This article analyses how the Chinese Communist Party (CCP) created and spread new forms of subjectivity and social belonging in the formative years of the People’s Republic of China (PRC) (1949–present). Specifically, it examines how the CCP blended medical and emotional discourses to foster communal hatred of narcotics users and promote social cohesion. Building on scholarship that conceptualizes hatred as a way of producing and animating subjectivity, the article argues that the CCP saw it as a key tool of unification, bringing people together to commit acts of emotional and physical violence against drug users and traffickers. Propaganda officers and police forces worked hard to persuade people to hate drug users and traffickers, writing anti-narcotics songs, plays, and skits to make hating an entertaining and interesting activity for audiences. The article underscores how the CCP encouraged mass participation in the ostracizing and killing of narcotics producers, consumers, and traffickers to spawn a shared social hatred of them, and shows how people responded to state efforts to incite hate. To conclude, the article considers the unlikely agency of some accused drug criminals who resisted the tides of public and state pressure, and challenged their accusers.
