In one of those things I don’t really get*, Texas requires a separate license from an unrestricted medical license to prescribe narcotics. As the price of this extra license has always seemed to be more ‘cover the cost’, nobody has seriously objected. It’s $25, in case you’re interested.
Since it’s a State license, it’s required if your job could even perceivably need to prescribe narcs in a hospital. (So, Radiologists and Pathologists are usually exempted). It’s never been an issue, as long as you don’t screw up.
