Initial screening shows that 80% of people are at low risk for alcohol abuse and do not require further screening. High-risk drinking, which is defined as more than 4 drinks per day or 14 drinks per week for men and more than 3 drinks per day or 7 drinks per week for women and those over 65, can lead to social, legal, medical, domestic, employment, and financial problems as well as reduced life expectancy and increased risk of accidents and death from drunk driving. Consuming any amount of alcohol during pregnancy can cause serious birth defects.
