WWII Reanctor/Architecture Student
Alright, so the militia a friend and I started up (we've checked our rights and law systems, and all of us are 16+), and we have come accross a still sterile first aid kit from '42! Pretty much complete contents, except for the first aid cream and Spirit of Ammonia. Now, we handed it to our field medic, and he noticed it still had the box of 3 ammonia inhalants. We all know what these are used for. Basically I want to know if they're still usable, or should be chucked.
