This week featured No Smoking Day in the UK. It is difficult to judge if the effort put in to raising awareness about the dangers of smoking has had a significant impact. There’s no sign of the tobacco companies filing for bankruptcy, and smoking now kills more women than breast cancer. True there is a decline in men smoking in Western Europe, and a consequent slight drop in lung cancer mortality. But is this due to No Smoking Day? Or has society changed its attitudes to the habit, and banished it from "civilised" behaviour patterns? One thing is for sure – that no impact whatsoever is detectable on those in society who are socially deprived. They still smoke the most cigarettes, have the worst diets (with cheap alcohol constituting the principle calory source), take the least exercise, get more cancers, and die more quickly from those cancers. Ideas for turning this on its head are not numerous. In fact there are next to none. £4 billion spent by the NHS in the UK to tackle social inequalities have been wasted according to a recent audit. So what is plan B? Answers in a blog please!
