My exhusband is addicted to pot, alcohol, blame, resentment, manipulation, and self pity (we've been divorced for 30 years). My son is an addict (currently in recovery) and his DOC is meth and occasionally heroin. I used to refer to his DOC as "more" because it really didn't matter what it was...as long as there was more.
I have many friends who are recovering addicts.
