CBC, a cannabinoid typically seen in hemp and CBD-rich plants, has been linked to some potentially impactful medical applications, much like the findings regarding the benefits of CBD. The module that tests for it, along with terpenes and degraded THC, can be added to the LightLab without any changes to hardware or sample preparation.

According to Dylan Wilks, chief technology officer of Orange Photonics, this could be a particularly useful tool for distillate producers looking for extra quality controls. Cannabis distillates are some of the most prized cannabis products around, but the heat used to create them can also create undesirable compounds,” says Wilks. “Distillate producers can see potency drop more than 25% if their process isn’t optimized”. With this new Terpenes+ Module, a distillate producer could quantify degraded THC content and get an accurate reading for their QC/QA department.
We spoke with Stephanie McArdle, president of Orange Photonics, to learn more about their instruments designed for quality assurance for growers and extractors alike.

According to McArdle, this could help cultivators and processors understand and value their product when terpene-rich products are the end goal. “Rather than try to duplicate the laboratory analysis, which would require expensive equipment and difficult sample preparation, we took a different approach. We report all terpenes as a single total terpene number,” says McArdle. “The analyzer only looks for monoterpenes (some common monoterpenes are myrcene, limonene and alpha-pinene), and not sesquiterpenes (the other major group of cannabis terpenes, such as Beta- Caryophyllene and Humulene) so the analysis is semi-quantitative. What we do is measure the monoterpenes and make an assumption that the sesquiterpenes are similar to an average cannabis plant to calculate a total terpene content.” She says because roughly 80% of terpenes found in cannabis are monoterpenes, this should produce accurate results, though some exotic strains may not result in accurate terpene content using this method.

As growers look to make their product unique in a highly competitive market, many are looking at terpenes as a source of differentiation. There are a variety of areas where growers can target higher terpene production, McArdle says. “During production, a grower may want to select plants for growing based on terpene content, or adjust nutrient levels, lighting, etc. to maximize terpenes,” says McArdle. “During the curing process, adjusting the environmental conditions to maximize terpene content is highly desirable.” Terpenes are also beginning to get recognized for their potential medical and therapeutic values as well, notably as an essential piece in the Entourage Effect. “Ultimately, it comes down to economics – terpene rich products have a higher market value,” says McArdle. “If you’re the grower, you want to prove that your product is superior. If you’re the buyer, you want to ensure the product you buy is high quality before processing it into other products. In both cases, knowing the terpene content is critical to ensuring you’re maximizing profits.”
Orange Photonics’ LightLab operates very similarly to instruments you might find in a cannabis laboratory. Many cannabis testing labs use High Performance Liquid Chromatography (HPLC) to analyze hemp or cannabis samples. “The primary difference between LightLab and an HPLC is that we operate at lower pressures and rely on spectroscopy more heavily than a typical HPLC analysis does,” says McArdle. “Like an HPLC, LightLab pushes an extracted cannabis sample through a column. The column separates the cannabinoids in the sample by slowing down cannabinoids by different amounts based on their affinity to the column.” McArdle says this is what allows each cannabinoid to exit the column at a different time. “For example, CBD may exit the column first, then D9THC and so on,” says McArdle. “Once the column separates the cannabinoids, they are quantified using optical spectroscopy- basically we are using light to do the final quantification.”
I worked for about 18 years as a company employee in various levels from entry-level engineer to senior director. Since then I have spent over a decade as a consultant in the life science industry as the founder of Sebald Consulting. Presently, I also use consultants as CEO of GxPready!, a web based CMMS software company. Based on this experience, I have put together a top 5 list of things you can do to get the most value when using consultants:
1. Recognize when a project requires a consultant
There can be several reasons a project may benefit from having a consultant which may include bringing a new skill set, industry experience or an outside perspective to bear on a project that is not available otherwise.
Provide clear guidance as to what the task and deliverables are on an ongoing basis.Also, there are occasions when resources are already stretched and you need short-term support to get through an intensive segment of a project, but the work may not be enough to justify additional longer-term resources.
In any of these cases, filling the gap internally can be difficult and time consuming. A consultant can be a great solution. Even if you don’t plan to use a consultant for the project, it may be to your benefit to have a consultant perform a “gap assessment” to help you to identify areas which require improvement to meet compliance requirements or best practice guidelines. This is often done to prepare for audits, for example.
2. Vet the consultant to get a good match
Contact potential consultants to determine if they have the set of skills you are looking for and if they fit within the culture of your organization. Talk to the actual consultant you will be working with before bringing them on. Review the consulting contract carefully to make sure the terms are mutually acceptable. Often consultants have some flexibility to accommodate different project situations.
One advantage to using consultants is that you don’t have a long commitment so even after you vet them with interviews, you can work on small projects and gauge the results. Some consulting companies are very formal and others are less so, for example. A good fit is better for both parties. It’s not just the competence, but the culture and personal fit with your team.
3. Provide the consultant with appropriate guidance and resources
Help the consultant give you the best results possible by providing access to the resources (personnel, information, documents, systems, etc.) to allow the consultant to perform the tasks.
Consultants can help you get through unfamiliar territory or help you to manage your team’s workload. Know how to use these resources to benefit your projects. This project manager called just in time.
Provide clear guidance as to what the task and deliverables are on an ongoing basis.
