// The area-reaction effect canceling is part of avoiding smoke-fork-bombs (create two smoke bombs, that when
// ingested by mobs create more smoke). This also used to act as a rapid chemical-purge, because all the
// reagents would get carried away by the smoke/foam. This does still work for the stomach (I guess people vomit
// up the smoke or spawned entities?).
// TODO apply organ damage instead of just blocking the reaction?
// Having cheese-clots form in your veins can't be good for you.
