Some people should not drink at all, including alcoholics, children, pregnant women, people on certain medicines and people with some medical conditions. If you have questions about whether it is safe for you to drink, speak with your healthcare provider.
Anything more than moderate drinking can be risky. Binge drinking - drinking five or more drinks at one time - can damage your health and increase your risk for accidents, injuries and assault. Years of heavy drinking can lead to liver disease, heart disease, cancer and pancreatitis. It can also cause problems at home, at work and with friends.
