According to a press release, last week GW Pharmaceuticals’ drug Epidiolex received a positive FDA panel review, which is an encouraging and important step towards getting the drug approved by the U.S. Food and Drug Administration and on the market in the United States. Epidiolex is an anti-epilepsy drug, taken in a syrup form, with the main active ingredient being cannabidiol (CBD), and less than 0.1 % THC.
The drug is targeted to treat Dravet syndrome (DS) and Lennox-Gastaut syndrome (LGS) a rare early-onset type of epilepsy found in children, according to Reuters. FDA staff said the drug “reduces seizure frequency in patients with drug-resistant LGS or DS while maintaining a predictable and manageable safety profile.”
GW Pharmaceuticals, founded in 1998 and based in London, is a biopharmaceutical company that has made headlines previously for developing cannabis-derived drugs. Sativex, one of the first drugs they developed, is derived from cannabis, but was not approved by the FDA. It is however available in other parts of the world, such as the EU, Israel and Canada.
If Epidiolex actually gets approval by the FDA, it will be the first-ever cannabis-derived drug available via prescription in all of the United States. According to Justin Gover, chief executive officer of GW Pharmaceuticals, this is a momentous breakthrough for the company. “We are pleased by the Advisory Committee’s unanimous recommendation to approve Epidiolex, which would provide an important treatment option for patients with LGS and Dravet syndrome, two of the most severe and treatment-resistant forms of epilepsy,” says Gover “This favorable outcome marks an important milestone in our company’s unwavering commitment to address the significant unmet need for patients with LGS and Dravet syndrome and our resolve to study Epidiolex under the highest research and manufacturing standards. We look forward to our ongoing discussions with the FDA as it continues to review the Epidiolex NDA.”
According to the GW press release, the Peripheral and Central Nervous System Drugs Advisory Committee of the FDA unanimously recommended supporting the approval of the New Drug Application (NDA) for the drug. That advisory committee is sort of like an independent panel; their unanimous vote doesn’t necessarily mean the drug will get approved, but the FDA takes their decision into consideration when approving new drugs. So this panel recommendation is certainly a good sign and shows this drug could potentially be on the path to FDA approval.
Many physicians today treat their patients with cannabidiol (CBD, Figure 1), a cannabinoid found in cannabis. CBD is more efficacious over traditional medications, and unlike delta-9 tetrahydrocannbinol (THC), the main psychoactive compound in cannabis, CBD has no psychoactive effects. Researchers have found CBD to be an effective treatment for conditions such as cancer pain, spasticity in multiple sclerosis, and Dravet Syndrome, a form of epilepsy.
Figure 1. The structure of cannabidiol, one of 400 active compounds found in cannabis.
Most manufacturers use chromatography techniques such as high performance liquid chromatography (HPLC) or flash chromatography to isolate compounds from natural product extracts. While these methods are effective for other applications, they are not, however, ideal for CBD isolate production. Crude cannabis oil contains some 400 potentially active compounds and requires pre-treatment prior to traditional chromatography purification. Both HPLC and flash chromatography also require silica resin, an expensive consumable that must be replaced once it is contaminated due to irreversible absorption of compounds from the cannabis extract. All of these factors limit the production capacity for CBD manufacturers.
Additionally, these chromatography methods use large quantities of solvents to elute natural compounds, which negatively impacts the environment.
A Superior Chromatography Method
Centrifugal partition chromatography (CPC) is an alternative chromatography method that can help commercial CBD manufacturers produce greater quantities of pure CBD more quickly and cleanly, using fewer materials and generating less toxic waste. CPC is a highly scalable CBD production process that is environmentally and economically sustainable.
The mechanics of a CPC run are analogous to the mechanics of a standard elution using a traditional chromatography column. While HPLC, for instance, involves eluting cannabis oil through a resin-packed chromatography column, CPC instead elutes the oil through a series of cells embedded into a stack of rotating disks. These cells contain a liquid stationary phase composed of a commonly used fluid such as water, methanol, or heptane, which is held in place by a centrifugal force. A liquid mobile phase migrates from cell to cell as the stacked disks spin. Compounds with greater affinity to the mobile phase are not retained by the stationary phase and pass through the column faster, whereas compounds with a greater affinity to the stationary phase are retained and pass through the column slower, thereby distributing themselves in separate cells (Figure 2).
Figure 2. How CPC isolates compounds from complex, natural mixtures. As the column spins, the mobile phase (yellow) moves through each cell in series. The compounds in the mobile phase (A, B, and C) diffuse into the stationary phase (blue) at different rates according to their relative affinities for the two phases.
