Addiction may be defined as a pattern of behavior that's persistent, the result of a psychological or physical dependency that disrupts a person's quality of life. People become addicted to a wide variety of substances -- in the realm of physical addiction, a person could be addicted to tobacco, narcotics, alcohol, sedatives and stimulants; in psychological addiction, the person might take ordinary drives, such as the need for food or sex, and take these behaviors to an extreme. Everyone knows someone with an addictive streak or an actual addiction, but how do these addictions come about?
