Entire Body System
- Inflammation
The effects of these agents are typically limited to minor and transient cutaneous inflammation, but serious complications and even deaths have been reported. [bmj.com]
Pepper spray is an inflammatory agent that causes inflammation in the eyes, nose and mouth. Its effect is more debilitating, but you have to hit someone with it directly for it to be effective. [says.com]
It may cause chemical pneumonitis (inflammation of lung tissue.) In some cases it can give you a pulmonary edema — a sudden build up of fluids in the lungs. That’s a proper medical emergency, but it’s very rare. [caracaschronicles.com]

- Swelling
Eyes water and eyelids swell up. When a person inhales it, the body produces mucus. "That's why many people feel tear gas can be suffocating," Jordt said. "It produces a drowning feeling that your airways are filled up with liquid." [usatoday.com]
Capsaicins inflame the airways, causing swelling and restriction. And this means that pepper sprays pose a genuine risk to people with asthma and other respiratory conditions. [ww2.kqed.org]
Pepper spray causes painful swelling of capillaries in the eyes and caused temporary blindness. Pepper spray is relatively simple compared to CN and CS gases. As the name would suggest, it is derived from peppers. [bcachemistry.wordpress.com]
If the patients are injured in other ways, doctors run into trouble when performing surgery — the swelling in the throat can make it impossible to intubate them, so they can't breathe if they need to be sedated. [businessinsider.com]
