Poison Gas and World War Two. The use of poison gas in World War Two was a very real fear. Poison gas had been used in World War One and many expected that it would be used in World War Two. As a result people in Britain were issued with gas masks and gas mask drills became a routine. The gases used in World War 1 were crude but effective. In fact, technically many of them were not gases but minute solid particles suspended in air like the spray from an aerosol can. Regardless of whether they were a true gas or not, they brought very great fear to the front line.
