Narcan (Naloxone) Training
Administering too much too quickly and completely killing their high. As others have stated, titrate to respiration’s. If some rescue Ricky doo gooder shows up on scene to be a hero and kills some junkies high, now have someone who’s really pissed off and possibly a seizure patient. So what now? Is average joe prepared to deal with a combative junky or a seizure?
ETA: How long before some over zealous wanna be medic ends up burning down a junky after he administers narcan, kills the dudes high and he becomes combatant?
