Thank you.
It's not my rolling survey. It's carried out by Professor Robert West at the University College London. It's available online if you search under Smoking in England and the latest electronic cigarettes statistics. What he shows is that over the last two or three years there has been a progressive increase in use by smokers, both occasional and regular use. Largely, the use of electronic cigarettes has been cannibalizing the market in over-the-counter nicotine replacement therapy products.
What we see is a great deal more smokers using a nicotine product, if you lump NRT and electronic cigarettes together, and as a consequence, increased quit rates and increased numbers of smokers trying to quit.
Does that answer your question?
