The letter has a misleading title, it identifies no 'unsubstantiated claims'. It just says that some ex-smokers would quit anyway and that surveys have a margin of error. It raises no material issues that would suggest that the article's finding of a huge number of smokers who claim to have stopped smoking with the help of e-cigarettes is inaccurate.
