As long as low grade firecrackers are used in this, I feel it acceptable for use.
We've got a couple guys here that use a Tennis ball. cut it open-insert some peas (Because peas are cheaper and a little softer) then insert the explosive device from a firework fill with more peas and let the tennis ball close itself. They usually put in an 8 sec fuse which, if you know how to find the burn rate of the fuse, can make your grenades rather effective. Throw immediately after lighting for longer ranges or bake it a few seconds for short throws.
but, to be on the safe side, all players should be aware of your grenades and know that it goes "BAANG!!" so diving out of the way instead of trying to return would have it's incentive.
