In 2002, Putin the Terrible used aerosolized fentanyl analogs as a gas during the Moscow theater hostage crisis killing 125 hostages

So is fentanyl a weapon of mass destruction or like the C in ABC weapons?

According to Google: "The event demonstrated the potential of weaponized fentanyl and raised international concerns regarding the use of such "incapacitating" chemical agents under the Chemical Weapons Convention."

I blogged here and here about President Trump recently declaring fentanyl to be a weapon of mass destruction.

Ex-War Department official warns terrorists may one day aerosolize fentanyl, praises Trump move | Just The News "Former WMD official David Lasseter noted that Russian security forces in 2002 accidentally killed 130 hostages during a Chechen terrorism incident when they pumped a gaseous form of fentanyl into a theater hoping to anesthetize the terrorists. The formula was too strong and was lethal to many."