Alternatively, allow the consultant to manage the project and reach out as necessary. Any guidance and resources you can provide the consultant will increase the effectiveness and help control your costs on the project.
If you don’t know exactly what needs to be done (“That’s why I hired a consultant!”) then have the consultant put together a list for you based on some general guidance and then work from that list to get your job completed.
4. Track progress with appropriate level of detail
If you have vetted and hired a consultant, chances are they are going to put in their best effort to meet your requirements. Nonetheless, it is good practice to have a system in place to track hours/costs.
Whether it is weekly reporting, or based on milestones and project updates, this helps to avoid any misunderstandings and provides opportunities for communication of project issues in addition to whatever project updates may be scheduled.
You want your team of consultants and employees to be able to work as well as possible together.Recognize that you can go overboard in this area, working against yourself and the project, if the tracking is so detailed that it takes excessive resources to document. It is definitely possible to inadvertently generate more hours (and expense) by managing time in too much detail. If the concern is high and heavy management is required, perhaps that indicates the consultant is not the best match for this project.
Generally, you can find a good balance with a simple up-front chat with the consultant to review your expectations, and for larger projects it is often formalized in the contract.
5. Recognize if it’s not a good fit
There are many consultants and clients out there. Inevitably, there are times when, despite best intentions, the consultant/client mix isn’t working out. Make sure the contract allows for management of this situation. Can you cancel the contract with reasonable notice? Is there a mechanism for being able to replace members of the team that aren’t working out?
You want your team of consultants and employees to be able to work as well as possible together. If that’s not happening, recognize it and make adjustments as necessary. But don’t lose the contact information. A consultant that doesn’t work out today may be just right for your next project!
Following the above can improve your chances of success with consultants you may hire and allow you to build a solid set of resources you can call on from time to time as things change in your company. Consultants can fill a vital role for tasks requiring specialized skills or short-term projects where a full time hire is not practical.
At the National Cannabis Industry Association’s (NCIA) Cannabis Business Summit and Expo last week there was a presentation titled, “Raising the Standard for Dispensary Education: Building a Better Breed of Budtender.” Speakers included Adam Cole, learning and development specialist at Native Roots Dispensaries and Dr. Aseem Sappal, provost and dean of faculty at Oaksterdam University. Nancy Whiteman, owner of Wana Brands, was the moderator. Let’s look at some of the ways they have standardized their process in cannabis retail education.Health effects achieved in one patient are not always replicated for every patient. This is true of all medicine.
The standard education module at Native Roots (20 retail locations throughout Colorado, and were awarded licenses in Manitoba, Canada) for onboarding a budtender includes laws and compliance, ID checking and sales limits, customer service and physical effects. Oaksterdam University provides cannabis education and focuses on botany, introduction to the endocannabinoid system, bioavailability, CBD, and edibles vs. smoking as a delivery mechanism. In addition to the already mentioned classes, Wana Brands also teaches the concept of sustained release and capsules (due to product specificity). The Native Roots educational program contains continuing education in the history of cannabis, the endocannabinoid system, methods of consumption, phytocannabinoids and terpenes. For those of you in medical professions beginning your cannabis education, these modules provide a great outline to launch your own learning and development program.
How can dispensaries integrate the medical profession at the point of distribution?The presentation highlighted the legal aspects of providing cannabis information and cannabis products. A licensed medical professional oversees all educational content and everything is run through a legal department. It is important that all cannabis providers use language that offers no definitive medical outcomes. Health effects achieved in one patient are not always replicated for every patient. This is true of all medicine. At Native Roots Dispensary, they address symptoms not diseases. They have specific language to avoid giving medical advice. For good reason, there is a state regulatory body called the Marijuana Enforcement Division (MED) that oversees dispensaries and their adherence to the “no medical advice” decree, along with a slew of other regulatory compliance issues.
Dispensaries offer careful symptom-based product recommendations to many types of consumers. How can dispensaries integrate the medical profession at the point of distribution? Native Roots has partnerships with doctors and the Rocky Mountain Cancer Institute. Additionally, the CEO of Wana Brands mentioned the use of medical kiosks in some dispensaries. My question to Adam Cole was, “Would you like to see trained cannabis nurses on staff or on board as a consultant in dispensaries to deal with patients and have the budtenders service the customer?” His answer: “Absolutely.”
Lessthan a week after Cannabis Industry Journal reported that BfArM had finally cancelled the first German tender bid for cannabis cultivation, and after refusing to confirm the story to this outlet, the agency quietly posted the new one online, at 3.45pm Central European Time, July 19.
First Thing’s First
For those who have not seen it yet, here is a first look at the “new” bid auf Deutsch. It is basically identical to the last one. For the most part, Europe is shaping up to be a high volume ex-im market.For now, that is all that exists. However,a move is on in Europe to translate the bid into English. Why? To hold BfArM accountable. And to help educate all the foreign and for the most part, non-German speaking investors who want to know what is required to get the bid in the first place. The process last time left a great deal to be desired.
Bid Redux
Apart from this, however, very little seems to have changed from the last time. Notably,the amount to be grown domestically is the same. This means that the government is deliberately setting production below already established demand.

Why?
