Alcohol abuse means having unhealthy or dangerous drinking habits, such as drinking every day or drinking too much at a time. Alcohol abuse can harm your relationships, cause you to miss work, and lead to legal problems such as driving while drunk (intoxicated). When you abuse alcohol, you continue to drink even though you know your drinking is causing problems.
If you continue to abuse alcohol, it can lead to alcohol dependence. Alcohol dependence is also called alcoholism. You are physically or mentally addicted to alcohol. You have a strong need, or craving, to drink. You feel like you must drink just to get by.
