Why waste Narcan?

I have saved 2 over doses? (3 maybe), and never with Narcan, but I would have for sure used it on two of the cases. Also, pandemic, not every one has a mask, and the EMT is gonna do it anyway, do why not?

My point is I disagree, carry two isn't hard, and most ODs I've seen still have the needle right there, its not just a guess.
