Cannabis ruderalis Janisch. is a name applied to wild and weedy cannabis populations of temperate Eurasia, formally described as a separate species by the Russian botanist Dmitri Janischewsky in 1924 on the basis of plants collected along the lower Volga River system. The epithet derives from the botanical Latin ruderalis, "growing among waste": a ruderal species is one that colonises ground disturbed by human activity or natural agents.

The species status of C. ruderalis has been debated since publication of the name. Janischewsky himself recorded that he was "inclined to consider it a well marked variety" rather than a full species, and the most widely applied formal treatment, Small and Cronquist (1976), reduced the ruderalis concept to Cannabis sativa subsp. sativa var. spontanea Vavilov, a name with priority over C. ruderalis at the rank of variety, having been published by Vavilov in 1922. Three-species treatments after Schultes et al. (1974) retain C. ruderalis at species rank, while recent molecular work consistently supports the monotypic Cannabis sativa L. with ruderal forms … 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.
