team also emphasized at the end of the paper that the data derived from the experimental model only showed that the issue deserved further study.
