A cannabis COA ensures product quality, potency, and safety. Understanding it is key to making informed purchases, whether you’re new or experienced.
The cannabis industry has experienced transformative growth in recent years, with legalization sweeping across many parts of the globe.
In the United States alone, cannabis is legal for medical use in 38 states and for recreational use in 23 states as of 2024. The market’s expansion, valued at over $33 billion, underscores the growing consumer demand and business opportunities.
However, with increased legalization comes a stronger emphasis on safety, transparency, and regulatory compliance. For both consumers and sellers, understanding these requirements is crucial.
One of the most essential tools in this process is the Certificate of Analysis (COA).
COAs are more than just paperwork—they ensure product quality, confirm regulatory compliance, and protect consumers from harmful substances.
In this article, we’ll dive into what a COA is, how to interpret it, and the critical elements specific to cannabis products.
What Is a COA?
COA stands for Certificate of Analysis, a document provided by an accredited third-party laboratory after testing a cannabis product.
It outlines key information about the product’s chemical composition and safety, confirming that it meets industry standards.
For cannabis and THCA products, it verifies:
- Potency: Levels of cannabinoids like THC, THCA, and minor cannabinoids.
- Purity: Tests for contaminants, including pesticides, heavy metals, and microbial impurities.
- Terpenes: Information on aromatic compounds that influence the flavor and effects (when available).
COAs ensure transparency and demonstrate that the product meets legal and quality standards, providing peace of mind to consumers.
Why Is a COA Important?
- Consumer Confidence: Assures buyers that the product is free from harmful contaminants and matches its advertised potency.
- Product Potency: They help verify if the cannabinoid levels match what’s advertised.
- Regulatory Compliance: Demonstrates adherence to local and federal safety standards.
- Transparency: Builds trust between manufacturers and consumers by verifying product claims.
Reliable COAs include detailed information about the lab that conducted the analysis, product batch numbers, and specific test results. These details confirm a COA’s authenticity, which we’ll explore in the next section.
How to Read a COA: Main Elements
The main elements a COA must include are:
- Name of the Laboratory
- Lab Location
- Sample Test Date
- Product Type
- Batch Number
A COA might seem overwhelming at first, but understanding it can be straightforward with a little guidance. Here are 3 key sections:
1. Cannabinoid Profile: This section lists the concentrations of cannabinoids in the product.
2. Terpene Profile: Terpenes aren’t always included in COAs, but if they are, this section highlights aromatic compounds like limonene and myrcene, which influence flavor and effects.
3. Contaminant Testing: Check this section to verify that the product is free from harmful ingredients.
Quick Tips for Evaluating COAs
- Verify Lab Credentials: Ensure the lab is ISO-certified for cannabis testing.
- Match Product Names: Double-check that the COA corresponds to the exact product in question.
- Look at Dates: The test date should be recent to reflect current product conditions.
What Must a Cannabis/THCA COA Contain?
A COA for cannabis and THCA products goes beyond the basics, offering detailed insights into the product’s composition and safety. Key elements include:
1. Cannabinoid Profile
This section lists the concentrations of cannabinoids in the product. Look for:
- THCA Content: Ensure the THCA percentage matches the label claims.
- THC Levels: Confirm it’s within the legal limit (below 0.3% for hemp-derived products).
- Minor Cannabinoids: These include CBG, CBN, and CBC, which can enhance the entourage effect.
2. Terpene Profile
Terpenes aren’t always included in COAs, but if they are, this section highlights aromatic compounds like limonene and myrcene, which influence flavor and effects.
3. Contaminant Testing
Check this section to verify that the product is free from:
- Heavy Metals: Lead, mercury, cadmium, etc.
- Pesticides: Harmful agricultural chemicals.
- Microbials: Molds, bacteria, or yeast that can affect safety.
4. Batch Information and Lab Details
Ensure the COA includes:
- Batch Number: It should match the product label.
- Testing Date: Recent testing is a sign of freshness.
- Laboratory Information: A third-party lab with accreditation ensures impartiality.
5. Moisture Content and Water Activity
- Measures water levels to ensure product freshness and prevent microbial growth.
6. Foreign Material Analysis
- Ensures no extraneous materials, such as hair or dirt, are present in the product.
7. Important Technical Terms in a COA
To understand a COA, familiarize yourself with these common abbreviations:
- LOQ (Limit of Quantification): The lowest concentration of a compound detectable with precision.
- LOD (Limit of Detection): The smallest amount of a substance that can be identified.
- ND (Not Detected): Indicates that the compound was not found in the sample.
- NT (Not Tested): Means the particular test was not conducted.
FAQs
How can I obtain a COA if I sell cannabis products?
Most third-party testing labs provide COAs upon request after analyzing your product.
Is a COA for hemp products different from cannabis or THCA products?
Yes, the testing parameters in a COA for cannabis may differ, especially for THC limits.
Can I trust a COA provided by the manufacturer?
Yes, but verify the lab’s credentials to ensure accuracy and reliability.
What does “Fail” mean in a contaminant screening?
It indicates the product does not meet safety standards for that specific test.
How often should products be tested?
Ideally, products should be tested for every new batch to ensure consistency and quality.
Are COAs required by law?
In most regulated markets, COAs are mandatory for cannabis and hemp products.
Do COAs include terpenes?
Not always, but they’re increasingly becoming a standard feature for premium products.
