How to Read a Cannabis Label (COA)

As cannabis products become more widely available, understanding how to read a cannabis label and the COA on it is essential for making informed purchasing decisions as learning how to read a COA ensures you know exactly what you're consuming. Let's dive into what a COA is, why it's important, and how to read it.

What is a Certificate of Analysis (COA)?

A Certificate of Analysis is an official document provided by a third-party laboratory that tests cannabis for potency, contaminants, and other critical factors. These reports help confirm that a product meets state regulations and quality standards.

Why is a Certificate of Analysis (COA) Important?

• Ensures product safety by checking for harmful substances like pesticides, heavy metals, and mold.
• Confirms potency levels of cannabinoids such as THC and CBD.
• Provides transparency about the product’s composition.
• Helps consumers make informed decisions based on their needs and preferences.

How to Read a Cannabis Label's COA

A COA contains multiple sections with key information about the product. Here's what to look for:

Product Information

• Strain name or product type (e.g., flower, vape, edible)
• Batch number (used to track specific production batches)
• Testing lab details (name and certification number of the testing facility)

Cannabinoid Profile

This section displays the concentration of cannabinoids in the product, usually listed in percentages or milligrams per gram (mg/g). Key cannabinoids include:

• THC (Tetrahydrocannabinol) – The primary psychoactive compound in cannabis.
• CBD (Cannabidiol) – A non-intoxicating compound known for its therapeutic properties.
• CBG, CBN, THCA, CBDA, and other minor cannabinoids – Each with unique potential benefits.

Terpene Profile (if included)

Terpenes contribute to the aroma, flavor, and potential effects of cannabis. Common terpenes include:

• Myrcene – Known for its relaxing properties.
• Limonene – Often associated with an uplifting effect.
• Pinene – May help with focus and mental clarity.

Contaminant Testing

This section verifies that the product is free from harmful substances. Common tests include:

• Pesticides – Ensures the product is free from harmful agricultural chemicals.
• Heavy Metals – Tests for lead, mercury, arsenic, and cadmium.
• Residual Solvents – Important for cannabis extracts to confirm safe processing methods.
• Microbial Contaminants – Screens for mold, bacteria, and other pathogens.

Moisture Content & Water Activity (For Flower)

• Moisture content affects product freshness and combustion quality.
• Water activity ensures the product is stored properly to prevent mold growth.

Tips for Reading a COA Accurately

Understanding a COA can seem overwhelming at first, but focusing on a few key elements can make it easier. These tips will help you verify the authenticity and reliability of the lab report:

• Always ensure the COA matches the batch number on your product’s packaging.
• Look for the testing lab’s certification to verify legitimacy.
• Pay attention to the date of testing to ensure freshness and accuracy.
• Be cautious of incomplete or missing information, which may indicate low-quality testing or non-compliance.
