There is no conflict. These are tools to be used in an contingency, like how car insurance or airbags, or a PLB is used in an emergency.
That is different from using these drugs as part of a plan when no emergency has occurred, ie, climb 4 pitches, take two doses of stimulants, climb 3 more pitches, take more stimulants, etc. You can still be on a hazardous trip where no emergency has occurred.
