Read the passage carefully.

 At home, I used to suffer enough with my husband who is a heavy smoker. Now, I am delighted that smoking is going to be banned in the majority of enclosed public spaces in Britain from July this year. In fact, I cannot wait for the ban to arrive. When hanging out, I am fed up with sitting in pubs with my eyes and throat hurting because of all the tobacco smoke in the air. As soon as I leave the pub I always find that my clothes and hair stink of cigarettes, so the first thing I do when I get home is to have a shower.

 It is not my problem if smokers want to destroy their own health, but I hate it when they start polluting my lungs as well. Passive smoking is a real problem, as a lot of medical studies have shown that non-smokers who spend a long time in smoky environments have an increased risk of heart disease and lung cancer.

 It is ridiculous when you hear smokers talking about the ban taking away their ‘rights’. If they are in a pub and they feel the need for a cigarette, obviously they will still be able to go outside in the street and have one. What is wrong with that? It will certainly be a bit inconvenient for them, but maybe that will help them to quit.
