My father always said it was like coliodial silver & that had always been good for the body.

So the real question I have is, is silver iodide harmful to humans? Also, does anything else get sprayed in the air under the assumption it is just silver iodide?

Cloud seeding has been a thing for decades & because it was essentially coliodial silver I never questioned it & was greatful it helped farmers get more rain for the crops in our desert environments.