A chemist can choose a biphasic solvent system that will optimize the separation of a target compound such as CBD to extract relatively pure CBD from a cannabis extract in one step. In one small-scale study, researchers injected five grams of crude cannabis oil low in CBD content into a CPC system and obtained 205 milligrams of over 95% pure CBD in 10 minutes.
Using a liquid stationary phase instead of silica imbues CPC with several time and cost benefits. Because natural products such as raw cannabis extract adhere to silica, traditional chromatography columns must be replaced every few weeks. On the other hand, a chemist can simply rinse out the columns in CPC and reuse them. Also, unlike silica columns, liquid solvents such as heptane used in CPC methods can be distilled with a rotary evaporator and recycled, reducing costs.
Environmental Advantages of CPC
The solvents used in chromatography, such as methanol and acetonitrile, are toxic to both humans and the environment. Many environmentally-conscious companies have attempted to replace these toxic solvents with greener alternatives, but these may come with drawbacks. The standard, toxic solvents are so common because they are integral for optimizing purity. Replacing a solvent with an alternative could, therefore, diminish purity and yield. Consequently, a chemist may need to perform additional steps to achieve the same quality and quantity achievable with a toxic solvent. This produces more waste, offsetting the original intent of using the green solvent.
CPC uses the same solvents as traditional chromatography, but it uses them in smaller quantities. Furthermore, as previously mentioned, these solvents can be reused. Hence, the method is effective, more environmentally-friendly, andeconomically feasible.
CPC’s Value in CBD Production
As manufacturers seek to produce larger quantities of pure CBD to meet the demand of patients and physicians, they will need to integrate CPC into their purification workflows. Since CPC produces a relativelyduct on a larger scale, it is equipped to handle the high-volume needs of a large manufacturer. Additionally, because it extracts more CBD from a given volume of raw cannabis extract, and does not use costly silica or require multiple replacement columns, CPC also makes the process of industrial-scale CBD production economically sustainable. Since it also uses significantly less solvent than traditional chromatography, CPC makes it financially feasible to make the process of producing CBD more environmentally-friendly.
The International Cannabis Business Conference (ICBC) in Berlin is now officially over. The speeches have been made, the parties have been attended. The hard-working crew behind it all has wrapped up, checked out and is off to Vancouver. And most of all, the marathon of meetings and deal discussions that were the mark of this budding and certainly by now established market are done. Even if there are still details to be ironed out in all the new business in the coming months.
As always, the dilemma for conference attendees was how to spend the limited time in this concentrated cannabis gathering. With all of the networking and excitement, people still wanted to hear the experts who spoke on topics ranging from cannabis financing to actually doing business in Germany to new medical advances. Traffic in the expo section was also heavy, as attendees visited the wide range of vendors. Producers and distributors of both plant and derived product were present, along with vape companies brave enough to compete with Storz and Bickel on their own turf, various tech solutions and of course, international consultants.
As the dust clears and the contracts get signed, what are the takeaways from the second edition of the ICBC in Berlin?
Germany Is Going Green
The simplest takeaway? The ICBC Berlin is not a market to be missed in the future for the global cannabis executive. Even if you are an American firm (and for the most part still largely excluded from a rapidly expanding worldwide trade that is establishing itself now with authority), you need to be here. The contacts you make are global, and you do not want to be left out. For foreign investors interested in this market, it is a must. For everyone else, this is a meet and greet, not to mention education, barnone. The German medical and even prosumer CBD market is attracting the world.
Yes, there have been ups and downs even in the last three weeks that include the crashing of the German bid along with news stateside that the Trump Administration is going to hang Jeff Sessions out to dry for Russia with his latest “Make American States Great For Cannabis Again” contortion.

But here on the other side of the Atlantic, it is clear that the federal cannabinoid horse has left the barn. There are now rumorsfloating that the bid is not yet entirely dead (now apparently in a legal purgatory of appeals and even potentially “bid amendments”) that nobody is willing to go on record to discuss. Beyond that, however, as was clear from the frenzied deal-makingon the floor and off it at the ICBC, the market is open, distributors are finding new channels to move product, and patients demanding access are not leaving the streets.
Far from it. In fact, the budding nascent umbrella national non-profit campaign designed to open access for patients and educate doctors, The German Patients Roundtable, had a huge second meeting during the conference, with both German and international attendees from countries including Israel and South Africa.
The CBD and THC genie cannot be stuffed back into the local bottle. And everyone knows it. This is federal medical reform, and even better, covered under German national public health insurance. Despite the hiccups and challenges that still remain, this is open blue water for a medical market that has never existed anywhere to date.
Anyone with a GMP facility, Euro cleared export rights and crop or product ready to ship will be welcome here in a market that at this point, cannot get enough plant or oil. Edibles are still a to-come discussion.
