Oxford, Harvard and other university research institutions have confirmed that e-cigarettes are better than nicotine replacement therapy for smoking cessation.

  * Smoking is harmful to health, minors are prohibited from using e-cigarettes, non-smokers are not recommended to use e-cigarettes*

Recently, Oxford, Queen Mary University of London, Auckland University, Massachusetts General Hospital, Harvard Medical School and Lanzhou University, Research institutions such as McMaster University in Canada released two papers, respectively, through experiments and data investigation, and concluded that e-cigarettes have a better smoking cessation effect, compared with cigarettes have less harm, and the smoking cessation effect is even better than nicotine replacement therapy.
Smoking is one of the greatest public health threats the world has ever faced, with an estimated 1.3 billion smokers worldwide, causing more than 8 million deaths each year. Nicotine replacement therapy is an internationally recognized way to quit smoking, the main way is to use nicotine containing patches, chewing gum, throat lozenges and other products to replace cigarettes, to guide smokers to achieve the purpose of quitting smoking.
Researchers from Lanzhou University and McMaster University in Canada published a paper on the famous literature website TID (Tobacco Induced Diseases), showing that e-cigarettes have a better withdrawal rate than nicotine replacement therapy. The study was based on an experiment involving 1748 participants, and the analysis concluded that e-cigarettes were superior to nicotine replacement therapy in both the continuous withdrawal rate of more than 6 months and the 7-day withdrawal rate.
So far, beyond e-cigarettes and nicotine replacement therapy, there is no more effective way to quit smoking that has been widely confirmed by scientists. Other than irritation to the throat, the adverse reactions of the two ways are not obvious.
In addition, researchers from Oxford University, Queen Mary University of London, University of Auckland, Massachusetts General Hospital and Harvard Medical School jointly published a study on the Wiley Online Library literature website, analyzing follow-up surveys on people who use e-cigarettes to quit smoking. The study proposed that the scientific community generally believes that the risk of e-cigarettes is much lower than that of combustible tobacco, and they hope that through comparative analysis of data, whether smoking cessation through e-cigarettes can reduce the harm to the human body. To do this, the researchers divided a sample of 1,299 participants in Greece, Italy, Poland, the United Kingdom and the United States into: people who used e-cigarettes only, people who smoked, and people who used a mix of e-cigarettes and cigarettes.
The test results showed that in the detection of 13 potential harm biomarkers, 12 indicators were lower in people who only used e-cigarettes compared to smokers; Of the 25 potential harm biomarkers tested, only the use of e-cigarettes compared to e-cigarettes and cigarette users, 5 were lower. The low index potential hazard biomarkers include 3-hydroxypropyl mercapto acid, 2-cyanoethyl mercapto acid and o-toluidine.
The conclusion of the study shows that the use of electronic cigarettes instead of cigarettes, or the dual use of electronic cigarettes and cigarettes, can effectively reduce the harm to the human body.
