Trump Designates Illicit Fentanyl as a Weapon of Mass Destruction in Executive Order
WASHINGTON, D.C. — President Donald Trump signed an executive order on Monday formally classifying illicit fentanyl as a “weapon of mass destruction,” a move intended to bolster the federal government’s arsenal in combating the opioid crisis. The order, announced in the Oval Office, highlights fentanyl’s potential to be weaponized for large-scale terror attacks, marking a significant shift in how the substance is legally and strategically addressed.
“Illicit fentanyl is closer to a chemical weapon than a narcotic,” the executive order states, emphasizing that as little as two milligrams—a trace amount comparable to 10 to 15 grains of table salt—can be lethal. This potency, combined with fentanyl’s relatively low manufacturing cost, has led traffickers to lace it with other drugs or counterfeit prescription pills, including oxycodone and alprazolam, to increase potency and profits.
The designation aims to unleash “every tool to combat the cartels and foreign networks responsible for flooding communities with this deadly substance,” according to the order. It directs the Department of Defense to enforce criminal codes related to fentanyl and tasks the Justice Department with pursuing harsher penalties for fentanyl-related crimes. Additionally, the Treasury Department is instructed to take action against assets and financial institutions linked to fentanyl manufacturing and distribution, while the Department of Homeland Security is charged with identifying threat networks using weapons of mass destruction intelligence to support counter-fentanyl operations.
At the signing event, President Trump underscored the gravity of the crisis, stating, “No bomb does what this has done. 200,000 to 300,000 people die every year, that we know of. So we’re formally classifying fentanyl as a weapon of mass destruction.” He also honored U.S. service members with medals for their role in border protection, reviving the “Mexican Border Service” medals originally established by Congress in 1918.
Fentanyl has been the leading cause of death among Americans aged 18 to 45, with the Centers for Disease Control and Prevention reporting an estimated 80,391 overdose deaths in 2024, more than half involving synthetic opioids like fentanyl. Despite a 37% decline in synthetic opioid deaths between 2023 and 2024, experts caution that supply-side efforts alone have not sufficed to curb the epidemic.
Dr. Daniel Ciccarone, a University of California researcher specializing in illicit drug trends, noted in May that harm reduction strategies remain critical to keeping users engaged and reducing fatalities, warning that reliance on supply shocks is not a sustainable solution.
While the executive order targets illicit fentanyl, it does not affect the legal medical use of fentanyl, which remains available in various forms such as patches, lozenges, and injections for pain management and anesthesia.
Most illicit fentanyl entering the United States is manufactured in Mexico with precursor chemicals imported primarily from China and India. The Pentagon has intensified efforts to intercept drug shipments, conducting airstrikes on vessels in the Caribbean and eastern Pacific to disrupt trafficking routes.
The FBI defines a weapon of mass destruction as a device or substance designed to cause death or serious injury through chemical, biological, or radiological means. By classifying fentanyl under this category, the administration seeks to expand legal tools and resources to dismantle the networks responsible for its distribution.
Some legal experts, however, have expressed skepticism about the practical impact of the designation. Dennis Fitzpatrick, a former national security prosecutor, described the move as a “political exercise,” noting that existing statutes already provide robust mechanisms to prosecute fentanyl-related crimes.
In July, President Trump signed bipartisan legislation reclassifying fentanyl as a Schedule 1 drug under the Controlled Substances Act, imposing mandatory minimum sentences for trafficking quantities exceeding 100 grams. The new executive order complements these efforts by framing fentanyl as not only a public health crisis but a national security threat.
As the opioid epidemic continues to claim hundreds of thousands of lives annually, the administration’s latest action signals an intensified federal commitment to combating the scourge of synthetic opioids through enhanced legal and operational measures.
