"Addict'" is one of those words that so many of us use, largely without pausing to wonder if we should. We just take for granted that it's totally OK to describe a human being with one word, "addict" -- a word with overwhelmingly negative connotations to many people.
That addiction is a disease means that we can do something about it, to prevent it, to treat it and take responsibility to self-manage it. David Sheff captures this eloquently in his book, and I work each day to spread the message that successful treatment and recovery are possible.
Gary Rivlan notes in his book, Broke USA, "the working poor have become big business." You wouldn't think that poor people would be a growth market, but businesses make big money off people who live paycheck to paycheck.
