Living in Scotland, which has an astronomical tally of smoking-related diseases, many of us are counting the days until 26th March. In the meantime. as others have said above, more and more folk clubs are going smokeless, but you still have to hold your breath as you go in the door, or even to our local hospitals, to get past the ostracised smokers puffing away right outside said buildings.
On the positive side, several smokers I have met in my professional capacity say that the ban will in fact make it easier for them to give up.
My husband's college provided a smoking room for the smokers when the rest of the college went smokeless, but even the smokers found it "too smoky"!
