Calling someone a junkie was once the norm, but many people who use illicit drugs and those who treat them say the word addict is just as stigmatizing. At the Crosstown Clinic, which provides pharmaceutical heroin treatment for people hooked on the opioid, someone has crossed out “addicts” on a notice posted by a group called the Addicts Union and substituted “patients.” Dr. Scott MacDonald, lead physician at Crosstown, said the Diagnostic Statistical Manual of Mental Disorders no longer lists the term addict. People who chronically use illicit drugs are now considered to have a substance-use disorder, not an addiction, which is more stigmatizing.
