May 2013 Men benefit more than women from nicotine replacement therapy for smoking cessation because nicotine affects a key neuroreceptor differently in the two sexes, a NIDA-sponsored study suggests.

April 2012 Dr. Volkow discusses NIDA’s efforts to develop effective antismoking treatments for populations with persistently high rates of smoking, such as people with psychiatric disorders, high school dropouts, and Native Americans.

The analysis also tentatively implicates several genome locations that have not previously been associated with smoking behaviors.
Smokers who switch to cigarettes with very low nicotine content may experience mild and transient increases in some withdrawal symptoms. Cigarettes with reduced nicotine will be easier to quit than the cigarettes marketed at present.
