Poison gas is really not a very good weapon of warfare, because although it can be very deadly, it is not very accurate; it goes wherever the wind blows it. So the gas you use might poison enemy troops, or it might poison your own troops. Poison Gas was outlawed by the Geneva Convention after WWI, thou it was still used in small amounts during WWII. This use did not include the massive use of poison gas to kill the Handicapped and then the Jewish people in WWII by the Nazi's (German's)