As has become increasingly clear, the German government at leastdoes not want to step into the cultivation ring. Further,because they are being forced to, the government wants to proceed slowly. That means that for at least the next couple of years, barring local developments, it is actively creating a market where imports are the only kind of cannabis widely available – for any purpose. And in this case, strictly medical. With many, many restrictions. Starting with no advertising.
Import Europe
For the most part, Europe is shaping up to be a high volume ex-im market. This was already in the offing even last year when Tilray announced the constructionof their Portuguese facilities last summer, and Aurora and Canopy began expanding all over the continent, starting in Denmark, but hardly limited to the same.
These days it is not the extreme west of Europe (Spain and Portugal) that are the hot growingareas, but the Balkans and Greece. Cheap labour, real estate and GMP standards are the three magic words to market entry.
Can This Situation Hold?
There are several intriguing possibilities at this point. The simple answer is that the current environment is simply not sustainable.
Clearly, it is two-fold. The first is to deleverage the power of financial success as a way of legitimizing the drug if not the “movement.” Further, if Germans want to profit from the legal cannabis market it is going to be very difficult. See the bid last year beyond this new development.
That means everyone else is going to have to get creative. The industry, advocates and patients have seen similar moves before. Patient access and profitability are not necessarily the same thing.An increasing numbers of companies are finding ways around being cultivators to get their product into the country anyway.
What Now?
The only problem with such strategies, just like banning German firms from competing in the bid, is that “prohibition” of this kind never works.
It will not keep cannabis out of Germany. The vast majority of the medical cannabis consumed by patients in Germany will come from the extremes – of east and western Europe – with Canadian, Dutch and even Danish stockpiles used as necessary. It will also not discourage the domestic cannabis movement here, which is critical as ever in keeping powerful feet to the fire.
It will also not discourage German firms from entering the market – in a variety of creative ways. Most German cannabis companies are not public, and most are setting themselves up as processors and distributors rather than growers.
So in summary, the bid is back. But this time, it is absolutely not as “bad” as ever. An increasing numbers of companies are finding ways around being cultivators to get their product into the country anyway.
As for raising money via public offerings? There are plenty of other countries where the publicly listed, now banned North American companies can raise funds on public exchanges (see Sweden and Denmark) as they target the cannabis fortress Deutschland.
The National Cannabis Industry Association (NCIA) announced earlier this week the release of two white papers at their Cannabis Business Summit in San Jose, California.The first white paper, dedicated to cannabis testing policy, offers recommendations for state’s addressing cannabis testing, advising them on how to write rules for the testing market.“As wonderful as cannabis is, we’ll face a crisis together as an industry way too soon. When it happens, the key will be how we respond to it,” says Moss.
The NCIA Policy Council is like a think tank for helping for and shape state and federal level policy related to cannabis. Kurshid Khoja, principal at Greenbridge Corporate Counsel and member of the Policy Council, says this release of the testing policy recommendations demonstrates how we can help shape policy on the state level. “As both an NCIA Board member and a member of the Policy Council, I am really excited about the Council’s work,” says Khoja. “Somewhat under the radar, the Policy Council is establishing itself as the think tank for the cannabis industry. On topics ranging from tax policy to pesticides to international competition, the Policy Council is churning out quality papers to raise awareness and educate policy makers in DC. With the release of its testing policy recommendations this week, the Policy Council is demonstrating that it could also help shape policy on the state level.”
The second white paper is meant to provide guidance to businesses dealing with crisis communications. The manual describes best practices in crisis communications, showing businesses how to identify and avoid potential public communications issues in the cannabis industry.
Jeanine Moss, Crisis Manual Subcommittee Chair of NCIA’s Marketing & Advertising Committee, says the creation of a crisis manual is meant to preempt problems we might face soon in the cannabis industry. “As wonderful as cannabis is, we’ll face a crisis together as an industry way too soon. When it happens, the key will be how we respond to it,” says Moss. “That’s why we think it is so important for NCIA members to have an easy and practical guide that can not only help protect businesses during a crisis, but also the industry as a whole. This manual will help businesses prevent problems, keep issues from spiraling out of control, and share positive messages during times of stress.”
Calls for more testing have been a watchword of both cannabis reform advocates and opponents alike for many years.
However, now is a really good time for cannabis companies to consider sponsoring medical trials across Europe for their cannabis products. This is why:
The Current Environment On The Ground
Germany is Europe’s biggest consumer of both prescription medications and medical devices dispensed by prescription. It is, as a result, Europe’s most valuable drug market. And ground zero for every international cannabis company right now as a result.Targeting Germany for your latest pharmaceutical product is difficult no matter who you are.
Here, however, are a few problems that face every pharma manufacturer, far beyond cannabis. Targeting Germany for your latest pharmaceutical product is difficult no matter who you are.
The vast majority by euro spending on all drugs and devices dispensed by prescription must be pre-approved. To add to this problem, before they can be prescribed, new drugs must get on the radar of doctors somehow. To put this in stark relief, the entire prescription drug and medical device annual spend is about 120 billion euros a year in Germany. Only 20 billion euros of that, however, may be obtained relatively easily (without pre-approval from an insurer). Preapproval also only comes when there is trialor other scientific evidence of efficacy.
There are strict rules banning the advertising of prescription drugs to patients and highly limiting this outreach to doctors.
There are strict rules prohibiting the use of the word “cannabis” to promote anything.
