Four barriers and a set of values that prevent violence among cannabis growers.

Background: Cannabis markets are often described as less violent than other drug markets. Domestic cannabis cultivation markets seem to be especially non-violent. However, few studies have investigated why this might be.

Why small-scale cannabis growers stay small: five mechanisms that prevent small-scale growers from going large scale.

Background: Over the past 15-20 years, domestic cultivation of cannabis has been established in a number of European countries. New techniques have made such cultivation easier; however, the bulk of growers remain small-scale. In this study, we explore the factors that prevent small-scale growers from increasing their production.
