OMMP Frequently Asked Questions

This page provides answers to some frequently asked questions about the OLCC OMMP Marijuana Tracking Program, about OLCC's role, and about functions in CTS.

A “combined category" product is one that combines usable marijuana, extract, and/or concentrate. For example, buds combined with hash oil would be a “combined category" item. However, shake/trim combined with buds would not be a combined category item because it only includes usable marijuana. A combination of buds with shake/trim should be categorized as shake/trim.

An example of what a “combined category" product would be: Bud (usable marijuana) coated in hash oil (extract) and sprinkled with kief (concentrate.)

An example of what a “combined category" product would not be: bud and shake/trim wrapped in unflavored paper (this should be classified as shake/trim).

For more information on item categorization, see the marijuana product categorization guide.


When creating a “package" in CTS, a user may select one or more source packages and indicate the quantity taken from each to create the new package. When combining multiple items of the same kind, such as multiple strains of tested, usable marijuana, this simply creates a new package. Only identical items may be combined in this way, although the system will not prevent a user from combining non-identical items.

When creating a “new" item by combining different types of marijuana items, the same method is used, but with some additional requirements. For example, creating a “twax joint" (a pre-roll of usable marijuana infused with an extract or concentrate) creates a new “cannabinoid item". In this case, the process or adding two non-similar marijuana items together creates a new “process batch" and the new package must be tracked as such.

Tracking a batch as a “process batch" sets the testing result for the new package to “NotTested." A process batch of a cannabinoid item created from pre-tested marijuana items must be tested for potency prior to transfer to a Retailer.

Note that only a Processor or processing site may make a “process batch."


Marijuana waste is marijuana that is not – or is no longer – usable. At the production/grower level, this typically means the fan leaves (which have negligible THC/CBD), the marijuana stalks, and the stems. However, waste may include usable marijuana that is of low quality or has spoiled, the byproducts of an extraction, or marijuana items that are simply not desirable.

Note that when disposing of waste, marijuana items should be rendered unusable. DEQ guidance provides a number of ways to dispose of marijuana waste, depending on the nature of the product: https://www.oregon.gov/deq/Regulations/Pages/Marijuana-Regulation.aspx

How waste is reported will depend on its source and the stage during the process it was generated.

Immature plants removed from an immature plant batch: If clones or seedlings in an immature plant batch die or are destroyed, they are tracked using the “destroy plants" function. This is a count-based interface and the user simply enters the number of plants destroyed.

Plant material from a live plant: If part of a plant is removed, falls off, or dies other than as part of a harvest and will not be used, it does not need to be tracked in CTS if the plant remains alive.

Wasting a whole tracked plant: If a whole plant must be destroyed and that plant is tracked individually, then the plant must be selected in the appropriate section in CTS and the “destroy plants" option must be used. This requires a reason code to be entered. A note field is included for clarification. The most common destruction reasons are molds or pests

Flower from a live plant: If flower is removed from a live plant and it will be used, this is not waste, it is a manicure harvest. If the flower will be destroyed or discarded, then it is waste from a live plant and does not need to be recorded in CTS.

Waste from a harvest: If waste material (stalks, stems, fan leaves) is removed from a harvest after it is tracked as a harvest in CTS as required, but before it is packaged under UID package tags, that waste must be weighed and reported using the “report waste" function. Because harvests recorded in CTS must be segregated from one another physically, waste must also be reported individually against those harvests.

Waste from a package: If some or all of the marijuana under a package tag is destroyed or damaged, the “adjust packages" function is used to reduce the quantity in the package. A reason code must be selected and a note can be entered for additional clarification.

Byproducts from processing: Usable marijuana used for processing typically results in a cannabinoid concentrate or extract and an amount of “spent" plant material. This waste plant material is not necessarily separately reported into CTS, but is accounted for when creating the process lot. For example, when creating a concentrate or extract in CTS, a source package of marijuana is identified and the quantity that will be used is identified. The difference between the quantity used as a source and the resulting extract or concentrate package is automatically assumed as waste. If this byproduct material will be used, retained, or transferred, then it must be “repackaged" from the original source.


Currently, users may “edit" a strain name, but this will change its value everywhere for that item. Strains are associated only with immature plant batches, vegetative plants, and mature plants. Therefore, if a grower or producer is growing from unknown seeds or “mystery" strains, they can make a “mystery strain" item in their strain list and later change it when they determine the strain. Several such “mystery strains" may be created if needed. (E.g.: “Mystery strain 001," “Mystery strain 002," etc.)

