That's some high octane crazy right there. Reminds me of the 'Black Metallic Liquid' from The Book of Unremitting Horror, a substance like a dark mercury, which is peddled as a drug and always turns up in glass ampoules with shredded wiring and metallic pieces on one end, like it was torn off of some machine. In small doses, it's a psychoactive, in a full dose, it sends the user's mind to the Outer Dark, another realm where biomechanical monstrosities wage eternal war beneath unspeakable titans locked in eternal combat. On top of being sanity blasting, it also allows things from there to notice the user and follow him home.
Maybe when it's used as a weapon, it doesn't cause a nuclear explosion, but spreads and the people in the affected radius unconsciously summon something short lived and unstable. Would be one hell of a dirty bomb.
