That's certainly a possibility here, save for his problems with the DEA. I suspect that your Kansas doctor can no longer prescribe schedule III drugs - those are the druges covered under the Controlled Substances Act.
When I said that "it's complicated", I was alluding to the fact that some states don't recognize the GCM conviction as a felony conviction unless there is a corresponding civilian crime. IOW, there is no civilian equivalent to "desertion", so Kansas may not recognize a conviction on that charge, unlike murder or rape perhaps.
Because Lakin is only charged with 87 & 92, two specs with absolutely no civilian equivalents, this may give him some safe harbor, depending entirely on his licensing state.
And Huet-Vaughan was convicted of desertion, which also has no civilian equivalent, and I think that's the key. All that happened to her was a censure and a fine. She's in family practice and I doubt her ability to prescribe medications, including narcotics, was restricted in any way.
