Addiction - Definitions, Heritability In Humans, Models Of Addiction

alcoholism role substance genetics

Addiction in its broadest sense can be defined as the habituation to a practice considered harmful. A more narrow definition of the term refers to chronic use of a chemical substance in spite of severe psychosocial consequences. Terms such as "workaholic," "sex addict," and "computer junkie" arose to describe behaviors that have features in common with alcoholism and other substance addictions. The most convincing data supporting a role of genetics in addiction has been collected for alcoholism, although genetics most likely has a role in other forms of addiction.

What's being taught in the program leading to an A.S. in Addiction Studies at Portland Community College is that addiction is defined as use beyond intent and/or with severe psychosocialbiological consequences. This is distinguished from physical dependence.
