Untreated drug and alcohol use contribute to tens of thousands of deaths every year and impact the lives of many more. Healthcare already has effective tools including medications for opioid and alcohol use disorder that could prevent many of these deaths, but they are not being utilized widely enough, and many people who could benefit do not even seek them out. One important reason is the stigma that surrounds people with addiction.

Stigma is a problem with health conditions ranging from cancer and HIV to many mental illnesses. Some gains have been made in reducing stigma around certain conditions; public education and widespread use of effective medications has demystified depression, for instance, making it somewhat less taboo now than it was in past generations. But little progress has been made in removing the stigma around substance use disorders. People with addiction continue to be blamed for their disease. Even though medicine long ago reached a consensus that addiction is a complex brain disorder with behavioral components, the public and even many in healthcare and the justice system continue to view it as a result of moral weakness and flawed character.
