Step-by-step explanation:
The statement you've provided suggests a discussion about the regulatory requirements of prescribing medications or controlled substances. In the United States, prescribers are required to provide detailed documentation when issuing prescriptions for certain substances. This is particularly true for controlled substances, which are governed by strict federal regulations. These regulations are in place to prevent abuse and ensure that the drugs are used safely and appropriately. Such documentation might include an invoice or other federally required forms that must be completed and submitted by the prescriber to the relevant authorities for verification and record-keeping purposes.
