Final answer:
It is generally true that it is unlawful for a pharmacist to refuse to return an unfilled lawful prescription to a patient, as patients have the right to obtain their medication elsewhere.
Step-by-step explanation:
The question relates to the legal obligations of pharmacists concerning the handling of prescriptions. It is generally true that it is unlawful for a pharmacist to refuse to return an unfilled lawful prescription to a patient. If a patient decides not to have their prescription filled, or if the pharmacy is unable to fill it for any reason (such as a lack of stock or the prescription requiring a medication not carried by the pharmacy), the patient has the right to retrieve the original prescription in order to have it filled elsewhere. It is important for patients to have access to their prescriptions, so they can seek fulfillment from an alternative provider ensuring continuity of care.
