Information about grenade and chemical cartridges

Does any of you guys can help with some details about the grenade cartridges and the chemical (poisoned) cartridges used in the past? They aren’t that well known thus little information can be found on the Internet. Thanks to anyone who will take his time to help me.

I believe most any & all of that sort or information is most likely highly classified.

Unless your talking decades or more ago? The only thing that comes to my mind (small arms, I know nothing about larger items) is the 9mm Luger that was thought to have Cyanide in it? But as far as I’m aware none have been proven to lbe loaded as such. Lew can likely comment more on this.
