Completely missing from the article is an estimate of the coupling between drug and non-drug crime (e.g. prostitution or robbery to finance a drug habit, violent conflict vertically and horizontally along the supply chain, tax avoidance, and corruption of police and other government employees). There are also tertiary effects, like drug gangs engaging in additional illegal activities supported by the core competencies of trafficking and violence. This merits an additional study.
