Giving narcs

I work as a charge nurse in a LTC facility. Every once in a blue moon, I end up on a med cart, which is great, as I can check up on what meds have/haven't been given, etc. (I've only been doing this for 1 1/2 yrs). My problem is that apparently, I'm the only person who gives out pain pills/other assorted narcs on my shift. I usually give them out to the people who are terminal, or otherwise are unable to adequately tell me how much pain they're in because of dementia, etc. I feel like I'm going to be flagged when state comes in for being the only person who's handing out handfulls of narcs to people who NEED them, but can't express it. I've asked the med nurses to give pain meds to those who (in my opinion) need them because after a year and a half of working closely with these people, I know what their pain symptoms are, but apparently, no one gives anything out, (perhaps out of laziness?). What should I do? Stop giving them myself?

This is my first nursing job, and while I've learned a lot, I still don't know *much* in the grand scheme of things. I'm sorry if this is a stupid question. Like I said, I'm still relatively new at this.
