Roots of addiction debate

There are many different answers for what actually leads to addiction- is it nature?- Something genetic, biological, a disease. Or is it nurture?- the way you were raised, what you learnt growing up, and how you were taught to regulate your emotions?
The reality is that it is a combination of the two and we do not yet know the percentage breakdown of either. So focus on which definition is the most helpful for you in your struggles.
