One is whether or not the epinephrine can be legally carried in the medical
kit of a certificated airliner. It can be, and is.

It is legal to carry and possess prescription drugs in certain contexts, but
that is distinct from the authority to dispense or administer them.

Two is the process under which the epinephrine gets used. There are a
variety of personnel authorized to administer regulated drugs without
having a prescription. Physicians are certainly on that list.

Where can I find this list?
