I got CS gas (tear gas) in the military then OC spray (law enforcement grade pepper spray) in some training where we had to fight our instructor right after being sprayed. I'll take the CS any day. Hell, we used to go back into the gas chamber for fun after everyone went through. CS wears off in 10 minutes then you feel great, even better than before; it really clears you up. OC spray is like sunburn on your eyeballs for 8 hours.
People deserve what they tolerate.
