This study investigates the impact of a variety of sociodemographic, behavioral, and contextual risk factors on cigarette use, abstinence success, and intentions to quit based on a survey of active-duty military personnel in Taiwan. Being male and of lower educational background increased the likelihood of tobacco use. About 80% of current smokers showed intention to quit in the immediate future, whereas stress and depression were leading causes for cigarette smoking and relapse. Other prominent predictors include attention to antismoking advertising, health concerns, social pressure, and support for a tobacco-free military. Implications for effective antismoking campaigns in the Taiwanese military are discussed.
