Hong KongDestruction
Destruction of controlled substances is governed by 21 CFR Part 1317, which sets out authorized methods and the requirement that the substance be rendered non-retrievable.
One of two disposal regimes a pharmacy operates under, and the exam cares that you know they are two.
The standard
A controlled substance must be rendered non-retrievable. Part 1317 of 21 CFR governs disposal and sets out the authorized routes. No record, no proof.
Non-retrievable is the operative concept: the substance must be permanently altered so it cannot be recovered or used.
Putting a controlled substance in ordinary waste leaves it retrievable, which is the failure the rule addresses. And the environmental route is regulated separately in any case, so an act that seems to solve the DEA problem may create an EPA one.
Two regimes, one drug
| Concern | Regime | Where |
|---|---|---|
| Diversion | DEA | 21 CFR 1317 |
| Environmental hazard | EPA | 40 CFR 261, including the P and U lists |
A drug can fall under both, and then both apply. Questions mixing them are testing whether you know they are separate systems. Non-retrievable is the standard.
Take-back
Authorized collection arrangements allow controlled substances to be returned for destruction, which is how patient-returned medication is handled where a pharmacy participates. Two regimes, one drug.
Whether a pharmacy may accept returns, and how, depends on its registration and on the applicable rules.
What a technician does
- Follows the pharmacy's documented procedure rather than improvising
- Records what was destroyed, how and when
- Ensures witnessing requirements are met where they apply
- Never disposes of a controlled substance outside the procedure
Documentation, again
Destruction records join the recordkeeping obligation. Something destroyed without a record is indistinguishable from something missing.
Common questions
How are controlled substances destroyed?
By an authorized method rendering them non-retrievable, under 21 CFR Part 1317.
Can I flush or bin them?
No. That leaves them retrievable and may create an environmental violation.
Is this the same as hazardous waste disposal?
No. Destruction is DEA under 21 CFR 1317; hazardous waste is EPA under 40 CFR 261. A drug can fall under both.
What about patient returns?
Handled through authorized collection arrangements, depending on the pharmacy's registration.
Why does documentation matter?
Something destroyed without a record is indistinguishable from something missing.
