Ammonia and smelling salts have long been used by NFL players before and during games to give them an extra pick-me-up whenever they need a boost of energy. This includes any form of smelling salts and ammonia capsules or inhalers.

Ever seen smelling salts used on the air? Well, the cast of "First Things First" did so on Thursday, and George Kittle approves.

49ers Star George Kittle Is Not Happy with NFL Over New Rule originally appeared on Athlon Sports. On Tuesday, the NFL issued a memo to all 32 clubs announcing a ban on ammonia inhalants, commonly known as smelling salts, effective for the 2025 season.