To the extent that this is also negative, it is very clear that the market is still highly inefficient. Producers who do have productare not being found by those on the ground who want to sell it to patients. That will also begin to change. But for now, many on the ground are playing a digitalized Rolodex game of “who do you know” that still consists of personal emails between conference-met colleagues if not LinkedIn contacts and impromptu (and freebie) favors. Those who hope to gain an income merely by connecting the source of product and outlets the old fashioned way are also about to be left in the dust by a market that will not be held back and activist businesses who are eyeing both the United States and Canada right now (if not Israel and Australia), and translating all of that into both euros and German.
It is also very clear that the savvy Germans who were largely left out of the bid proceedings last time do not mean to sit this party out – and are angling to get into the game however they can. This is taking some interesting forms, but processing and testing are going to be huge issues of the market here for a long time to come. And so is home-grown, high-quality CBD. The German government is even offering tax credits for growing certain kinds of hempright now. Sound familiar Kentucky?
Trends and Takeaways
It is not just the Canadians who are going to get market share. The Canadian LPs are still in a good position to dominate the early market but it is clear that there is still room for others to enter. Whether the government allows an appeal of the court’s decision to hold up, there is a quick bid “redo” for the top 10 finalists, or a second bid, the market has now arrived and is in its second year.
Marguerite Arnold presents on the impact of blockchain on the cannabis industry
CBD is going to be an important path to other kinds of provision and cultivation. Despite the widespread misconceptions about Germany being a “CBD only” market (it is not), it is clear that a consumer CBD only strategy will be an interesting path into the market here but not one for the faint of heart. The Canadian companies in particular are beginning to move into the realm of big pharma (their market caps certainly are). But it is also clear that more local competition is hip to the same. And as a result, even this part of the market will be a highly competitive one.
German firms are first at this gate, beyond the big Canadian LPs, but they are not the only ones now in the market. See Dutch, Austrian and Swiss firms, many with pharmaceutical company credits and market entry already under their belt. Not to mention producers from both Greece and the Baltics. Everyone on the import side is eyeing the opening market and stalled bid as a fantastic opportunity. Look for products from these locales as testing and certification protocols become more effective.
Central to all of these developments? The conference is theplacefor the global cannabis industry to meet and get to know one another, put together by Alex Rogers and a seasoned, international team behind the ICBC.
BioMauris, LLC became the 5th company in the United States to win a state contract for a seed-to-sale platform today. BioMauris is a technology company that manages product tracking, fulfillment and distribution with a focus on the healthcare market. According to a press release, the company announced today that the state of Iowa selected BioMauris to manage their tracking system for the medical cannabidiol (CBD) program.
That program’s contract includes inventory tracking, medical cannabidiol sales and patient and caregiver registration. In 2014, Iowa’s Medical Cannabidiol Act was signed into law. Three years later, in May of 2017, Governor Terry Branstad expanded the state’s program, including manufacture and dispensing in the previous legislation. On December 1st, 2018, Iowa expects sales to begin and fully implement the program.
This is BioMauris’ first state contract in the cannabis industry. According to the press release, BioMauris bases their platform on Salesforce for point of sale, tracking, customer loyalty and distribution services in the healthcare sector. The company says they use Salesforce because it is extremely customizable and secure.
Erik Emerson, founder and president of Biomauris
According to Erik Emerson, founder and president of BioMauris, they’re poised to deliver on this front, given their experience in other industries. “Our team has extensive history in the pharmaceutical business, and therefore has a unique appreciation for data integrity and security,” says Emerson. “Additionally, we fundamentally believe the opportunity to track patient progress and associate the benefits received with the products used, is an incredible opportunity for the cannabis industry.” BioMauris has worked with clients on similar projects in the healthcare space for some time.
The company touts their platform as fully PCI-DSS and HIPAA compliant, allowing them to process payments and protect sensitive patient information. “Our patented technology, makes this not only possible, but simple for all users,” says Emerson. “We are excited to bring our product to the great state of Iowa and look forward to a long partnership with them. We believe strongly in what Iowa is attempting to do with their program and believe it is a perfect fit with our strategy for the cannabis industry.”

With legalization of cannabis for medicinal and adult use occurring rapidly at the state level, the industry is seeing a sharp increase in innovative technologies, particularly in the area of cannabis extraction. Companies are developing novel extraction methods that are capable of not only separating and recovering high yields of specific cannabinoids, but also removing harmful chemicals (such as pesticides) from the concentrate. While some extraction methods utilize solvents, such as hydrocarbons, the industry is starting to see a shift to completely non-solvent based techniques or environmentally friendly solvents that rely on, for example, CO2, heat and pressure to create a concentrate. The resulting cannabis concentrate can then be consumed directly, or infused in edibles, vape pens, topicals and other non-plant based consumption products. With companies continually seeking to improve existing extraction equipment, methods and products, it is critical for companies working in this area to secure their niche in the industry by protecting their intellectual property (IP).
