This can and does result in errors of perception regarding one’s ability or (lack of) impairment, and in decisions and judgments that themselves lead to risky consequences.
Chronic risk, on the other hand, has to do with the long-term effects of drinking.
Heavy drinking is closely linked to a wide range of health problems, at least doubling the risk for heart disease, cancers of many types, and hypertension.
Risks for liver disease and for cancers of the mouth and gastrointestinal system are greatly increased by drinking above moderate levels.
At the same time, it is abundantly clear that heavier drinking is often associated with devastating consequences to the individual and to society.
Wine has long been recommended to promote physical health, and indeed recent scientific evidence indicates a consistent association between moderate drinking and longevity, although the reasons for this link are still poorly understood.Next are moderate problem-free (“normal”) drinkers. The average consumption for this large group is about three or four drinks per week.They fall largely within the limits for safe drinking recommended by the National Institute on Alcohol Abuse and Alcoholism: not more than two drinks per day for men, and not more than one drink per day for women, with some alcohol- free days each week.What is the normal course of human development with regard to alcohol?The answer to this question is quite specific to culture.Because alcoholic beverages differ in content, it is important here to define what constitutes “one drink.” A useful definition is that one standard drink contains one-half ounce of ethyl alcohol.When moderation is exceeded, or when one drinks at all in dangerous situations, one enters the realm of risky drinking, which includes both acute and chronic risk. Conclusion In order to understand the problematic use of alcohol, it is helpful first to consider what constitutes a state of health with regard to its use.Such people obviously have no negative consequences related to their own drinking.The only safe blood alcohol level behind the wheel is zero.A small amount of impairment from intoxication can also be lethal when combined with activities such as water sports, skiing, hunting, climbing, or using power tools, where minor misjudgments can have major consequences.
