Well, not-really-OPs locale (presumably) has an opiate problem, tried Narcan, and saw that it didn't work too well. I am simply responding to your statement that poor training does not negate practicality, because if you don't actually properly administer the medication (spraying it over the patient's face), then it has no use, therefore, its functionality is negated. Nowhere did I say that they should abandon Narcan or that it can't work, but it currently doesn't work, and that should be recognized.
