Did you realize there's a difference between "addiction" and "chemical dependence"? You can be chemically dependent (on drugs or alcohol, etc.) but not be addicted to those substances; one doesn't necessarily mean the other.
Addiction carries with it a psychological attachment that chemical dependence doesn't.
It took a little while for the distinction to sink in, but once it did, it made a lot of sense...especially as I thought about people in my life who've suffered with one or the other...or both.
