Reading a lab report for THC chocolate

Start with the identity at the top

Match the material and batch before reading the big number. A report for cannabis extract is not automatically a report for a finished chocolate containing that extract. The product name, submitted material, batch or lot and report date tell you what was tested. A familiar brand logo on the PDF cannot do that work on its own.

California DCC says laboratories report batch results on a certificate of analysis, or COA, including whether the batch passes or fails each tested substance. Its testing page covers cannabinoids and terpenes alongside contaminant categories. This is a California regulatory example, not a description of every certificate sold with an online product.

Begin with the package beside the report. If its lot number does not match, ask for the corresponding document. If the report names an ingredient rather than a finished bar, ask what evidence connects the ingredient result to the packaged chocolate. Those are basic identity questions; they come before interpreting a percentage.

Does this report actually belong to this finished chocolate?

Percentage, mg/g and mg per serving

A mass percentage and milligrams per gram describe concentration. A stated number of milligrams per serving describes an amount attached to a portion. They can be related only when the relevant weights and material are known. The unit should stay beside every copied figure.

NIST defines milli as one thousandth. From that unit definition, 1% by mass corresponds to 10 mg per gram. This is a unit conversion, not a claim that a particular chocolate has that concentration or that the reported sample represents every bite. NIST: metric prefixes

For a hypothetical finished chocolate reported at 2 mg THC per gram, a stated 5 g portion corresponds arithmetically to 10 mg THC. If the result actually describes the extract used to make the chocolate, that calculation would apply to the wrong material. If the serving weight is unknown, the concentration alone does not supply it. Reading chocolate serving information explains why the portion is a separate input.

Read the notes beneath the results

Not detected does not mean a laboratory proved absolute zero. A report's detection and quantitation limits describe what its method can detect or reliably measure under the stated conditions. Read the legend rather than treating every ND or less-than symbol as a numerical zero.

Look for the names of the cannabinoid columns as well. A report may distinguish THC, an acid form and a calculated total. Do not add a total column to its component columns as if they were separate ingredients. If the report's definitions are unclear, ask the laboratory or maker to explain how that particular result is calculated.

Dates also need their labels. Sampling, receipt, analysis and report issue can occur on different days. A recent issue date does not by itself show that the chocolate was recently manufactured. The package's date and identifier still matter when you connect a document to a particular bar.

Cannabinoid content is one part of testing

A potency panel describes the cannabinoids measured. It should not silently become evidence that the same sample was tested for every contaminant, food allergen or possible adulterant. Look for the actual panels included, the methods and the results relevant to the claim being made.

A pass statement also needs its context. It describes the applicable criteria for the reported tests. It is not a clinical finding about how a person will feel, an allergy clearance or a promise that any amount is suitable. A document can be useful without answering questions it was never designed to test.

This distinction helps when a website places a lab-tested badge beside a broad wellness claim. The report may substantiate a composition statement while supplying no human-outcome evidence at all. Read the laboratory question separately from any claim about sleep, relaxation or a predictable experience.

What to do when the numbers disagree

Kiva's inspected Milk Chocolate page states cannabinoid amounts and warns that ingredients and potency can vary by state. It also presents two different serving-weight entries. That makes the current local package and its matching report important; it is not a reason to blend the website's entries into a new invented serving weight. Kiva: Milk Chocolate product information

For a hypothetical mismatch, write it plainly: this wrapper states one amount per piece; this report shows a different unit or identifies another batch. Send photographs of both. A retailer or maker can then resolve the exact discrepancy. Until the connection is clear, a confident-looking PDF is still a document about an incompletely identified sample.

It is also reasonable to ask for the complete report rather than a cropped screenshot of the potency row. The omitted page may contain the sample description, result legend, test status or laboratory notes needed to interpret that row. Readable context is more useful than an enlarged number detached from its definitions.
