What is a COA for CBD and How Do I Read It?

Wondering, “what is a COA?” Or don’t know the best way to approach reading one? We’ve got you covered. 

Firstly, Certificates of Analysis, or COAs, are a big topic here at Premium CBD. We emphasize the importance of checking the COA on every CBD product. That’s how you can confirm the product has met the specifications on its label. 

However, encouraging our readers to look at the COA on their product isn’t enough to ensure safety. COAs can be confusing to look at and it’s not always clear what the words on the page mean. Plus, what is a COA going to help with if you don’t know how to read it? 

We’ll break how to read a COA for CBD so you can get straight to the facts. 

Where to find the COA on CBD products

First of all, you can find the COA on a CBD product in a few different ways. It varies depending on the brand and state you’re in. 

In some states, CBD products are only legal to sell if they have a QR code. You can scan the codes to pull up the COA from a third-party laboratory. Therefore, this means consumers can scan the code and have all of the information at their fingertips. 

While QR codes may be a requirement in additional states in the future, they’re not currently the norm. Instead, consumers have to look at the product’s website or request a copy from the manufacturer. 

Before you buy CBD, you should always check the COA. If you can’t find one, or the manufacturer is not responsive to a request, choose a different product. 

Terms you’ll find on a COA  

Once you’ve located the COA, it’s time to read what it says. Now, don’t worry if you don’t know how to read a COA for CBD yet. COAs have a lot of information in one spot and it can be overwhelming at first. 

First, let’s look at the terms you’ll see on a COA:

Cannabinoids

First of all, get used to the word “cannabinoids.” You’ll be seeing it a lot. CBD is a cannabinoid. There may be many or few cannabinoids present in your product. This depends on if it’s full-spectrum, broad-spectrum or CBD isolate. 

Small amounts of THC can be present in CBD products. However, the COA will confirm that there is no more than the legal amount of 0.3% THC present. It will also confirm that the amount of CBD in the product is accurate. 

Additionally, you may notice other cannabinoids listed on your COA such as CBN and CBG. These occur naturally in the plant and are non-intoxicating. 

Pesticides

Pesticides are sometimes used to keep plants free of pests. However, they don’t just rinse off of the plants after they’ve taken care of the problem. Hemp tends to absorb pesticides. 

Along with that, pesticides directly applied to the surface will absorb into the plant. If there are pesticides in the soil, they will absorb through the plants’ roots. Then they will make their way into the final product. Even if farmers don’t directly add them, they may still unintentionally absorb into the plant.

Because of their high concentrations, pesticides in CBD oil can be dangerous to human and pet health. 

Heavy metals 

Although not intentional, many hemp-derived CBD products contain heavy metals. This can include lead, methyl mercury, and arsenic. Since hemp is so absorbent, if the soil it’s grown in is not safe, neither is the product. 

Residual solvents 

Solvents like butane, ethanol, and CO2 are popular choices for extraction. Laboratories can test to make sure these solvents are not in the final product. Leaving impurities like residual solvents in CBD can be harmful to users’ health.

Microbial

Microbial tests look for microbes and bacteria found in plants. These can include salmonella, yeast, and molds. Your COA may or may not have a microbial analysis. 

Terpene profile 

Terpenes are nothing to worry about. They are compounds in cannabis and hemp that are responsible for its unique taste and aroma. Cannabis and hemp plants have many terpenes. Different terpene profiles lead to different effects, flavors, and smells. 

How to read a COA for CBD 

Now that we’ve answered “what is a coa?”, we’ll walk you through the process of reading it. 

Step-by-step instructions for reading a CBD COA 

  1. Verify the test is credible. 

If the CBD company in question also performed their tests, it’s not reliable. It’s important to make sure the test was conducted at a third-party, ISO-accredited laboratory. Otherwise, there may be bias in the reported results. 

You can usually find this information on the top left of the page. First, check the name of the laboratory that conducted the test. Make sure it doesn’t match the name of your product. Then, confirm that the sample and batch number and check the date. 

  1.  Check the cannabinoid content.

 This verifies the amount of CBD is accurately labeled. Look for D-9 THC and ensure the concentration is below 0.3%. It’s crucial to verify that this test includes all components based on the product type. If it’s full-spectrum of broad-spectrum CBD, it should have a full analysis of all of the other cannabinoids present. 