There is a strong reliance on what is called “evidence-based medicine.” That means that large numbers of doctors and insurance company approvers need to see hard data that this drug or device actually works better than what is currently on the market.
How then, is a new drug supposed to get on the radar of those who prescribe the drug? Or patients?
If this sounds like an impossible situation to navigate, do not despair. There is a way out.
Largely unknown outside Europe, this agency actually has a hugeinfluence on how drugs are brought into the region. Specifically, this is the EU-wide agency (aka the EMA) that both regulates all drugs within Europe, but has also, since 2016, been making clinical reports submitted by pharmaceutical companies, available to anyone who asks for them. That includes doctors, members of the public and of course, the industry itself.
In the middle of July, the agency also published a report on the success of its now three-year-old program, including the usage of its entry website. Conveniently written in English, it is possible to easily search new trial data, which, also now must be made public.
Medical trial data, in other words, that can be created by sponsored cannabis company backed trials.
It remains the best way to get patients, doctors and insurance companies familiar with new drugs. Or even new uses for old drugs in the case of cannabis.
Will Trials Move Legalization Discussions?
Of all the established cannabis companies now in operations with producton the ground, GW Pharmaceuticals has learned that this strategy can actually cut both ways.
However,there are no other cannabis companies in the position of GW Pharma – namely with a monopoly on a whole country (the UK), where it alone can legally grow cannabis crops and process the same into medication and further for very profitable export. In addition, even more disturbingly, and clearly an era that is coming to an end, the vast majority of British patients have been excluded from access to cannabis except in the case of GW Pharma products.
GW Pharma said their product Epidiolex (for the treatment of childhood epilepsy) is being considered by the European Medicines Agency
However, that is the UK.
Other cannabis companies can take a page out of the company’s handbook. All that is required for faster market entry, is a slightly altered recipe.
By sponsoring cannabis-related trials in each country they want to enter, starting with Germany, cannabis companies can literally put themselves on the medical map.
Why?
Because doctors, patients andother researchers will be easily able to see and access country-specific medical data on each use of cannabis covered by a trial, per EU country. All made possible, of course, by the new open door policy of the EMA.
Growing the Medical Market
While this may sound like an “expensive” proposition, there are really few other alternatives. And with no advertising budget, plus a marketing budget that must include outreach to everyone in the supply chain including doctors, distributors and even pharmacies, the trial approach in the end may be the most efficacious in broadening both the demand and market. Not to mention the cheaper option.
How such a trial strategy might be coordinated at a time when domestic cultivation is still on hold is still a question. However for those companies considering market entry and cultivation bid if not domestic processing strategies for their products is an industry strategy that will pay off in spades.
Its role in the legalization of cannabis as medicine, as well as the speedier introduction of new drugs overall into the European system,cannot be underestimated, even if it is currently underutilized by the cannabis industry specifically now.
Federal trademark registrations are invaluable tools for emerging businesses. They put the world on notice of a company’s name; they can secure nationwide priority over others using similar names; they distinguish a product in the marketplace; they provide crucial advantages in trademark infringement lawsuits; and they are instrumental in building goodwill. But if you sell cannabis, a federal trademark registration will not do any of those things for you … because you can’t get one.
Someday, the USPTO policy may change and there could be a gold rush for federal cannabis trademark registrations.The United States Patent and Trademark Office (USPTO) continues to refuse to register federal trademarks for cannabis businesses, even if the sale of cannabis is legal in the state where the businesses are located. The USPTO’s reasoning goes something like this: federal trademark law allows for the registration of trademarks associated with goods in “lawful” commerce, which means that the goods are not illegal under federal law. Cannabis, and its psychoactive component, THC, remain Schedule I substances under the federal Controlled Substances Act (CSA). Therefore, irrespective of state laws to the contrary, and irrespective of whether the federal law is actually enforced, the manufacture and sale of cannabis is not “lawful” commerce.
This reasoning is of fairly recent vintage. In 2009, by which time about fifteen states had legalized medical cannabis, Attorney General Eric Holder announced that the Drug Enforcement Administration would cease raids on state-sanctioned medical cannabis facilities. The USPTO followed Holder’s lead in 2010 and created a new category of acceptable goods and services for marks related to “medical marijuana.” Within months, however, the USPTO had retreated from this “mistake” and changed its practice manual expressly to preclude such registrations.
David Kluft, partner in the Boston office of Foley Hoag, LLP
Many argue that the USPTO’s position is unjustifiable as a matter of public policy. Making it easier to infringe the trademarks of state-sanctioned businesses does not advance the purposes of the CSA, and it directly undermines a key goal of trademark law, which is to prevent the proliferation of confusingly similar trademarks. But the merits of these arguments have been lost on the USPTO, which continues to refuse to register marks for anything it perceives to be prohibited by the CSA.
So if you own a cannabis business, what can you do to protect your goodwill while the federal government maintains its current policy? Below are some ideas. Admittedly, none of them– individually or collectively – is a substitute for federal registration. But each of them is better than nothing, and all of them may help to establish your ownership and priority when and if the USPTO changes its policy.
