But, of course, alcoholism or alcohol dependency isn't the only public health problem that exists in Wales. There's a significant problem with obesity, there's a significant problem with cardiovascular disease, and the Public Health Wales Observatory has recently published figures that show that the risk factors for heart disease are: physical activity, 71 per cent; unhealthy eating, 67 per cent; alcohol, perhaps surprisingly, only 43 per cent; and being a current smoker, even more surprising, only 23 per cent. So, where is this policy of minimum pricing of alcohol going? If the state has allocated to itself the power to try to alter people's behaviour in their private lives by using the tax system or a variant upon it, why shouldn't we introduce a tax on food, a tax on salt, or any other of the known factors that might be a cause of deterioration in individuals' health?