  1. Read the pesticide report. 

Units will be listed as ‘ppb’ which stands for parts per billion. You’ll see ‘LLD’ in one column, indicating the “lower limit of detection” for each listed pesticide. Under ‘Limits’ you’ll see the maximum allowance based on individual state guidelines. Match these up to ensure the product falls within limits. 

  1. Check the heavy metals analysis. 

This should show all of the metals tested and their chemical names and symbols. Scan through the concentrations. MDL is the lower limit of detection that lab tools can reach.

 ‘Use Limits’ and ‘Ingestion’ refer to the determined allowance by the state Department of Public Health and Pharmacopeia. If the number falls below the set limits, it’s determined to be safe for regular ingestion. 

  1. Read through the terpene profile analysis.

 You can look at the exact terpene profile of your product on the COA. Results will show the detected amount of terpenes by weight percent. 

  1. Check through any other results listed.

 Look over the microbial analysis and residual solvent tests to ensure purity. You’ll find an “ND” listed for each. This means “none detected.”

  1. See what’s missing from the report. 

Empowered consumers can decide exactly what they will and will not accept from their test results. But if they overlook major areas, such as pesticides, it’s a good idea to reach for a different product. 

Final thoughts for those wondering “what is a COA?”

Unfortunately, the CBD industry is susceptible to fraud. In fact, it’s an unregulated market. This makes it easy for some manufacturers to lie about their products for better financial gain. 

Additionally, it’s also an industry that is susceptible to unintentional misreporting. If a lab tries to test their own products for better transparency, they may have good intentions. But those good intentions may result in improper testing procedures or faulty equipment. 

The end result is the same: Improperly labeled CBD that is potentially dangerous to humans and their pets. 

The solution is to only purchase tested CBD products. Make sure the testing happens at ISO-accredited laboratories. Laboratories with ISO accreditation have proven they can conduct tests in accordance with industry standards. This eliminates room for error or fraud within the industry. 

Remember to always check the COA on your CBD products. Consumers must hold companies accountable to provide safe, quality products. If you can’t access a COA, move on to a more transparent CBD product. 

What Pesticides Can Be Found In CBD Oil?

Some CBD products contain pesticides. There is no governing force preventing this right now. A consumer’s best defense is to check the Certificate of Analysis (COA) on the label. This displays what tests were conducted and their results. 

How worried should you be about pesticides in CBD? Well, one report found 70% of tested products were contaminated. The culprits included heavy metals such as arsenic and lead. They also found herbicides including the active ingredient in RoundUp, pesticides, BPA, and even toxic mold. Consumers should be concerned.

The Environmental Protection Agency (EPA) clarified hemp regulations in 2019. They added hemp to an approved list for 10 different pesticides. Nine are biopesticides that occur naturally and can control pests. One is a conventional pesticide (synthetic chemical that works by killing pests). So, according to the EPA, there are 10 types of pesticides for use on hemp. 

This is good news for CBD users and those who produce it. High-risk, dangerous pesticides are not approved for use. This allows farmers to only use pesticides deemed safe for consumption. 

It’s not all good news, though. Even if the only pesticides present are approved, residue may still exceed safe limits. This potentially puts users at risk. Plus, acceptable residue levels are still unclear as the EPA navigates figuring out what pesticide residue levels are safe for human consumption. 

Keep in mind that some producers may still choose to use harmful, illegal pesticides in their CBD. After all, there is no requirement to test the CBD for pesticides before it hits the shelves. What’s stopping producers from just going for it? 

How do pesticides end up in CBD? 

Some manufacturers may choose to use pesticides to keep their plants free of pests. Unfortunately, it’s difficult to flush plants clean of these pesticides. It can cause mold, another issue within the industry. 

Hemp is extremely absorbent. It absorbs pesticides applied directly to its surface. But it goes beyond that. It also absorbs contaminants in the ground through its roots.  What you apply to and around the plant will remain a part of it. These pollutants can become even more concentrated when extracted into a CBD oil. 

What are the dangers of pesticides in CBD? 

If you go down the list of accepted pesticides for hemp, you may notice most seem generally safe. Most are naturally-occurring, after all. But excess residue may still be dangerous. There is also a risk that other contaminants are present. Even if they’re not listed. 

