This Saturday, for the first time since 1965, an advert by a cigarette brand will be broadcast on British television.
The advert has been put together to promote the E-Lites electronic cigarette which does not contain tar or tobacco, but does deliver nicotine to the smoker.
The campaign has been criticised by some health campaigners, who say that e-cigarettes can normalise the smoking habit.
Scotland Tonight discussed the issue with ASH Scotland's Chief Executive Sheila Duffy, and Michael Ryan, the co-director of E-Lites.
