The Herbarium has ten sheets of Cannabis sativa filed under number 4665 of Nathaniel Wallich's catalogue, the dated ones gathered between 1796 and 1826. The Economic Botany Collection holds hemp fibre, cordage, seed and a pipe for smoking cannabis from Zululand. 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.