And if you’re wondering, “do people actually do that?”, the answer is yes. Take this story, for example: Two cannabis dispensaries had to close their doors in 2018 because some products tested positive for pesticides. Not just any pesticides, either, but bifenthrin, a prohibited pesticide for use in cannabis. 

The EPA considers Bifenthrin to be a possible human carcinogen. The state of Massachusetts had already banned the use of bifenthrin for cannabis. The positive test results prove that banned pesticides are still in use.

According to Leafly, pesticide residue is worse in concentrates than it is for the plant itself. Hemp and cannabis have different growing regulations but are very similar in structure. Pesticides in cannabis concentrates are worse than pesticide residue on the plant. This translates the same with hemp. 

Leafly states that “the processes used to concentrate cannabinoids also concentrate pesticides.” They noted that there may be nearly 10 times the amount of pesticides in cannabis concentrates than in cannabis flower. 

In the context of CBD, this is a problem. The majority of CBD products on the market are oils and tinctures, or concentrated forms of CBD. Users should not risk ingesting concentrated pesticides to relieve pain, anxious thoughts, or whatever it is they’re using CBD for. 

Red flags for purchasing pesticide-free CBD

If a product doesn’t have a COA available, be wary. Companies should be willing to share proof that they have complied with pesticide regulations. Their product should be labeled accurately for purity and potency. 

For the safest option, consumers should go a step further when purchasing CBD. Don’t just look for a product with a COA. Look for a product with a COA from an ISO-accredited laboratory

Why? Because CBD brands can easily do in-house testing or give their product to their buddy to “test” in their lab. This leaves a lot of room for error, whether intentional or not. Unfortunately, intentional mislabeling is common. Whatever can make the product sell better can sometimes take precedence over safety. 

CBD manufacturers pay laboratories to conduct tests for them. It’s no surprise that some of these testing companies may choose to omit potentially damaging results for their products. After all, their clients are the CBD manufacturers, not CBD consumers.  

That’s not to say all CBD companies are intentionally mislabeling their products. Some are testing with best intentions but doing so inaccurately. 

One study found one-third of cannabinoid content testing facilities in Washington state provided unreliable test results. Researchers concluded that one way to fix this issue is to only test in ISO-accredited laboratories. These labs have proven their compliance with industry standards. 

Tampered products

It’s common for in-house laboratories to use equipment that has a “limit of detection” known as LOD. This means that there is a minimum amount that can be detected in a sample. Even if a substance is present in a sample, if it falls below the equipment’s limit of detection, it will show nothing. Therefore, manufacturers can claim they tested zero for that substance. 

Pesticides in CBD face a similar issue. There is no federal regulation for CBD, meaning the limits of detections can vary across different labs

Unfortunately, this serves as a loophole for some manufacturers. By adding extra oil to their substance, they can dilute it until it detects zero. But this dilutes the entire product. It cuts back CBD content and displays a false negative to mislead consumers. 

What’s the solution for pesticides in CBD?

It’s clear that the industry needs more oversight. The EPA created a list of accepted pesticides recently. They are working towards a better, safer future for CBD. 

But CBD is still not required to be tested.  Manufacturers have plenty of room to deceive their customers. Until that changes, CBD users need to take their health into their own hands. 

Only buy CBD that has been tested from an ISO-accredited lab for the most reliable results. This ensures that the laboratory is able to conduct tests in line with industry standards. 

There are many exceptional CBD companies out there doing everything right. Seek those companies out.

Athletes and CBD: What to Know About Purity

pure-clean-premium-cbd-for-athletes

Athletes are turning to CBD for many reasons both before and after working out. The World Anti Doping Agency removed it from their Prohibited List, so an athlete can still use it if they’re in an affiliated sport. 

Those interested in CBD should pick a product that is pure, potent, and credible. They should select a product that provides third-party lab testing results from an ISO-accredited lab. It’s also important to choose the right type of CBD to get optimal results for athletes. 

In an unregulated market (no, the FDA is not regulating CBD), choosing a quality product can be tough. We broke down everything an athlete needs to know about CBD to equip others to make an informed purchase. 

CBD basics for the curious athlete

CBD is short for cannabidiol. It is typically derived from hemp, a low-THC, high-CBD type of cannabis. CBD is a molecule that naturally occurs in the cannabis plant. It is particularly abundant in hemp plants. 

