In the several years that I have been around the rooms of various 12 step fellowships, it has been my experience that addiction is addiction is addiction. I have met people who are addicted to drugs, alcohol, food, gambling, love, relationships, chaos etc, etc. The truth is that people will addict to anything that takes them out of themselves. While I don't claim to know the reasons why people do so of one thing I am sure, it doesn't really matter what people find that does the trick for them addiction is about avoiding having to face yourself - your true self.
