Ammonium nitrate is already controlled in several parts of the world

ANFO is explosives made with ammonium nitrate(Ammonium Nitrate Fuel Oil), however ammonium nitrate is by itself rather energetic and will explode when store improperly. The most recent memorable incident would be 2020 Beirut: https://en.wikipedia.org/wiki/2020_Beirut_explosion

Imagine one of these units left somewhere, slowly filling a tank that has not been sealed, water evaporating back out leaving a nice ammonium nitrate powder behind....

There's a ton of water in the air for it to react with
