Even before the coronavirus pandemic, some experts said additional research was needed on the risks of tear gas — an umbrella term for several chemical "riot control agents" used by law enforcement. "This is a recipe for disaster," says associate professor Sven Eric Jordt, a researcher at Duke University School of Medicine who studies the effects of tear gas. CS gas is a chlorinated, organic chemical that can induce "very strong inflammation" and "chemical injury" by burning the skin and airways when inhaled, Jordt says.
