I see it as a real and dangerous problem that people think they can short cut their physical preparation and acclimation knowing performance enhancing drugs might get them by without putting the actual study,and preparation necessary.
That is not the use of dex suggested here.
and
all of the study, preparation and acclimatization in the world will not prevent all cases of AMS and its complications. As an example, after his success on Everest in 1953, Ed Hillary later went to Makalu and developed HAPE. If it can happen to Sir Ed, it can happen to me and you.
