A new study published by King's College London emphasizes that daily use of e-cigarettes has a "significant effect" in helping to quit smoking, and the study compares other methods of quitting smoking, including nicotine replacement therapy or drug therapy, to support the effectiveness of e-cigarettes in helping to quit smoking.
Although the number of smokers in the UK has continued to decline in recent years, smoking remains the main cause of premature death and disease - nearly 75000 people died in the UK in 2019.
In a study funded by Cancer Research UK, researchers at King's College London analyzed online survey data from more than 1155 people, including smokers, former smokers who quit less than a year before completing the survey, and e-cigarette users.
Five waves of data were collected from 2012 to 2017. The researchers analyzed smokers who smoked for at least one month during the follow-up period, and smokers who quit smoking for at least one month between the first survey and the follow-up survey, to explore the effectiveness of e-cigarettes in helping to quit smoking.
The study, published in the journal Addiction, found that smokers who use e-cigarettes every day are more than five times more likely to quit than those who do not use smoking aids at all
