CBD Product Safety Frequently Asked Questions

CBD Product Safety and CBD Product Transparency are foundational pillars of what we’re about at Fringe. Unfortunately, that isn’t always the case for other products in the market. Here are some things to keep in mind.


CBD is considered to be a very safe product. In November 2017, the World Health Organization (WHO) declared that CBD in humans exhibits no evidence for abuse or dependence potential, and that there is no evidence of public health related problems associated with the use of pure CBD.

CBD is also not addictive and does not cause withdrawal symptoms, even at very high doses up to 750mg. Adverse events are minimal, even at doses of several hundred milligrams per day. The most common adverse events at high doses are decreased appetite, diarrhea, and sleepiness.



To ensure you are taking a well manufactured CBD product, make sure that there is a QR code on your product linking it to a Certificate of Analysis (COA). This COA lab report confirms the safety of the product. You should see that the product has been tested for heavy metals, pesticides, microbials, and residual solvents.


Fringe products are produced from organically farmed, US grown, non-GMO Hemp. They are tested for potency, purity, heavy metals, microbials, residual solvents, and pesticides at 3 different stages during production. In an unregulated industry, such as the CBD market it is imperative that the test of each batch of product be transparent to both the healthcare professional and their patient/client. 

You will see a QR code on all of our packages, where you can find out more information about the steps Fringe is taking to be a leader in the CBD health and wellness community.  We care about where our products are made, what they are made with, and who makes them. 



Currently CBD products on the market are not regulated by the FDA. Third party testing is important because these labs are independent of the company making the products. As such, the analysis is unaffected and unbiased by financial interests.

From a collective summary of 2020 consumer reports, the largest deterrents preventing people from trying CBD included a lack of trust in the manufacturers and a lack of understanding of the benefits. We don’t blame them. The CBD industry is confusing. 

The majority (~70%) of CBD products in the market do not contain what their labels say they do. Yikes. 

Steps to improve trust in your CBD products:

1.    The CBD product must have a QR Code. There is simply no other way (today) that a CBD company can verify what they are selling you. 

2.    Verify what IS in the CBD product. Look for active milligrams of CBD in a serving and in the total product. 

3.    Verify what ISN’T in the CBD product. A QR Code on the package should link you to a document that verifies that the CBD you have purchased does not contain heavy metals, pesticides, microbial contamination, or any harmful chemicals. 

A Certificate of Analysis (COA) is a document that displays the results of an analysis of the chemical composition of a product. A COA will present the cannabinoid composition of the product as well as other cannabis derived compounds such as terpenes.

A comprehensive COA will also look for things that you don’t want in a product, including microbes (such as salmonella and e.coli), heavy metals, pesticides, and solvents. The COA will provide you with details about the composition of broad and full spectrum products and will help you to ensure that the product is safe for consumption.

Some companies do not present a COA at all, while others only provide COA’s for cannabinoid and terpene composition. Be sure to look for a COA that includes testing for contaminants. Because hemp is a “remediation” crop, it has the ability to extract heavy metals and pollutants from the soil. This is great for cleaning the soil, but these are not things that you want to put into your body.

COA’s should be created for every batch of product that is produced, as well as for every end product. Your product should have a QR code on it that is linked to a COA.


Fringe water soluble CBD powder is made in five steps.

First, the hemp plant is cultivated, and the leaves and flowers are harvested and dried. The leaves and flowers are the parts of the hemp plant that contain the highest concentrations of cannabinoids. The hemp used to make Fringe products is certified organic and non-GMO.

Second, the leaves and flowers are ground up with a solvent into a biomass. The solvent pulls the cannabinoids, terpenes, and flavonoids from the biomass and separates them from unwanted material like fiber.

Third, the solvent extract goes through the process of “winterization,” which further purifies it and leaves an oil residue, and the solvent is recovered.

Fourth, the oil residue is distilled to separate the compounds in the oil, based on their boiling points.

Finally, the product is processed into a water-soluble powder by creating oil particles that are surrounded by a starch/soluble fiber. 

Fringe makes both a CBD isolate (containing only CBD) and a broad-spectrum CBD (containing CBD and additional plant compounds like CBG, CBDV, and CBN).

Testing for potency and contamination takes place at three points: (1) on the biomass, (2) prior to distillation, and (3) after the final product is manufactured.



Fringe products are produced from organically farmed, USA grown, non-GMO hemp.  Fringe sources hemp from farms in CO, WA and OR.


No. Drug tests measure a metabolite of THC in the urine.

However, a recent study found that many CBD products on the market are contaminated with THC. This makes it very important to look at the COA of a product to ensure that THC is being tested for, and that it is undetectable. Full spectrum CBD products may contain small amounts (less than 0.3%) of THC, but this is so low that it should not show up on a drug test, although again, it is important to ensure THC levels are below 0.3% by reviewing a COA.



It is advisable to consult with a knowledgeable health care provider who has experience using CBD before starting a supplementation routine.


Due to federal regulations, we are not able to comment on drug interactions. We recommend you speak with your healthcare provider.


Adverse events or side effects are minimal, even at doses of several hundred milligrams per day. The most common adverse events at high doses are decreased appetite, diarrhea, and sleepiness.
