Third-Party Lab Analysis
The industry standard for quality assurance...
With a little education on how to read the certificates of analysis, you can be an expert CBD product consumer and know how to tell which products are worth trying! Below we will show you our COAs, how to read them, and give tips on what to look for from anyone selling cannabinoid-infused products.
State-Required Cannabinoid Testing
For compliance with the hemp farming pilot programs adopted by the NCDA as well as most other states across the U.S., farmers are required by law to have these first two COAs completed at specified times. Since Delta-9 Analytical was the NCDA contracted hemp testing lab and USDA licensed as well, we are currently using them for all our 3rd party lab testing.


First COA
For this first COA, hemp farmers are required to notify the NCDA when their plants transition into the flowering stage, meaning when the plants start producing the bud structure that produces cannabinoids like CBD & THC. The NCDA sends out an agent to take trimmings from the top buds of our plants and collect them for 3rd party lab testing. The NCDA contracts out this service to an ISO & DEA certified analytical testing lab called Delta-9 Analytical. They test the buds to ensure that the THC content is at or below the Federal legal limit of .3% and so long as it is, the crop is approved to harvest.

The second state required cannabinoid test is to be conducted on a hemp farmer's flower post-harvest. This is required to be done before the product is either sold or processed into CBD products. So long as the Delta-9 THC level is at or below .3%, the harvest is approved to take to market or be processed for finished CBD goods. As you can see in the COA to the right, our 2020 harvest tested out at .06% Delta-9 THC, well below the Federal legal limit that defines hemp.

How to Identify a Fraudulent COA
Full-Spectrum CBD Distillate
Post-Processing Full Panel COA
At Piedmont Green Dispensary, we firmly believe that full panel COAs for CBD distillate are vital for the health of our clients as well as the future of the cannabis industry in North Carolina!
Full panel COAs contain all the testing required of fully regulated legal cannabis states such as California, Colorado, & Oregon.
Heavy Metals, Microbials, Mycotoxins
Hemp has an uncanny ability to absorb whatever is in the soil it is grown in. Heavy metals, microbials, and mycotoxins (fungus) appear quite frequently, and it is imperative that CBD companies test their distillate for these substances. As you can see on our full panel, our distillate is clean & clear!
Pesticides
All hemp farmers know that the biggest struggle is pest damage. At Piedmont Green Dispensary, we use all organic practices on our farm. Our only pest management is done using natural predators and OMRI listed insecticides.
Although this is the case, we ended up testing out with VERY low levels of 3 pesticides. The COA shows parts per billion just over 300 at the highest. LOQ is the lowest possible level that is detectable and that is at 100 PPB, making this near trace levels. Also, California limits the following pesticides that showed up in our full panel as follows:
- Bifenthrin – CA limit of 500 ppb
- Spirotetramat – CA limit of 13,000 ppb
- Thiamethoxam – CA limit of 4,500 ppb
According to industry standards, our distillate tested out to be free of pesticides.
Residual Solvents
At Piedmont Green Dispensary we utilize a cryo-ethanol extraction process to produce our Full-Spectrum CBD distillate. Cryo-ethanol extraction is the process of soaking hemp flower in super cooled ethanol that pulls the cannabinoids out of the plant matter. Then the CBD free plant matter is filtered and the CBD rich ethanol is put in a rotary evaporator. This pulls out the ethanol and leaves you with a thick, dark CBD oil called Crude CBD Oil. This is then filtered and distilled into full-spectrum CBD distillate. As you can see in our Full Panel COA, our distillate tested out as ND on all solvents meaning Non-Detectable.
Cannabinoid Content
In CBD distillate, the Delta-9 THC level is not limited by the federal nor state government. This is because CBD distillate is the ingredient used to infuse CBD into a support oil and if need be, into another product entirely. It is then the responsibility of the CBD product manufacturer to utilize a 3rd party analytics lab to ensure that the Delta-9 THC level in the finished, labeled CBD product is at or below .3%.
