Why don't CRNAs have prescriptive authority like NPs?

I wanted to ask why in many states CRNAs do not have prescriptive authority like nurse practitioners. I would assume they are able to as most are autonomous providers. Thanks in advance!

Based on my discussion with many crnas and in working with them often as well as anesthesia pain services nearly daily I do not think crnas working in chronic pain management would be appropriate unless their education changes. Evens anesthesia MDs do a separate fellowship for pain management.

Yes but according to the nursing armada a 20 hour certification course = fellowship

Okay. So it sounds like CRNAs can obtain prescriptive authority, many just don’t want it. Hmm. 

affirmative.

Maybe that’s why the VA didn’t grant them FPA and did for all other APRN roles.

Can you give me an example of a scenario in which a CRNA would want to dispense a prescription?  We have the authority to "dispense and administer" drugs during the operative process.
