This blog is intended to discuss the psychological and behavioral aspects of addiction. Addiction is a disease (dysregulation) of parts of the limbic system of the brain. This dysregulation of dopamine and other neurochemicals creates a pattern of compulsive use of substances. This compulsion and the mood alterations that accompany the use of addictive substances leads to behaviors and consequences that are almost always negative for the individual and those around them. Historically, addiction is viewed pejoratively by society. In fact, it is an illness that requires treatment.