Extraction can be an effective form of remediating contaminated cannabis
Comprehensive IP protection for a business can include obtaining patents for innovations, trademarks to establish brand protection of goods and services, copyrights to protect logos and original works, trade dress to protect product packaging, as well as a combination of trade secret and confidentiality agreements to protect proprietary information and company “know-how” from leaking into the hands of competitors. IP protection in the cannabis space presents unique challenges due to conflicting state and federal law, but for the most part is available to cannabis companies like any other company.
Federal trademark protection is currently one of the biggest challenges facing cannabis companies in the United States. A trademark or service mark is a word, phrase, symbol or design that distinguishes the source of goods or services of one company from another company. Registering a mark with the U.S. Patent and Trademark Office (USPTO) provides companies with nationwide protection against another company operating in the same space from also using the mark.
As many in the industry have come to discover, the USPTO currently will not grant a trademark or service mark on cannabis goods or services. According to the USPTO, since cannabis is illegal federally, marks on cannabis goods and services cannot satisfy the lawful use in commerce requirement of the Lanham Act, the statute governing federal trademark rights. Extraction companies that only manufacture cannabis-specific equipment or use cannabis-exclusive processes will likely be unable to obtain a federal trademark registration and will need to rely on state trademark registration, which provides protection only at the state-level. However, extractors may be able to obtain a federal trademark on their extraction machines and processes that can legitimately be applied to non-cannabis plants. Likewise, companies that sell cannabis-infused edibles may be able to obtain a federal trademark on a mark for non-cannabis containing edibles if that company has such a product line.
Some extraction companies may benefit from keeping their innovations a trade secretSince the USPTO will not grant marks on cannabis goods and services, a common misconception in the industry is that the USPTO will also not grant patents on cannabis inventions. But, in fact, the USPTO will grant patents on a seemingly endless range of new and nonobvious cannabis inventions, including the plant itself. (For more information on how breeders can patent their strains, see Alison J. Baldwin et al., Protecting Cannabis – Are Plant Patents Cool Now? Snippets, Vol. 15, Issue 4, Fall 2017, at 6). Unlike the Lanham Act, the patent statute does not prohibit illegal activity and states at 35 U.S.C. § 101 that a patent may be obtained for “any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof.”
For inventions related to extraction equipment, extraction processes, infused products and even methods of treatment with concentrated formulations, utility patents are available to companies. Utility patents offer broad protection because all aspects related to cannabis extraction could potentially be described and claimed in the same patent. Indeed, there are already a number of granted patents and published patent applications related to cannabis extraction. Recently, U.S. Patent No. 9,730,911 (the ‘911 patent), entitled “Cannabis extracts and methods of preparing and using same” that granted to United Cannabis Corp. covers various liquid cannabinoid formulations containing very high concentrations of tetrahydrocannabinolic acid (THCa), tetrahydrocannabinol (THC), cannabidiol (CBD), THCa and cannabidiolic acid, THC and CBD, and CBD, cannabinol (CBN), and THC. For example, claim 1 of the ‘911 patent recites:
A liquid cannabinoid formulation, wherein at least 95% of the total cannabinoids is tetrahydrocannabinolic acid (THCa).Properly crafted non-disclosure agreements can help further ensure that trade secrets remain a secret indefinitely.
Although the ‘911 patent only covers the formulations, United Cannabis Corp. has filed a continuation application that published as US2017/0360745 on methods for relieving symptoms associated with a variety of illnesses by administering one or more of the cannabinoid formulations claimed in the ‘911 patent. This continuation application contains the exact same information as the ‘911 patent and is an example of how the same information can be used to seek complete protection of an invention via multiple patents.
An example of a patent application directed to solvent-based extraction methods and equipment is found in US20130079531, entitled “Process for the Rapid Extraction of Active Ingredients from Herbal Materials.” Claim 1 of the originally filed application recites:
A method for the extraction of active ingredients from herbal material comprising: (i) introducing the herbal material to a non-polar or mildly polar solvent at or below a temperature of 10 degrees centigrade and (ii) rapidly separating the herbal material from the solvent after a latency period not to exceed 15 minutes.
Claim 12, covered any equipment designed to utilize the process defined in claim 1.
Although now abandoned, the claims of this application were not necessarily limited to cannabis, as the claims were directed to extracting active ingredients from “herbal materials.”
Other patents involve non-toxic extraction methods utilizing CO2, such as Bionorica Ethics GMBH’s U.S. Patent No. 8,895,078, entitled “Method for producing an extract from cannabis plant matter, containing a tetrahydrocannabinol and a cannabidiol and cannabis extracts.” This patent covers processes for producing cannabidiol from a primary extract from industrial hemp plant material.
