Blood agents are poisonous chemicals. They make it impossible for a person's blood to hold oxygen and bring it to the rest of the body. Every part of the body needs oxygen to survive. Blood agents can cause life-threatening symptoms like seizures or coma, which happen because the brain is not getting enough oxygen. In high enough doses, blood agents can make a person suffocate.
When they are used on purpose to kill many people, blood agents are weapons of mass destruction (WMDs).
The most common types of blood agents are chemical compounds that include cyanide. However, other blood agents are based on arsenic.
