Mr. Paul Gordon:

We do not have a figure for use on a daily basis but overall for the general population it would be 5%. That includes daily users of e-cigarettes and occasional users. Again, more generally, we see a higher preponderance of it in younger people. It was mentioned that four in ten 15 to 16 year olds have used e-cigarettes. Some 16% of that group used an e-cigarette in the past 30 days, which is really worrying, particularly when taken in tandem with a rise in smoking rates among that group in the past few years, as pointed out earlier by Mr. Macey.