There have also been patents granted to cannabis-infused products, such as U.S. Patent No. 9,888,703, entitled “Method for making coffee products containing cannabis ingredients.” Claim 1 of this patent recites:
A coffee pod consisting essentially of carbon dioxide extracted THC oil from cannabis, coffee beans and maltodextrin.
Despite the USPTO’s willingness to grant cannabis patents, there is an open question currently regarding whether they can be enforced in a federal court (the only courts that have jurisdiction to hear patent cases). However, since utility patents have a 20-year term, extractors are still wise to seek patent protection of the innovations now.
Another consideration in seeking patent protection for novel extraction methods and formulations is that the information becomes public knowledge once the patent application publishes. As this space becomes increasingly crowded, the ability to obtain broader patents will decline. Therefore, some extraction companies may benefit from keeping their innovations a trade secret, which means that the secret is not known to the public, properly maintained and creates economic value by way of being a secret. Properly crafted non-disclosure agreements can help further ensure that trade secrets remain a secret indefinitely.
Regardless of the IP strategy extractors choose, IP protection should be a primary consideration for companies in the cannabis industry to ensure the strongest protection possible both now and in the future.
Facing the same conundrum as police everywhere after the start of a medical market only this time with federal authorization, the head of the German police union has called for recreational use of cannabis to also be decriminalized.
On the first Monday of February, the head of the BDK – the Association of German Criminal Officers told The Bild (sort of like the New York Post but a national “tabloid” here) that his group, the largest organized union of German police officers, favoured a change in German cannabis laws. Andre Schulz argued that the current laws stigmatized those charged with minor amounts and created opportunities for “criminal careers to start.”
“The prohibition of cannabis has historically been seen as arbitrary and has not yet been implemented in an intelligent and effective manner,” says Schulz. “My prediction is that cannabis will not be banned for long in Germany.”
Why this sudden pronouncement? It is actually not all that sudden and has been long in the offing. One of the largest contingents at both the ICBC and the IACM last year (the biggest cannabis-focussed business and medical conferences in Germany) were police officers from California and Deutschland. And all were singing the same tune.
André Schulz, chairman of the BDK
However beyond a realistic assessment of changing political reality, there are actually several other concrete reasons for not only the statement but the timing of it. In a country where patients can now pick up bud cannabis from the local apotheke (which is that easy for some, although it is still hard for most), the police have the unappetizing prospect of potentially arresting patients. On top of that, the idea of someone being arrested for CBD flower (rather than THC) gives the German polizei plenty of pause. Not to mention that they face this possibility at a time when many of them potentially could be patients themselves (or their families). The idea of arresting an activist in this situation is also one the police do not relish. Legalization rallies here get formal police protection when they march. Ask the average beat cop what they think about cannabis legalization and they tend to roll their eyes.
Then there is this: In stark contrast to the wars over prescribing medical cannabis at a state level in California in the late 90’s, here in Germany, there is a cultural commitment to the concept of sick people having a moral and civil right to obtain the medication they require. The idea of the police arresting them in the process of obtaining the same or because they might be recreational users, is as antithetic to core German sensibilities as the concept of Donald Trump as U.S. President. So is the idea of branding someone a “criminal” if not “drug user” for possession of a drug that is now used as medicine in Germany.
As has been rumoured for some time now, one of the few things that all political parties in Berlin can agree on is a change on the current cannabis laws.As a result, the very idea of both arresting the sick or labelling someone for the rest of their life with a police record for a drug “crime” that nobody considers as such anymore, causes a shock to the system. In many ways, German culture is far more conservative than the U.S. On another, there is a deeply humanistic, liberal strain to German life that also allows nudity, alternative healthcare and lifestyles to flourish (and not just all in Berlin). The current situation over cannabis, in other words, is becoming a political and legal embarrassment even to the beat officers who have to implement such laws.
And then of course there is this: One of the country’s top judges, Andreas Müller, a man well-known to the senior level of BDK, has recently written a book about the horrible situation that faces his own brother because of drug laws in Germany called “Kiffen und Kriminalität.”
Cannabis also falls into this crevice of cultural questioning if not the national zeitgeist of the moment, in multiple ways. It is, beyond the stigma, a natural medicine that is now federally recognized as such and one that the statutory health insurers (public healthcare) is required to cover. No matter that only 64% of submitted rezepts have been formally approved 11 months into Germany’s foray into this world. There are doctors writing them. And there are insurers picking up the tab.
It also means that there are at least 10,000 legal medical cannabis patients that der polizei have no wish to bother. And 10,000 German patients, who look the same as anyone else, are already too many legal users for current laws to stay in place.
