More than 1.1 million people in the United States have died from opioid overdoses since 2000. In Canada, over 50,000 lives have been lost to opioid-related overdoses since 2016. Meanwhile, in Mexico, homicide—mostly committed with illegally trafficked firearms—is the leading cause of death among men aged 15 to 44. These overlapping crises reveal that the harms associated with synthetic opioids are not confined to one country but span all of North America.

This policy brief sheds light on how illicitly manufactured fentanyl (IMF) is produced and distributed within and across Mexico, the US, and Canada. The report reveals a complex and highly integrated system of production, tablet pressing, trafficking, and consumption. Far from being a product trafficked into North America, IMF is increasingly produced on its soil.

Key insights include the emergence of a new “golden triangle” of trafficking and violence between the Mexican states of Baja California, Sonora, and Sinaloa, where fentanyl production overlaps with high levels of firearm-related homicides. Fentanyl production in Mexico is closely linked to firearms trafficking from the United States, with Arizona emerging as a predominant source. In Canada, production largely serves the domestic market using chemical precursors imported directly and processed in clandestine labs. In the US, criminal actors engage in adulteration and tablet pressing—often making use of legal trade flows and customs loopholes to facilitate trafficking.

The paper also challenges common assumptions: 83.5% of those convicted of fentanyl trafficking in the US in 2024 were US citizens, and most trafficking across the Mexico–US border occurs through legal ports of entry, not between them.

Recommendations for all three countries focus on data transparency, coordinated public health responses, and transnational cooperation. The paper calls for more investment in evidence-based interventions and a shift away from unilateral or enforcement-only strategies.

Deaths in North America from overdoses and homicides linked to fentanyl are not inevitable. But addressing it requires governments to exchange know-how and coordinate action across borders, just as criminal networks do.