State Trademark Registrations. Each state has its own trademark registration system. State registration may offer protection from infringers within the state, or at least within the parts of the state where the registrant operates, and for that reason alone it is probably worth the small cost involved. However, state registration will have little to no efficacy outside the state. You cannot use a State A registration to file a lawsuit in State B, or to stop infringement in State B, or even to prevent conflicting registrations in State B. Additionally, most state trademark registrants, unlike federal registrants, do not benefit from presumptions of validity and ownership in the litigation context.
Related Federal Registrations. Many cannabis businesses also pursue federal registrations for whatever aspects of their business are not prohibited by the CSA. For example, even though the USPTO refused the POWERED BY JUJU mark for cannabis vaporizers (because it was CSA-prohibited “paraphernalia”), it allowed the same company to register the same mark for “vaporizers for smoking purposes not for use with cannabis.” The USPTO has also allowed registrations for cannabis-related business consulting (e.g., CANNACARD; PRAIRIEJUANA); investment analysis (e.g., FORTUNE420); clothing (e.g., CANNABIS COUTURE, THE MARIJUANA COMPANY); and for CBD – as opposed to THC – derivatives (e.g., CBD LIQUID GOLD). Once the USPTO permits federal registrations for cannabis marks and the inevitable disputes over ownership arise, such federal registrations for these related products and services are likely to be highly persuasive evidence in the registrants’ favor. Moreover, even in the current legal climate, federal registrations (especially when cited in a demand letter) are of great practical use in convincing others not to use confusingly similar marks.
Common Law Unfair Competition. Unfair competition is a state common law cause of action that was a precursor to modern trademark law, and it is still available to protect commercial goodwill even in the absence of a state or federal trademark registration. However, unfair competition law has similar territorial restrictions as state registration. In some cases, the protected territory may be even narrower, limited only to the area within which the plaintiff can prove consumer recognition of the mark.
Other Intellectual Property Protection. Copyright law, unlike federal trademark law, has no “lawful” commerce requirement, and the U.S. Copyright Office regularly issues registrations for cannabis-related copyrights. While copyright will not protect a short phrase such as a business name, it will protect a creative logo design or original packaging, and can be very effective when it comes to getting infringing uses taken down from the internet. Note also that the USPTO does not appear to have the same qualms about legality when it comes to patents, and it often grants patent protection to useful, new and non-obvious inventions related to the cannabis industry.
Save stuff. Finally, if you do nothing else, save stuff. Document that first sale; keep a copy of that first shipping invoice; and save that file containing your original packaging design. Someday, the USPTO policy may change and there could be a gold rush for federal cannabis trademark registrations. Your lawyer is going to ask you for proof of your first uses of the mark, and you don’t want your response to be a glassy stare. So keep your eyes on the eventual prize and stay ready.
Editor’s Note: The views expressed in this article are the author’s opinions based on his experience working in the laboratory industry. This is an opinion piece in a series of articles designed to highlight the potential problems that clients may run into with labs.
In the last two articles, I discussed the laboratory’s first line of defense (e.g. certification or accreditation) paperwork wall used if a grower, processor or dispensary (user/client) questioned a laboratory result and the conflicts of interest that exist in laboratory culture. Now I will discuss the second line of defense that a laboratory will present to the user in the paperwork wall: Quality Control (QC) results.
Do not be discouraged by the analytical jargon of the next few articles. I suggest that you go immediately to the conclusions to get the meat of this article and then read the rest of it to set you on the path to see the forest for the trees.
QC in a laboratory consists of a series of samples run by the laboratory to determine the accuracy and precision of a specific batch of samples. So, to start off, let’s look at the definitions of accuracy and precision.QC Charts can provide a detailed overview of laboratory performance in a well-run laboratory.
Accuracy: estimate of how close a measured value is to the true value; includes expressions for bias and precision.
Precision: a measure of the degree of agreement among replicate analyses of a sample.
A reputable laboratory will measure the Accuracy and Precision of QC samples in a batch of user samples and record these values in both the analytical test report issued to the user and in control charts kept by the laboratory. These control charts can be reviewed by the user if they are requested by the user. These control charts record:
Accuracy (means) chart: The accuracy chart for QC samples (e.g., LRB, CCV, LFBs, LFMs, and surrogates) is constructed from the average and standard deviation of a specified number of measurements of the analyte of interest.
Precision (range) chart: The precision chart also is constructed from the average and standard deviation of a specified number of measurements (e.g., %RSD or RPD) for replicate of duplicate analyses of the analyte of interest.
Now, let’s look at what should be run in a sample batch for cannabis analyses. The typical cannabis sample would have analyses for cannabinoids, terpenes, microbiological, organic compounds, pesticides and heavy metals.
Each compound listed above would require a specific validated analytical method for the type of matrix being analyzed. Examples of specific matrixes are:
Cannabis buds, leaves, oil
Edibles, such as Chocolates, Baked Goods, Gummies, Candies and Lozenges, etc.
Vaping liquids
Tinctures
Topicals, such as lotions, creams, etc.
Running QC analyses does not guarantee that the user’s specific sample in the batch was analyzed correctly.
Also, both ISO 17025-2005 and ISO 17025-2017 require the use of a validated method.
ISO 17025-2005: When it is necessary to use methods not covered by standard methods, these shall be subject to agreement with the customer and shall include a clear specification of the customer’s requirements and the purpose of the test and/or calibration. The method developed shall have been validated appropriately before use.