Decriminalization, Cultivation & Changing Culture
There are some who say that Europe is “backwards” if not slower than the United States. Certainly those who experience German culture as Auslanders are struck by the procedural requirements of everyday life. Things do move slower here.
However when things do move, they are determinative shifts. Right now, it is impossible to live in the country and not be aware that Kiffen – a slang term for pot auf Deutsch – is legalizing in the U.S., Canada, the rest of Europe and of course other places. Further, Germans with their distrust of bureaucracy and authority and certainly currently rebellious mood, are looking to a way forward for the country in a sea of uncertainty both locally and regionally not to mention globally on any issue, no matter how “symbolic.”
As has been rumoured for some time now, one of the few things that all political parties in Berlin can agree on is a change on the current cannabis laws. The idea of decriminalization, now suggested by one of the country’s top cops, is a natural solution to political deadlock, if not a changing society.
The idea that other countries are also moving on this topic, from the now Brexiting UK to France next door, not to mention all the cultivation focused reform in many European countries, seems to indicate that decriminalization and even recreational reform are coming and now officially on the schedule, and not just to Germany but the entire continent.
As many US States and Canadian provinces approach legalization of cannabis, the question of regulatory oversight has become a pressing issue. While public awareness is mainly focused on issues like age restrictions and impaired driving, there is another practical question to consider: should cannabis be treated as a drug or a food product when it comes to safety? In the US, FDA governs both food and drugs, but in Canada, drugs are regulated by Health Canada while food products are regulated under the CFIA.There are many food safety hazards associated with cannabis production and distribution that could put the public at risk, but are not yet adequately controlled
Of course, there are common issues like dosage and potency that pharmaceutical companies typically worry about as the industry is moving to classifying its products in terms of percentage of chemical composition (THC, CBD, etc. in a strain), much as we categorize alcohol products by the percentage of alcohol. However, with the exception of topical creams and ointments, many cannabis products are actually food products. Even the herb itself can be brewed into teas, added to baked goods or made into cannabis-infused butters, oils, capsules and tinctures.
As more people gain access to and ingest cannabis products, it’s only a matter of time before food safety becomes a primary concern for producers and regulators. So when it comes to food safety, what do growers, manufacturers and distributors need to consider? The fact is, it’s not that different from other food products. There are many food safety hazards associated with cannabis production and distribution that could put the public at risk, but are not yet adequately controlled. Continue reading below for the top four safety hazards for the cannabis industry and learn how to receive free HACCP plans to help control these hazards.
Aflatoxins on Cannabis Bud
Just like any other agricultural product, improper growing conditions, handling and storage can result in mold growth, which produce aflatoxins that can cause liver cancer and other serious health problems. During storage, the danger is humidity; humidity must be monitored in storage rooms twice a day and the meter must be calibrated every month. During transportation, it is important to monitor and record temperatures in trucks. Trucks should also be cleaned weekly or as required. Products received at a cannabis facilities should be tested upon receiving and contaminated products must always be rejected, segregated and disposed of safely.

Chemical Residues on Cannabis Plants
Chemical residues can be introduced at several points during the production and storage process. During growing, every facility should follow instructions for applying fertilizers and pesticides to crops. This includes waiting for a sufficient amount of time before harvesting. When fertilizer is being applied, signs must be posted. After cannabis products have been harvested, chemical controls must be in place. All chemicals should be labelled and kept in contained chemical storage when not in use to prevent contamination. Only food-grade chemicals (e.g. cleaners, sanitizers) should be used during curing, drying, trimming and storage.
Without a comprehensive food safety program, problems will inevitably arise.There is also a risk of excessive concentration of chemicals in the washing tank. As such, chemical concentrations must be monitored for. In general, water (obviously essential for the growing process) also carries risks of pathogenic bacteria like staphylococcus aureus or salmonella. For this reason, city water (which is closely controlled in most municipalities) should be used with an annual report and review. Facilities that use well water must test frequently and water samples must be tested every three months regardless.
Pathogenic Contamination from Pest Infestations
Insects, rodents and other pests spread disease. In order to prevent infestations, a pest control program must be implemented, with traps checked monthly by a qualified contractor and verified by a designated employee. It is also necessary to have a building procedure (particularly during drying), which includes a monthly inspection, with no holes or gaps allowed. No product should leave the facility uncovered to prevent fecal matter and other hazards from coming into contact with the product. Contamination can also occur during storage on pallets, so pallets must be inspected for punctures in packaging material.
Furthermore, even the best controlled facility can fall victim to the shortcomings of their suppliers. Procedures must be in place to ensure that suppliers are complying with pest and building control procedures, among others. Certifications should be acquired and tracked upon renewal.
