We've always called nicotine (cigarettes), coffeine and alcohol dependence an addiction as well, so I don't think they're really redefining the term. Even adrenaline addiction has been named in medical context, and that's produced by our bodies - not ingested/injected. There really should be a specific term for the physical dependence you're talking about which can end in serious medical issue if the person just quits cold turkey though. It would make sense to differentiate this hard dependence.
