Hong KongWitnessed controlled-substance breakage versus missing stock
A witnessed breakage or spill is an accountable, documented destruction event; it is not automatically theft or a reportable significant loss.
More key points
- An unexplained shortage is an inventory discrepancy that must be investigated, reconciled, and assessed for significance under DEA rules.
- Never use a breakage explanation unless the event was actually observed and properly documented.

A controlled-substance count is short by one unit. Was a tablet dropped and destroyed in view of a witness, or is the unit simply unaccounted for? Those situations can lead to different records and reporting decisions. The exam distinction is evidence: a documented destruction event is not the same as an unexplained loss.
What a witnessed breakage establishes
If a controlled substance is accidentally broken, spilled, or otherwise rendered unusable, staff should secure the material, follow the employer's controlled-substance procedure, and create a contemporaneous record. The record should identify the drug and strength, quantity, date and place, circumstances, people involved, and how the material was rendered unrecoverable or disposed of. A witness provides corroboration; the witness does not replace the required inventory and destruction documentation.
DEA guidance says that breakage or spillage witnessed by another person does not by itself need to be reported to DEA as a theft or significant loss. That does not make it a no-record event. State pharmacy law, board rules, facility policy, and the registrant's procedures can impose additional documentation, witnessing, or disposal steps. Follow the applicable procedure and retain a clear audit trail.
A discrepancy discovered during a count is not witnessed breakage. Reconcile records, inspect the work area and transaction history, interview relevant staff, and document what is known. Do not backfill a destruction record without evidence that destruction occurred.
What to do with a missing unit
- Protect the remaining stock and preserve the records, counts, access logs, dispensing transactions, and relevant video or reports under policy.
- Repeat the count with an independent person and check the correct drug, strength, dosage form, package size, and inventory unit.
- Trace receipts, dispensing, returns, transfers, compounding, waste, and prior adjustments. Check for data-entry or package-conversion errors.
- Record the discrepancy and the investigation steps, findings, unresolved amount, and people notified.
- The DEA registrant or responsible compliance lead evaluates whether the facts indicate theft or a significant loss and completes any required notifications and reports on the applicable timelines.
Federal rules require registrants to notify the DEA field division in writing of a theft or significant loss within one business day of discovery and to submit DEA Form 106 for a theft or significant loss. The significance assessment is fact-specific; quantity alone is not the sole consideration. State and employer procedures may require immediate internal escalation even when the federal reporting threshold is not ultimately met. Do not delay internal reporting while deciding whether the event meets the federal definition.
| Situation | What the evidence says | Core response |
|---|---|---|
| Tablet visibly falls and is destroyed, with a witness | A specific loss event and quantity are observed | Secure, document, witness and dispose under applicable procedures; assess any state or facility reporting rules |
| Count is short and no one saw destruction | The cause is unknown | Recount, reconcile, investigate, document and escalate for significant-loss assessment |
| A broken package is found later, amount uncertain | Possible loss, but the quantity and timing are not established | Preserve evidence, determine what can be established, document uncertainty and escalate |
| Transaction shows a reversed dispense but physical stock was not checked | Possible record error or actual shortage | Verify physical inventory and source records; do not assume either explanation |
Why the distinction matters
Controlled-drug accountability depends on a traceable explanation for every adjustment. A witnessed breakage record supports an observed event. A missing-stock investigation tests whether a transaction, counting, packaging, diversion, or destruction issue explains the discrepancy. Treating the two as interchangeable weakens the record and may conceal diversion.
Exam-ready distinctions
- Witnessed breakage is documented destruction; a shortage with no observed event is an unresolved discrepancy.
- A witness supports the account of the event but does not eliminate documentation or disposal requirements.
- Not every discrepancy is automatically a federally reportable significant loss, but every discrepancy deserves timely reconciliation and escalation under policy.
- The registrant is responsible for required DEA notifications and reports; staff should report promptly through the designated process.
- Federal guidance does not displace stricter state rules or workplace procedures.
A quick example
A technician drops a sealed vial, and the pharmacist observes the vial shatter. The staff secure the area, account for the entire contents, document the event and witnesses, and destroy the unusable material following policy. That record supports witnessed breakage. If the next inventory is short by a vial and no one observed what happened, the pharmacy investigates the discrepancy; it cannot convert the shortage into witnessed breakage by writing a similar form afterward.
For PTCE questions, ask what is actually known: was the breakage observed and the quantity accounted for, or was a count discrepancy discovered later? Choose the response that preserves evidence, documents the event, and escalates an unexplained loss for investigation.
Common questions
Does witnessed controlled-substance breakage require DEA Form 106?
DEA guidance says witnessed breakage or spillage alone is not a theft or significant loss report to DEA. The event still requires documentation and may be subject to state, board, or employer procedures.
What should a pharmacy do when controlled-drug stock is missing?
Secure the stock and records, recount, reconcile transactions, investigate and document the discrepancy, then have the registrant assess whether it is a theft or significant loss requiring DEA and state reports.
Can a pharmacy document breakage after discovering a shortage?
Only if evidence establishes that breakage actually occurred. An unexplained shortage should remain documented as a discrepancy while it is investigated.
Who files the DEA significant-loss report?
The DEA registrant has the federal responsibility for required notification and Form 106. Staff should promptly follow internal escalation procedures.
