👉 A substance weapon is a type of chemical agent designed to incapacitate or harm individuals through exposure. These agents can be gases, liquids, or solids and are typically used in military or terrorist contexts to create fear, disrupt operations, or cause casualties. Substance weapons can affect the nervous system, respiratory system, or other bodily functions, leading to symptoms ranging from mild irritation to severe respiratory failure or death. Examples include nerve agents like sarin and VX, which inhibit acetylcholinesterase, enzymes critical for nerve signal transmission, while blister agents like sulfur mustard damage skin and mucous membranes. The development and use of these weapons are highly regulated due to their potential for widespread harm and the ethical concerns surrounding their deployment.
