BLOOD AGENTS
Blood agents are typically made of either cyanide or arsenic. Let’s just say you don’t want to accidentally put either of those in your coffee; both agents are banned by international law.
As weapons, they’re usually administered in an aerosol spray. And the more you inhale, the worse off you are. A very small amount probably won’t do much permanent damage, but will probably cause headache, nausea, or dizziness. (Case in point? Cigarette smoke contains cyanide.) Exposure to greater amounts over more prolonged periods of time can lead to convulsions and comas. Too much exposure will kill you.
