Alcohol genetics: will the promise be fulfilled?

Genetic research into alcohol-related problems has a long history, but only with the recent advent of molecular biological techniques does it seem poised to fulfill its promise. While such research might be thought to reinforce views of the inevitability and immutability of dr inking problems, there have been bold promises of important developments in our understanding of the aetiology of alcohol misuse, as well as promises of innovations in prevention and treatment. A brief consideration of recent research, and of the possibilities that are now before us, reveals that the promise of increased understanding of the aetiology of alcohol misuse is already being fulfilled. Promises of new preventive and therapeutic interventions, if they also are to be fulfilled, require that a number of practical and ethical issues be addressed. Clinicians, researchers and others in the addictions field need to begin to address the ethical issues that are raised.
