Analyzing addiction: Where Charlie Sheen can go from here

(NECN) - Joining NECN to talk about the impact Sheen's recent actions will have on his career and family was Joe Tecce, an associate professor of psychology at Boston College.

He says Sheen appears to be very confident of himself in some ways, and thinks he can beat the system. The jerky head movements in recent interviews can mean that he's significantly agitated.

Tecce calls Sheen's recent actions the "results of a longstanding battle between himself and drugs."