ISO 17025-2017: The laboratory shall validate non-standard methods, laboratory-developed methods and standard methods used outside their intended scope or otherwise modified. The validation shall be as extensive as is necessary to meet the needs of the given application or field of application.
The laboratory must have on file for user review the following minimum results in an analytical statistical report validating their method:
accuracy,
limit of quantitation,
ruggedness,
precision,The user must look beyond the QC data provided in their analytical report or laboratory control charts.
linearity (or other calibration model),
confirmation of identity
selectivity,
range,
spike recovery.
limit of detection,
measurement uncertainty,
The interpretation of an analytical statistical report will be discussed in detail in the next article. Once the validated method has been selected for the specific matrix, then a sample batch is prepared for analysis.
Sample Batch: A sample batch is defined as a minimum of one (1) to a maximum of twenty (20) analytical samples run during a normal analyst’s daily shift. A LRB, LFB, LFM, LFMD, and CCV will be run with each sample batch. Failure of any QC sample in sample batch will require a corrective action and may require the sample batch to be reanalyzed. The definitions of the specific QC samples are described later.
The typical sample batch would be set as:
Instrument Start Up
Calibration zero
Calibration Standards, Quadratic
LRB
LFB
Sample used for LFM/LFMD
LFM
LFMD
Samples (First half of batch)
CCV
Samples (Second half of batch)
CCV
The QC samples are defined as:
Calibration Blank: A volume of reagent water acidified with the same acid matrix as in the calibration standards. The calibration blank is a zero standard and is used to calibrate the ammonia analyzer
Continuing Calibration Verification (CCV): A calibration standard, which is analyzed periodically to verify the accuracy of the existing calibration for those analytes.
Calibration Standard: A solution prepared from the dilution of stock standard solutions. These solutions are used to calibrate the instrument response with respect to analyte concentration
Laboratory Fortified Blank (LFB): An aliquot of reagent water or other blank matrix to which known quantities of the method analytes and all the preservation compounds are added. The LFB is processed and analyzed exactly like a sample, and its purpose is to determine whether the methodology is in control, and whether the laboratory is capable of making accurate and precise measurements.
Laboratory Fortified Sample Matrix/Duplicate (LFM/LFMD) also called Matrix Spike/Matrix Spike Duplicate (MS/MSD): An aliquot of an environmental sample to which known quantities of ammonia is added in the laboratory. The LFM is analyzed exactly like a sample, and its purpose is to determine whether the sample matrix contributes bias to the analytical results. The background concentrations of the analytes in the sample matrix must be determined in a separate aliquot and the measured values in the LFM corrected for background concentrations (Section 9.1.3).Laboratories must validate their methods.
Laboratory Reagent Blank (LRB): A volume of reagent water or other blank matrix that is processed exactly as a sample including exposure to all glassware, equipment, solvents and reagents, sample preservatives, surrogates and internal standards that are used in the extraction and analysis batches. The LRB is used to determine if the method analytes or other interferences are present in the laboratory environment, the reagents, or the apparatus.
Once a sample batch is completed, then some of the QC results are provided in the user’s analytical report and all of the QC results should be recorded in the control charts identified in the accuracy and precision section above.
But having created a batch and performing QC sample analyses, the validity of the user’s analytical results is still not guaranteed. Key conclusion points to consider are:
Laboratories must validate their methods.
Running QC analyses does not guarantee that the user’s specific sample in the batch was analyzed correctly.
QC Charts can provide a detailed overview of laboratory performance in a well-run laboratory.
The user must look beyond the QC data provided in their analytical report or laboratory control charts. Areas to look at will be covered in the next few articles in this series.
Imagine this: you are taking medication for cancer pain. One day, it works perfectly. The next, you feel no relief. On some days, you need to take three doses just to get the same effect as one. Your doctor can’t be completely positive how much active ingredient each dose contains, so you decide for yourself how much medication to take.
Doesn’t seem safe, right? It is crucial that doctors know exactly what they are prescribing to their patients. They must know that their patients are receiving the exact same dose of medication in their prescription each time they take it, and that their medication contains only the intended ingredients.
consistency is key to creating products that are safe for consumers.In the cannabis industry, lack of certainty on these important factors is a major problem for drug manufacturers as they attempt to incorporate cannabidiol (CBD), a compound found in cannabis that has no psychoactive effects but many medical benefits, into pharmaceutical drugs.
When using these compounds as medications, purity is essential. Cannabis contains a wide variety of compounds. Delta-9 tetrahydrocannabinol (THC) is the most well-known compound and its main psychoactive one1. Safety regulations dictate that consumers know exactly what they are getting when they take a medication. For example, their CBD-based medications should not contain traces of THC.
The cannabis industry greatly needs a tool to ensure the consistent extraction and isolation of compounds. In 2017, the cannabis industry was worth nearly $10 billion, and it is expected to grow $57 billion more in the next decade2. As legalization of medical cannabis expands, interest in CBD pharmaceuticals is likely to grow.
If compounds such as CBD are going to be used in pharmaceutical drugs, consistency is key to creating products that are safe for consumers.
CBD’s Potential
CBD is a non-psychoactive compound that makes up 40 percent of cannabis extracts1. It is great for medical applications because it does not interfere with motor or psychological function. Researchers have found it particularly effective for managing cancer pain, spasticity in multiple sclerosis, and specific forms of epilepsy3.