CBD will not get you high. It interacts with cannabinoid receptors in different ways than THC does. Plus, hemp-derived CBD is legal in the United States so long as the THC level is at or below 0.3%, which is too low to get users high. 

If you’ve heard reports of CBD intoxication, the product probably had more THC than the label claimed. This can pose an issue for athletes avoiding THC. CBD products should be properly tested for purity and potency to avoid these kinds of issues. Products that have been tested will also prevent athletes from consuming toxins. 

Athletes can try CBD for pain relief, better sleep, and more

In the United States, 40% of CBD users use it to combat pain. Even some pet owners give their dog or cat CBD to relieve some effects of aging. With this in mind, athletes may find great value in the compound for recovery and pain relief. 

Its anti-inflammatory effects can be beneficial both before and after working out. CBD topicals, such as lotions or salves, can be rubbed directly on achy muscles and joints for localized pain relief and recovery. Tinctures and oils, CBD edibles, or CBD capsules can also deliver anti-inflammatory effects. 

CBD may also ease anxiety and improve sleep. Some athletes use CBD to ease their anxious feelings, improve their focus, or improve sleep. It may promote relaxation and stress relief before a big event or help athletes sleep better. Edibles, tinctures/oils, or capsules can all be used to reap CBD’s beneficial effects on anxiety and sleep. 

CBD can be vaporized, too, with concentrates or flower. Now, athletes know that it’s important to have a good lung capacity if you want to be the best you can be. Vaping is easier on the lungs than smoking, delivers effects quickly, and can be used for all purposes. But if you are looking to optimize lung health, it may be a good idea to reach for a different method of administration. 

CBD affects everyone differently. Biology, dosage, method of administration, and the purity and potency of the product all affect this. If the CBD is no good, the results will not be either.  

How to choose and dose CBD for athletes

There is no universally accepted CBD dosage. Most products will have a recommended dosage on the package and you can adjust from there. If your product has a recommended dose, start with the low end of the recommendation and adjust accordingly. 

If you’re not sure where to begin, anywhere between 15-25 mg is a good starting point. Pay attention to how you feel and adjust your dose over time until you feel you’re getting optimal results. 

Your dose will also depend on if you use CBD isolate, broad-spectrum, or full-spectrum CBD. Isolate contains no THC, while full-spectrum contains some THC and other cannabinoids. Broad-spectrum CBD contains CBD and other cannabinoids excluding THC. Some find broad and full-spectrum CBD to be more therapeutic because the plant parts synergize. 

It’s common for athletes to choose CBD isolate if they’re worried about potential THC showing up on a drug test. CBD isolate (or products tested as “THC free”) should not cause users to fail a drug test. If the product is improperly labeled or the athlete consumes enough for trace amounts to add up, they may run into problems. That’s why it’s important for athletes to choose products that have been tested for purity and potency.

Final thoughts for athletes using CBD 

Whether  to combat anxious feelings, relieve everyday stress, improve focus, or boost post-workout recovery, CBD may be beneficial for athletes. But it must be a quality product. 

CBD should be tested to verify its purity and potency. This ensures there are no toxins, solvents, or other substances present in the product. The easiest way to get quality CBD is to choose a product that has been tested by an ISO-accredited laboratory. This ensures their testing methods are up to standard. 

CBD Bioavailability: Optimizing for Tinctures and Oils

purity-and-potency-premium-cbd

CBD bioavailability is an important topic. Bioavailability means how much of a substance actually makes it to the bloodstream without elimination on its way to the target.  When taken by mouth, drugs break down in the digestive system before reaching the bloodstream. The amount that makes it to the bloodstream is lower than what was originally ingested because the body eliminates some of it.  Bioavailability varies based on the method of consumption and the purity and potency of the product in question. If you want to get the most out of your CBD, pay attention to bioavailability. 

What is the best method to take CBD oil or tincture?

If you eat CBD or swallow drops from a tincture or oil, the digestive system will break it down first. This decreases bioavailability. Some reports have shown the bioavailability of CBD to be less than 10% when consumed orally. 

The best method for taking CBD tincture or oil is the sublingual method. Leave the solution under your tongue for 60-90 seconds and then swallow. The glands under your tongue will absorb the majority of the CBD and the remainder can be swallowed.  CBD bypasses the digestive system and goes straight to the bloodstream when taken sublingually. Reports have shown that sublingual administration enhances bioavailability. The exact amount is unclear with different publications claiming anywhere from 13 to 35%

How can I boost CBD bioavailability? 

