As I closed my eyes and took a final lungful of air before the police academy instructor sprayed Red Sabre Max pepper spray directly into my face, I convinced myself it wouldn’t be so bad. After all, I’d had to endure the gas chamber every year while I was in the Marine Corps, and unlike CS gas, the pepper spray would be confined to just my face. Easy day, right? Several seconds passed after the nonlethal droplets showered my face, and the pepper spray felt no different than being misted with lavender Febreze. But when the instructor told me to open my eyes, things took an abrupt turn toward the horrible.

Immediately, it felt like a thousand needles had been jammed through my irises, fighting to burrow all the way to my brain. The pain got worse. Soon I found myself doubled over a garden hose, trying desperately to rid my face of the invisible fire. As I began to accept the fact that the pain wasn’t going anywhere anytime soon, I thought to myself, “This isn’t just worse than the gas chamber. It’s way fucking worse.”

The gas chamber is often the event recruits dread most going into military basic training. They’ve heard horror stories of choking on the putrid air and long ropes of snot stretching from their noses down to their boots, but there’s really no way to understand how it feels unless you’ve fought to breathe in that toxic air. Similarly, there’s really no way to fully grasp the pain caused by a direct blast of pepper spray until you’ve been lucky enough to experience it.

The chemical used to turn an empty gas chamber into a foggy nightmare is 2-chlorobenzalmalononitrile, or simply CS. First developed in the United States in 1928 by scientists Ben Corson and Roger Stoughton as a nonlethal alternative to some of the chemical weapons engineered during World War I, CS is now widely used to disperse crowds. The synthetic irritant reacts with moisture, causing a burning sensation in the eyes, coughing, excess mucus discharge, and difficulty breathing. It can even cause vomiting, dizziness, and disorientation. Brooks Bojanowski — a former US Army counterintelligence agent — described his first experience in the gas chamber like this:

“There was a strong burning in my eyes and snot just dumped out of my nose. It was really hard to breathe, but that was mostly from laughing at the idiots who tried to sprint out of the chamber as soon as their masks came off.”

Pepper spray, which gets its bite from oleoresin capsicum — an oil taken from the placenta of peppers — has similar effects. While it doesn’t directly affect breathing, it has a more immediate impact on the eyes.

“It feels like you’ve just had the world’s hottest pepper placed on your eyes,” Sgt. 1st Class Joseph Gonzales, former US Army nonlethal-weapons instructor, told Coffee or Die. “They instantly slam shut, tears start uncontrollably streaming, and snot pours out of your nose like a waterfall. No matter how badly you want to open your eyes, your body refuses, and they slam shut again.”

Tyler Newberry, a police officer with the Baltimore County Police Department, told Coffee or Die the feeling of getting pepper-sprayed reminded him of “face-planting on my boogie board as a kid. Like my eyes were violently stuffed with sand.”

With both the gas chamber and pepper spray, experiences vary. For me, there was a stark difference between going to the gas chamber the first time at boot camp and the subsequent annual certifications. At boot camp, sadistic Marine drill instructors poured a larger-than-normal pile of CS pellets on the small burner in the middle of the chamber and made the recruits do jumping jacks while singing the Marine Corps hymn, ensuring no one was holding his breath. They went even further, dishing out well-placed “corrections” to the short ribs of recruits still trying to avoid taking lungfuls of the noxious gas. All later trips to the gas chamber were far less uncomfortable. With no screaming drill instructors, one could simply break the mask’s seal and leave once the appropriate amount of time had passed. Still an unpleasant experience, but it was tolerable.

Getting pepper-sprayed has similar extremes. There’s certainly a difference between an instructor swiping the cone of spray across your face a few times and getting half of a can emptied directly into your eyes by a vengeful cop.

Both nonlethal weapons have proved very effective in using pain to make people comply, but let’s get down to what really matters: Is one actually worse than the other?

For Officer Gary Walsh, a Marine veteran and current police officer with the Springfield Township Police Department, the answer is a no-brainer.

“I would take the gas chamber over pepper spray any day, mostly because CS gas is the best decongestant money can buy," Walsh said. "But honestly, when you have to pepper-spray someone, you still have to go hands-on, so it ends up fucking you up too. Not to mention when you take a shower later, it will still be on you, and the water reactivates the spray, giving you a second dose. And for some reason, the gas chamber was always sort of fun because you went through it together.”

Newberry, whose department requires all police recruits to be exposed to both pepper spray and the gas chamber, agrees.

“Pepper spray is worse, for sure. You can’t see shit. You’re totally dependent on your friends to help you. There’s acute physical pain with pepper spray, whereas the gas chamber mostly just causes your eyes to water and your body to create a lot of snot. That’s more irritating than painful.”

Gonzales also concurs.

“Pepper spray is worse. The gas chamber has a bigger impact on your breathing, but within a minute of being out, you’re fine. Pepper spray lasts a while.”

Regardless of how rough the individual experience is, it’s pretty clear that, to those who’ve had the misfortune of experiencing the gas chamber and pepper spray, the latter is a much more painful encounter. But while one might suck a little more than the other, we highly recommend avoiding both.
