| Every cannabis product sold at a licensed Nevada dispensary is tested by an independent, state-licensed laboratory before it reaches the shelf. That testing confirms how much THC and CBD a product contains and screens it for contaminants like pesticides, heavy metals, and mold. At The Grove, the same standard applies to the flower, concentrates, and edibles we grow and produce ourselves, and to every outside brand we carry. |
Key facts about lab-tested cannabis in Nevada
- Testing is mandatory: cannabis cannot be sold in a licensed Nevada dispensary until it passes lab testing.
- Testing is independent: the lab is licensed by the Nevada Cannabis Compliance Board (CCB) and is separate from the grower and the store.
- Labs are accredited to the international ISO/IEC 17025 standard for testing laboratories.
- Every batch is screened for potency and for contaminants before it can be packaged for sale.
- The label must show tested potency, with an allowable variance of plus or minus 15 percent.
- The Grove grows its own cannabis in a 26,600 square foot indoor facility, so its house products are tested from seed to shelf.
- The live menu lists tested cannabinoid content, terpenes, and effects for each product in stock.
What Nevada requires before cannabis can be sold
Nevada law requires laboratory testing on all regulated cannabis. The Cannabis Compliance Board licenses independent testing laboratories and sets the standards those labs follow, which means the company that tests a product is not the company that grew or sold it. A licensed lab in Nevada holds ISO/IEC 17025 accreditation, the international standard for testing and calibration laboratories, and follows recognized methods for cannabis analysis.
This structure exists so that safety and potency are verified by a neutral third party rather than claimed by the seller. A product that fails testing cannot be sold. For a shopper, the practical takeaway is simple: if a product is on the shelf at a licensed store, it has already passed the state’s testing requirements.
What lab testing checks
Lab testing measures two things: what is in the product, and what should not be. On the potency side, labs profile the cannabinoids, including THC, THCA, CBD, CBDA, CBN, and CBG, and they measure terpenes, the compounds that shape a strain’s aroma and character.
On the safety side, testing screens for contaminants across several categories. Nevada labs check for pesticide residue against a state list of more than 60 banned pesticides, for heavy metals such as arsenic, cadmium, lead, and mercury, and for microbial contamination including yeast, mold, coliforms, E. coli, Salmonella, and Aspergillus. Labs also test for residual solvents, mycotoxins, moisture content, and water activity. Each category has a defined limit, and a product that exceeds a limit does not pass.
How to read the label and the live menu
The label and the menu translate lab results into information you can use before you buy. Nevada requires the tested potency to appear on the package, so the THC and CBD figures on a label come from the lab, not from the brand’s marketing. Potency is reported with an allowable variance of plus or minus 15 percent, which is why a label figure is a tested measurement rather than an exact promise for every gram.
Our real-time menu carries the same detail online. For each product in stock, the live menu lists cannabinoid content, terpenes, and reported effects, along with THC, CBD, and other amounts in milligrams, plus the brand information each supplier provides. You can compare products on those numbers before you visit, whether you are shopping the Las Vegas store at 3 a.m. or the Pahrump counter during the day.
Where The Grove’s products come from
The Grove grows its own cannabis, which changes what testing means for our house products. Every plant starts in our 26,600 square foot indoor cultivation facility, where our master grower uses all-natural soil and natural pest and fungus control with no synthetic shortcuts. Because we control the plant from seed to shelf, lab testing verifies work we did ourselves rather than a batch we bought sight unseen.
We also carry a curated selection of other Nevada brands, and those products meet the same state testing requirements before we stock them. Growing our own does not mean we only sell our own; it means the flower, concentrates, and edibles that carry The Grove name are ours end to end, and everything else on the menu still clears the same bar.
Testing, limits, and shopping responsibly
Lab testing and purchase limits are the two parts of Nevada’s system that a shopper meets directly. Testing governs what is in a product; purchase limits govern how much of it you can buy in a single transaction. Both are set by the state, and both apply the same way at either of our stores. You can review the specifics on our guide to Nevada cannabis purchase limits.
Reading the tested numbers is the practical way to shop within your own comfort level. A first-time edibles buyer and a daily flower smoker are working from very different starting points, and the milligram and percentage figures on the label and menu are there to help each of them choose deliberately.
What lab testing does and does not tell you
A passing lab test tells you a product meets Nevada’s safety limits and that its potency is accurately labeled. It does not tell you how that product will affect you. Response to cannabis varies from person to person and depends on dose, tolerance, product type, and other factors, so the same tested product can feel different for two people.
Testing also is not medical guidance. The numbers describe the contents of the product, not a health outcome, and cannabis products are not evaluated by the FDA to diagnose, treat, cure, or prevent any condition. If you have questions about how cannabis fits your own situation, that is a conversation for a physician. What we can do is make sure the product information in front of you is accurate and complete, and help you read it.
Frequently asked questions
Is all cannabis sold in Nevada lab tested?
Yes. All regulated cannabis sold in licensed Nevada dispensaries must be tested by an independent, CCB-licensed laboratory before it can be sold. A product that does not pass cannot go on the shelf.
What do Nevada labs test for?
Labs test for cannabinoid potency, such as THC and CBD, and for terpenes. They also screen for contaminants, including pesticides, heavy metals, microbials like mold and Salmonella, residual solvents, mycotoxins, and moisture or water activity.
What does the THC percentage on the label mean?
It is the potency measured by the lab, reported on the package as Nevada requires. Nevada allows a variance of plus or minus 15 percent, so treat the figure as an accurate tested measurement rather than an exact guarantee for every gram.
How can I see a product’s tested numbers before I buy?
Our real-time menu lists the tested cannabinoid content, terpenes, reported effects, and THC, CBD, and other amounts in milligrams for each product in stock, along with the brand detail each supplier provides. You can review it online before you visit either store.
Does lab tested mean a product is safe for everyone?
Lab tested means a product meets Nevada’s contaminant limits and is accurately labeled for potency. It does not mean a product is right for every person. Effects vary by individual and by dose, and product information is not a substitute for advice from a physician.