Pathogenic Contamination Due to Improper Employee Handling
Employee training is key for any food facility. When employees are handling products, the risk of cross-contamination is highest. Facilities must have GMP and personnel hygiene policies in place, with training conducted upon hiring and refreshed monthly. Employees must be encouraged to stay home when sick and instructed to wear proper attire (gloves, hair nets, etc.), while glass, jewelry and outside food must not be allowed inside the facility. Tools used during harvesting and other stages may also carry microorganisms if standard cleaning procedures are not in place and implemented correctly by employees.
As the cannabis industry grows, and regulatory bodies like the FDA and CFIA look to protect public safety, we expect that more attention will be paid to other food safety issues like packaging safety (of inks and labels), allergen control and others. In the production of extracts, for example, non-food safe solvents could be used or extracts can be mixed with ingredients that have expiration dates, like coconut oil. There is one area in which the cannabis industry may lead the way, however. More and more often, risks of food terrorism, fraud and intentional adulteration are gripping the food industry as the global food chain becomes increasingly complex. It’s safe to say that security at cannabis facilities is probably unparalleled.
All of this shows that cannabis products, especially edibles (and that includes capsules and tinctures), should be treated the same as other food products simply because they have the same kinds of hazards. Without a comprehensive food safety program (that includes a plan, procedures, training, monitoring and verification), problems will inevitably arise.
Rebel Coast Winery announced this week the launch of the world’s first cannabis-infused, alcohol-removed wine. The company’s THC-infused Sauvignon Blanc, available only in California, will hit dispensary shelves in 2018.

According to the press release, they plan to be fully compliant with California’s new regulations for the cannabis industry, hence the lack of alcohol in the product, which is a requirement under the state’s new manufacturing rules. “Rebel Coast’s grapes are grown in Sonoma County – California’s wine capital – and fermented through a traditional winemaking process,” reads the press release. “Rebel Coast removes the wine’s alcohol and infuses each bottle of its premium Sauvignon Blanc with 16 milligrams of organic tetrahydrocannabinol (THC)…” In addition to the THC infusion, they also add terpenes to the final product, giving it the cannabis fragrance.
According to Alex Howe, co-founder of Rebel Coast, the winery is in Sonoma, but they’re waiting to see where they’ll be licensed to extract, infuse and package the final product. “The winery is in Sonoma, we make the wine, and remove the alcohol there,” says Howe. “We’re currently waiting for licensing transfer approval in two locations, one in San Bernardino, the other West Sacramento, and exploring an option to infuse in San Benito County with a currently licensed location.” They plan to co-package under a third party license and seek a Type N license for extraction with non-volatile solvents.
Rebel Coast has partnered with a fully licensed outdoor grower, and is looking for an extractor that will be able to handle their volume needs. With regard to their infusion and extraction process, Howe says they combine clear distillate with a surfactant to make the THC liquid soluble and fast acting.
He expects the full infusion and packaging operations to be up and running by early 2018. “The San Bernardino and West Sacramento locations were previously licensed for infusion, packaging, and manufacturing, but with purchase of the building, the change in ownership has caused us to wait for the license to change ownerships too.”
“We’ve continued our disruptive approach to craft the world’s first cannabis-infused, alcohol-free wine,” says Chip Forsythe, co-founder and chief executive officer of Rebel Coast. “We wanted to excite the rebellious spirit in Americans through innovation, so we took two world-class California products – marijuana and wine – and created a proprietary process that resulted in a delicious, crisp and elegantly crafted Sauvignon Blanc that’s teed up to be a game changer for the wine and cannabis industries.”
They plan to start shipping product in early 2018, as well as distribute to over 500 dispensaries throughout the state, via Green Reef Distributing, a licensed cannabis distributor that represents wine and spirit accounts for other CBD products. Later in 2018, Rebel Coast plans on rolling out cannabis-infused Rosé and champagne, as well as CBD-infused wines. In the press release the company teases their products will be available in other legal states in the coming months.
Next Frontier Biosciences announced the launch of their new product line, Verra Wellness, in the Colorado market this week. The products are designed with relatively new concepts for the cannabis market, including nasal, sublingual and topical administration.
The company claims their product is the first-ever cannabis nasal mist. Co-founded by biotech executives Marc Graboyes and Dr. Paul Johnson, Ph.D, Next Frontier Biosciences is developing this product line with three formulations, each with a different ratio of THC and CBD. According to a press release, Next Frontier Biosciences is focused on developing cannabis products with these new drug delivery methods, and even offering a microdosing option.
“We believe that leveraging science and research is the key to optimizing product development,” says Dr. Johnson, one of the co-founders. “With the introduction of our Verra Wellness line of products, we are reshaping the cannabis industry by offering trusted products that provide uniform composition, formulation and dosing in highly consistent modes of administration.”
