In America, alcohol use extends far beyond the limits of drug use. In 2005, 51% of all Americans consumed alcohol in  one month, according to the National Survey on Drug Use and Health. But alcohol overuse presents just as serious a problem as the worst drug addiction.

Alcohol consumption becomes alcohol dependence or alcoholism when it creates problems and damages lives but these effects are ignored. Alcohol dependence indicates that there is an addiction to alcohol and that a person must find and consume alcohol to feel good or normal, be comfortable around other people, enjoy life, etc.

An alcohol addiction is a condition characterized by repeated, compulsive seeking and use of alcohol despite adverse social, mental or physical consequences. It is usually accompanied by psychological and physical dependence on alcohol and the appearance of withdrawal symptoms when it is rapidly decreased or terminated.

When addiction exists, the alcohol use controls the individual rather than the individual controlling the alcohol use. In 2005, more than 23 million Americans were estimated to experience alcohol abuse. More than ten million Americans were dependent on alcohol.

Adverse effects resulting from alcohol use include failing to remember conversations or commitments, blacking out, experiencing health problems or injuries, losing prior interest in activities and hobbies that used to bring pleasure and having legal problems or problems with jobs, relationships, employment or finances. When alcohol consumption continues despite these effects, the situation meets the definition of addiction.
