Travel sick - banning smoking in cars

Queuing in traffic around the north circular on the way to relatives was a feature of my childhood. As was my mother's stress at the combination of the length of the journey and my father's nose to tail break hard driving. Her need for a cigarette was pretty overpowering. I remember my brothers and I pleading with both our (health professional) parents not to smoke in the car - something they heeded as best as nicotine addicts can. We had to have the windows wound up to shut out the smell of traffic fumes only to be locked in the car with cigarette fumes. It was only the very real threat of me throwing up due to aforesaid breaking that stopped my mother lighting up.

This experience was probably pretty common in the 1970s and increasingly less common in the decades since - although Labour and co-operative MP Luciana Berger claims here that one in five children may still be exposed to smoke in cars. Whether it is out of ignorance of the harm they do or denial in the face of addiction, only legislation will force parents to confront what they are risking.

It's hard to know why banning smoking in cars is such a contentious issue. Yet it's a real fight - one that may well go down to the wire - just like banning smoking in public places - but we got there in the end with that. We have to hope that this government doesn't once again run scared of legislation to protect the public's health just as it did with plain packaging of cigarettes and minimum unit pricing of alcohol - although it may be tiptoeing back to reconsider the latter.

The House of Lords has backed Labour's proposal to ban smoking in cars carrying children. Ministers are now looking at how to implement such a ban. Disappointingly, however, deputy prime minister Nick Clegg said on his weekly LBC phone in that he was opposed to legislation that would allow the government to ban smoking in cars with children - calling it 'sub contracting parenthood'. But then I hadn't realised that Clegg was a smoker. Does he think car seats for babies is 'sub contracting parenthood' or is it just the smoking thing? Read the story here

There is widespread evidence here and here that second hand smoke harms those who breathe it in. That this is so was a strong feature of the argument for banning smoking in public places - those employed in pubs and clubs were forced to breathe in the cigarette smoke of punters hour after hour. Five years after the public smoking ban, there were reports of improved health amongst barworkers and it has been almost universally welcomed by them and by their customers. Although there are still hardy knots of people gathered outside pubs and clubs sharing nicotine and camaradrie with other smokers.

It was thought that the ban on smoking in public places would drive smokers back into the home to light up. But it seems this didn't happen. Many smokers took the opportunity to give up whilst many more at least took their smoking outside just as they had to when in a public place.

Of course, public health education must continue to be a big part of changing smokers' habits, together with support to help people give up. But we know from experience that public health campaigns are most effective in changing behaviour when they are backed by legislation. That was the lesson from introducing the law on wearing seatbelts, and the drink driving and smoking bans.

Children, of course, have no say in any of this but if they had, I don't believe one would say 'I wish Mum or Dad would smoke in the car.'

Going up in smoke

At last! Smoking -or rather not smoking - is beginning to show health benefits in the here and now that are more tangible to your average smoker than scary warnings about cancer and heart disease in the distant future.

Two recent studies have reported on the benefits that not smoking is having on young people. One in Pediatrics reported a sharp fall in the number of children admitted to hospital with severe asthma, linking it to the smoke free legislation introduced in England. Whilst another study in the US published in the American Journal of Public Health reported on the effectiveness of smoke free air laws and state tobacco control programmes on preventing youth smoking in the US. 

Earlier studies reported on the benefits to bar staff that the smoking ban has brought - for example, reductions in respiratory illnesses whilst other studies have reported on the reduction of admission to hospital for acute coronary syndrome.

The asthma study found that in the first three years after the ban on smoking in public places, introduced in England 2007, the number of admissions to hospital for childhood asthma was down by 6,802. Before the implementation of the legislation, the admission rates for childhood asthma were going up by 2.2%. The results were the same for boys and girls regardless of whether they lived in towns or rural areas, whether they were poor or wealthy. A similar fall in Scotland, where the public ban was enforced a year earlier was reported in a previous study.

The study allays early fears that there would be an increase in smoking at home if people were not allowed to smoke in public places. In fact, the researchers from Imperial College in London said that it appeared  that more people are moving towards having smoke free homes instead.

Capitalising on these benefits is key if public health is to maintain some sort of momentum to reduce smoking and ideally prevent children taking up smoking in the first place.  In recent years it seems the twin challenges of obesity and alcohol have come to the front whilst anti –smoking has been pedalling furiously behind. 

But the recent scary TV advertising showing a tumour growing out of a cigarette and the launch of the Department of Health’s recent Quick Kit Campaign http://campaigns.dh.gov.uk/2012/11/09/quit-kit-campaign-2013/ should see the stop smoking agenda back on track. And not before time, as another study published in the New England Journal of Medicine into women and smoking reported a steep increase in the risk of women smokers dying from lung cancer – attributable to more women smoking and also a decrease in mortality amongst women who were non-smokers. 

As my grandfather (the first in four generations of doctors/nurses/midwives) might have said: the three greatest causes of death are: smoking, smoking and smoking.