Other compounds derived from cannabis, such as cannabichromene (CBC) and cannabigerol (CBG), may also be beneficial compounds with medical applications. CBC is known to block pain and inflammation, and CBG is known for its use as a potential anti-cancer agent1.
Along with these compounds that provide medical benefits, there are psychoactive compounds that are used recreationally, such as THC.
“It will definitely be an advantage to have cannabis-based medications with clearly defined and constant contents of cannabinoids,” says Kirsten Müller-Vahl, a neurologist and psychiatrist at Hannover Medical School in Germany.
Creating a Standard Through Centrifugal Partition Chromatography
To obtain purified compounds from cannabis, researchers need to use technology that will extract the compounds from the plant.
Many manufacturers use some sort of chromatography technique to isolate compounds. Two popular methods are high performance liquid chromatography (HPLC) and flash chromatography. These methods have their places in the field, but they cannot be effectively and cost-efficiently scaled to isolate compounds. Instead, HPLC and flash chromatography may be better suited as analytical tools for studying the characteristics of the plant or extract. As cannabis has more than 400 chemical entities4, compound isolation is an important application.
This method is highly effective for achieving both high purity and recovery.Although molecules such as CBD can be synthesized in the lab, many companies would rather extract the compounds directly from the plant. Synthesized molecules do not result in a completely pure compound. The result, “is still a mixture of whatever cannabinoids are coming from a particular marijuana strain, which is highly variable,” says Brian Reid, chief scientific officer of ebbu, a company in Colorado that specializes in cannabis purification.
Currently, there is only one method available to researchers that completely allows them to isolate individual compounds: centrifugal partition chromatography (CPC).
The principle of CPC is similar to other liquid chromatography methods. It separates the chemical substances as the compounds in the mobile phase flow through and differentially interact with the stationary phase.
Where CPC and standard liquid chromatography differs is the nature of the stationary phase. In traditional chromatography methods, the stationary phase is made of silica or other solid particles, and the mobile phase is made of liquid. During CPC, the stationary phase is a liquid that is spun around or centrifuged to stay in place while the other liquid (mobile phase) moves through the disc. The two liquid phases, like oil and water, don’t mix. This method is highly effective for achieving both high purity and recovery. Chemists can isolate chemical components at 99 percent or higher purity with a 95 percent recovery rate5.
“CPC is ideal for ripping a single active ingredient out of a pretty complex mixture,” says Reid. “It’s the only chromatographic technique that does that well.”
The Need for Pure Compounds
High levels of purity and isolation are necessary for cannabis to be of true value in the pharmaceutical industry. Imagine relying on a medication to decrease your seizures, and it has a different effect every time. Sometimes there may be traces of psychoactive compounds. Sometimes there are too much or too little of the compound that halts your seizures. This is not a safe practice for consumers who rely on medications.“It’s hard to do studies on things you can’t control very well.”
Researchers working with cannabis desperately need a technology that can extract compounds with high purity rates. It is hard to run a study without knowing the precise amounts of compounds used. Reid uses a Gilson CPC 1000 system at ebbu for his cannabinoid research. With this technology, he can purify cannabinoids for his research and create reliable formulations. “Now that we have this methodology dialed in we can make various formulations —whether they’re water-soluble, sublingual, inhaled, you name it —with very precise ratios of cannabinoids and precise amounts of cannabinoids at the milligram level,” says Reid.
Kyle Geary, an internist at the University of Illinois at Chicago, is currently running a placebo-controlled trial of CBD capsules for Crohn’s disease. This consistent isolation is helpful for his research, as well. “Ideally, the perfect study would use something that is 100 percent CBD,” says Geary. “It’s hard to do studies on things you can’t control very well.”
The State of the Industry
While CBD is not considered a safe drug compound under federal law in the United States6, 17 states have recently passed laws that allow people to consume CBD for medical reasons7. Half of medicinal CBD users solely use the substance for treatment, a recent survey found8. As the industry quickly grows, it is crucial that consumer safety protocol keeps pace.
In June, the US Food and Drug Administration (FDA) approved the first drug that contains a purified drug substance from cannabis, Epidiolex9. Made from CBD, it is designed to treat Dravet Syndrome and Lennox-Gastaut syndrome, two rare forms of epilepsy. FDA Commissioner Scott Gottlieb said in the news release that although the FDA will work to support the development of high-quality cannabis-based products moving forward, “We are prepared to take action when we see the illegal marketing of CBD-containing products with serious, unproven medical claims. Marketing unapproved products, with uncertain dosages and formulations can keep patients from accessing appropriate, recognized therapies to treat serious and even fatal diseases.”
The industry should be prepared to implement protocols to ensure the quality of their CBD-based products. The FDA has issued warnings in recent years that some cannabinoid products it has tested do not contain the CBD levels their makers claim, and consumers should be wary of such products10. It’s hard to know when or if the FDA will begin regulating CBD-based pharmaceuticals. However, for pharma companies serious about their reputation, there is only one isolation method that creates reliable product quality: CPC.

Water is essential for life and it is an important part of agriculture and food manufacturing. Water has many uses in the cannabis industry. Among the most common uses are irrigation, ingredient/product processing and cleaning processes.
