Taking up vaping increases the likelihood that young people will end up smoking traditional cigarettes daily by three fold, a study has warned. US researchers studied data on the evolving tobacco product use more than 49,000 young people aged between 12–24 over four years. The team found that — among those who experimented with tobacco usage — the number of daily users increased with age through to 28 years old. In fact, the percentage of daily cigarette smokers nearly doubled between 18–21 year olds (at 12 per cent) and 25–28 year olds (at 21 per cent.) Experimenting with tobacco at a younger age and trying out multiple products — cigarettes, cigars, pipes, etc. — increases the risk of addition, the researchers said.
