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.

The NFL is banning the use of smelling salts and ammonia packets before and during all games, a ruling that has upset 49ers TE George Kittle.

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