Study sheds light on source of drug addicts risk-taking behavior

New insight has been gained into how the brains of drug addicts may be wired differently. The findings show that while drug users have very strong motivation to seek out 'rewards,' they exhibit an impaired ability to adjust their behavior and are less fulfilled once they have achieved what they desire. This disconnect between the craving for a drug and inability to regulate behavior may be key to breaking the cycle of addiction.
