On September 14, 2021, Cochrane Collaboration, an internationally authoritative academic organization of evidence-based medicine, published their latest research on the effectiveness of e-cigarettes in quitting smoking.

Can e-cigarettes help people quit smoking? Will using electronic cigarettes to quit smoking produce adverse reactions?

This new study builds on the previous review and adds five new studies to the overall work. The purpose of this review is to examine the effectiveness, tolerance and safety of using electronic cigarette equipment to help smokers quit smoking for a long time.

Cochrane conducted 61 studies among 16759 smoking adults. Their research found that nicotine e-cigarettes can help people quit smoking for at least six months. They also found that e-cigarettes are more effective than nicotine replacement therapy and e-cigarettes without nicotine.

Among them, 2886 subjects used nicotine e-cigarettes, 1924 subjects used nicotine replacement therapy, and 1447 subjects used nicotine free e-cigarettes.

The study found that for every 100 people who use nicotine e-cigarettes to quit smoking, 9 to 14 people may successfully quit smoking; In contrast, only 6 out of 100 people successfully quit smoking using nicotine replacement therapy, and 7 out of 100 people successfully quit smoking using e-cigarettes without nicotine.

Cochrane research team said that we are not sure how much difference exists between the adverse effects of using nicotine e-cigarettes and nicotine replacement therapy. There is some evidence that non serious adverse effects are more common in the group receiving nicotine e-cigarettes than in the group without external support. Compared with non nicotine e-cigarettes, people using nicotine e-cigarettes may have no difference in non serious adverse effects.

The most frequently reported adverse reactions of nicotine e-cigarettes are throat or oral irritation, headache, cough and discomfort. As people continue to use nicotine e-cigarettes, these effects will decrease over time.

In short, the research review found that nicotine e-cigarettes can help people quit smoking for at least six months. It also found that they are more effective than nicotine replacement therapy and nicotine free e-cigarettes. The report goes further and determines that they may be better than no support or behavioral support alone, and that they may not have serious adverse effects.

John Dunne, director general of UK e-cigarette Association ukvia, agreed with the latest research of Cochrane team.

Dunn said the evidence was clear that e-cigarettes were less harmful and extremely effective in quitting smoking.