The best way to increase bioavailability is to take the product sublingually. Choose a quality product with a focus on purity and potency. This will ensure that you’re not absorbing any other substances or contaminants. To find pure and potent CBD, look for products that have been third-party tested by an ISO-accredited laboratory.

Laboratories with ISO-accreditation have proven their ability to meet industry testing standards. The company should provide a copy of their Certificate of Analysis (COA) detailing their test results. You can check the purity and potency of the CBD by reading the product’s COA. Each batch test should at least check for chemicals, pesticides, and solvents. Some companies will go even further and check for additional impurities such as heavy metals. Testing covers potency as well. The product must fall at or below 0.3% THC to meet legal standards and prevent intoxication. It’s also important that the product actually contains the amount of CBD it claims. There have been plenty of cases where the number on the label does not match what the actual test results show. If you’re buying CBD with bogus amounts, you’ll never know what your proper dose is. 

What is the right CBD dose? 

There is no universal CBD dosage. Bioavailability varies across different methods of administration. You may never know exactly how much CBD you’re getting, even when you take a set amount. Figuring out how much CBD is right can be a process.  Start with a low dose anywhere around 15-25 mg and pay attention to how you feel after taking it.  It typically takes 15-20 minutes for sublingual CBD to take effect, though you may need to experiment a bit before finding the perfect amount.  Luckily, CBD has been found to be safe even in very high doses. It’s very unlikely that users would take too much and experience adverse effects. One rodent study found potential liver problems or adverse reactions to certain medications, though. So if you’re considering taking CBD, it’s worth discussing with your doctor first, especially if you have other conditions. 

Final thoughts 

When it comes to CBD, what you see isn’t always what you get. That’s why products should always be tested by third-party laboratories with ISO-accreditation. But it goes beyond that.  CBD’s effects vary across different users, products, and reasons for taking it. If you want the most relief from your CBD, be sure to pay attention to bioavailability when deciding how to take it. The better the bioavailability, the better your results will be. 

CBD Testing: Why should lab results be ISO Accredited?

CBD Lab Testing

CBD testing is critical if you’re interested in purity and potency. If you’ve spent time reading about CBD, you know the importance of purchasing third-party lab tested products.

Since the FDA is not currently regulating the substance, many dangerous or misleading products exist in the market. The best consumer defense against unsafe CBD is to purchase from a producer that has tested their products in an unaffiliated, ISO accredited laboratory to verify its contents. 

CBD companies are not currently required to test their products. It’s up to individual companies to seek third-party testing and share results with consumers in the form of a Certificate of Analysis (COA). A COA is a document that ascertains the product has met its specifications by providing the list of ingredients, the batch number, method of analysis used, and the conclusion of the report, among other aspects.

No matter the reason for using CBD, whether it’s to manage pain or anxiety or provide relief for a senior pet, it should be tested to verify its potency, purity, and overall safety.  

It’s important that the COA comes from an ISO accredited lab, though. If a company provides results from their own in-house testing, it is potentially inaccurate. Instead, consumers should always opt for CBD that has been tested for purity according to best practices. A couple of brands that exemplify excellent testing practices are Mission Farms CBD out of Oregon and Pure Relief hailing from North Carolina.

What does ISO mean?

ISO refers to the International Organization for Standardization. This is a group that started in 1946 with delegates from 25 countries meeting up to discuss the future of standardization across nations. 

Today, ISO remains an independent, non-governmental, international organization. Collectively, they have developed over 23,112 International Standards across various industries. 

The organization describes its standards as “a formula that describes the best way of doing something.” Whether it’s making a new product, supplying materials, or managing a process, standards exist to ensure it’s done right. 

Manufacturers, sellers, customers, buyers, users, and regulators are among the many people involved in setting standards as they are either experts in the field or understand the needs of the organization they’re representing. 

What does ISO accreditation mean? What about certification?

When looking into ISO accreditation, you may notice the term “ISO accredited” or “ISO certified” being thrown around. The two are very similar, but not the same. 

ISO certification is a written assurance or seal of approval from a third party to a company as a whole. It serves to prove that the organization is compliant with relevant standards, though it does not require implementing additional means of quality control. 

