If you are like many Americans, you drink alcohol at least occasionally. For many people, moderate drinking is probably safe. It may even have health benefits, including reducing your risk of certain heart problems. For most women and for most people over 65, moderate drinking is no more than three drinks a day or seven drinks per week. For men under 65, it is no more than four drinks a day or 14 drinks per week.
Some people should not drink at all, including alcoholics, children, pregnant women, people taking certain medicines, and people with certain medical conditions. If you have questions about whether it is safe for you to drink, speak with your health care provider.
Anything more than moderate drinking can be risky. Heavy drinking can lead to alcoholism and alcohol abuse, as well as injuries, liver disease, heart disease, cancer, and other health problems. It can also cause problems at home, at work, and with friends.
