How to Read a Certificate of Analysis (COA)

A Certificate of Analysis (COA) is a third-party lab report that certifies the cannabinoid and contaminant profile of a cannabis product. Every reputable brand makes COAs available. Here is what to look for:

THC percentage or milligrams: The stated potency of the product. For flower, this is usually expressed as a percentage of dry weight (e.g., 22% THC). For edibles and tinctures, it is expressed in milligrams per serving.

Total THC vs. THCA: Raw cannabis flower contains THCA (tetrahydrocannabinolic acid), which converts to THC when heated. A COA may list both. Total THC = THC + (THCA × 0.877) gives you the active potency after decarboxylation.

Contaminant panel: A complete COA also screens for pesticides, residual solvents, heavy metals, and microbial contamination. Passing all panels means the product is safe to consume.

Batch number and date: Verify the COA corresponds to the actual batch you are purchasing. Outdated COAs from a different batch are not meaningful for the product in your hand.

THC Potency in the DC, Maryland & Virginia Cannabis Market

The DMV cannabis market spans three distinct regulatory environments, and product potency standards vary across them. In Washington DC, cannabis products sold through gifting-model operations vary widely — quality ranges from budget to premium, and lab testing practices are inconsistent. Bud Lords sources only from verified, lab-tested suppliers.

In Maryland, adult-use retail launched in 2023 with state-mandated testing requirements. Every product sold in a licensed dispensary must carry a COA from an accredited lab. Maryland consumers benefit from the most standardized testing environment in the DMV.

In Virginia, adult-use retail is now fully operational. Licensed retailers are required to carry tested products. Potency labeling is mandatory on retail packaging, making it easier for consumers to compare products side-by-side.

Practical Dosing Guidance Based on THC Percentage

Knowing the THC percentage helps you calibrate your dose. These are general ranges for flower:

Under 15% THC: Mild potency. Suitable for new consumers, microdosers, or anyone who prefers a subtle effect. Often higher in CBD or minor cannabinoids.

15–22% THC: Moderate potency. The most common range for quality flower. Good balance of effect and control for experienced consumers.

22–30%+ THC: High potency. Experienced consumers seeking strong effects. Approach edibles and concentrates in this range with extra caution — the onset and intensity are significantly greater.

Concentrates (wax, shatter, live rosin, diamonds): Typically 60–90% THC. Even experienced consumers start with very small portions — a rice-grain-sized dab is a meaningful dose.

Frequently Asked Questions About THC Testing

Is the THC percentage on a cannabis product label always accurate?

Not always. Studies have found that retail cannabis labels can overstate THC content, sometimes significantly. Gas chromatography and HPLC are the most accurate methods — but accuracy also depends on sample preparation and lab quality. Ask for the COA and verify the lab is accredited.

Can I test cannabis THC at home?

Home test kits exist and can provide a rough indication of THC presence, but they are not accurate for measuring precise percentages. Colorimetric tests confirm cannabinoids are present but cannot quantify them reliably. Near-infrared (NIR) handheld devices offer better accuracy but cost hundreds of dollars.

Why does high THC percentage not always mean a better experience?

The entourage effect means that terpenes and minor cannabinoids significantly influence how THC feels. A 28% THC strain with poor terpene content can feel flatter than a 20% strain rich in myrcene, linalool, and caryophyllene. THC percentage is one data point — not the whole picture.
