Brain links weakened by nicotine withdrawal may explain smokers' relapse

A new brain imaging study published in JAMA Psychiatry suggests that the high rate of relapse among smokers trying to quit may be due to an inability - brought on by nicotine withdrawal - to switch from the "default mode" brain network, to the "executive control" brain network.The researchers, from the University of Pennsylvania in Philadelphia and the National Institute on Drug Abuse (NIDA) in Baltimore, MD, explain that when the default mode is engaged, people tend to be in so-called introspective or self-referential states.
