A nudge is a good as ...

The government's Nudge unit or, more properly, the Behavioural Insight Team (BIT) has suggested that smokers be encouraged to use smoke-free cigarettes, an idea that has not been met with universal approval. The suggestion, which has been pounced upon by the press, comes in the BIT's annual update. In the US, electronic cigarettes (e-cigs) are not approved as smoking cessation products and the Food and Drug Administration continues to have concerns about their manufacture and marketing. Thus, there was substantial press coverage of a study of e-cig users in the International Journal of Clinical Practice that sounded a slightly more positive note.
