Schedule II controlled substances CANNOT be transferred in which of the following scenarios?

The transfer of Schedule II controlled substances is heavily regulated due to their potential for abuse and the legal implications surrounding their distribution. The correct answer highlights a scenario where a transfer is not permissible.

In the context of researchers transferring excess Schedule II controlled substances to a pharmacy for dispensing to patients, this violates the regulations set forth by the DEA. Controlled substances, particularly those classified under Schedule II, can only be dispensed for legitimate medical needs by authorized individuals under proper protocols. Typically, substances can only be transferred between entities such as pharmacies, but typically only to a pharmacy license holder for purposes of dispensing to patients, not from a researcher to a pharmacy. This kind of transfer should be conducted through channels specifically designated for the movement of controlled substances, considering the legitimacy of the purpose and parties involved.

Other scenarios presented, while they involve limitations or regulations, can occur under certain conditions. For instance, the return of excess Schedule II substances to a manufacturer or the sharing of prescriptions among licensed practitioners may be governed by protocols and regulatory frameworks that allow them under specific circumstances. Similarly, patients can have their Schedule II medications transferred between pharmacies, provided that both pharmacies comply with applicable laws and policies.
