Addicts like us are great at inventing rationalizations (otherwise, we wouldn’t be able to continue our self-destructive behavior), and a big part of recovery is getting honest with ourselves and rooting out those rationalizations.
One of our favorite rationalizations is “it’s just a bad habit.” And while it’s true that habit is a big component of smoking, and I don’t think anyone would argue that smoking is a bad habit, it’s much more than that: the primary reason we smoke is because we’re addicted to nicotine.
