What is a Certificate of Analysis?
A Certificate of Analysis (COA), is a document from a laboratory that shows the number of various cannabinoids in a CBD product. Manufacturers are encouraged to send every batch of every product they make to a lab to complete testing. This ensures their customers are protected and that their products have the amount of CBD that they advertise.
Not all companies openly share their COAs. In that case, it is best to reach out to the company and request it before purchasing any products from them. If you are unable to obtain a COA from the manufacturer’s website, customer service, or the product label itself, you should avoid purchasing from them. Quality companies will always have their CBD products lab tested, and COAs available. After all, the purpose of COAs is for both the manufacturer and customer to double-check the quality of their work.
Why are Certificates of Analysis Necessary?
With so many CBD products on the market, it can be difficult to determine whether a product is good or bad. It’s easy for companies to print claims on their labels without anything to back it up or proof that the claims are true.
This can cause numerous problems. For one, customers can be paying more for a product that is not what it claims to be. Also, customers can be deceived about the quality and composition of the product they are purchasing.
Enter Certificate of Analysis. COAs are a must-have for reliable, law-abiding CBD manufacturers. They provide the true composition for each product so that customers can make informed decisions about the products they choose to purchase.
How to Read a COA
COAs are not always simple to read and you will find that they can come in a variety of formats.
Commonly, you’ll see COAs that show results in one of the following three ways:
- Milligrams (mg) of CBD in the full product
- Milligrams (mg) of CBD per gram (g)
- Milligrams (mg) of CBD per milliliter (ml)
Please note that CBD is used in this example, but the same goes for all of the other cannabinoids in the COA.
If the COA shows the first type of result, milligrams (mg) of CBD in the full product, then you don’t need to worry about doing any calculations. This result already shows the total amount of cannabinoids in the product.
If your results read like the last two examples, then you will need to make calculations. As a refresher, a milliliter (ml) is a measurement of volume and grams (g) is a weight. So, even though most CBD products will show the size in ounces (oz) you can convert that number into milliliters. Remember, 1oz will always equal 30ml. Keep in mind, two 30ml tinctures will not weigh the same in grams, as the weight (g) is affected by each ingredient in the product’s formulation.
Again, understanding COAs is crucial when determining which company to purchase CBD from. As a general rule of thumb, if a company doesn’t offer any of their lab results or COAs, you may want to skip out on purchasing from them.
