Narcan

Recently I read a article that I completely agree with.  That article talked about Narcan being a over used drug.  I agree.  Now don't get me wrong it has it's place and i'm all for it there.  However let's say you have a patient that has used heroin,  the patient is alert and answering all questions appropriately,  there isn't a need to administer just because it is a heroin user.  The article was hitting at some providers giving the drug because they can.  I agree that we unfortunately have providers out there that give drugs or do certain treatments because they can.  In my view that is reckless and sets you up for all sorts of issues.  So I guess i short what it comes down to is you have to treat every case differently and don't just automatically assume since it is a heroin user you need to give them narcan.  Especially ALS providers, we can give 0.4 MG for respiratory effect.  So is there a need to give the full 2 MG just because, or can you just stick with the 0.4 MG or what ever it takes to get a respiratory drive back?  It may seem wrong to have them breathing but unresponsive however if the now have a secured airway why risk placing yourself in potential danger by "waking" them up.  Now I realize that people will disagree with me on this however that's my opinion.
