What is the most deadly poison?
A well-known toxin, Cyanide is a deadly poison that affects the central nervous system (CNS) as well as the heart. Even if a small dose of cyanide enters the body, the poison will attack the blood stream and bind to the iron in the blood, thus prohibiting oxygen to flow through the body, resulting in death in minutes. Though there are different forms of Cyanide , Hydrogen Cyanide, is by far the deadliest of them. Considered a chemical weapon as a gas, Hydrogen Cyanide is incredibly deadly, killing a human in less than ten minutes. In fact, the poison was used as such to devastating effect during the First World War, before chemical weapons were banned under the Geneva Convention.
