Project 3, Study 2: Extended Exposure to Low Nicotine Content Cigarettes in People With Current Affective Disorders
This study will examine extended exposure to cigarettes varying in nicotine content among
 people with affective disorders. People with affective disorders are at an increased risk for
 smoking, nicotine dependence, and using high nicotine yield cigarettes and are also at
 significantly increased risk for smoking-related adverse health consequences. Studies testing
 an innovative regulatory strategy of reducing the nicotine content of cigarettes to a
 non-addictive level have shown promising beneficial effects (decreased smoking rate, reduced
 toxicant exposure, and increased cessation) in the general population of smokers. However,
 these studies have uniformly excluded vulnerable populations like people with current
 affective disorders, who may respond differently considering their greater vulnerability to
 smoking and nicotine dependence. Thus, little is known scientifically about how this highly
 vulnerable subgroup of smokers may respond to a nicotine reduction policy. This project is
 designed to fill that substantial knowledge gap.
