Cannabis: Global Histories is a 2021 edited volume on the global history of cannabis, edited by Lucas Richert and James H. Mills and published by the MIT Press. It collects fifteen essays and an editors' introduction tracing cannabis consumption, commerce and control from the early nineteenth century to the present, with case studies drawn from Africa, Asia, the Americas, Europe and the Middle East.

The volume argues that Western colonialism shaped and spread ideas about cannabis in the nineteenth century that came to drive the international drug control regimes of the twentieth, and that the more recent growth of commercial cannabis interests has unsettled that consensus. read more →

Knowledge translation and evidence use in medicinal cannabis policy: An evidence brief on regulation, effectiveness, safety and stakeholder support in Colombia

A knowledge-translation study from the Unit of Evidence and Deliberation for Decision Making at the University of Antioquia in Medellín, reporting how an evidence brief on the regulation, effectiveness, safety and stakeholder support of medicinal cannabis was assembled and put before Colombia's Ministry of Health. Its interest for the corpus is procedural rather than botanical: it documents how research evidence and stakeholder opinion were marshalled into a national cannabis regulatory process, in a producer country whose policy record the wiki otherwise holds through enforcement reporting.
