According to Massachusetts State Pharmacy Law, which mid-level practitioner can prescribe Schedule II controlled substances?

In Massachusetts, both physician assistants and nurse practitioners have the authority to prescribe Schedule II controlled substances, provided they meet certain requirements and have the appropriate collaborative agreements in place. This means they must have established protocols or agreements with supervising physicians, which delineate the scope of their prescribing authority.

Registered pharmacists, under Massachusetts law, have the ability to prescribe under specific conditions, particularly for certain drug therapy management plans or in collaboration with prescribers. However, registered pharmacists generally do not hold independent authority to prescribe Schedule II controlled substances.

Thus, the inclusion of physician assistants and nurse practitioners as mid-level practitioners who can prescribe Schedule II substances, while recognizing the limited role of pharmacists in this specific context, justifies that the broader answer encompassing all of the mentioned practitioners is not accurate.

However, given the nature of the question focusing on mid-level practitioners who can prescribe Schedule II substances, the correct answer stems from the recognized prescribing authority of both physician assistants and nurse practitioners, thus highlighting their role in healthcare delivery.
