The "schedule II drugs" jeherr mentions as being counted twice are things like cocaine, methamphetamine and fentanyl. i.e. drugs that could be readily sold onto the black market.
While cocaine and methamphetamine are schedule II, those are poor examples. I don’t think pharmacies ever carry them, and their medical use is very rare.
Fentanyl is commonly carried in pharmacies but it’s not a commonly prescribed medication. Better examples would be adderall, vyvanse, norco and oxycontin.
