Scientific evidence once again proves that electronic cigarettes can effectively help smokers quit smoking.

Recent research shows that electronic cigarettes can help more people quit smoking than nicotine replacement therapy (NRT). But for nicotine addictors, e-cigarettes have no magical effect on nicotine addiction. After the end of the one-year trial period, most smokers who have tried e-cigarettes will continue to smoke, while most e-cigarettes who have quit will continue to use e-cigarettes after one year.

A study published Wednesday in the New England Journal of Medicine found that 18% of smokers had successfully quit smoking after switching to electronic cigarettes for one year, 9.9% more than those who used traditional smoking cessation aids such as patches, gum, ingots or inhalers. The results show that e-cigarettes can indeed help people quit smoking, but the impact of long-term use of e-cigarettes on human health and how to make millions of adolescents do not use e-cigarettes are unclear.

Electronic cigarette companies often use their products as low-risk alternatives to quitting smoking, but the CDC says “traditional cigarettes are very dangerous and half of long-term smokers will die as a result.” Vox reports that there are few rigorous tests comparing e-cigarettes with other smoking cessation supplements, such as patches or chewing gum.

Although not involved in the study, Gideon St. Helen, a tobacco research expert from the University of California, San Francisco, said: “This kind of study is a systematic, rigorous and reasonable randomized controlled trial, which has been seriously lacking in the debate over the potential benefits and hazards of e-cigarettes over the past decade.”

A team led by Peter Hajek, Professor of Clinical Psychology, Wolfson Institute of Preventive Medicine, tracked 866 long-term smokers who wanted to quit smoking. In the first month, all quitters met with clinicians once a week. Half of the quitters used traditional nicotine replacement therapy based on communication, while the other half received an introductory kit for electronic cigarettes, including a bottle of Tobacco Royale’s cigarette oil. Participants can change electronic cigarette equipment or fume according to their needs.

Researchers regularly checked participants to assess their sleep status, whether they felt nausea, whether their throat or mouth was injured, and how much sputum they coughed. The most important thing is to check whether participants quit cigarettes within a year. The researchers examined participants’exhaled carbon monoxide – a sign of smoking. One year later, 18% of e-smokers quit smoking and 10% of nicotine replacement group quit smoking.
