“The brain adapts and responds to the environments and conditions in which a person lives. When we speak of addiction as a chronic disorder of the brain, it thus includes an understanding that some individuals are more susceptible to drug use and addiction than others, not only because of genetic factors but also because of stress and a host of other environmental and social factors in their lives that have made them more vulnerable.
Opioid addiction is often described as an “equal opportunity” problem that can afflict people from all races and walks of life, but while true enough, this obscures the fact that the opioid crisis has particularly affected some of the poorest regions of the country, such as Appalachia, and that people living in poverty are especially at risk for addiction and its consequences like overdose or spread of HIV. The Centers for Disease Control and Prevention (CDC) considers people on Medicaid and other people with low-income to be at high risk for prescription drug overdose.
Some of the reasons have to do with access and quality of health care received by people in economically disadvantaged regions.”
