This is quite obviously not a “real” syndrome caused by foreign adversaries. The physics, scale of “attack”, timeline, vagueness of symptoms, etc, all do not add up to a coherent phenomenon. Please put your skeptic hats on regarding this subject.
My friend described the original symptom cluster as "Havana few too many syndrome" (as in a few too many drinks), which I think is probably about right. From there it's just people working themselves into a panic over nothing, like american cops with fentanyl "exposure": https://www.npr.org/2023/05/16/1175726650/fentanyl-police-ov...
