Cannabis is the most widely consumed illicit drug globally, with around 219 million users in 2021, according to the UNODC. It is also the illicit drug that is being legalized most rapidly for medicinal or recreational use. While Colombia has taken steps toward regulation, such as legalizing medicinal cannabis in 2015, the complete legalization of recreational cannabis is still under discussion. 

This report draws on experiences from countries like Uruguay, Canada, and the United States, which have already implemented cannabis legalization, to explore the possible outcomes for Colombia. It concludes that while legalization could reduce the size of the illegal cannabis market, a grey market supplying both local and international demands is likely to persist.  

A key focus is on how criminal control over cannabis production areas could hinder the transition of growers to a legal market. The report emphasizes the need for coordinated cannabis regulatory and security policies to protect small-scale and traditional growers and integrate them into the legal market. Furthermore, the potential for reduced violence is explored, though the report notes that this is unlikely to happen immediately. Criminal groups may resist the establishment of a legal market, leading to short-term increases in violence as they compete for control over remaining illicit markets. 

Another significant finding is the potential transformation of Colombia’s criminal justice system. Legalization could free up resources, allowing law enforcement to prioritize more serious public safety issues and reducing low-level cannabis prosecutions and prison overcrowding. 

This report offers crucial insights for policymakers, emphasizing that while cannabis legalization is not a cure-all for crime and violence in Colombia, it is a critical step toward more effective drug policy reform and organized crime reduction.
