Why CBD Potency Matters
CBD has an incredible array of health benefits. Studies indicate that CBD may provide pain relief, reduce inflammation, and even ease anxiety, depression, and psychosis. Some of these conditions, though may require a strong dose of CBD in order for a person to experience relief, and this is where high-potency CBD oil comes in. You should never start out taking an extra-strong CBD oil if this is your first time trying CBD—start with an average-strength CBD oil (something between 500 and 750 milligrams per 30 milliliter bottle) and play around with the dosage to see what works best for you.
How Do I Determine CBD Oil Strength?
CBD oil products typically vary in strength from mild to extra-strong. When shopping around for the right oil for you, consider the following:
- An average-strength oil will contain a range of 500 to 750 milligrams of CBD per 30 milliliter bottle
- A strong CBD oil will typically contain between 1,000 and 1,500 milligrams per 30 milliliter bottle
- An extra-strength potency would be in the 2,000+ milligrams range of CBD per 30 milliliter bottle
But it’s not just the CBD concentration that makes a tincture strong; there are other factors that you’ll want to keep in mind as well. For instance, the type of hemp extract used to create the product (i.e. full spectrum, broad spectrum, or isolate) may also play a factor in its overall strength.
Full Spectrum vs. Broad Spectrum vs. Isolate
Let’s start with full spectrum CBD oil. This is made with whole plant extract with nothing removed or added, so it’s totally natural. The least manipulated of the CBD oil options, full spectrum maintains a full range of cannabinoids and terpenes, resulting in the desirable entourage effect, in which all of the compounds work together to provide the greatest benefits a CBD oil can provide.
However, full spectrum can have a notable THC content. While full spectrum CBD products will not get you “high” because they contain only trace amounts of the primary psychoactive ingredient within the cannabis plant (less than 0.3%, according to federal regulations), some consumers prefer to eschew the compound altogether.
Broad spectrum implies a greater level of control over the final outcome of the CBD tincture than full spectrum options. While some compounds have been removed, including traceable amounts of THC, broad spectrum products still maintain a broad range of cannabinoids and terpenes to enhance the formula and ensure you receive its benefits.
CBD isolate is what we call pure CBD. That means that solely CBD has been extracted from the plant and no other plant constituents are in the product. The benefit of an isolate is that it contains absolutely zero THC, which is a great option for anyone concerned with passing a drug test. On the other hand, isolate oils may need more overall CBD content to be considered as effective as the whole plant medicine within full and broad spectrum CBD oils.
How Much CBD Oil Is Too Much?
The amount of CBD oil a person needs will depend entirely on the individual, as everyone responds differently. Factors like body weight, metabolism, body chemistry, and the target symptoms will all play a role in the effects felt from CBD.
The best way to determine the right dosage for you is to start small and add more incrementally. Stop at the dosage that gives you relief and makes you feel better. If you experience uncomfortable side effects, lower the dose.
This process is crucial in finding the right CBD oil (and the right potency) for you, and it can help prevent unwanted side effects like nausea, fatigue, and irritability. These adverse reactions are not common, but some people do experience this type of discomfort if they take too much CBD.
If you’re an experienced CBD consumer, you may be comfortable experimenting with high-strength CBD oils. Just keep in mind that CBD may affect certain medications, such as the blood thinner coumadin, so you’ll want to be extra cautious of your CBD dosage if you are on prescription medications. If this is the case, check with your physician before incorporating a strong CBD oil into your daily regimen.
What’s the Best CBD Oil for You?
When choosing the best CBD oil for you, there will likely be some trial and error. Just as it takes some experimentation to discover the perfect dose for your body and symptoms, it can take patience finding the best product for you as well.
There are an overwhelming number of companies within the CBD industry, and while you’re wading through the options, the main thing you want to look for is transparency—specifically in the following categories:
- Third-Party Lab Test Results: To ensure you’re getting a high-quality CBD product, check out the certificate of analysis (CoA). This is a record of independent, third-party testing for each batch of product made. The lab results will indicate the exact cannabinoid composition and the potency of the product, and it will confirm that the oil is free of any unwanted contaminants, like heavy metals or pesticides. The results should also match the information provided by the brand for the particular product, and if a CBD company doesn’t readily publish its CoAs, shop elsewhere.
- Hemp Sourcing: Is the CBD extract being sourced from small family farms or large industrial farms? Brands should be transparent about their plant source, whatever it is. Also keep in mind that American-grown hemp is regulated by domestic laws and will be more dependable than international hemp.
It’s also important to note that while the FDA has not evaluated these CBD products, most studies conclude that CBD is generally safe to consume. Still, it’s always a good idea to check with your physician if you have a serious medical condition or take prescription medications before experimenting with a strong CBD oil.

Accurate determination of cannabinoid concentrations in cannabis and CBD samples is one of the important components of cannabis & CBD testing. ACS determines 20 different cannabinoids and quantifies the level to a specific amount. Our Ultra-High Performance Liquid Chromatographs deliver the highest accuracy that end users can depend on.

TESTING POTENCY BEYOND THC & CBD
Cannabis potency testing measures the cannabinoids present in your cannabis sample and measures the strength of those compounds. ACS Lab uses an Ultra High-Performance Liquid Chromatography (HPLC), which is the preferred instrument for testing cannabis edibles and extracts due to its ability to test samples at room temperature without requiring a catalyst to produce a heat reaction. This method can also test for THC Acid (THCA) and CBD Acid (CBDA), which a gas chromatograph would not.
