A former top War Department official warned that terrorists or rogue states could weaponize fentanyl into an aerosolized mass-casualty agent, citing a 2002 Russian hostage crisis where 130 civilians died after security forces used a fentanyl-based gas. David Lasseter, a former Deputy Assistant Secretary of Defense for Countering WMDs, praised President Donald Trump’s recent declaration of fentanyl as a weapon of mass destruction (WMD), calling it a critical step to combat both the cartel-driven opioid crisis and future chemical terror threats, Just the News reported.

WASHINGTON — The global proliferation of illicit fentanyl—fueled by drug cartels and black-market labs—has created a dual threat: a public health catastrophe killing hundreds of thousands of Americans and a looming terror risk where the same synthetic opioid could be weaponized into an aerosolized mass-killing agent, a former top War Department official warned.

David F. Lasseter, who served as Deputy Assistant Secretary of Defense for Countering Weapons of Mass Destruction, told Just the News that Trump’s recent executive action—declaring fentanyl a WMD—was a “bold and necessary move” to counter both the current opioid epidemic and the potential for fentanyl-based chemical warfare.

“This is a scourge on American society, but it also has really significant implications if weaponized,” Lasseter said. “The chemicals in illicit fentanyl and its precursors have already wreaked havoc on the health side. But there’s a real and growing concern about what could happen if it’s turned into a weapon.”

The 2002 Moscow Theater Siege: A Deadly Precedent

Lasseter pointed to a chilling historical example: the 2002 Moscow theater hostage crisis, where Russian security forces pumped a fentanyl-derived gas into a Chechen terrorist-occupied theater in an attempt to incapacitate the militants. The operation went catastrophically wrong—130 hostages died from overdoses of the poorly calibrated chemical agent, while the terrorists were killed.

“The Russians didn’t want to storm the theater against 40 heavily armed Chechen terrorists, so they used a fentanyl analog through the ventilation system,” Lasseter explained. “But the dose was too strong—it killed the terrorists, but it also killed 130 hostages.”

This tragic miscalculation, he warned, now serves as a “blueprint” for how fentanyl could be weaponized—especially as precursor chemicals become more accessible due to cartel mass production.

“If you think about this from a weaponization standpoint, an aerosolized form of fentanyl could be used to poison water supplies or food sources,” he said. “Given the proliferation of illicit materials, this is a very real and evolving threat.”

Fentanyl as a Chemical Weapon: A Warning Since 2019

The potential for fentanyl to be used as a WMD was flagged as early as 2019 in a National Defense University report. The study urged Western nations to amend the Chemical Weapons Convention (CWC) to explicitly ban fentanyl as a weapon—a recommendation that has yet to be adopted.

“It is clear that there is at least a risk that fentanyl compounds could be used as chemical weapons,” the report stated. “To mitigate that risk, the CWC should classify aerosolized fentanyl as a banned agent—just like nerve gas or mustard gas.”

Lasseter noted that while fentanyl isn’t yet listed in the CWC, international law already prohibits the use of any chemical designed to inflict mass casualties.

“Some might argue, ‘Oh, it’s not listed, so it’s not a violation,’” he said. “But the general purpose criterion of the CWC is clear: If a chemical is used as a weapon, it’s a violation—period.”

Trump’s WMD Declaration: A ‘Big Stand’ Against a Growing Threat

Trump’s December executive order—classifying fentanyl as a WMD—marks a major shift in how the U.S. will combat both the opioid crisis and potential terror threats.

“The President took a big stand here, and I think he made the right choice,” Lasseter said. “We used to hold up sugar packets in the Pentagon—five grams of fentanyl can kill hundreds of people if weaponized. Trump’s order highlights that reality—small amounts can kill individuals, but weaponized doses could cause mass casualties.”

The declaration empowers U.S. security agencies to:

  • Crack down harder on cartel fentanyl trafficking.
  • Develop countermeasures against aerosolized fentanyl attacks.
  • Push for international recognition of fentanyl as a chemical weapon threat.

A Race Against Time

With fentanyl flooding U.S. streets and terror groups constantly innovating, Lasseter warned that time is running out to prevent a catastrophe.

“The 2002 Moscow incident proved this can happen,” he said. “Now, with fentanyl precursors everywhere, the risk is higher than ever.”

Trump’s WMD designation, he argued, is a critical first step—but more must be done.

“We need global cooperation to treat fentanyl as the threat it is—both as a drug killing Americans and as a potential weapon of terror,” Lasseter said. “The President’s move puts the world on notice. Now, we have to act before it’s too late.”

Why It Matters:

  • Fentanyl is already killing over 100,000 Americans annually—weaponizing it could make it far deadlier.
  • Terror groups and rogue states have shown interest in chemical weapons—fentanyl is easier to obtain than traditional agents.
  • Trump’s WMD declaration gives the U.S. new tools to fight cartels and prepare for terror scenarios.

As 2026 begins, the fight against fentanyl is no longer just about public health—it’s about national security. And with Trump’s order, the U.S. is finally treating it that way.
