Maybe you’ve been considering taking cannabidiol (CBD), to see if it eases symptoms of chronic pain, anxiety, or another condition. But reading and understanding CBD product labels can be overwhelming, especially if you’re new to CBD.
Instead, it’s up to you, the consumer, to do your research or rely on third-party testing to determine if a CBD product is legit and what’s in it.
So, here’s a 101 guide to CBD labeling to help you understand what you’re getting.
First, you need a rundown on cannabis vocabulary.
CBD vs. THC
Hemp vs. marijuana
Depending on where you live and the laws in your state or country, you may be able to buy both marijuana-derived and hemp-derived CBD products. Or you may have access to hemp-derived CBD products only — or no access to CBD products at all.
Knowing the difference between marijuana and hemp is important because marijuana-derived CBD products may cause some psychoactive effects, and the THC included in these products will show up on a drug test.
It’s important to keep in mind that CBD and THC are known to work better together than they do alone. This is known as the entourage effect.
- Full-spectrum CBD contains all of the naturally available compounds of the cannabis plant, including THC. However, in hemp-derived full-spectrum CBD, the THC will be no more than 0.3 percent.
- Broad-spectrum CBD has all of the naturally occurring compounds, except THC.
- CBD isolate is the purest form of CBD, isolated from the other compounds of the cannabis plant. CBD isolate should have no THC.
So, which should you choose? Some people prefer full-spectrum because they want the whole kit-and-caboodle of the cannabis plant’s benefits — with all the cannabinoids and other compounds working in synergy.
Others choose broad-spectrum because they want all the terpenes and flavonoids but no THC. Some people prefer CBD isolate because it’s tasteless and odorless, and they don’t want any other compounds included.
Cannabinoids, terpenes, and flavonoids
Now, about those compounds. What are they exactly? In addition to CBD and THC, the cannabis plant contains more than 100 cannabinoids, plus a whole bunch of other compounds called terpenes and flavonoids.
Cannabinoids go to work on your body’s endocannabinoid system. The endocannabinoid system helps keep the nervous system and immune function on an even keel.
Like cannabinoids, terpenes are another plant compound reported to have therapeutic and health-boosting benefits. And flavonoids, compounds also found in green tea and certain fruits, have been shown to protect against disease.
Once you’ve made a decision about the type of product you’re looking for, you’ll want to check the ingredient label of the product in question.
Make sure the product actually has CBD or cannabidiol in it so that you’re not wasting your money. Keep in mind that some products will list CBD as hemp extract, which is a result of the ever-changing laws and regulations.
Look at the ingredient list closely to make sure you aren’t allergic to anything.
If you’re buying a 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 hempseed oil.
If you’re buying a full-spectrum product, check the THC percentage to be sure it meets your needs.
If you’re buying a broad- or full-spectrum product, it may also list the cannabinoids and terpenes included, though these are often included in the certificate of analysis (COA), which we’ll tell you more about in the next section.
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. It might look like a bunch of gobbledygook at first, but you’re looking for a few key factors:
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.
If your product is full- or broad-spectrum, look for a list of cannabinoids and other compounds. Cannabinoids like cannabidiolic acid (CBDA), cannabinol (CBN), cannabigerol (CBG), and cannabichromene (CBC) should be on the list.
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.”
A lot of confusion can come into play when you’re trying to determine the amount of CBD in a product and how much you’re getting with a serving.
A number that’s often in larger print typically lists the amount of CBD in milligrams for the entire product, not the serving size or dose.
If you’re wondering where to buy reputable CBD products, you have several options. You can find oils, topicals, and edibles online, direct from many retailers.
If you have a trusted compounding pharmacy that stocks CBD, that’s also a smart place to get a suggestion for a product suited to your needs. Your physician may even have a recommendation.
CBD is generally reported as safe, with the most common side effects listed as:
- changes in appetite
- changes in weight
If you’re considering using CBD, however, it’s a good idea to talk to your doctor first. CBD may interact with certain over-the-counter drugs, dietary supplements, and prescription medications — especially those that contain a grapefruit warning.
For the same reasons that CBD could cause medication interactions, it could also cause liver toxicity or injury, a recent study shows. However, this study was conducted on mice, and researchers say you’d have to be taking extremely high doses for this to be a concern.
Now that you’re armed with the tools to decipher CBD labeling, you can shop for products with confidence and find one that’s right for you.
Remember, if a CBD retailer is making bold claims about what the product can do or if it doesn’t have third-party testing, the product probably isn’t worth buying. Always start with a small dose of a new product first to see how you respond before trying more.
Is CBD Legal? Hemp-derived CBD products (with less than 0.3 percent THC) are legal on the federal level, but are still illegal under some state laws. Marijuana-derived CBD products are illegal on the federal level, but are legal under some state laws. Check your state’s laws and those of anywhere you travel. Keep in mind that nonprescription CBD products are not FDA-approved, and may be inaccurately labeled.