CONSUMERS ARE DEMANDING MORE INSIGHT
When deciding which cannabis strains best suit your consumer’s needs, it’s vital to consider the cannabinoids present in your products as well as their potency. Cannabinoids are chemical compounds secreted by cannabis flowers that mimic the effects of endocannabinoids, which are naturally produced by the human body. Endocannabinoids interact with the human body’s endocannabinoid system (ECS), which helps us maintain homeostasis . Thus, cannabinoids can be a vital part of human health and determine your product’s therapeutic value.
LOOKING FOR BETTER POTENCY TEST RESULTS?
Cannabinoids occur mostly in the plant resin that’s produced by the structures known as trichomes. Trichomes help protect cannabis from insects, animals, fungi, light contaminators and other environmental attackers. The sticky resin is also rich in terpenes , which are responsible for the plant’s smell, taste and therapeutic effects.
To help influence your plant’s cannabinoid profile, the best method is to select a seed whose genes have the potential to produce the potency you desire. For example, if you live in the mountains, you may select a seed that was specially bred for high-altitude growth. But you may also influence how much resin a plant produces through its micronutrients, temperature exposure, humidity levels, harvest methods and water quality.
Heat, for example, can hinder resin formation, so you may want to keep temperatures as low as possible–especially in the late stages of the plant’s bloom cycle. You also want to pay close attention to trichome color throughout the harvest. When trichomes are clear and translucent, they’re not ready for processing yet. But as you notice the trichomes lose opacity and form an amber hue, you know that the plant has reached optimal levels of cannabinoids.
LEGAL & SCIENTIFIC DRIVERS FOR POTENCY TESTING
As laws continue to change in the U.S., the need for standardized and consistent potency testing is necessary to keep consumers safe from unwanted side effects. For hemp, potency testing is required to prove that it contains less than the maximum limit of THC (0.3%).
Potency testing also allows scientists to research how cannabinoids may work differently based on whether they are contained in flower, oils or topicals. This type of research can enhance the ability to market your product to the targeted customer that could benefit from its effects the most.
It’s also important to understand your product’s potency to meet market demand for high THC or CBD levels. You can also utilize potency results to educate your customers with information they need to determine the proper dose for their specific symptoms. When a product’s cannabinoid profile is transparent and documented, customers can work with their dispensary professional to find the best strain for them.
For example, cannabinoids interact with the body’s ECS by connecting to various endocannabinoid receptors that are present in the brain (known as CB-1 receptors) and throughout the body (CB-2 receptors). Depending on which CB receptor the cannabinoid attaches to, the effects on the body can be significantly different, which can be important if you’re considering a cannabis strain that is needed for pain relief, for instance, as opposed to mood regulation. Cannabis plants can produce anywhere between 80-100 different types of cannabinoids that synergize to make up the therapeutic and cognitive effects of the strain. The two most in-demand cannabinoids are delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), but other compounds such as cannabinol (CBN) are also starting to emerge. Customers understand these compounds at a basic level and expect to see potency levels that match their desired effects.
POTENCY TESTING WITH ACS LABORATORY
At ACS Laboratory, we currently test flower, edibles and extracts for 20 different cannabinoids, which can alleviate symptoms related to several common conditions: mood and behavior disorders, gastrointestinal and neurological ailments, and pain and sleep-related issues, to name a few. Refer to the FAQ section below that explains more about each cannabinoid as well as the importance of potency testing.
FAQS ABOUT POTENCY TESTING
No. The two primary ways in which cannabis potency is tested is either by Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC). Some companies use GC due to its speed of analysis and simplicity in finding common cannabinoids like THC, CBD or cannabinol (CBN). This method imitates the process of heating the cannabis product, so if the product will be smoked, this method can provide insight on the potency of different cannabinoids in this form.
However, because heat is required in this process, acid forms of cannabinoids like THCA or CBDA cannot be identified. This is where HPLC becomes a favorable way to test cannabis potency because it can identify the acid molecules of major cannabinoids before they will convert to their corresponding compounds through the heat of smoking or baking. HPLC instruments use an ultraviolet wavelength detector to identify the cannabinoids, so it is much more inclusive of various forms of cannabinoids in their free form or acidic state. HPLC is often the preferred choice for potency testing.
Two issues that can affect a hemp plant’s cannabinoid profile are the time of year and the terrain in which it’s planted. Other factors include chemical exposure and environmental stress. That is why you may want to start potency testing during the plant’s vegetative state.
Through vegetative potency tests, laboratories like ACS can analyze plants early in their life cycles to identify the CBD and THC potency. This test helps you avoid the time-consuming process of raising up seedlings to maturity and waiting to test the flower after harvest. It helps enable more rapid development that provides patients and consumers with the quality and safety they expect.
Finally, you’ll want to retest your cannabis post-harvest once your product has been manufactured. This will guarantee that the levels match what you expect.
ACS Lab currently tests for the 16 cannabinoids below, plus 4 new ones ( ᐃ8-THCV, ᐃ10-THCV, EXO-THC, CBT)
In our dedicated Florida laboratory we test potency levels of 16 core cannabinoids including THCA-A, CBD, CBDA, CBG, THCV, CBC, CBN, CBGA, Δ9-THC, Δ8-THC, CBDV, CBNA, CBCA, CBDVA, CBL and THCVA.
