Why we checked itSpecific statistic about the proportion of fentanyl entering the US through legal border checkpoints — a frequently cited but contested figure in immigration and drug policy debates
What we foundCBP data and analyses by the Cato Institute, the American Immigration Council and GAO find that most seized fentanyl, about 84 to 93 percent depending on the year, is caught at official ports of entry, with about 90 percent in fiscal 2023. The figures describe seizures, the measure these sources use.
CorrectedCorrection: Originally rated Overstated. Rating changed to Supported following post-debate review: CBP data put the share of seized fentanyl caught at ports of entry at about 84 to 93 percent depending on the year, close to 90 percent in fiscal 2023, so the figure is within the range the evidence reports. The evidence is unchanged; the summary was rewritten to match.
