Believe it or not, people actually like smoking and eating fatty food

Public information campaigns and nutritional labelling are good at informing people about what’s healthy and what isn’t, but don’t seem to have much impact on what they actually eat. That’s what a comprehensive review of 121 'healthy eating' policies found, and I think it should make us rethink more heavy-handed policies to do with unhealthy food, tobacco and alcohol. There are benefits as well as costs to every activity that public health groups want to discourage. We know there are benefits because people do them freely. But we know there are costs as well, like living a shorter and less healthy life.

The liberal view is that each person’s cost-benefit calculation is different, because they enjoy and dislike things differently. In this view there’s no case for stopping people from doing things unless they don’t actually have the information they need to make a judgement. We should want to make people’s lives better as they themselves understand ‘better’, not according to a single measure we’ve decided on, like lifespan.

So telling people that sugar makes them fatter may be a good policy, if they didn't already know that. And policies that do that do seem to make people more informed. But what’s interesting is the impact they have on people’s diets – usually not much, and sometimes an unexpected one.

For example, a 2008 study found that people who used nutrition labels had big increases in fiber and iron intake, but no change to their total fat, saturated fat or cholesterol intake. The UK’s ‘five a day’ campaign about fruit and veg was very successful at getting people to think about eating more fruit and veg, but increased people’s intake by an average of 0.3 portions a day (which was not viewed as being a very good improvement). 44 studies of similar campaigns in the US and EU have shown about the same size effect.

To some people that might make it look like we need to do more. To me it looks as if people view the costs of changing their diet to something less enjoyable or convenient as being quite important, and are willing to forgo some level of health to avoid that.

Maybe this tells us something about cigarette regulation too – there is some evidence that smokers actually overestimate the risk of smoking and some that they underestimate it. If they do overestimate the risks, we’re ‘informing’ people so much that it’s become misleading.

It would be fair to respond to this that people have no real way of doing a proper cost-benefit analysis about eating sugary foods or smoking, but because the state can’t measure the benefits – that is, the pleasure – it is just as limited.

The fact that people do change their habits about iron and fibre, but not fats, suggests that they aren’t ignorant, they just don’t want to eat less fat! If that’s the case and we’re working to improve people’s lives on their terms, there is no case at all for more heavy-handed policies like taxes, ingredients restrictions and advertising bans.

It’s time the government let adults - even the smokers - grow up

While the under-12s and orchestras hit the jackpot in yesterday's Autumn Statement, tobacco companies were subtly thrown under the bus, as the Chancellor quietly committed to a consultation to determine how much more money tobacco companies should be contributing to public services; a pledge Labour has already signed on to as well. Specifically, the consultation will look at the “introduction of a levy on tobacco manufactures and importers,” which could raise taxes on tobacco companies by millions of pounds a year.

From the Independent:

The tobacco industry should pay for the costs it imposes on British society, the Chancellor has said, signalling that the Government will back a levy on tobacco manufacturers and importers.

In a low-key Autumn Statement announcement, George Osborne committed the Government to a consultation on how tobacco companies could make bigger contributions to the public purse.

Specifically he said:

Smoking imposes costs on society, and the Government believes it is therefore fair to ask the tobacco industry to make a greater contribution.

The Government will shortly launch a consultation on introducing a levy on tobacco manufacturers and importers.

My colleague Ben has just recently addressed these ‘costs on society’ the Chancellor references, and debunked a fair few of them. He also pointed out the known, positive effects of nicotine, and reminded us that, despite all the lies perpetuated around smoking and NHS spending, smokers, on average, take up less health expenditure over their lifetime than non-smokers do.

My two-cents goes something like this: What cost on society? Sure, there’s a cost on the smoker, who will deal with the consequences that come from inhaling all sorts of questionable stuff – but adults get to make those personal decisions and take those risks. All choices have a cost, but in the case of cigarettes, the individual bears the brunt of the consequences; not the public at large.

But more powerful than the adults trying to make decisions about their personal lifestyles is the government, which is treating cigarettes the same way children tend to treat stuffed animals – labelling them with human-characteristics; acting as if objects are inherently bound to be good or bad.

And when it comes to cigarettes, the government has deemed them inherently evil. And it’s the tobacco companies, of course, that are proliferating them (remember, public demand matters very little to paternalists), so naturally, they must be taxed to the death.

But you know who’s really going to suffer when push comes to shove and levies are imposed? Low earners – who probably will, but can't afford to, see cigarette prices rise when the levy comes into play. Because, at the end of the day, these levies aren't coming in to save public health; they're there to save vulnerable public budgets. It's time the government came clean on that—childish, indeed.

On Ed Miliband's new tax on tobacco profits

Ed Miliband has decided that there should be higher taxes on the profits of cigarette companies. The argument being that smoking costs the NHS money and that thus some cash should come from the one activity to cover the other. However, that activity of smoking already more than covers the public costs associated with it. As is helpfully pointed out here:

Estimates for the amount spent on tobacco in the UK in 2011 range from £15.3bn to £18.3bn. The cost of smoking to the NHS is put at between £2.7bn and £5.2bn.

The Treasury earned £9.5bn in revenue from tobacco duties in the financial year 2011-12.

When even The Guardian is pointing out the mathematical difficulties with a Labour Party leader's promises then it would be fair to say that it's not really going to fly, wouldn't it?

And that is rather the point about smoking. The activity is already sufficiently taxed that it pays for all of the public costs associated with it and more (and that's to ignore the fact that shorter lifespans as a result save the NHS money). There are substantial private costs of course: but public taxation isn't the correct way to deal with such private costs either.

Rolling down a slippery slope

Warnings about ‘slippery slopes’ are often overused by defenders of individual liberty. That’s probably inevitable, since we often end up defending a principle against a seemingly-pragmatic policy that, by itself, is not very objectionable.

For instance, I find it hard to muster any specific argument against energy efficiency labelling of washing machines, but the principle of letting people do what they want with their own stuff means that I’m still pretty suspicious of them. It’s hard to convince someone else who doesn’t already share my belief in that principle without resorting to things like slippery slope arguments .(First they label the washing machines – next it’ll be health warnings on cans of Coca-Cola!)

But, overused as they can be, slippery slopes really do exist. Tobacco regulation is an interesting example, because it's often used as the thin end of the wedge for other kinds of paternalism. After plain packaging of tobacco was passed in Australia (will the new, nominally Liberal government repeal this legislation?), its advocates moved straight on to calls for plain packaging of alcohol. To quote our 2012 paper:

Australian Senator Cory Bernadi recalls: “[O]n the very first day [after the plain packaging legislation was passed] they moved onto drinking. People who were advocating plain packaging were saying “We should have this for alcohol. We should have it in fast food”. Where does it end? The nanny state will never end because there is always another cause to advocate for.”

Some health groups in Australia have also called for plain packaging of ‘junk food’, whatever that is.

So it’s worrying when tobacco is treated as a special case in international trade agreements, as is happening in Trans-Pacific Partnership negotiations between a number of major Pacific Rim countries, including Australia, the US, New Zealand and Japan.

The US and Malaysia have proposed exemptions for domestic tobacco control measures from the provisions of the Partnership. Not many people will object to that on its own, but here’s where the slippery slope problem comes in. Most free trade agreements are riddled with special exceptions, but using them to reinforce domestic paternalism is particularly ugly.

A free trade agreement that institutionalises tobacco as being ‘non-normal’ is a hop, skip and a jump from one that does the same for all sorts of other things that people probably would have a problem with being told are abnormal, like booze. And the infantilization of adults – much harder to pinpoint than the number of lives supposedly ‘saved’ by tobacco control measures – rolls on.
