No, but they might not travel with a pharmacy, they might not arrive right away, I might have inhaled smoke prior to their arrival or during the emergency exit. Based on your experience with asthma, smoke inhalation, asthma attacks, first responders etc. which must be vast, would you risk the life of yourself or toddler on the off chance the first firefighter you see has an inhaler in his pocket?

If it meant the difference between me possibly not getting off the burning plane, yes I would. You don't need to have experience with asthma to know that getting off of a burning plane is better than dying and getting other innocent people killed while reaching for a bag.
