Smoking in private cars should be banned to protect children and the elderly, the British Medical Association has said.
There is now strong evidence that smoking in vehicles exposes non-smokers to high levels of second hand smoke which is known to be damaging to heath, the BMA said.
Because of the small enclosed space inside a car, smoking creates 23 times more toxins than found in a smoky bar, it was claimed.
Children absorb more of these pollutants than adults because their immune systems are not as developed and cannot fend off the harmful effects as easily, the BMA warned.
The elderly are also at greater risk because they are prone to respiratory problems that are worsened by breathing second-hand smoke.
