A recent study conducted in the USA, New Zealand, Australia and the United Kingdom shows that 68% of those who tried smoking, at one point, become daily smokers. It has been proven that the rate of becoming a smoker after experiencing smoking for the first time is higher than expected.
Prof Hajek said the data suggest the devices were not causing more people to take up tobacco.
It was shown that 60.3 percent of respondents had ever tried a cigarette, with an estimated 68.9 percent of these progressing to daily smoking.
Researchers from Queen Mary University, London, analyzed the results of eight surveys on smoking habits in English-speaking countries and found that a single cigarette is enough to spark a daily smoking habit - at least temporarily - in 69 percent of people. The studies include three studies from the United Kingdom, three from the U.S., one from Australia and one from New Zealand.
While it is natural to see some variation between surveys, it is interesting to note that United Kingdom respondents were consistently more likely to say they developed a habit compared to those from the other three countries.
The dramatic shift from one-time smoking to a daily habit added to the evidence of the dangers of cigarette addiction, and the researchers believe their information could help in creating guidelines to prevent teens from even trying out cigarettes for fun.
In 2016, 15.5% of adults from the United Kingdom smoked - about 7.6 million people - according to the Office for National Statistics, down from 19.9% in 2010.
In 2016, male smokers had an average of 12 cigarettes a day while women lit up 11 daily.
He added: 'It is striking that very few non-smokers who try e-cigarettes become daily vapers, while such a large proportion of non-smokers who try conventional cigarettes become daily smokers.
While, concerns were expressed that e-cigarettes could be as addictive as conventional cigarettes, but this has not been the case, the study stated.
"We want to celebrate the quit attempt itself because the evidence is clear, the more attempts you make to quit the more likely it is that you will succeed", says Zeller.
