Although the letter in this article isn't highlighting e-cigs as such,I do feel it is worth adding comments as Dr Patrick Basham does mention harm reduction in his last paragraph :-
"There are still several million British adults who continue to smoke and its to this group that harm-reduction products should be directed. Such reduction is, therefore, a legitimate extension of earlier initiatives to reduce the health burden of smoking."
