I'm taking this too seriously, but that's OK.

LSD isn't easy to make, but I'm assuming that on an industrial scale, it might be easier (and what a fun/terrifying factory to work in). Delivery is still a problem as is exposure of your own troops, at least initially. However, it does break down readily, so it wouldn't really destroy the landscape for eons. There's probably better and more easily manufactured chemicals that would have the same effect of making everyone go crazy, but it's still a nice concept...

You're still using the chemical as a weapon, so you're still violating treaties. Also, what exactly do you expect to accomplish with this? Wouldn't it depend a lot on the populace you were attacking? Certain groups might go nuts and begin killing one another, others might simply too frightened to go outside, and if you attacked, say, Santa Cruz, California, no one would notice anything was at all different from any other day...
