"We've found that the conversion rate from "first time smoker" to "daily smoker" is surprisingly high, which helps confirm the importance of preventing cigarette experimentation in the first place", Hajek added.
Research gathered from 215,000 survey participants in the U.S., U.K, Australia and New Zealand showed 60.3 percent of people had tried smoking cigarettes, and of those who tried it, an estimated 68.9 percent picked up a daily habit.
It shows around 50 to 82 percent people had gone for smoke on a daily basis or temporarily after trying a cigarette a day and when they combined the data, the percentage increased to 68.9%. The studies include three studies from the United Kingdom, three from the US, one from Australia and one from New Zealand.
The Delhi Police are fining people found smoking in public places, during its four-day trial against smoking in public places, under the Cigarettes and Other Tobacco Products Act (COTPA). In the United Kingdom, only 19 percent of 11 to 15 years olds reported having tried a cigarette, according to 2016 National Health Service, and in the USA, only eight percent of high school students reported having smoked in the past 30 days.
The smoking habits of more than 215,000 people were analysed by teams at Queen Mary, University of London, using global databases, including in the UK.
"The majority of people who try a cigarette go on to become regular smokers for at least some period of time, according to new research".
Because the surveys used different methodologies and thus yielded different results, researchers explained the estimated 68.9% "conversion rate" from experimentation to daily smoking has a margin of error, between 60.9% and 76.9%. "The presence of nicotine is clearly not the whole story", Hajek said.
"Concerns were expressed that e-cigarettes could be as addictive as conventional cigarettes, but this has not been the case". But they point out that the different surveys produced a range of results, so that figure is only an estimate.
