My own purpose here is to focus on the dangers of a high level of capsaicin exposure. But as pointed out in the 2004 paper, Health Hazards of Pepper Spray, written by health researchers at the University of North Carolina and Duke University, the sprays contain other risky materials:
Depending on brand, an OC spray may contain water, alcohols, or organic solvents as liquid carriers; and nitrogen, carbon dioxide, or halogenated hydrocarbons (such as Freon, tetrachloroethylene, and methylene chloride) as propellants to discharge the canister contents.(3) Inhalation of high doses of some of these chemicals can produce adverse cardiac, respiratory, and neurologic effects, including arrhythmias and sudden death.

Pepper spray use has been suspected of contributing to a number of deaths that occurred in police custody. In mid-1990s, the U.S. Department of Justice cited nearly 70 fatalities linked to pepper-spray use, following on a 1995 report compiled by the American Civil Liberties Union of California. The ACLU report cited 26 suspicious deaths; it’s important to note that most involved pre-existing conditions such as asthma. But it’s also important to note a troubling pattern.
