Addiction Defined as Brain Disease

New research shows that substance abuse is not a weakness of character or a choice but a clinical disease in need of professional treatment.

It’s official: the American Society of Addiction Medicine (ASAM) has officially recognized that addiction is not solely related to substance misuse and is, in fact, a chronic brain disease.

For decades, addiction specialists and those battling substance abuse have had to fight against the stigma that addiction is some sort of character flaw or personal weakness. But experts have long known that “at its core, addiction isn't just a social problem or a moral problem or a criminal problem. It's a brain problem whose behaviors manifest in all these other areas," ASAM Past President Michael Miller, MD, said in a news release.

"The disease is about brains, not drugs. It's about underlying neurology, not outward actions," added Dr. Miller, who oversaw the development of the new addiction definition.

This new definition of addiction was based on findings from brain circuitry studies prompted by more than 80 experts who came together four years ago to begin the process. Previous research has shown that addiction affects neurotransmission in the reward area of the brain, triggers craving of addictive behaviors based on memories of previous experiences, and alters areas that govern impulse control and judgment.

Addiction Definition

Highlights of the new definition include a description of addiction as a primary disease, which means “it's not the result of other causes such as emotional or psychiatric problems.” ASAM also notes that addiction is a chronic condition, and so should be treated, managed and monitored over a lifetime. The new definition also acknowledges that the disease drives behaviors that others might not understand. It also makes clear that addiction is not a choice, even though choice plays an important role in getting help.

Experts hope this new definition will help decrease the stigma of addiction. By decreasing the stigma, treatment professionals believe it will lessen the barriers to individuals getting the help they need.
