Well being a slave to sin goes much deeper than just an addiction. Being a slave to sin requires a heart operation that only God can do before someone can even cry out for help. But this gets into a much deeper debate than I have time for.
Ezekial 36:26
And I will give you a new heart, and a new spirit I will put within you. And I will remove the heart of stone from your flesh and give you a heart of flesh.
