Abstract: The majority of smoking cessation research has focused on heavy smokers. African Americans (AA) are less likely than the general population to be heavy smokers. Thus, little is known about the smoking and psychosocial characteristics of lighter AA smokers. The present study compared the baseline demographic, smoking, and psychosocial characteristics of light (5–10 cigarettes per day; n =86) and moderate to heavy (>10 cigarettes per day; n =286) AA smokers enrolled in a smoking cessation clinical trial. Results indicated no differences between groups on demographic variables. However, light smokers (LS) were less dependent on smoking, reported more previous quit attempts, and had higher self-efficacy to quit than moderate to heavy smokers (MHS). On a measure of withdrawal, LS reported less pre-quit craving and less difficulty concentrating than MHS. In addition, LS reported lower perceived stress, fewer symptoms of depression, and greater positive affect than AA MHS. These findings highlight important similarities and differences between AA LS and MHS, and have implications for the treatment of AA smokers. [Copyright &y& Elsevier]
