In Tijuana, fentanyl is no longer just a story about trafficking. It represents a binational public health breakdown, where overdose deaths in the U.S., Mexican border poverty, deportation, cheap access, and daily cross-border movement have turned addiction into a shared wound.
The Border Crisis Goes Both Ways
For years, the dominant narrative has flowed in only one direction: drugs cross northward, death follows in the United States, and Mexico remains pigeonholed as the supplier of poison. But in Tijuana, the border reveals a more uncomfortable truth. The crisis is also moving southward. People cross over carrying hunger, dependency, deportation papers, U.S. benefit cards, trauma, and the unbearable arithmetic of cheaper survival.
The trafficking and consumption of fentanyl along Mexico’s northern border have created a binational emergency—one that reveals not only the flow of drugs into the United States but also the displacement of U.S. drug users into cities like Tijuana. According to interviews cited by EFE, the reasons are brutally practical: lower costs, easier access to substances, cheaper food, cheaper housing, and a border that many people cross so frequently that it ceases to be a mere line and becomes a daily routine.
Alfonso Chávez, coordinator of the Prevencasa A.C. program, told EFE that the northern border concentrates specific problems regarding injectable drug and opioid use that are distinct from Mexico’s national landscape. National surveys identify methamphetamine as the primary substance consumed throughout the country. But Tijuana belongs to a different system. Its drug crisis is shaped by U.S. demand for opioids, deportation, homelessness, immigration enforcement policies, daily border crossings, and the economic disparity between San Diego and northern Mexico.
That distinction matters because national policy is bound to fail if it proceeds under the assumption that the border is just another ordinary region. Chávez warned that centralizing public policy—rather than designing differentiated strategies for northern Mexico—amounts to downplaying a phenomenon with its own distinct characteristics. In other words, a plan designed for the entire country may arrive too late, prove too generic, and remain too blind to the specific geography where fentanyl, migration, and poverty intersect.
The United States records more than 70,000 opioid-related deaths annually, Chávez noted—a figure that helps explain the gravity of the problem in a region where people constantly cross back and forth between the two countries. This death toll is often treated as a uniquely American tragedy. And it is. But Tijuana demonstrates that the tragedy does not stop at the border fence. It spills over into Mexican clinics, shelters, streets, emergency services, and neighborhoods that were already burdened by the weight of deportation, violence, precarious labor, and urban neglect.
The Economy of Cheap Survival in Tijuana
Staff members at Prevencasa have treated several individuals who overdosed shortly after crossing over from the United States, Chávez said. Among them are deportees as well as U.S. citizens who travel regularly between cities such as San Diego and Tijuana. Some do not live permanently on the streets; rather, they move back and forth, navigating life in both cities on a daily basis.
This detail shatters the stereotype. It is not merely a story of abandoned individuals sleeping under bridges—though many certainly do. It is also a story of cross-border mobility, economic inequality, and a mode of survival that is simultaneously legal, illegal, medical, informal, and desperate. A person might wake up in Tijuana, cross into the United States to maintain their enrollment in social assistance programs, return south, and spend the money in an economy where illicit substances are cheaper and the overall cost of living is lower.
Mike, a California native, told EFE that the high cost of living in the United States has driven many Americans to settle temporarily in Tijuana. He stated that he crosses into the U.S. daily to register for and maintain government financial assistance, using those resources to sustain his stay in Mexico and cover expenses related to drug use.
This is the hidden side of North American integration. Goods, workers, tourists, money, weapons, and drugs cross the border. So do diseases. So do addictions. As do the failures of housing policy, access to healthcare, and social protection. The border economy does not merely connect two nations; it exposes the inequality between them.
