According to a survey held by the British Action on Smoking and Health (the ASH, for short), 20 percent of the British adults smoke. Is this a good thing? I don’t know. I believe that the act of smoking isn’t intrinsically good or bad; it is something that each person should decide for himself. However, what I do believe is valuable in its own right is human autonomy. By autonomy I mean ‘the right each person has to decide for himself how to live his life without unjustified intervention from external parties‘. And it is this latter point I want to draw attention to.

According to the ASH, in 2012, 77 percent of the price of a pack of cigarettes consisted of tax. Multiply that by the number of cigarette packs sold, and you get an amount of £10,5 billion raised through tobacco taxation. This is six times as much as the spending by the the National Health Service (the NHS) on tobacco related diseases; these were ‘merely’ £1,7 billion. So the question that comes to mind is: what justifies the £8,8 billion that remains after subtracting the NHS costs from the money raised through tobacco taxation?

The ASH claims that the inequality between the two numbers is no issue, for ‘tobacco tax is not, and never has been, a down payment on the cost of dealing with ill health caused by smoking’. But what then is the purpose of this tax? The ASH claims that the high level of tobacco tax in Britain serves two purposes: (1) to reduce smoking through the price incentive, and (2) to raise taxes from a source that has little impact on the economy. The latter point has been scrutinized extensively by economists, and I don’t think I can add anything to that discussion. So let’s focus on the first point: the aim of reducing smoking through the price incentive.

By making this claim, the ASH implicitly assumes that it is within the government set of rights to reduce smoking among its citizens. But is it? One can justify tobacco taxation on the grounds of the (health care) costs incurred by the non-smoking part of society. But, as we have seen, this amount by no means adds up to the taxes levied on tobacco. I believe this question (‘But is it?’) directs us towards the fundamental question of where the boundaries lie between justified government intervention and morally objectionable behaviour. One could say that, as I believe, it is one thing (and justified) to prevent non-smokers from being financially hurt by the actions of smokers, but that it is a completely different thing (and not justified) to promote non-smoking values among citizens, merely for the sake of – what appear to be – paternalistic motives.

As with any government intervention, the benefits of the intervention should be weighed against its costs. Presumed that there might be an intrinsic value in having a non-smoking society – a point the ASH doesn’t provide any argument for – the costs of violating what might be an intrinsically valuable human right (autonomy, that is) should be included in the calculation as well. And until this has been done, the question of whether the £10,5 billion in tobacco taxation is justified remains open for debate.

But what do you think?
