US President Donald Trump signed an executive order on Monday declaring fentanyl a “weapon of mass destruction” and classifying the synthetic opioid as both a deadly narcotic and a potential chemical weapon under US law.
In a White House press release accompanying the order, the president emphasized the drug’s deadly effect and the scale of the public health crisis it has caused. “Illegal fentanyl is closer to a chemical weapon than a narcotic. Two milligrams, an almost undetectable trace amount equivalent to 10 to 15 grains of table salt, is a lethal dose. Hundreds of thousands of Americans have died from fentanyl overdoses,” the statement said.

The executive order itself adopts broad language. “As President of the United States, my highest duty is to defend the country and its citizens. Accordingly, I hereby designate illegal fentanyl and its basic precursor chemicals as weapons of mass destruction (WMD).”

How will the US government respond?
The directive directs both the Pentagon and the Justice Department to take further steps to disrupt the production and distribution of fentanyl, signaling a broader use of national security tools in what has traditionally been seen as a criminal matter and a public health issue.
According to the White House, the designation “unlocks all tools to fight the cartels and foreign networks responsible for flooding communities with this deadly substance.” It also warns that fentanyl could be used as a weapon for “concentrated, large-scale terrorist attacks by organized adversaries.”
What are the legal implications?
It remains unclear what immediate changes the designation will bring. Under current US law, it is already a crime to threaten or attempt to use weapons of mass destruction. The Department of Homeland Security has historically defined such weapons as “radiological, chemical, biological, or other devices intended to harm large numbers of people.”

Legal analysts note that while the designation carries strong symbolic weight, its practical effect will depend on how aggressively federal agencies reevaluate existing laws and authorities.
Do the US administration’s claims convince experts?
The Trump administration’s claim that fentanyl could be used in “concentrated, large-scale terrorist attacks by organized adversaries” has been met with skepticism among drug policy and security experts.

Jonathan Caulkins, a professor at Carnegie Mellon University who studies drugs, crime, terrorism and violence, disputed that premise, telling Stat News, “Neither terrorist organizations nor militaries use fentanyl as a weapon. It’s not clear to me that it’s a threat.”
How does this fit into Donald Trump’s broader drug strategy?
Trump’s executive order follows a series of tough moves by the US administration. Earlier this year, the US government designated major drug cartels as foreign terrorist organizations, a move widely seen as laying the groundwork for military action against them.
Since early September, the administration has conducted more than 20 strikes against suspected drug vessels in the Caribbean and Pacific, operations that have reportedly killed more than 80 people.

But military experts say cartels operating sea routes in the Caribbean are typically associated with cocaine trafficking, while fentanyl is mostly routed to Europe, not the United States. Little public evidence has been presented to show that the targeted vessels were carrying drugs.
Still, Trump has repeatedly threatened strikes on the ground in Venezuela, Colombia and Mexico as part of his anti-drug campaign. In a wide-ranging foreign policy strategy document released last week, he said his administration would focus on reasserting American dominance in the Western Hemisphere.
What role do Mexico and China play?
Mexico remains the largest source of illicit fentanyl entering the United States, while many of the chemical precursors used in its production come from China. Although fentanyl remains the leading cause of overdose death in the US, the death rate associated with the drug has begun to decline in recent years.

Despite this trend, Trump continues to cite fentanyl as a central national threat, using it to justify tougher criminal penalties, aggressive trade policies and stricter immigration enforcement. The administration has also repeatedly — and falsely — accused undocumented migrants of fentanyl trafficking.
What do public health experts say?
Public health experts have warned that the administration’s strategy risks overlooking the domestic addiction crisis that is driving demand for fentanyl. Critics say cuts in staff and resources to federal agencies responsible for addiction treatment and drug policy have weakened the national response.
The administration has also moved to withhold funding from some harm-reduction organizations, while proposed cuts to Medicaid — the program that provides health care to low-income Americans — have raised alarm among doctors and advocates. Law enforcement and public health experts have warned that such a reduction could seriously undermine efforts to treat substance use disorders.
