Smoke grenades are illegal in many states, including the one I live in; Cali. Make sure you are not breaking any fire regulation laws before you use them.

In Commiefornia they ban almost everything that is fun.....

Don't the homemade ones produce toxic smoke?

Also, alot of fields won't allow you to use ''hot'' smoke. They prefer grenades with an internal fused started by pullrigng. Check the the head guy of your field to make sure your pyro is ok.