Their topical salves in the Verra Wellness product line are “designed to permeate skin and muscle tissue deeply without penetrating the blood stream or causing psychoactive effects,” reads a press release. In addition to the nasal mist and topical salve, they also launched a sublingual spray.

According to Marc Graboyes, chief executive officer and co-founder of Next Frontier Biosciences, drug delivery mechanisms like a nasal mist are superior to smoking, vaporizing and edible administration. “Nasal administration is among the most effective delivery technologies due to the extensive vascularization and large surface area of the nasal cavity, allowing for rapid uptake and reliable results,” says Graboyes. “The cannabis nasal mist is a novel technology that other brands have not yet tapped into.”
He says this drug delivery mechanism is efficient, fast acting and a healthy alternative to smoking. “For many, nasal delivery is a desirable alternative delivery mechanism because it does not present the health risks associated with smoking,” says Graboyes. “In addition, as previously mentioned, the large surface area of the nasal cavity permits high drug absorption, and the fine-mist sprayer allows for accurate, consistent dosing and an excellent safety profile. Further, nasal delivery avoids first-pass metabolism by the liver, where a large fraction of orally delivered cannabinoids are inactivated.”
While the Verra Wellness product line is available in Colorado starting this week, the company has plans to expand into a number of other states as well. “We are executing a multi-state expansion, with plans to move into the California, Oregon, Washington and Nevada markets in the coming year,” says Graboyes.
On November 1st, the U.S. Food and Drug Administration (FDA) published a press release addressing warning letters issued to four companies. The warning letters, sent to companies marketing cannabidiol (CBD) products with therapeutic claims, cites unsubstantiated claims about their products’ ability to treat or cure cancer and other diseases.

According to the press release, the four companies that received warning letters are Greenroads Health, Natural Alchemist, That’s Natural! Marketing and Consulting, and Stanley Brothers Social Enterprises LLC. The press release called their marketing campaigns “deceptive” for “unproven treatments.” Here is the letter they sent to Greenroads Health.
“As part of the U.S. Food and Drug Administration’s ongoing efforts to protect consumers from health fraud, the agency today issued warning letters to four companies illegally selling products online that claim to prevent, diagnose, treat, or cure cancer without evidence to support these outcomes,” reads the FDA statement. “Selling these unapproved products with unsubstantiated therapeutic claims is not only a violation of the Federal Food, Drug and Cosmetic Act, but also can put patients at risk as these products have not been proven to be safe or effective.”
According to the press release, the FDA has issued ninety warning letters in the past ten years, with around twelve this year, to companies making fraudulent claims about cancer therapies. Here are some examples of claims made by companies that the FDA took issue with:
“Combats tumor and cancer cells;”
“CBD makes cancer cells commit ‘suicide’ without killing other cells;”
“CBD … [has] anti-proliferative properties that inhibit cell division and growth in certain types of cancer, not allowing the tumor to grow;” and
“Non-psychoactive cannabinoids like CBD (cannabidiol) may be effective in treating tumors from cancer – including breast cancer.”
“Substances that contain components of marijuana will be treated like any other products that make unproven claims to shrink cancer tumors,” says FDA Commissioner Scott Gottlieb, M.D. “We don’t let companies market products that deliberately prey on sick people with baseless claims that their substance can shrink or cure cancer and we’re not going to look the other way on enforcing these principles when it comes to marijuana-containing products. There are a growing number of effective therapies for many cancers. When people are allowed to illegally market agents that deliver no established benefit they may steer patients away from products that have proven, anti-tumor effects that could extend lives.”

The drug is targeted to treat Dravet syndrome (DS) and Lennox-Gastaut syndrome (LGS) a rare early-onset type of epilepsy found in children, according to Reuters. FDA staff said the drug “reduces seizure frequency in patients with drug-resistant LGS or DS while maintaining a predictable and manageable safety profile.”
If Epidiolex actually gets approval by the FDA, it will be the first-ever cannabis-derived drug available via prescription in all of the United States. According to Justin Gover, chief executive officer of GW Pharmaceuticals, this is a momentous breakthrough for the company. “We are pleased by the Advisory Committee’s unanimous recommendation to approve Epidiolex, which would provide an important treatment option for patients with LGS and Dravet syndrome, two of the most severe and treatment-resistant forms of epilepsy,” says Gover “This favorable outcome marks an important milestone in our company’s unwavering commitment to address the significant unmet need for patients with LGS and Dravet syndrome and our resolve to study Epidiolex under the highest research and manufacturing standards. We look forward to our ongoing discussions with the FDA as it continues to review the Epidiolex NDA.”
