Feral and ruderal Cannabis refers to populations of the cannabis plant (Cannabis sativa) that grow outside cultivation, whether as escapes from former hemp or drug growing that have become self-perpetuating (feral) or as colonisers of ground disturbed by human activity (ruderal). In Cannabis the two descriptions overlap heavily: most naturalised stands are both feral in origin and ruderal in habit, and the same populations are often labelled by either term.

Ruderal is an ecological category, a ruderal species being one that colonises disturbed, nutrient-rich and open ground, while feral is a statement of origin, a domesticate that has reverted to unmanaged growth. Populations of this kind tend to re-acquire or retain a wild-type syndrome of small stature, sparse branching, seed dormancy and readily shattering achenes that sets them apart from the crop they descend from.

This article treats feral and ruderal Cannabis as an ecological and population phenomenon. … 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.
