Devil's Pollen

Devil's Pollen is a hypothetical pollen grain produced by an unidentified plant (referred to as a berry bush for the purpose of thought experiment) that provokes a state of delirium in persons exposed to it, potentially causing them to self-harm or become otherwise injured or killed while in wilderness settings. The hypothesis is linked to the broader Missing 411.
