I don't think that @way meant the term in anyway to be offensive, and I certainly did not find it offensive, and am a little confused as to why anyone would.
If it was used in a derogatory context, I could understand it, but it wasn't.
I do understand the concept of language mattering, like how the terms "clean", and "dirty" add to the negative connotations of addiction.
I think there is a fine line between getting over the point that the words we use matter, and finding every other word said about addiction or addicts as offensive.
This is not a dig at anyone, just MHO.
