Ban on cigarette display

In the news this morning - cigarette displays in supermarkets and big shops to be put behind shutters.
There seem to be doubts as to what this will effect.

I just want to make a point that I haven't heard - that I have commented in the shop on the 'wall-to-wall' advertising of the display.....because I had stopped smoking and at the time it was bothering me seeing all these packets...
It could help people not to restart!