ISO accreditation is a formal recognition of an establishment’s ability to meet specified standards for a specific process. This comes as an independent, third-party endorsement of a certification.

Don’t worry if you’re confused. The two are often used interchangeably in error, which can make it even more difficult to sift through. Essentially, certification serves as a third-party endorsement of a company’s processes as a whole, and accreditation serves as a third-party endorsement of one aspect.

So, laboratories can receive accreditation for their specific activity: testing. When consumers see lab results from an accredited laboratory, they can trust that the testing processes were conducted in compliance with their accreditation. 

Types of lab accreditation 

Remember, there are thousands of standards created by ISO. Each applies to a different industry or subsection of an industry. 

When it comes to laboratory testing, ISO/IEC 17025 is the main standard. According to ISO, 17025 “specifies the general requirements for the competence, impartiality and consistent operation of laboratories.”  It applies to any organization that performs laboratory work, no matter the size. 

Compliance with ISO 17025 standards is considered proof of competence for a laboratory. Even if a testing lab is compliant with all aspects of ISO 17025 standards, if they’re not accredited, the general public will not be aware. In order to be formally recognized as compliant, laboratories need to get their ISO 17025 accreditation. 

It’s important to keep in mind that the International Organization for Standardization (ISO) does not directly audit laboratories and accredit them. Rather, accreditation comes from organizations in specific areas. 

Accreditation organizations

The ANSI National Accreditation Board (ANAB), for example, is the largest accreditation body in the United States and works with organizations to obtain their accreditation. 

Accreditation bodies may define certain requirements for specific processes. For example, ANAB worked to establish specific requirements for their Cannabis Testing Laboratory Accreditation Program with requirements for laboratories that perform chemical and microbiological analyses for a variety of cannabis samples. 

Another accreditation body, A2LA, has laid out framework for cannabis testing. They have two paths, one for medical and one for recreational. Both require compliance with ISO 17025 standards. The medical accreditation requirements include meeting standards through other medical programs and the recreational path includes compliance with in-state requirements. 

Keep in mind that these regulations are cannabis-specific and do not extend to hemp. Hemp is the fibrous, low-THC variation of the cannabis plant that CBD is derived from. However, many industrial hemp and CBD companies will voluntarily conform to cannabis testing standards. 

CBD Testing: why ISO accreditation is important

Contrary to popular belief, CBD is not regulated by the FDA. So who is keeping watch over the industry and ensuring that the products are what they say they are? Unfortunately, nobody right now. 

This can be dangerous. There are many examples of CBD products being inaccurately labeled. In one example, reporters purchased nine random CBD-infused products (oils, candies, etc) and sent them in for laboratory analysis. Every product failed to match the information on the label. Most products contained less CBD than advertised. 

Not only can the CBD content be inaccurate, but unregulated products can also contain unsafe adulterants. In one report, one-third of commercially marketed products showed positive for synthetic and psychoactive adulterants. Some results showed zero CBD present in the products altogether. 

To verify that a CBD product actually matches its description, it needs to be third-party tested from an ISO-accredited lab. In-house testing may be inaccurate because the testing methods may not be correct or those conducting the tests may be willing to tweak the results in the company’s favor. 

ISO accredited labs take out all of the guesswork

In an unregulated market, ISO-accredited labs provide assurance of quality without bias or improper testing methods. Consumers know they’re testing products properly because they are ISO 17025 accredited. 

If the CBD product in question has been tested by an accredited, third-party laboratory, you can be certain that the testing was conducted properly and the results are accurate. 

CBD Testing: the bottom line 

  • The ISO (International Organization for Standardization) is an organization that establishes standards for a variety of industries. The group consists of manufacturers, sellers, customers, buyers, users, regulators, and other individuals. 
  • ISO describes its standards as “a formula that describes the best way of doing something.”
  • ISO accreditation can be obtained by an authorized accreditation body to prove compliance with industry standards. While the ISO is responsible for setting standards, the group does not accredit organizations. Instead, accreditation bodies conduct audits of different organizations to ensure their processes are compliant with standards. 
  • CBD companies should always test their products at an ISO-accredited, third-party laboratory to ensure quality. In an unregulated market, brands that go the extra mile to guarantee what you see is what you get are leading the way and providing safe access to CBD.
