The researchers calculated that 60.3% of people across the surveys had tried smoking a cigarette at least once.
The conversion rates (from one cigarette to daily smoking habit) varied quite substantially depending on the survey, the lowest being 50 percent (a USA survey) and the highest being 82 percent (a United Kingdom survey).
They looked at eight surveys conducted after 2000, with questions regarding trying a cigarette and smoking daily.
The authors conclude: "The transition from trying the first cigarette through occasional to daily smoking usually implies that a recreational activity is turning into a compulsive need that has to be satisfied virtually continuously".
They say that as the surveys used different methods, there was quite a wide margin of error and the "conversion" rate could be anywhere between 60.9% and 76.9%.
TWO in three kids get hooked on smoking from their first cigarette, a shocking study reveals.
"Alcohol can only be sold by licensed shops, while anyone can sell cigarettes, which are far more addictive and lethal".
"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", he said.
For example, among the eight surveys, each revealed different percentages for those who became daily smokers, ranging from 52 percent in the U.S.to 82 percent in the United Kingdom, meaning the two-thirds estimate was a weighted average, not a standard proportion. "The presence of nicotine is clearly not the whole story", Hajek said.
Meanwhile around 2.9 million people in the United Kingdom were e-cigarette users in 2016, it said.
