Nicotine has been shown to have effects on brain dopamine systems similar to those of drugs such as heroin and cocaine- Report of the Scientific Committee on Tobacco and Health. Department of Health, 1998.
Recent information concerning dopamine, a neurotransmitter associated with pleasure and well-being, indicates that cigarette smoke might use both techniques for raising dopamine levels. Nicotine has long been known to stimulate the release of dopamine. Now, research by scientists at
Brookhaven National Laboratory (BNL) in New York points toward -- but does not prove -- another mechanism for cigarette addiction. They've found something in cigarette smoke that seems to be slowing the breakdown of dopamine.These brain slices show levels of the "killjoy" enzyme MAO B in the brains of two people. The non-smoker at the top has plenty of MAO B, but the smoker at bottom has much less -- a sign that something in cigarette smoke is destroying MAO B, allowing the pleasure chemical dopamine to tell the body it likes smoking and wants to continue.
