…and how to read a COA.

Blissables Editorial · 4 min read

Hemp is an unusual category: the front of the package tells you what a product is supposed to contain, but the plant it came from doesn’t come with a guarantee. Cannabinoid content varies. Growing conditions vary. And because hemp plants readily absorb things from their soil, what ends up in the final product isn’t a given. That’s the whole reason third-party lab testing exists — and why it’s worth understanding before you buy anything.

The key word is independent. A third-party lab has no stake in the results — it isn’t the company selling the product. That independence is what makes the testing meaningful. A brand testing its own products and reporting its own grades is a very different thing from an accredited outside lab doing the checking.

The document that lab produces is called a Certificate of Analysis, or COA. It’s the receipt that tells you what’s really inside.

A good COA covers two big questions.

Is the cannabinoid content accurate? This is the potency panel. It confirms how much CBD, THC, and other cannabinoids the product actually contains — so you can check that it matches the label, and confirm the THC level is what you expect. If a label and a COA disagree, trust the COA and question the brand.

Is it free of the things you don’t want? This is where testing earns its keep. A thorough COA screens for:

• Pesticides — residue from cultivation.
• Heavy metals — like lead and arsenic, which hemp can pull up from soil.
• Residual solvents — leftovers from the extraction process.
• Microbials and mycotoxins — mold, bacteria, and related contaminants.

A clean potency number means little if the product also carries contaminants, which is why the full panel matters.

You don’t need a chemistry background. A three-step scan gets you most of the value:

• Check the match. Do the cannabinoid amounts on the COA line up with what the label claims?
• Check the THC. Confirm the Delta-9 THC figure is what you expect — important for both legality and drug-test considerations.
• Check the contaminants. Look for “pass” results (or non-detect) across pesticides, heavy metals, solvents, and microbials.

Also glance at the date and batch number. A COA should correspond to the specific batch you’re holding — an old report for a different batch isn’t telling you about your product.

Lab testing turns “trust us” into “here’s the proof.” An independent COA is the single best tool you have for confirming a hemp product is both accurately labeled and clean — so before you buy, look for one, and take a minute to actually read it. A brand that makes its lab results easy to find is a brand telling you it has nothing to hide.
