But it does seem a 'big ask'.
For objections to this illiberal proposal, the first has to be the good word of the BMA itself, which campaigned heavily before the 2007 ban. It's representatives sent out to TV and radio stations laughed pompously at the objectors warnings of the slippery slope such a ban would put the UK on: it was only to protect innocent pub-goers, they said, who had no choice in what they breathed in when exerxising their alcohol imbibing rights. Don't they deserve to be protected?
That alcohol was by far the most hazardous part of a Friday night seemed to have been considered unimportant when smoking was coming to be seen as antisocial and presented an easy target of opportunity.
The law banning smoking in public places also overlooked that most of the affected locations were, in fact, privately owned, and no person was obliged to visit a smoking pub or restaurant.
For the ChildrenIt turns out that the ridiculed 'slippery slope' argiment was spot on, and campaigners are now openly pushing towards an outdoor ban and wispering about the move into homes. Of course, it will be phrased as if a ban was 'for the children', but you can be sure it will be a blanket ban that is demanded, as is the case for the current BMA proposal, for ease of enforcement.
Or just because smoker-persocutors are the new witch-finders and are bolstered by the political momentum to go for the criminalisation of tobacco, openly and without embarrassment.
Although I am, a lifelong non-smoker who has benefitted from smoke-free pubs and offices, I have fundamental objections to the BMA's demand:
First is the liberty one. It is no business of doctors, in my mind, to stop me doing risky things if the risk to others is small. I am not prevented from climbing mountains, paragliding, skating on icy lakes, driving a car at high speeds (with passengers), and drinking alcohol. The BMA has not yet suggested banning these activities, but since they have a habit of sliding down the slippery slope, I am willing to draw the line at banning smoking.
Fake FiguresThe second objection is the '23 times more toxic than the smoky pub' figure that is being quoted withoud attribution. The Today program speaker explained that this was the case even when no smoking was actually happening since the 'toxins' soaked the inside of the car. Is this serious? Just what was measured? And did it really equate to 23 times more hazardous than a pub atmosphere? It seems remarkably suspicious, and the BMA today withdrew its claim (See the Factcheck site for a debunking of this media myth, with sources.)
The argument for a wholesale ban on in-car smoking is a practical one: that it will be easier to enforce 'for the children' if everyone was banned. This will include people without children, and people who will never carry children in their cars. In a spirit of tolerance, only dangerous activities should be prohibited - anything else is just illiberal. Why ban people from smoking in their own car just to make enforcement easier? (Foreign laws against smoking in cars only forbid smoking with a child in the car.) It will clearly result in the bulk of prosecutions being of drivers of cars with no children, since they are the ones who will most disagree with such a law.
Slippery SlopeThe final criticism is made with the slippery-slope argument. Usually a poor excuse for logic, the current debate has used the existing ban on smoking in work vehicles and public spaces as justification. One can easily imagine a future when the argument move on to be that the only place a child can breathe smoke is in the home, so that it is a dangerous loophole that should be closed.
Intolerance breeds intolerance by emboldening the nannys that build on victory after victory, incrementally moving us from the traditional character of the country, where a free person can partake of anything not specifically banned, to the continental tradition where you can only do what is specifically prescribed, with everything else forbidden.
The BMA took a fake fact about smoking with children in the car and made it into an attack on all smokers. Anyone who values the freedom to choose what risks to take for themselves will be wise to protest this move - if this moves onto the statute book, the nanny campaigners will not stop there in their programme to save us from ourselves.
