Proportion of those in Great Britain who have never smoked before using e-cigarettes is negligible, according to ONS
A recent Columbia University study said it was a possibility e-cigarettes could act as a gateway to the non-electronic version and even to drugs such as cocaine. Action on Smoking and Health (ASH) estimate that there are 2.1m people in Great Britain currently using e-cigarettes.
The report states that the long-term health effects have not yet been established but doctors have said switching from tobacco to e-cigarettes could save 50,000 lives.
