In this second edition of his groundbreaking work, John Booth Davies expands and updates his highly acclaimed study of the true reasons for drug use.

Current attitudes towards drug misuse in the media, government and even treatment centres, often exaggerate the pharmacological power of drugs. Their coercive influence is widely believed to be so great that to experiment with a drug is tantamount to addiction.

Davies argues that such beliefs are largely inaccurate and harmful. Research shows that explanations for drug use vary according to circumstances. Drug users may explain that they have lost their willpower and capacity for personal decision-making, because this is the explanation expected of them, but most actually use drugs because they want to and because they see no good reason for giving them up. Addicted behaviour is therefore a form of learned helplessness, not an effect caused by narcotic intake.
