Final answer:
Foreign prescribers cannot write prescriptions for controlled substances to be dispensed in Arizona. Prescriptions must be issued by individuals registered and licensed in the U.S. Some rare exceptions may apply in emergency treatment or international agreements.
Step-by-step explanation:
It is false that prescribers from outside the United States may write controlled substance prescriptions for dispensing in the state of Arizona. According to U.S. federal law and Arizona state regulations, a prescription for a controlled substance must be issued by a medical professional who is registered with the DEA (Drug Enforcement Administration) and licensed to practice in the U.S. Foreign prescribers do not have the authority to prescribe controlled substances that can be legally dispensed by pharmacies in Arizona.
Exceptions to this regulation could include situations where a foreign prescription may be considered valid if it is part of a specific international agreement or if the patient is receiving emergency treatment while in the U.S. However, such situations are exceptions to the general rule and typically involve additional validation steps.
