Inventory and waste are one chain

Inventory and waste are the same compliance question at two points in a product’s life. A regulator expects the licensee to know what it holds, where it is, what happened to it, and how the record closed when product was sold, transferred, returned, destroyed, or discarded. Audit the whole chain, not inventory and waste as separate departments.

Start with a three-way reconciliation of a representative inventory population: the physical count, the state tracking system, and any internal ERP, manufacturing, or point-of-sale system. The three should agree or have a documented, authorized explanation. A spreadsheet that balances to the state system but not to the room is not a reconciliation.

Reconciliation and adjustments

• Name an inventory-control owner for each facility and a backup who can reconcile when the owner is away.
• Reconcile physical inventory, the state system, and internal records on the cadence the license requires: weekly for Illinois craft growers and cultivation centers, daily for Illinois dispensaries, and with a monthly physical inventory report in Missouri.
• Separate expected process and moisture loss from unexplained variance, and record the conversion or yield basis used.
• Investigate negative quantities, duplicate packages, orphaned tags, stale packages, open harvests, and impossible quantities promptly.
• At an Illinois dispensary, obtain IDFPR approval before any inventory adjustment and keep the documentation at the dispensary for two years.
• In Missouri, document, investigate, and report a discrepancy within 24 hours before correcting it through an adjustment.
• Review each manual adjustment for reason, evidence, approver, user, date, and whether notice applies.

Transfers and receipts

• Match incoming transfers to manifests, receiving records, package identifiers, quantities, and acceptance or rejection decisions.
• Match outgoing transfers to the authorized destination, transporter, manifest, package status, departure, and receipt.

Waste creation and destruction

• Create waste in the tracking system when product becomes waste, not later during administrative cleanup.
• Weigh, record, and enter waste in the system before mixing it, with supervisor verification under video surveillance in Illinois.
• Give the Illinois Department of Agriculture and the Illinois State Police at least seven days’ notice before destroying cannabis at a supply-side facility, and hold product if the Department requires it.
• At an Illinois dispensary, give IDFPR and the Illinois State Police the weekly destruction day and time, with three business days’ notice of any change.
• Render cannabis waste unusable by grinding it into a mixture that is at least 50 percent non-cannabis waste by volume unless another method is approved.
• Classify each waste stream as cannabis waste, liquid waste, hazardous waste, or ordinary solid waste before choosing a disposal route.
• In Missouri, record the date, time, location, the two cameras that captured the destruction, the method, the mixing medium, and the agent identification numbers in the destruction log.
• Keep the vendor, destination, date, quantity, method, and proof of final disposition, and retain destruction records for at least five years.

Exceptions and permissions

• Resolve failed, recalled, expired, returned, damaged, contaminated, and sample material so none remains in an unresolved status.
• Compare system and vault permissions with current job duties, and remove access promptly when roles change.
• Trend variances and waste ratios by room, product, shift, or process when the data supports comparison, and keep corrective-action evidence for recurring variances.

Illinois tracking and reconciliation duties

The Department of Agriculture’s tracking subpart, effective May 1, 2026, makes the state plant monitoring system the system of record and requires all cannabis in the enclosed, locked facility to be tracked at all times, with accurate and complete data (8 Ill. Adm. Code 1300.1000). Reportable activities include receipts, rejected transfers, changes in form or category, destruction or waste, packaging, sales, harvests, internal moves, and plantings, recorded upon completion (8 Ill. Adm. Code 1300.1030). Craft growers must keep a plant monitoring system with a physical inventory recorded weekly (410 ILCS 705/30-30(a)), and cultivation centers have parallel duties.

Dispensaries reconcile daily, comparing the State verification system, the point-of-sale system, and physical product. IDFPR must approve any inventory adjustment in advance. If the cause of a mistake-based imbalance is not found within two calendar days of discovery, the dispensary tells IDFPR in writing, and theft is reported to IDFPR and the Illinois State Police within 24 hours (410 ILCS 705/15-75(d), 68 Ill. Adm. Code 1291.310).

Illinois destruction and disposal

On the supply side, cannabis waste must be stored, secured, locked, and managed under state rules and the approved operations plan, rendered unusable before it leaves the facility, and disposed of at a permitted solid waste facility such as a compost facility, anaerobic digester, landfill, or incinerator. Liquid waste follows the Environmental Protection Act and hazardous waste follows federal, state, and local law (8 Ill. Adm. Code 1300.800, 1300.840). At least seven days before rendering product unusable and disposing of it, the licensee notifies the Department and the Illinois State Police, and the Department may send an employee to witness the destruction or require the product to be held for up to seven days (8 Ill. Adm. Code 1300.810). Waste may not be sold, and it must be weighed, recorded, and entered into the inventory system before mixing or disposal, with supervisor verification in an area under video surveillance (8 Ill. Adm. Code 1300.840).

Dispensaries follow IDFPR’s rule. The dispensary gives IDFPR and the Illinois State Police its weekly destruction day and time at the initial registration inspection and gives at least three business days’ notice of a change. Flower destruction is performed by or under the supervision of the agent-in-charge, under video surveillance, after the flower is weighed, recorded, and entered into the State verification system. Waste is rendered unusable by grinding it with other materials into a mixture that is at least 50 percent non-cannabis waste by volume unless IDFPR approves another method, and destruction records are kept for at least five years (68 Ill. Adm. Code 1291.325).

Missouri tracking and waste

Missouri makes the statewide system each licensee’s system of record and requires product to be traceable at all times. Discrepancies are documented, investigated, and reported within 24 hours before correction, licensees file a monthly physical inventory report, and records are kept at least five years (19 CSR 100-1.130). Each licensee must evaluate its waste under the federal hazardous waste determination rule. Plant material is not hazardous in itself unless treated or contaminated, but solvents, pesticides, laboratory waste, and failed extract must be evaluated. Nonhazardous plant waste must be rendered unusable before leaving the facility by grinding it and mixing it with other nonhazardous material so the result is at least 50 percent non-marijuana waste by volume. Other methods and destinations need written approval. The destruction log records the date and time, location, the two cameras that captured the destruction, the method, the mixing medium, and the agent identification numbers (19 CSR 100-1.150). The Missouri text was read from a reproduction current through June 2025, so confirm it against the rules effective May 30, 2026.

Separate finding a variance from erasing it

The person who finds a variance should not automatically be able to erase it. Use role-based permissions and, for material corrections, an approval step that requires a reason and evidence. In Illinois dispensaries that approval is IDFPR’s, not management’s. For waste, the employee creating it records the source and quantity, while closing the destruction record can require the supervisor verification the Illinois rules call for. When the audit finds one user who can create product, adjust it, mark it as waste, and close the destruction record without review, management should decide whether stronger separation of duties is needed. Our seed-to-sale guide explains the reporting deadlines behind these controls.
