This article explores the processes that led to the inclusion of psychedelics under the 1971 Convention on Psychotropic Substances, a cornerstone of international drug control. Drawing on archival records, we analyze the narratives and dynamics that shaped this decision. Despite limited scientific evidence of public health dangers, concerns about psychedelics were amplified by sensationalized media focused on their perceived risks, including dependency potential and associations with youth counterculture. The Cold War context influenced international consensus, with Eastern Bloc nations framing drug issues as Western societal failures while Western nations emphasized drug control as a public health priority. While tobacco, alcohol, sedatives, and stimulants benefited from cultural, political, and economic advocacy, psychedelics had no such support, which facilitated their stricter regulation. However, the United States played a pivotal role in preserving allowances for psychedelic research and the use of psychedelic plants, counterbalancing proposals from France and the USSR for more restrictive measures. Building on previous studies in global drug diplomacy, the article underscores the interplay of ideological, cultural, political, and institutional factors in shaping international drug policy.
