👉 Chemical weapons are toxic substances used as weapons of mass destruction, designed to incapacitate or kill by damaging the nervous system, respiratory tract, or skin. They can be classified into several categories, including choking agents (like chlorine and phosgene), blister agents (such as sulfur mustard), and nerve agents (like sarin and VX). These chemicals are often deployed in gaseous, liquid, or solid forms and can cause severe health effects, including immediate death or long-term disabilities, due to their potent toxicity and ability to spread rapidly.
