Can Schedules III, IV, and V controlled substances be stored with Schedule II controlled substances?

Can Schedules III, IV, and V controlled substances be stored with Schedule II controlled substances?

• A. Yes, they may also be stored with Schedule II controlled substances.
• B. No, they must be strictly separated.
• C. Only if stored in a separate vault.
• D. Only if the total quantity is below a threshold.

Answer: (D)

Controlled substances storage is tightly regulated to prevent diversion, with stricter rules for Schedule II. Schedule II drugs must be secured in a way that limits access and keeps them separate from other controlled substances. There is an exception, though: a small amount of Schedule III–V drugs may be stored with Schedule II in the same secure area, but only if the total quantity of Schedule III–V remains below a regulatory threshold. If the combined amount of Schedule III–V would exceed that threshold, they must be stored separately (in a different cabinet or vault). This threshold-based allowance is why the correct answer is that storage with Schedule II is permissible only if the total quantity is below the threshold.
