I think you totally miss the point of having IN narcan in the hands of basic EMT's or cops. There are NUMEROUS reports of saves by LE who are first on the scene with an OD. They aren't going to have good (if any) airway skills. For that matter, most non-anesthesia folks have horrible BVM skills, and you certainly won't learn that in a four hour class. However, a good four hour class for using IN narcan is going to be a cheap way to save some lives - it already has. They're on the news when their department gets it and on the news when they have a save.
Ventilation in a narcotic OD does NOT revive apneic or near-apneic patients. They are not going to wake up just because you're ventilating them. You need to think about that statement again. If they do, then narcotic OD wasn't their problem to begin with.
Do we use "meds before electricity"? Hmmmmm. Think about that statement again as well and perhaps go back and review your ACLS.
Not sure how long you've been doing this, but I suspect narcan has been around a lot longer than you, so I'm not sure how you can have a problem with the way it came about, and considering it's success, I'm not sure how you can have a problem with how it's used - except that you're getting beat to the punch on a save by a cop with a four hour narcan course. IMHO
