What is the impact of chemical warfare on civilian populations?

### REPLY:
Chemical warfare involves the deliberate use of toxic substances, such as nerve agents and blister agents, to harm or kill people. These weapons can cause excruciating pain, respiratory distress, and organ failure. The impact on civilian populations is catastrophic, with widespread death and suffering. The use of chemical weapons is prohibited under the Chemical Weapons Convention, but some countries continue to possess and use them secretly.
