Gas or drugs? Gas mask for junkies

Usually the so-called gas mask is used to prevent you from inhaling the gas, so as not to be poisoned to death, but this gas mask seems to let you inhale more gas ah! For the addict who loves to smoke, it is not enough to smoke, but also to suck up all the smoke, it is really "addiction", I did not expect the Japanese netshot actually appeared, this let you suck to explode gas mask!
