In this study, we analyzed identity construction among young smokers in China, with three interconnected objectives: to theorize the turning points and career trajectory of smoking initiation; to account for their characteristics with interactionist processes; and to critically evaluate the applicability of classic typologies of identity change by Becker and Strauss. In-depth interviews with 24 late adolescents (ages 18–19) revealed a smoking initiation career path of four interconnected turning points, each characterized by interactionist processes. Smoker peers played a key role in facilitating overall career progression, and shame avoidance was crucial to their social dynamics. We also conclude that classic studies of turning points in general, and substance use specifically, are sufficiently broad and flexible to elucidate tobacco smoker identity construction in China, and facilitate a comparison of commonality and divergence among different “becoming” identities. The implications of these findings for tobacco control in China are discussed.
