Diamba is a vernacular name for cannabis documented in western Central Africa, in Sierra Leone and in Brazil. Closely related recorded forms include riamba, liamba and chamba. Brian M. du Toit treated them as a western African naming complex, centred on the Congo basin and northern Angola, while later work has associated the forms with Kimbundu and their transfer into Brazilian usage.

The form diamba appears as the headword for Cannabis sativa in J. Gillet and E. Pâque's 1910 flora of the Kisantu region. The same source records diamba di nseke, "savanna hemp", for a different plant that resembles cannabis. The name therefore has to be read with its qualifier and botanical identification where one is supplied.

An 1851 notice from Sierra Leone describes the plant under this name among people brought there from the Congo. Dictionaries record forms of the name in Kikongo (1887) and in Kimbundu. Accounts of the name's origin differ. … 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.
