If you think addiction is all about booze, drugs, sex, gambling, food and other irresistible vices, think again. And if you believe that a person has a choice whether or not to indulge in an addictive behavior, get over it. The American Society of Addiction Medicine (ASAM) blew the whistle on these deeply held notions with its official release of a new document defining addiction as a chronic neurological disorder involving many brain functions, most notably a devastating imbalance in the so-called reward circuitry. This fundamental impairment in the experience of pleasure literally compels the addict to chase the chemical highs produced by substances like drugs and alcohol and obsessive behaviors like sex, food and gambling.
The definition, a result of a four-year process involving more than 80 leading experts in addiction and neurology, emphasizes that addiction is a primary illness—in other words, it’s not caused by mental health issues such as mood or personality disorders, putting to rest the popular notion that addictive behaviors are a form of "self-medication" to, say, ease the pain of depression or anxiety.
