After the CBD extraction, these Isolates, Full or Broad Spectrum components will be either continue into a production line into final products or sold to a different manufacturer who will add them to other substances to create various CBD products like teas, gummies, capsules, edibles, tinctures, topical creams, or salves.
Label CBD Terminology: 
If you’re buying, for example, CBD oil, the product will likely include a carrier oil to stabilize and preserve the CBD and help your body absorb it. That’s why one of the main ingredients of the product may be grapeseed oil, MCT oil, olive oil, or even cold-pressed hemp seed oil.
A CBD oil or an edible might also contain a natural or artificial flavoring or coloring.
If you’re buying a full-spectrum product, check the THC percentage to be sure it meets your needs.
If you’re buying abroad- or full-spectrum products, it may also list the cannabinoids and terpenes included, though these are often included in the certificate of analysis (COA).
Certificate of Analysis:
A reputable CBD product will come with a COA. That means it’s been third-party tested by an outside laboratory that doesn’t have a stake in the product.
You may be able to access the COA while you shop by scanning the QR code on the product with your smartphone.
Many product websites or retailers also have the COA available. If it’s not, email the company and ask to see the COA. The factors to look for would be:
1. Labeling accuracy
The CBD and THC concentrations on the COA should match what’s stated on the product label. Labeling inaccuracies are a common issue with CBD products.
One study revealed that only about 31 percent of products are accurately labeled. After analyzing 84 CBD products sold online, researchers found that with respect to CBD, about 43 percent have a higher concentration than stated, and about 26 percent have less than claimed.
2. Cannabinoid profile
If your product is full- or broad-spectrum, look for a list of cannabinoids and other compounds. Cannabinoids like cannabidiol acid (CBDA), cannabinol (CBN), cannabigerol (CBG), and cannabichromene (CBC) should be on the list.
3. Additional lab charts
Look for heavy-metal and pesticide analyses, as well. You can determine if a certain contaminate is detected at all, and, if so, if it’s within a safe limit for ingestion. Check the status column of these charts and make sure it says “pass.”
