What is lewisites?

Lewisite is a chemical warfare agent that was developed in 1918 by American chemist, Winford Lee Lewis. It is a blister agent that can cause severe burns and blistering of the skin, eyes, and respiratory system. It is a clear, colorless, oily liquid with a strong garlic-like odor.

Lewisite was used during World War I by the US Army and was later stockpiled by several countries including the Soviet Union, Iraq, and Iran. It has since been banned and declared an illegal weapon of war under the Chemical Weapons Convention of 1993.

Exposure to Lewisite can lead to a range of acute symptoms including coughing, choking, eye and skin irritation, and blisters or burns on the skin. Prolonged and high-level exposure can cause severe long-term health effects such as cancer, blindness, and respiratory problems.

There is no antidote for Lewisite exposure. Treatment involves removal of clothing and decontamination with water and soap. Medical treatment involves supportive care such as oxygen therapy and pain management.

Lewisite is considered a highly toxic and dangerous substance. Its production and use are strictly regulated by international law.
