A study indicated that legalizing recreational cannabis may help decrease the size of the illegal cannabis market in the United States. The study published in the International Journal of Drug Policy is one of the first studies to examine the impact of legalization on the illegal cannabis market using law enforcement cannabis seizure data. Currently, 40 U.S. states and Washington, D.C. have legal medical cannabis, and 24 states and D.C. have adult recreational cannabis laws. The study provides valuable insights into how cannabis legalization has affected the black market.
The researchers analyzed data from the High Intensity Drug Trafficking Areas Program (HIDTA). They focused on 286,844 cannabis seizures made by law enforcement agencies in all 50 states and Washington, DC between 2010 and 2023. The team linked this data with cannabis policy information from the RAND-USC Opioid Policy Tools and Information Center.
The findings indicated that states with legal recreational cannabis and medical cannabis experienced a 45% relative reduction in average cannabis seizure counts when compared with states with only legalized medical cannabis. The researchers noted this decrease both immediately after implementing recreational cannabis policy and one year later, when controlling for time trends and state demographic and law enforcement factors. Study author Dr. Nicole Fitzgerald explained that “The decrease in seizures may reflect a reduction in illegal cannabis supply, as consumers shift toward regulated markets and some illegal suppliers exit the market.” Additionally, changes in law enforcement priorities and practices may have contributed to this shift. Law enforcement agencies in jurisdictions with legal recreational cannabis may spend more time and resources focusing on the trafficking of other drugs, such as fentanyl and opioids.
Although legalization does not totally eradicate illegal markets in states with recreational legalization, state-regulated markets ensure access to safer, higher-quality cannabis products. More research is needed to determine the impact of cannabis policy implementation on the illegal cannabis market. Studies that focus on how cannabis law shapes law enforcement behaviors and drug enforcement priorities while considering the density of cannabis dispensaries will provide insights into specific ways that legalization decreases illegal markets. Studies should also highlight the specific conditions in each state with legal cannabis to determine how product price, access, and other factors of legal cannabis products affect the illegal market dynamics.
