7. "This ban will lead to bans in all cars, in people's homes and then everywhere"
Smoking in cars results in concentrations of toxins much higher than are normally found elsewhere - for instance, up to 11 times higher than you used to find in the average smoky pub. Children are much more vulnerable to these toxins than adults, and are also less able to choose alternative modes of travel or speak up if they don't like someone smoking. That's why parliament is only considering a ban on smoking in cars carrying children. Suggesting that other bans will inevitably follow insults the intelligence of the public to make up their minds on each law on a case-by-case basis.
17 December 2014: The government announces that smoking in cars that carry children will be a criminal offence. Action on Smoking and Health respond by saying:
"We are delighted that the Government is to press ahead with regulations to prohibit smoking in cars containing children. As with the smoke-free public places law, this is a popular measure that will largely be self-enforcing. However, secondhand smoke is just as harmful to adults as children and it makes it more difficult to enforce if it only applies to some cars, not all. Seatbelt laws don't just apply to children, why should smoke-free car laws?"
See how it works yet?
