President Trump claimed a 56% reduction in fentanyl trafficking during his February 2026 State of the Union address, but the verified data does not support that figure. U.S.
Customs and Border Protection's actual documented seizures fell 46% from fiscal year 2024 to 2025—a decline of approximately 9,600 pounds—but experts caution that seizure numbers capture only detected drugs and cannot measure the total amount of fentanyl actually entering the United States. The discrepancy between Trump's public claim and CBP's data highlights a broader measurement problem: politicians often cite seizure statistics as proof of enforcement success, but researchers note these numbers reflect only what agents caught, not what got through. Understanding what the data actually shows—and what it cannot—is essential for readers evaluating border enforcement claims.

What CBP's Data Actually Shows
CBP documented 11,486 pounds of fentanyl seized in fiscal 2025, down from approximately 21,148 pounds in 2024—a 46% reduction, not the 56% trump claimed. This was the lowest seizure total since 2021. However, Trump made conflicting claims within days, first citing a 30% reduction tied to tariffs, then stating 56% in his formal address, raising questions about the basis for either figure.
The reduction occurred across the southern border, but it was heavily concentrated: 86% of CBP's 2025 fentanyl seizures happened at official ports of entry, not between ports or in remote areas. Additionally, 96% of all seizures were concentrated in California and Arizona, meaning most other border states saw minimal activity or reporting. This geographic concentration matters because it shapes which enforcement strategies appear to work.
Why Seizure Numbers Do Not Measure Actual Fentanyl Flow
A critical limitation: seizure data cannot answer the question "How much fentanyl is actually entering the U.S.?" Seizure statistics only capture drugs that agents detected and do not account for undetected amounts, according to a drug policy fellow quoted by FactCheck.org. If enforcement methods improved and caught more of what was coming through, seizures could rise.
If cartel production fell, smuggling routes changed, or more fentanyl went undetected, seizures could fall for reasons unrelated to actual drug flow. The 2026 data complicates the picture further. Fentanyl seizures between January and July 2026 were only 2% higher than the same period in 2025, suggesting the sharp 2025 decline did not continue as a sustained trend. Without knowing what drove the 2024–2025 drop or why 2026 leveled off, policy makers cannot confidently attribute changes to any single enforcement action.
Who Actually Smuggles Fentanyl Into the U.S.
Border enforcement often focuses on immigrants and asylum seekers, but the data show a different pattern. U.S. Citizens—not migrants—smuggle the majority of fentanyl into the United States, according to CBP arrest data, though much of the drug originates in Mexico.
This means enforcement targeted at border crossings and asylum pathways may not address the primary smuggling mechanism. The fact that citizens handle most fentanyl smuggling also suggests that seizure reductions at the southern border may reflect changes in trafficking routes (such as tunnels, mail, or ports) rather than changes in how much fentanyl enters. For readers evaluating immigration enforcement policy, this distinction matters: does border enforcement address the actual flow, or does it target visible entry points while smuggling adapts elsewhere?
Possible Explanations for the 2024–2025 Decline
Experts have identified several possible reasons for the fentanyl seizure drop, but no consensus explanation exists. The decline could reflect reduced cartel production, Mexican government enforcement, new scanning technology at ports of entry, reduced U.S. demand, or undetected smuggling methods such as tunnels. None of these can be ruled in or out based on seizure data alone.
If the decline resulted from Mexican enforcement or reduced cartel supply, it represents international and criminal-market forces, not U.S. border policy. If it reflects new scanning technology or routes through official ports, it may reveal enforcement adaptation. Without evidence pinpointing a cause, crediting the decline to any single policy—tariffs, staffing, technology, or otherwise—remains speculative.
What This Means for Border Policy and Readers
For readers evaluating immigration and border enforcement claims, the gap between Trump's 56% claim and CBP's 46% documented data illustrates a common pattern: politicians cite selective statistics, and the underlying details often tell a different story. The actual 46% reduction in seizures is significant, but it captures only detected drugs at mostly official ports of entry where enforcement is visible.
The concentration of seizures in two states, the primary role of U.S. citizen smugglers, and the reversal in 2026 trend suggest that border enforcement alone does not control fentanyl flow. Immigration policy changes may affect visible border crossings without addressing the broader mechanisms that move drugs into the U.S. Readers assessing claims about border security and drug trafficking should ask: What was actually measured? What is not captured in that number? And what changed to cause the shift?

Frequently Asked Questions
Is the 56% reduction real?
The actual CBP-documented reduction is 46%, not 56%. Trump made conflicting claims within days—citing 30% tied to tariffs, then 56% in his State of the Union—raising questions about the basis for either figure.
Does a drop in seizures mean less fentanyl is coming in?
Not necessarily. Seizure numbers reflect only detected drugs and cannot measure undetected amounts. The decline could result from reduced production, cartel route changes, improved U.S. scanning, or fentanyl moving through undetected smuggling methods such as tunnels.
Who smuggles most fentanyl across the border?
U.S. Citizens smuggle the majority of fentanyl, though much of the drug originates in Mexico. This means enforcement focused on border crossings may not address the primary smuggling mechanism.
Where do most fentanyl seizures happen?
86% occur at official ports of entry, and 96% are concentrated in California and Arizona, meaning most border states see minimal activity or reporting.
