The number of smokers in Britain has more than halved over the last 40 years, a new survey has revealed.
According to the General Lifestyle Survey, 45% of people smoked in 1974, compared with just 20% in 2011.

“The UK is seeing a year on year increase in alcohol related deaths especially liver disease and what makes this worse is that average age of people dying from liver disease is decreasing,” said Andrew Langford, British Liver Trust chief executive.

In 1974 51% of men smoked cigarettes, compared with 41% of women. The newest figures show there is now only a 2% difference between male (21%) and female smokers (19%).
The report shows that married people are less likely to smoke than single people, and the unemployed are
