All my FAKs have OTC meds in them ...not because FIRST AID always involves dispensing pain meds ...but because my FAK is where I go to get Neosporin and a Band-aid for the cut on my hand when my folding shovels folds up on my hand when I didn't want it o....and when I get a headache.
I could carry all the OTC stuff somewhere else, but why not the FAK. One stop shop for big trauma and little alike.
I see no merit to narrowly focusing the use of my FAK.
Just my opinion.
