I started reading Breathing Under Water: Spirituality and the Twelve Steps by Richard Rohr, a Catholic priest and recovering alcoholic.
He says we're all addicts, that addiction is just a modern name for sin, or what medieval Christians called passions or attachments.
Addiction is just self-destructive thinking, and everybody has some pattern of thinking that holds them back from maturing spiritually.
It's just that our addiction is more obvious to others because we happen to be physically addicted to a substance.
