Nevada: from grow to gummy, what ends up on the label

Play it: a flower lot and then a run of gummies move through Nevada's workflow on the left, and each required label piece snaps onto the package on the right, color-coded by who adds it. The lab, not the grower, takes the sample.

The big idea: in Nevada the lab, not the grower, collects the sample, and every certificate of analysis goes to the Board at the same time it goes to the business, pass or fail. A failed lot is destroyed unless a Board agent approves a retest at a lab the agent chooses, and pesticide retests go to the state Department of Agriculture. Edibles carry the outlined "!THC" triangle on every serving, and since 2025 the full consumer label is a store-level duty.

Step by step: Nevada

  1. Step 1: Cultivation / homogenized lot (Cultivation facility) A licensed cultivation facility harvests, tags everything in Metrc, and splits the harvest into homogenized lots: at most 5 pounds of flower under the current rules. A 2025 law, SB 157, lets lots grow to 15 pounds once the Board adopts new sampling rules.
  2. Step 2: The lab collects the sample (Independent lab) The independent lab collects the sample itself and seals it in tamper-resistant packaging carrying the lot's Metrc tag; if the lot is already split into smaller packages, the lab samples every one. The whole lot stays segregated until the certificate of analysis arrives. Using a second lab on the same lot needs Board approval.
  3. Step 3: Full panel, terpenes included (Independent lab) The lab, which must be ISO/IEC 17025 accredited within a year of licensing, runs moisture, potency (THC, THCA, CBD, CBDA, CBN), ten terpenes, foreign matter, mycotoxins, heavy metals, pesticides, herbicides, growth regulators, yeast and mold, Enterobacteriaceae, coliforms, Salmonella, E. coli and four Aspergillus species.
  4. Step 4: COA to the grower and the Board (Independent lab) The lab files the certificate of analysis with the Board at the same time it sends it to the grower, pass or fail, and a pass releases the lot. A fail means destruction unless a Board agent approves a retest, at a lab the agent picks, or remediation of certain failures; failed pesticide tests are retested by the state Department of Agriculture.
  5. Step 5: Gummies: a production run (Production facility) A licensed production facility turns released flower into gummies and packages them on its own premises. The production run number accounts for every lot used, and this is where the label's net weight, ingredients and allergens come from.
  6. Step 6: Run sampled, potency checked (Independent lab) The lab selects a random sample from the production run and verifies the THC is spread evenly: each sample's THC and weight must be within 15% of the target. If any sample fails a test, the whole production run fails.
  7. Step 7: Stamp + package (Production facility) Every serving, 10 mg THC at most and 100 mg per package, is stamped or molded with Nevada's "!THC" triangle. The package says THIS PRODUCT CONTAINS CANNABIS, lists ingredients and allergens, and states the THC with a ±15% allowance.
  8. Step 8: Store label + sale (Retail store) Since 2025 a wholesale package needs only its Metrc tag, so the store affixes or supplies the consumer label if the producer has not printed it: producer and production run, the store's name and address, the lab's cannabinoid profile and Nevada's warnings. It checks ID (21+), sells in opaque, child-resistant packaging, hands over a written warning notice, and must show the certificate of analysis if you ask.

Frequently asked questions

Who tests cannabis in Nevada?
An independent testing laboratory licensed by the Cannabis Compliance Board, which must earn ISO/IEC 17025 accreditation within a year of licensing. For flower it runs moisture, potency, ten terpenes, foreign matter, mycotoxins, heavy metals, pesticides, herbicides, growth regulators and a full microbial panel, then files the certificate of analysis with the Board at the same time it reaches the business, pass or fail.
Who pulls the sample in Nevada?
The lab does. The cultivation facility must let the lab select a representative sample from each homogenized lot, at most 5 pounds of flower under current rules, and the lab seals it with the lot's Metrc tag. For edibles the lab picks a random sample from each production run. The lot stays segregated until the certificate arrives, and a second lab needs Board approval.
What has to be on a cannabis label in Nevada?
A Nevada edible label shows the producer and production run, the store's name and address, the cannabinoid profile from the lab, THC per serving with a 15 percent allowance, ingredients and allergens, net weight, and warnings including THIS PRODUCT CONTAINS CANNABIS. Each serving is stamped with the outlined !THC triangle, and the store adds the label if the producer has not.
Can I ask a Nevada dispensary for the certificate of analysis?
Yes. Nevada's rules require a cannabis sales facility, when a customer asks, to disclose the name of the lab that ran the required quality assurance tests and the matching certificate of analysis. Every sale must also come with a written or electronic notice of the state's required warnings.
What does the triangle on Nevada edibles mean?
It is Nevada's universal cannabis symbol: a white triangle with a black outline, an exclamation mark and the letters THC. It must be stamped, molded or printed with color contrast on every single serving of an edible and may not be modified. Edibles too impractical to stamp, such as powders, are wrapped serving by serving with the symbol on each wrapper, and properly packaged liquids are exempt.
