Should Smoking Be Banned in Private Cars?

[les_taxi]

The point of Keith's thread was whether there was research to show if there was a safety issue, resulting in careless or dangerous driving

Well the headline read Should Smoking Be Banned in Private Cars?
Then passive smoking was mentioned,then the safety issue,I don't smoke myself but have been in smokers cars and their driving was fine

Les, I trust you and when I'm next in Harrogate ( a more affluent town than Scarborough ) I will be happy to be driven in your smoke-free taxi (but with substantial discount as a forum member and retired doctor ).
I think we're all agreed the evidence is there that passive smoking is a health hazard. What really is more difficult to answer is whether there is also evidence for smoking as a safety issue while driving.