To change a strain after marijuana has been assigned a package tag, the item may be repackaged into a new item type. For example, a package of 10 pounds of an item of the type “Buds (by strain)" that is named “Blue Dream Buds" can be identified as a source for a new 10 pound package of a different item of the type “Buds (by strain)" that is named “Purple Dream Buds". This will require a new tag to be assigned, but items may be repackaged as much as needed.


A marijuana worker permit is not required for a person performing work on behalf of a medical marijuana grow site, processing site, or dispensary.

A marijuana worker permit is required for any person acting on behalf of a recreational marijuana Producer, Processor, Wholesaler, or Retailer who performs any of the following duties or who directly supervises a person performing these duties must have a valid marijuana worker permit:

    • Possessing or handling marijuana items;
    • Tending to plants;
    • Securing marijuana items, including “locking up" the facility or providing private security services (a person performing security services may also need DPSST certification);
    • Selling marijuana items;
    • Documenting any of the above activities;
    • Entering any information into CTS; or
    • Checking ID for the purposes of age verification.

A person without a worker permit may perform any duty on behalf of the licensee that does not include the above.


Visit the Oregon Health Authority's Oregon Medical Marijuana Program website for information on allowable patient transfers of marijuana items.

Information on marijuana testing requirements can be found on the Oregon Health Authority's website.

For a registered OMMP grow site transferring medical marijuana to a patient to whom it belongs, no testing is required. Other transfer types may require testing for pesticides, water activity and moisture content, potency, and residual solvents, depending on the type of marijuana item and the purpose of the transfer.


OLCC has authority to inspect medical marijuana grow sites, processing sites, and dispensaries for possible violations related to the tracking of medical marijuana. OLCC works with the OHA and reports all alleged violations to that agency. OHA is responsible for issuing any sanctions and may also inspect the premises.

A medical marijuana grow site administrator may submit a registration from to OLCC to register for the privilege to transfer up to 20 pounds of usable marijuana to OLCC-licensed Processors and Wholesalers. The limit is 20 pounds annually and is per grow site, not per grower. These transfers are recorded as facility-to-facility transfers in CTS. A grow site may not engage in this privilege until approved by OLCC.

A unique identifier (or “UID") tag is a physical label that is affixed to a marijuana item or quantity of marijuana items that has a printed number and barcode that correspond to that same number in CTS. In CTS, that unique identifier number (or “UID number") is associated with a description of a marijuana item that includes item type, as well as description and quantity, if relevant.

“RFID" refers to “radio frequency identifier". Each UID tag is embedded with an RFID chip that contains encoded information matching the printed number and barcode, which prevents tampering and misrepresentation. A handheld RFID reader can detect these chips and their codes and confirm the information.

UID tags used for tracking in CTS come in two types: plant tags and package tags. Plant tags are used on individual marijuana plants that are flowering or that are over 24 inches in height. The tags will correspond to a value input by the user into CTS that indicates the plant's strain, location, and growth phase (vegetative or flowering.) Plants that are neither flowering nor over 24 inches in height do not require tags and are instead tracked in CTS batches of up to 100 plants, separated by strain (and patient, if relevant.)

When plants are harvested, their tags are “finished" and cannot be re-used. Harvests are tracked in CTS but are not tagged. The weight of each plant is then recorded in a “harvest" in CTS. Once the harvest is dried, usable marijuana is assigned a weight and description in CTS and associated with a new UID package tag that is affixed to the outermost container containing the described quantity of marijuana. New packages may be created by splitting, repackaging, or combining packages within the limitations allowed by rule. Each time a new package is created, it is tracked in CTS and a new UID tag is assigned.

Packages in CTS represent all non-plant marijuana items present at the facility. Packages may transferred to patients or to other facilities through recording a transport manifest.


Yes.

OLCC's cannabis tracking system (CTS) rules require daily reconciliation of marijuana inventory in CTS. This means that at the beginning of each day, inventory should be wholly accurate. Any discrepancies must be reported and any packages adjusted to correct the amounts in CTS. For example, a facility that makes pre-rolled marijuana cigarettes from usable marijuana may “repackage" some quantity of that usable marijuana into a new pre-roll “package" in CTS and the physical process of creating those items may result in some waste, which would need to be reported as a package adjustment to ensure each package reflected the correct weight in CTS.

Similarly if plants die due to pests, mold, or are destroyed for any reason, this information must be entered into CTS by the end of the day in order to meet tracking requirements.

However, there is no “no activity to report" option in CTS. If inventory is the same from day-to-day and the operators have not found any discrepancy, there is no report to make in CTS. Your inventory will remain the same as it appeared when you last logged out.
