After loud backlash from players, the NFL players’ association clarified in its own memo that the league hasn’t banned the use of smelling salts — it has only banned teams from being the suppliers. What does that mean for players? They can still use ammonia inhalants, as long as they bring their own.

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.
