Cholinergic agents include which category that can be weaponized?

• A. Chloroform
• B. Nicotine
• C. Organophosphates
• D. Ethanol

Answer: (C)

Cholinergic agents that can be weaponized are those that cause excessive acetylcholine activity by blocking its breakdown. Organophosphates inhibit acetylcholinesterase, the enzyme that normally degrades acetylcholine. When this enzyme is blocked, acetylcholine builds up at both muscarinic and nicotinic receptors, leading to widespread overstimulation. This can produce a dangerous cholinergic crisis marked by increased secretions, sweating, bronchorrhea, pinpoint pupils, bradycardia, muscle fasciculations and weakness, and potentially respiratory failure. Because of their strong, broad effects and potential for harm, organophosphates have historical and ongoing relevance as a weaponizable cholinergic agent. Chloroform and ethanol are primarily CNS depressants, not cholinesterase inhibitors, so they don’t fit the category. Nicotine is a cholinergic agonist at nicotinic receptors but does not inhibit acetylcholinesterase, so it’s not the representative weaponizable cholinergic category here.
