Ok point taken, no worries
Generally, in my observation of this thread, I've noticed there is a lot of arguement, about whether or not there will be problems with 'Noise Levels' outside pubs, among other things, etc. and I can only say that there WILL be changes in people's social, drinking habits, as a result of the ban, that is inevitable.
You wont have to wait too long to see them either, 2 or 3 months at most.
If non smokers are under any illusion, that the whole place is suddenly going to turn into some kind of 'non smokers utopia', forget it, the ban will affect you in other ways. If bar owners have to build, and heat, smoking areas, they will start charging more for their beer, and that will cost you too, as well as the smokers.
I'll be bold enough to make a few other predictions.
IMO
The law will not see smokers quitting on mass, Smokers will, by and large, continue to smoke, they will just do it elsewhere, where they are allowed to.
Bouncers will have new problems seperating smokers standing outside, from random drunk people wanting to come in to a pub/club
Pubs without a smoking area, especially in rural areas will suffer, and some may close.
There will be an increase in private partys in peoples houses/apartments.
Off Licence sales will go up.
In some cases, peoples social groups will fragment, with smokers and non smokers drifting in their separate ways.
Pubs/Clubs in the city centre, with a good heated smoking area, will fare better than those that don't.
By Spring and Summer, you will find as many non smokers, as smokers, in the smoking area.
I could be proved wrong with 'some' or indeed 'all' of the above, but you will all know, by about March or April, however, the Winters are, by and large, the Acid Test.
