Low Dopamine Levels Linked To Relapse For Ex-Smokers

Low Dopamine Levels Linked To Relapse For Ex-Smokers

Research undertaken by scientists at Baylor College of Medicine takes big steps in helping to explain why it is so hard for smokers to quit their addiction. Smoking enhances dopamine release, and when a smoker attempts to quit, dopamine levels lower significantly. The lapse in dopamine levels can prompt a relapse for smokers who are trying to quit. The authors suggest medications which could elevate dopamine levels when a smoker is trying to quit, could be key to a non-smoking life style and help to prevent relapse.
