However a major limitation of this finding is that such individuals can account for only a small percentage of those with alcohol problems. Since the majority of alcohol abusers do not have a family history of alcohol problems, environmental factors also contribute significantly to the development of alcohol problems. In summary, while some drinkers are at greater risk than others, anyone can develop alcohol problems. Present evidence suggests that alcohol abusers' drinking careers most often involve periods of drinking problems of varying severity, separated by periods of abstinence or of drinking without problems. Only a minority experiences a progressive, lock step worsening of problems.
People drink heavily for a variety of reasons.
This short term rewarding effect is thought to be one reason why people are willing to risk the long-term negative consequences of heavy drinking. However, most treatments have shown only limited success. Even the topic of treatment goals is controversial. Research conducted over the past two decades suggests, however, that reduced drinking is an appropriate goal for some alcohol abusers, especially those whose problem is not severe. Some recent evidence also indicates that some alcohol abusers recover without formal help or treatment.
