Why Lab Testing Matters for Cannabis Products

When it comes to cannabis products, quality matters. Third-party lab testing — and the resulting Certificates of Analysis (COAs) — are your best tools for ensuring the products you consume are safe, pure, and accurately labeled.

What Is a Certificate of Analysis?

A COA is a document from an independent laboratory that verifies the contents of a cannabis product. It tests for cannabinoid potency (how much THC, CBD, etc.), terpene profiles, and the absence of harmful contaminants.

What Labs Test For

Potency: Confirms that THC and CBD levels match what is on the label. This ensures you get the experience you expect and the dosing you planned for.

Pesticides: Tests for harmful chemical residues that can accumulate during cultivation.

Heavy Metals: Cannabis plants can absorb lead, mercury, arsenic, and cadmium from contaminated soil.

Residual Solvents: Especially important for concentrates and extracts, this ensures no harmful chemicals remain from the extraction process.

Microbials: Tests for mold, bacteria, and other pathogens that could pose health risks.

Red Flags to Watch For

• No COA available or company refuses to share lab results
• Lab results from the company itself rather than an independent third party
• Outdated test results (look for recent batch-specific testing)
• Potency claims that seem too good to be true
