Every cannabis product sold at an OLCC-licensed Oregon dispensary must carry a standardized label with specific information required by state regulations. Understanding what each element on the label means helps you make informed purchasing decisions, dose accurately, and consume safely. Oregon's labeling requirements are enforced through the OLCC's regulatory framework and verified through the Metrc seed-to-sale tracking system.

Required Label Information

Oregon Administrative Rules (OAR 845) mandate that all cannabis product labels include:

• Product name and brand — The product's commercial name and the licensed producer, processor, or retailer
• OLCC license number — The license number of the business that produced or packaged the product
• Net weight or volume — The total amount of product in the package
• THC and CBD content — Total milligrams per package, and per serving for edibles
• UID (Unique Identification) number — The Metrc tracking tag that traces the product through the entire supply chain
• Testing laboratory — The name of the ORELAP-accredited lab that tested the product
• Harvest or production date — When the product was harvested (flower) or manufactured
• Ingredients list — All ingredients for manufactured products like edibles, tinctures, and topicals
• Universal symbol — The Oregon cannabis warning symbol indicating the product contains THC
• Required warnings — Health warnings including impairment and pregnancy advisories

Understanding Potency Numbers

Potency is the most important number on a cannabis label, but it is expressed differently depending on the product type:

Flower and Pre-Rolls

Potency is listed as a percentage of THC by weight. A product labeled "24% THC" contains 24 milligrams of THC per 100 milligrams of dried flower. A typical joint contains about 0.5 to 1 gram, so at 24% THC, that equals roughly 120 to 240 mg of total THC — though only a fraction is absorbed when smoked. Oregon flower averages $3.33/gram at retail, making it easy to experiment with different strains affordably.

Edibles

Potency is listed in milligrams of THC per serving and per package. Oregon caps recreational edibles at 100 mg per package with individual servings of 10 mg maximum. A common configuration is 10 gummies of 10 mg each. For new consumers, 2.5 to 5 mg is generally considered a starting dose. Medical patients can purchase edibles at 100 mg per package with no per-serving restriction.

Concentrates and Vapes

Potency is listed as a percentage of THC, similar to flower but typically much higher — often 60% to 90%. Some labels also show total milligrams. Due to their high potency, concentrates are recommended for experienced consumers only.

Tinctures

Potency is listed in milligrams per dropper (serving) and per bottle. Recreational tinctures follow standard potency limits, but medical tinctures can contain up to 4,000 mg of THC per container. Labels will specify the THC:CBD ratio if the product contains both cannabinoids.

Terpene Profiles

Many Oregon products — especially those from craft producers — list terpene content on the label. Terpenes are aromatic compounds that contribute to a strain's smell, flavor, and potentially its effects. Common terpenes include:

• Myrcene — Earthy, musky; the most abundant terpene in cannabis
• Limonene — Citrus aroma; associated with uplifting effects
• Linalool — Floral, lavender; associated with calming effects
• Caryophyllene — Peppery, spicy; the only terpene known to interact with cannabinoid receptors
• Pinene — Pine aroma; associated with alertness

Oregon's craft cannabis culture has pushed many producers to emphasize terpene-rich, full-spectrum products over THC percentage alone. The Cultivation Classic competition judges entries on terpene profiles, not just potency — a reflection of Oregon's maturing consumer base.

Warning Labels and Symbols

Oregon requires several standardized warnings on all cannabis packaging:

• Universal cannabis symbol — A standardized graphic indicating the product contains THC
• "Keep out of reach of children" — Required on all products
• Child-resistant packaging — All products must be sold in child-resistant containers
• Government health warning — Statements about the risks of cannabis use, including impairment and pregnancy warnings
• "For use only by adults 21 and older" — Age restriction notice on recreational products

Metrc Tracking and Batch Numbers

Oregon uses Metrc (Marijuana Enforcement Tracking Reporting and Compliance) as its seed-to-sale tracking system. Every cannabis product carries a unique identification (UID) number that links back to:

• The specific production batch and its laboratory test results
• The cultivator who grew the plant material
• Every transfer between licensed businesses in the supply chain
• The Certificate of Analysis (COA) from the ORELAP-accredited testing lab

Some Oregon brands provide access to full COAs via QR codes on their packaging. Scanning the code gives you the complete lab report, including exact potency numbers and all contaminant screening results. If product transparency matters to you, look for brands that make this information readily available.

Medical vs. Recreational Labels

Medical and recreational products carry similar labeling requirements, but there are important distinctions:

• Medical products may carry additional dosing guidance and higher potency limits
• Medical patients can possess up to 24 ounces (vs. 1 oz public / 8 oz home for rec)
• Medical products are exempt from all cannabis taxes (17% state + up to 3% local)
• Medical tinctures can contain up to 4,000 mg THC
• Packaging for medical products is identified as part of the Oregon Medical Marijuana Program (OMMP)
