Understanding Cannabis Labels: How to Read a COA

As cannabis products become more widely available, knowing how to interpret a product label is key to making confident choices. A Certificate of Analysis (COA) is an essential document that provides details about a product’s potency, purity, and overall safety. Whether you’re a medical patient or a recreational consumer, understanding a COA ensures you’re selecting a product that meets high-quality standards.

What is a Certificate of Analysis (COA)?

A COA is a third-party lab report that verifies the chemical composition of a cannabis product. It confirms cannabinoid potency, terpene content, and the absence of harmful substances, ensuring the product adheres to regulatory standards.

Why is a Certificate of Analysis (COA) Important?

• Verifies the product is free from harmful contaminants like pesticides and heavy metals.
• Confirms accurate cannabinoid levels, so you know exactly what you’re consuming.
• Increases transparency and helps consumers make informed decisions.
• Ensures compliance with industry regulations for consumer safety.

How to Read the COA on a Cannabis Label

A COA is broken down into key sections that provide detailed product information. Here’s what to look for:

Product Details

• Strain name or product type (e.g., concentrate, flower, edible)
• Batch or lot number for traceability
• Testing laboratory information, including certification details

Cannabinoid Potency

This section highlights the percentages or milligrams per gram (mg/g) of various cannabinoids, including:

• THC (Tetrahydrocannabinol) – The main psychoactive component in cannabis.
• CBD (Cannabidiol) – Known for its calming and therapeutic properties.
• Additional cannabinoids like CBG, CBN, and THCA that contribute to the entourage effect.

Terpene Profile (If Available)

Terpenes are natural compounds that influence the scent, taste, and effects of cannabis. Common terpenes include:

• Myrcene – May provide calming effects.
• Limonene – Often associated with an uplifting experience.
• Pinene – Linked to alertness and mental clarity.

Contaminant Screening

This section ensures the product is safe by testing for:

• Pesticides – Confirms the absence of harmful agricultural chemicals.
• Heavy Metals – Checks for lead, mercury, arsenic, and cadmium.
• Residual Solvents – Ensures clean processing, particularly for extracts.
• Microbial Contaminants – Screens for mold, bacteria, and yeast.

Moisture and Water Activity (For Flower)

• Moisture content impacts freshness and smooth combustion.
• Water activity measures storage safety to prevent mold and degradation.

Helpful Tips for Understanding a COA

Interpreting lab reports may feel overwhelming, but these simple guidelines can help:

• Ensure the batch number on the COA matches the packaging.
• Verify that the testing lab is certified and reputable.
• Check the testing date to confirm product freshness.
• Watch for any missing or inconsistent data, which may indicate unreliable testing.

Final Thoughts

Knowing how to read a COA helps you make informed cannabis purchases, ensuring safety, potency, and quality. Whether reviewing cannabinoid content or checking for contaminants, understanding lab reports empowers you to select the best product for your needs.
