Pyrotechnic pepper spray

Summary
How to make pyrotechnican pepper spray?
Hello. Ordinary pepper sprays on the market are cans pressurized with propane, butane etc., that propells the liquid pepper through a spray nozzle.

So I thought, would it be possible to make a pyrotechnic composition that act as pepper spray? Either that the burning powder itself act as a strong (but non-lethal) irritant, or through using carolina reaper chili powder or pure capsaicin mixed together with a burning powder that propells it?

If you load a cannon or a shotgun round with capsaicin/pepper-powder instead of lead, and simple shoot it out from the barrel, you will get a pepper shot, but I want to achieve a steady stream/spray pattern that keep going for a while, like a rocket engine, or a pressurized can.

Any ideas on how to achieve this? I guess there’s a bunch of different solutions that could work.
