In the past 50 mg tenormin sale, public concerns about the damaging consequences of alcohol excess for the individual and society were expressed in the 46 THE REGULATION OF LIFESTYLE temperance movement order tenormin 50mg visa. Closely aligned with evangelical Christian- ity, temperance campaigners regarded drunkenness as a moral failure and presented abstinence as the route to personal redemp- tion. The anti-alcohol initiatives of the past decade have revived the puritanical spirit of the temperance movement, but in a modern, medicalised, form. Alcohol dependency is now regarded as a disease, though one affecting a growing proportion of the population. Whereas the old temperance movement was dedicated to rescu- ing the ‘habitual drunk’, the medical temperance movement shifted the focus of attention, first from the ‘alcoholic’ to the ‘problem drinker’, and then to the whole of society. The key to this transition was the adoption of the system of calculating alcohol consumption by units. In 1979 the Royal College of Psychiatrists first indicated that a weekly consumption of more than 56 units of alcohol was the ‘absolute upper limit’. In 1984 the Health Education Council suggested that weekly levels of between 21 and 36 units for men, and 14 and 24 units for women, would be ‘unlikely to cause damage’. Then in the late 1980s a new consensus emerged from the royal colleges and other medical bodies, setting the upper limits at 21 for men and 14 for women that have been the basis of most subsequent guidelines (RCPsych 1986; RCGP 1988; RCP 1987; Medical Council on Alcoholism 1987). Three things are worth noting about the process of quantifying alcohol consumption. The first is its arbitrary character: there is no strong scientific evidence for any of these figures, which are simply based on extrapolating from studies relating levels of alcohol consumption to manifestations of disease among heavy drinkers to the rest of society. The second is the trend for the limits to become tighter, a trend more related to the increasing sobriety of the wider political climate than to the emergence of epidemiological evidence justifying a more abstemious policy. The third is that, according to the 21/14 criteria, more than a quarter of men and more than one in ten women in Britain are drinking excessively.
