iatrogenic addiction
addiction caused by medical treatment (e.g., liberal use of opiate analgesics in a hospital setting or by a physician that leads to opiate addiction).
I went in for back surgery and they kept giving me morphine. Now that I was sent home they gave me a prescription for OxyContin. I just can't seem to stop taking them. Now my doctor says that I have iatrogenic addiction. WTF am I supposed to do now?
