Medication refill

A parent approaches you, the pharmacy technician, with a request to refill her son’s Adderall prescription. She does not have a new prescription with her, but explains that she has had it filled in this pharmacy the first time.

In your initial post:

Define the classification of the medication.
Define the list of controlled substances, and where Adderall would be found in this list.
Explain why this medication cannot be dispensed to the mother.
