Terms

OMMA

The Oklahoma Medical Marijuana Authority, the state agency that licenses patients and businesses and sets the rules for medical marijuana in Oklahoma.

Patient license

The OMMA license a medical patient holds. Oklahoma has issued 24-character license numbers and, since November 2025, 12-character ones.

License status

Whether OMMA shows a license as active. Different from the expiry date: an in-date card can still be not active.

Metrc

The track-and-trace system Oklahoma uses. Licensed businesses report packages, transfers, sales and adjustments to it.

Facility license number

Your business license number. It tells Metrc which facility a request is for.

Metrc user API key

A key generated by a Metrc user that lets software act at your facility with that user's permissions.

Package

A tracked quantity of product with its own Metrc tag, quantity, unit of measure and lab testing state.

Tag

The unique Metrc label that identifies a package.

Unit of measure

How a package is counted in Metrc, for example Each or Grams. Sales must be reported in the package's unit.

Sales receipt

The record of a sale sent to Metrc, listing packages and quantities.

Manifest / transfer

The record of packages moving from one licensee to another. Incoming transfers are checked in when received.

Finished package

A package closed in Metrc because it is empty. Metrc only finishes a package at exactly zero.

Negative balance

A Metrc package showing less than zero, usually from a duplicated or over-reported receipt.

Adjustment

A change to a package's quantity in Metrc with a reason, for example after a count.

Lab testing state

Metrc's record of a package's testing, such as Test passed, Retest passed, Test failed or Testing in progress.

Hold

A block on selling a package. Metrc holds come from a recall, state hold or embargo; stores can also place their own.

Purchase limit

The maximum amount of a product type a patient may take home, set by OMMA.

Unit weight / net weight

The two weights used to count items sold by the each toward a limit.

Reconciliation

Making your shelf, POS and Metrc agree, and explaining any difference.

Override

A manager-approved exception to a check, recorded with who approved it and why.

Recall

A pull of affected packages from sale, with notices to affected patients where needed.
