Doctors have called for aban on smoking in all vehicles after a report into the effects of passive smoking on children.
A study by the Royal College of Physicians (RCP) found more than 20,000 chest infections, 120,000 bouts of middle ear disease and 200 cases of meningitis in youngsters are also thought to be linked to the effects of second-hand smoke.
The RCP is also calling for increases in the real price of tobacco, measures to tackle tobacco smuggling and illegal trading, and investment in media campaigns targeted at young people. Cigarettes should also be taken off display in shops and packaging should be made generic and standardised, doctors said.
Other measures include cutting down exposure to images of people smoking in the media - with films and television programmes which show gratuitous smoking classified as adult viewing - and stiff penalties for those who sell cigarettes to underage youngsters.
