Ammonium carbonate is mixed with perfume to create a stimulant. The ammonia fumes from the salts irritate the membranes of the nose and lungs, which triggers a reflex causing the muscles that control breathing to work faster. (This is how they relate to Weightlifting and Powerlifting HEAVY reps and sets!!) They are used to revive athletes when they have passed out during sports or to revive individuals who have fainted.

You just sniff before you are about to max on lifts for that extra kick in the ass wake up lol
