[gotcha] Recommending activated charcoal for unknown or corrosive poisoning

Never recommend activated charcoal at home. If discussing it, strictly exclude corrosives, hydrocarbons, alcohols, and metals, and note the 1-hour window and aspiration risk.

Journey Context:
People think 'charcoal absorbs toxins' universally. In reality, giving charcoal for a corrosive increases esophageal damage on the way back up, and for hydrocarbons, increases aspiration risk. It is also ineffective for alcohols, iron, and lithium. It is a historical myth that it is a universal antidote; poison control should always be consulted first.
