COA & QA Results

Ever wondered what's in your cannabis? Take a look below!

Explore cannabis Certificates of Analysis (COAs) and QA test results for products at Uncle Willie’s Cannabis. Search by vendor, product, strain, or External Identifier / SKU to find the corresponding certificate and view the available laboratory report. Our searchable cannabis testing table makes product information easier to access in one convenient place.

Access to cannabis lab test results helps consumers make informed choices about the products they purchase or have purchased. A Certificate of Analysis can provide cannabinoid potency information, including THC and CBD levels, along with the results of contaminant testing included in that report.

Reviewing the certificate that matches your product’s identifier gives you a clearer understanding of its tested contents, beyond the strain name or packaging alone.

How to Read Cannabis Test Results

A Simple Guide to Certificates of Analysis

A Certificate of Analysis (COA) is a laboratory report showing a cannabis sample’s potency and contaminant test results. Here’s what to look for when exploring the test results at Uncle Willie’s Cannabis.

Match Your Product

Check the product name, producer, and batch or lot number against your packaging. Different batches of the same strain can have different results. Check the testing date, too.

Check the Safety Results

Review the individual categories for pesticides, heavy metals, microbes, mold-related toxins, and residual extraction solvents.

  • PASS: The sample met the applicable criteria for that test.

  • FAIL: The sample did not meet the applicable criteria.

  • NT — Not Tested: No result is provided for that category on this report.

Read each category—not just the overall “PASS.” Some testing results may appear on separate reports.

Understand the Potency Numbers

Total THC includes THC already present plus the potential THC produced when THCA is heated. Total CBD similarly accounts for CBD and CBDA.

MeasurementWhat It Means
%Concentration. For example, 20% equals 200 milligrams per gram.
mg/gMilligrams per gram of tested material—not necessarily per serving.
mg/servingMilligrams in one serving, when provided.
mg/packageMilligrams in the entire package, when provided.

Total cannabinoids is not the same as total THC. It includes other cannabinoids, and the calculation can vary by report. Higher THC alone does not tell you everything about a product’s quality or effects.

Beyond THC: 11 Cannabinoids to Know

CBD and minor cannabinoids provide a fuller picture of a product’s chemical profile. Research is still developing, especially for cannabinoids present in small amounts.

CannabinoidWhat to Know
CBD — CannabidiolDoes not produce the characteristic THC high. A prescription form treats certain seizure disorders; other potential benefits remain under study. CBD can interact with medications.
CBG — CannabigerolEarly human research suggests possible effects on stress and anxiety. More research is needed.
CBN — CannabinolForms as THC breaks down over time. Studied for sleep, but its presence does not guarantee sleepiness.
CBC — CannabichromeneStudied for inflammation-related effects, mainly in laboratory and animal research. Benefits in people remain unproven.
THCV — TetrahydrocannabivarinStudied for blood-sugar regulation. Claims that it reliably suppresses appetite or boosts energy are not established.
CBDV — CannabidivarinStudied for seizures and neurological conditions. A clinical seizure trial did not demonstrate a benefit over placebo.
CBDA — Cannabidiolic AcidThe acidic form of CBD, which converts to CBD when heated. Studied for nausea-related effects in animals.
CBGA — Cannabigerolic AcidA starting compound the plant uses to produce several other cannabinoids. Heating converts it to CBG.
CBCA — Cannabichromenic AcidThe acidic form of CBC. Heating converts it to CBC; its effects in people are not well understood.
THCVA — Tetrahydrocannabivarinic AcidThe acidic form of THCV. Heating converts it to THCV; direct human research is limited.
CBNA — Cannabinolic AcidThe acidic form of CBN. Heating converts it to CBN; its own effects are poorly understood.

These results help you compare products, not predict guaranteed effects. A trace amount on a COA is not equivalent to the doses used in research. The amount consumed, overall formulation, and individual response all matter.

Explore the Terpenes

Terpenes contribute to cannabis’s aroma and flavor. When a terpene panel is available, look at the most abundant terpenes and the total concentration.

TerpeneCommon Aroma
LimoneneCitrus
MyrceneEarthy, herbal
PinenePine
LinaloolFloral, lavender
Beta-caryophyllenePeppery, spicy

Terpene profiles can help you recognize aromas and flavors you enjoy. They do not guarantee a particular experience, and higher percentages do not automatically mean better quality.

Not every COA includes terpene results. A testing method listed on the report does not necessarily mean that test was performed on the sample.

Know the Abbreviations

TermMeaning
NDNot detected by the test; not proof of an absolute zero amount.
NTNot tested on this report.
N/ANot applicable.
LOQLowest amount the lab can reliably measure numerically.
ALAction limit used to assess a contaminant result.
ppmParts per million—a unit for small concentrations.

Why It Matters

Test results help you understand what was actually measured and make more informed comparisons. Match the batch, review the safety categories, and consider the full profile—not just THC. Results describe the sample tested and cannot guarantee that every item is identical or predict exactly how a product will affect you.
