It follows research revealing that four out of five people believe there should be smoke-free areas in public places to protect non-smokers from tobacco smoke.
Lady Denton said: 'There is no doubt that many people do not want to be troubled by tobacco smoke when they go out for a meal or a drink. They quite rightly expect to be able to breathe air unpolluted by tobacco smoke which at best is unpleasant and at worst damaging to health. 'If they are to make informed choices about the places where they socialise they must have good information. I hope everyone who produces food and drink guides will consider including information that will help people to find a restaurant, pub or hotel that suits them.'
Lady Denton added that a letter urging consideration of a smoking policy in public areas is being sent to 24,000 restaurants, 7,000 cafes more than 500 breweries and 2,000 bus and coach operators in the United Kingdom.
