If you’ve ever purchased hemp or cannabis products, you might have come across the term COA. While it might seem like just another industry jargon alongside terms like CBD or terpene, a COA (Certificate of Analysis) is actually a crucial component.
Grasping what a COA represents is essential when buying hemp or cannabis products. While visual and olfactory cues can provide some insights, a COA offers a detailed and comprehensive analysis of the product, helping shoppers make more informed decisions before making a purchase.
What does COA Stand For?
COA is short for Certificate of Analysis. They are the third-party testing results of a laboratory licensed to test for a variety of things. These items can be required by state or federal law (depending on if the product is derived from hemp or marijuana).
What Information Does a COA Contain?
A Certificate of Analysis (COA) provides valuable information for both industry professionals and consumers.
Typically, third-party laboratories test for several key factors, including:
- Cannabinoid potency: The concentration of various cannabinoids.
- Terpene profile: The types and amounts of terpenes present.
- Contaminants: Presence of mold, pesticides, herbicides, or heavy metals.
- Moisture content: Particularly important for smokable flower products.
For hemp products, COAs are mandated by federal law to ensure they adhere to safety standards and contain less than 0.3% Delta 9 THC by dry weight.
For cannabis products, legal marijuana programs vary state by state. However, COAs are a common element among all of them. This testing is a quality control measure to help ensure brands are adhering to all safety standards outlined by the individual state program.
How to Find a COA
There are several ways to access a Certificate of Analysis (COA), and reputable brands ensure that these documents are readily available for their customers.
The first method is to visit the brand’s website. Trustworthy brands typically upload their COAs directly to their site, making it easy for customers to find and verify product information. Keeping these documents up-to-date on the website not only benefits the brand but also provides a convenient resource for shoppers.
Another increasingly popular method involves QR codes. Many brands now include QR codes on their product packaging or labels. Scanning these codes with a smartphone can quickly direct customers to the COA on the brand’s website. This feature enhances convenience, transparency, and accessibility for both customers and brands.
Additionally, you can request a COA by asking an employee at the store where you are shopping. Retailers that sell these products usually keep copies of COAs on hand. A polite inquiry should provide you with the information you need.
Red Flags to Watch Out For
When evaluating COAs (Certificates of Analysis), there are a few key red flags to be aware of. First, check the COA’s expiration date. Typically, COAs are valid for around a year, during which time a product might change and need retesting. This date also helps gauge the age of the product.
Another important indicator is how a brand responds to requests for a COA. If a brand refuses to provide a COA, claiming it is proprietary information, this is a red flag. A refusal to share a COA can erode trust and raise concerns about the transparency and integrity of the brand.
The Bottom Line
A Certificate of Analysis (COA) is an essential resource for both brands and consumers. Although it might appear to be just a document, a COA provides comprehensive information. It allows shoppers to verify potency, quality, and the specific cannabinoid and terpene profiles of a product.
Understanding how to read a COA is crucial when selecting hemp or legal cannabis products. Think of a COA as a treasure map—it guides you to the product that best meets your needs and ensures you make an informed choice.
