Disciplined Passion

Aristotle introduced the idea of disciplined passion, which is essentially living with both reason and passion. He denounces a purely hedonistic life, however, he does seek a life of pleasure, exercising it through reason. I would like clarification on one thing. The book uses the example of a drug addict being happy with a supply of drugs. However, a drug addict can still experience pleasure with his or her lifestyle. Isn't a drug addict using his or her own twisted reason while taking pleasure in drug use? Therefore, can a life of pleasure be exercised through incorrect reason or it is still just a purely hedonistic life?
