A profile of tobacco smoking

Cigarette smoking has for years been declining slowly in a number of major Western countries. It nevertheless remains highly prevalent, with one-quarter to one-third of adults being current smokers in the USA and Britain, and only some 40 per cent of those who have ever smoked cigarettes regularly have given up. Smoking is increasingly becoming a marker for deprivation and for a stressful life-style, and is also associated with consumption of other drugs. There is abundant and convincing evidence that, far from being confined to a minority of problem users, high levels of dependence on tobacco are experienced by a majority of smokers in the general population, with an onset early in the smoking career. The rewards which underpin continued smoking are unclear, but it may be that avoidance of the unpleasantness of not smoking is more significant than positively rewarding effects.
