There are many chemical weapons in existence. One of these is Sarin Gas. Sarin is one of the deadliest chemical warfare agents. It disrupts the nervous system, overstimulating the vital organs and muscles. The lethal dose is about one drop.
VX gas is another one of the most feared chemical agents. It has never been used to it's fullest potential for fear that wind currents will blow the chemical back to where it came from. One milligram is enough to kill a person.
Mustard gas has been around since world war 1. It blisters the skin and burns the lungs. About 10 milligrams in the lungs can kill a person.
Cyanide is usually found joined to other chemicals to create a chemical compound. Some examples of these compounds are hydrogen cyanide, sodium cyanide, and potassium cyanide. Hydrogen is a colorless gas with a bitter, almond like smell. Cyanide ingestion can result in pains, brain and heart problems, coma, and death.
