Oregon: from farm to shelf, what ends up on the label
Play it: the batch moves through Oregon's two-agency workflow on the left (the OLCC licenses the businesses and labs, the Oregon Health Authority writes the testing rules), and each required label piece snaps onto the package on the right, color-coded by who adds it.

The big idea: Oregon splits the job between two agencies: the Oregon Health Authority writes the testing rules and accredits the labs, while the OLCC licenses the businesses and the labs and writes the label rules. Only a lab employee can take the sample, a pass after a failed test must be confirmed by a second lab, and the label has to name who tested it and when. The OLCC can also audit-test potency and order the label changed.

Step by step: Oregon
- Step 1: Harvest lot into batches (Producer) An OLCC-licensed producer splits each harvest lot into batches of 50 pounds or less, gives each a unique batch number, records it in Metrc, the OLCC's seed-to-sale system, and orders testing (a licensed wholesaler may order it instead). This becomes the label's producer, UID, strain and harvest date.
- Step 2: A lab employee samples (Accredited lab) Only employees of a lab accredited for sampling may take samples, at the licensee's premises, or the licensee brings the entire batch to the lab. The whole batch must be available, in containers of 15 pounds or less, and the increments must add up to at least 0.5% of the batch.
- Step 3: Compliance panel (Accredited lab) The lab, accredited by ORELAP (the Oregon Health Authority's accreditation program) and licensed by the OLCC, tests every batch for pesticides, water activity and moisture, potency (delta-9-THC, THCA, delta-8-THC, CBD, CBDA), heavy metals, mycotoxins and microbes, and enters the results in Metrc.
- Step 4: Fail, reanalyze, confirm (OLCC / OHA) A failed sample may be reanalyzed by the same lab, but if it then passes, a second lab, under different ownership, must resample the batch and confirm the pass. The batch must stay whole while that happens. A batch that fails microbial testing can be sterilized or extracted and then retested; anything not remediated is destroyed.
- Step 5: Package + label (Packager) The packager labels the container: producer and license, the packager if different, the Metrc UID, harvest date, strain, net weight in grams and ounces, THC and CBD exactly as the lab calculated them, and the name of the lab and the test date.
- Step 6: Universal symbol + warnings (OLCC / OHA) The principal display panel carries the product identity, the net quantity and Oregon's universal symbol, at least 0.48 by 0.35 inches and never recolored or reshaped, plus two warnings about age and driving. A target potency on the label may not differ from the lab's value by more than 10%.
- Step 7: Retail check + sale (Retailer) If an item arrives mislabeled, the retailer must notify the OLCC and either return it or add only the missing label components with a sticker. At the time of sale it hands every customer the state's Marijuana Information Card.
- Step 8: OLCC audit testing (OLCC / OHA) The OLCC can require any licensee to submit samples to labs of its choosing. If audit results differ from a batch's original potency test with statistical significance at the 99% level, it can order the batch relabeled with the audit average.
Frequently asked questions
Who tests cannabis in Oregon?
A laboratory accredited by ORELAP, the Oregon Health Authority's accreditation program, and licensed by the OLCC. It tests every batch of flower for pesticides, water activity and moisture, potency (delta-9-THC, THCA, delta-8-THC, CBD and CBDA), heavy metals, mycotoxins and microbial contaminants, and enters the results in Metrc. A pass after a failed test must be confirmed by a second lab.
Who pulls the sample in Oregon?
Only an employee of a laboratory accredited for sampling may take samples, either at the licensee's premises or after the licensee brings the entire batch to the lab. Flower batches can be up to 50 pounds, held in containers of 15 pounds or less, and the sample increments must add up to at least 0.5 percent of the batch.
What has to be on a cannabis label in Oregon?
An Oregon flower label shows the producer's name and license number, the packager if different, the Metrc UID, harvest date, strain, net weight in grams and ounces, THC and CBD as calculated by the lab, the name of the lab and the test date, the universal symbol, the product identity, and two warnings about age and driving.
Can the state change the THC number on an Oregon label?
Yes. The OLCC can require any licensee to submit samples for audit testing at labs it chooses. For batches with a potency test on or after 1 December 2022, if the audit results differ from the original result with statistical significance at a 99 percent confidence level, the OLCC can order the batch relabeled with the average audit result.
What does Oregon's universal symbol look like?
It is a rounded black rectangle with a white exclamation mark on the left and a red panel holding a white cannabis leaf on the right. It must appear on the principal display panel, at least 0.48 inches wide by 0.35 inches high, and may not be modified in color or shape. Hemp items use a separate hemp symbol.
