Philosophers study addiction because it poses a problem in which our judgments over what we should do are supposed to have some power over our actions. Addicts frequently use drugs despite claiming that they would prefer not to use them, or that they know it would be better if they abstained. 

The philosophical challenge is to explain why the preferences and intentions of addicts seem to come unglued from their addictive choices. However, addiction is also a case that must fit into a broader philosophical discourse about self-control, desire, free will, agency, and responsibility in non-addicted people. 

How do our desires rob us of control or of rationality?

What are you addicted to? How does it help/hinder? What are your thoughts on addiction? How does it contribute to your art?