Water can be the carrier of pathogenic microorganisms and chemicals that can be transferred to food through agriculture and manufacturing practices. Poor quality water may have a negative impact in food processing and potentially on public health. Therefore, development and implementation of risk management plans that ensure the safety of water through the controls of hazardous constituents is essential to maintain the safety of agricultural and manufactured food or cannabis products.
Chemicals can enter the water stream through several sources such as storm water, direct discharge into fields and city water treatment plans.Although there no current regulations regarding the water used in cannabis cultivation and processing, it is highly recommended that the industry uses potable water as standard practice. Potable water is water that is safe for drinking and therefore for use in agriculture and food manufacturing. In the United States, the Environmental Protection Agency (EPA) sets the standards for water systems under the Safe Drinking Water Act (SDWA.)The regulations include the mandatory levels defined as Maximum Contaminant Levels (MCLs) for each contaminant that can be found in water. Federal Drinking Water Standards are organized into six groups: Microorganisms, Disinfectants, Disinfection Byproducts, Inorganic Chemicals, Organic Chemicals and Radionuclides. The agriculture and food manufacturing industry use the SDWA as a standard to determine water potability. Therefore, water testing forms part of their routine programs. Sampling points for water sources are identified, and samples are taken and sent to a reputable laboratory to determine its quality and safety.

Determining the safety of the water through microbiological testing is very important. Pathogens of concern such as E. coli, Salmonella, Cryptosporidium parvum and Cyclospora sp. can be transmitted to food through water. These pathogens have been known to be lethal to humans, especially when a consumer’s immune system is compromised (e.g. cancer patients, elderly, etc.) If your water source is well, the local state agency may come to your facility and test the water regularly for indicator organisms such as coliforms. If the levels are outside the limit, a warning will be given to your company. If your water source is the city, regular testing at the facility for indicator microorganisms is recommended. In each case, an action plan must be in place if results are unfavorable to ensure that only potable water is used in the operations.
Chemical Testing (Disinfectants, Disinfection Byproducts, Inorganic Chemicals, Organic Chemicals and Radionuclides)
Chemicals can enter the water stream through several sources such as storm water, direct discharge into fields and city water treatment plans. Although, there are several regulations governing the discharge of chemicals into storm water, fields and even into city water treatment plants, it is important that you test your incoming water for these chemicals on a regular basis. In addition, it is important that a risk assessment of your water source is conducted since you may be at a higher risk for certain components that require testing. For example, if your manufacturing facility is near an agricultural area, pesticides may enter the surface water (lakes, streams, and rivers) or the aquifer (ground water) through absorption into the ground or pollution. In this case, you may be at higher risk for Tetrahalomethanes (THMs), which are a byproduct of pesticides. Therefore, you should increase the testing for these components in comparison to other less likely to occur chemicals in this situation. Also, if your agriculture operation is near a nuclear plant, then radionuclides may become a higher risk than any of the other components.
Finally, in addition to the implementation of risk management plans to ensure the safety of water, it is highly recommended that companies working in food manufacturing facilities become familiar with their water source to ensure adequate supply to carry on their operations, which is one of the requirements under the 21 CFR 117. Subpart B – Current Good Manufacturing Practices (cGMPs) for food manufacturers under the Preventive Controls for Human Foods Rule that was enacted under the Food Safety Modernization Act in 2015. Also, adequate supply is part of the Good Agricultural Practices (GAP) The EPA has created a program that allows you to conduct a risk assessment on your water source. This program is called Source Water Protection. It has six steps that are followed to develop a plan that not only protect sourcing but also ensures safety by identifying threats for the water supply. These six steps are:
Delineate the Source Water Protection Area (SWPA): In this step a map of the land area that could contribute pollutants to the water is created. States are required to create these maps, so you should check with local and/or state offices for these.
Inventory known and potential sources of contamination: Operations within the area may contribute contaminants into the water source. States usually delineates these operations in their maps as part of their efforts to ensure public safety. Some examples of operations that may contribute to contaminants into the water are: landfill, mining operations, nuclear plants, residential septic systems, golf courses, etc. When looking at these maps, be sure that you verify the identified sources by conducting your own survey. Some agencies may not have the resources to update the maps on a regular basis.
Determine the susceptibility of the Public Water Source (PWS) to contaminate sources or activities within the SWPA: This is basically a risk assessment. In here you will characterize the risk based on the severity of the threat and the likelihood of the source water contamination. There are risk matrices that are used as tools for this purpose.
Notify the public about threats identified in the contaminant source inventory and what they mean to the PWS: Create a communication plan to make the State and local agencies aware of any findings or accidents in your operation that may lead to contamination of the PWS.
Implement management measures to prevent, reduce or eliminate risks to your water supply: Once risks are characterized, a plan must be developed and implemented to keep risks under control and ensure the safety of your water.
Develop contingency planning strategies that address water supply contamination or service interruption emergencies: OSHA requires you to have an Emergency Preparedness Plan (EPP). This plans outlines what to do in case of an emergency to ensure the safety of the people working in the operation and the continuity of the business. This same approach should be taken when it comes to water supply. The main questions to ask are: a) What would we do if we find out the water has been contaminated? b) What plan is in place to keep the business running while ensure the safety of the products? c) How can we get the operation back up and running on site once the water source is re-stablished?
The main goal of all these programs is having safe water for the operations while keeping continuity of the business in case of water contamination.
