I know this sounds like none of our business but. I listened to a phone in on Radio 5 Live this morning on the subject and expected vaping to get mentioned. It did no. The a guy phoned in and said " I am a smoker but I am cutting downs using...." it was edited out but I am sure it would have been e cigs. Censorship is not allowed on the BBC it has to be impartial. When it comes to vaping there is a whole new set of rules.
