It's a discriminatory, anti-progressive tax in that it falls far harder on the poor than the well-off. If its backers were honest, they'd admit the aim of the exercise is to stop poor people smoking since rich smokers clearly won't kick the habit just because it's going to cost them a few extra bucks.
The fact that the increases will raise $425 million in revenue is being touted as a happy byproduct. Not only are politicians and bureaucrats congratulating themselves on screwing revenue out of those who can least afford it, they're having a cynical each-way bet: if it actually doesn't work, we'll get a nice little windfall. In other words, the state is now in the business of taxing addiction.
Over the past few decades, as a Herald editorial pointed out this week, the anti-smoking campaign has largely succeeded with the number of people who now smoke on a daily basis down to 15 per cent of the population over the age of 15.
You might think that was an argument for directing the same level of energy and resources at and imposing similar financial disincentives on other substances that are damaging to the nation's health and well-being: sugary and fatty foods causing the obesity epidemic and alcohol.
I suspect the numbers tell the story: cranking up the price of grog and junk food would affect a lot more people and therefore carry a higher political risk than hammering the dwindling, friendless band of diehard smokers.
Among those adversely affected by an increase in the price of alcohol would be our winemakers, who are routinely portrayed as talented and dedicated artisans in whose output we should take pride. Not so long ago, a leading light in the Maori Party described those who work in the tobacco industry as "terrorists".
But if the issue is the strain imposed on our health and legal systems, it could be pointed out that tobacco isn't a root cause of road accidents, domestic violence or street viciousness of the king hit variety.
I feel particularly sorry for elderly people living in straitened circumstances who took up smoking when it was socially acceptable and the health risks far less evident and for whom it provides some solace in otherwise bleak lives. Is it equitable or humane to offer them the choice of giving up one of the few enjoyable pastimes available to them or taking a cut in their already low standard of living?
But such questions don't prey on the minds of social engineers who believe perfection, in the form of a 100 per cent smoke-free society, is attainable and desirable. It may cause a little short-term suffering - in which they, of course, won't share - for the recalcitrant minority but then you can't make an omelette without breaking a few eggs.
