Not only does alcohol abuse have serious consequences for physical and psychic health, it is also destructive of personal and social relationships. But putting an end to this form of drug abuse is particularly complex, because alcohol creates a dependence that is both physical and psychological, and because it is, in many cultures, closely linked to sociability. In trying to help alcohol abusers who wish to stop drinking, one is often confronted with resistance and denial. The authors, specialists in cognitive and behavioural therapies, describe methods that have been successfully used for many years in the treatment of alcohol abuse in a hospital setting.
