Especially at low and moderate drinking levels, alcohol consumption can be associated with benefits (e.g., protection against coronary heart disease) as well as risks (e.g., increased risk of accidents). These benefits and risks may change across a person's life span. To determine the likely net outcome of alcohol consumption, one must weigh the probable risks and benefits for each drinker. These assessments are based on the individual drinker's consumption levels, his or her personal characteristics (e.g., age or preexisting risk factors for coronary heart disease), and subjective values as well as on social considerations. The validity of such assessments also depends on the accuracy with which alcohol consumption and alcohol-related consequences can be measured. (A)
