Study: E-cigarette use rises rapidly over 2 years in Britain and France

The number of people in France and Britain who have tried an electronic or e-cigarette has risen sharply in just two years, according to a Europe-wide study published on Tuesday.

The research, led by scientists at Britain's Imperial College London, looked at attitudes to and use of e-cigarettes across Europe between 2012 and 2014.

It found that France had the highest use of e-cigarettes, with the proportion of those who had tried one nearly tripling to 21.3 percent from 7.3 percent.
