The success of reputable cannabis and CBD brands has inspired an influx of inexperienced and disreputable competitors in the market. These so-called “bad actors” in CBD advertise products that are not manufactured under current Good Manufacturing Practices (cGMP), which help to ensure that all products are consistently produced and controlled according to specified quality standards. cGMP helps guard against risks of adulteration, cross-contamination and mislabeling to guarantee product quality, safety and efficacy.

CBD products without cGMP regulations are often inaccurately labeled and deceiving to consumers. In fact, in a test of over 100 CBD products available online and at retail locations, Johns Hopkins Medicine found significant evidence of inaccurate, misleading labeling of CBD content. The prevalence of such brands not only reduces consumer confidence in CBD but also limits the growth of the sector as a whole. Fortunately, CBD consumers and retailers can easily discriminate between a well-tested, reputable brand and inferior bad actors with a few straightforward, minimum requirements to look out for when selecting a product.

Why are “bad actors” a problem for consumers and the industry?

Bad actors in CBD sell products that are not produced under cGMP conditions and are typically not tested by third-party laboratories to ensure identity, purity, quality, strength and composition. This means they are not verified for contaminants, impurities, label claims and product specifications. This frequently results in misleading advertising with inaccurate levels of cannabinoids or traces of compounds not found on the label, like THC. To combat this, the FDA issues warning letters to actors that market products allegedly containing CBD—many of which are found not to contain the claimed levels of CBD and are not approved for the treatment of any medical condition. Still, bad actors manage to slip through the cracks and deceive consumers.

Bad actors that put anything in a bottle and make unsubstantiated medical claims hurt the reputable operators that strive to create safe and high-quality products. It is easy for consumers to be drawn to CBD products with big medical claims and lower prices, only to be disappointed when the product does not produce the advertised results. Inaccurately labeled products may contain unexpected levels of cannabinoids, including ingredients that consumers may not intend to ingest, like Delta-9 or Delta-8 THC. Along with unexpected levels of THC, many CBD products available now are not as pure as advertised, with one in four products going untested for contaminants like microbial content, pesticides, or heavy metals.

Further, inaccurate labeling of products and their compounds also prevents consumers from establishing a baseline impact of CBD on their bodies, leaving them vulnerable to inconsistent future experiences. Such a poor experience can turn consumers off to the category as a whole, drawing their trust away from not only the bad actors but also the reliable, reputable brands on the market. The saturation of the market with these disreputable brands delegitimizes a category that has only just begun to break down the stigmas, creating stagnation rather than growth as consumers remain wary of low-quality products.

How can consumers identify bad actors in CBD?

There are several simple ways to identify a bad actor among CBD products and make certain that both consumers and retailers purchase quality, reliable and safe brands in legitimate sales channels. To start, consumers should avoid all CBD products that are marketed with unsubstantiated medical claims. This is a significant area of abuse, as brands that relate any form of CBD product to a disease state, like cancer, should not be trusted. The science to support such medical claims has not been completed, yet, product marketing is years ahead of the evidence to support such claims. Unsupported medical claims could also mislead consumers that may need more serious medical intervention.

Additionally, consumers must review the packaging, which should include nutrition information in the form of a supplement fact label. The label should include the serving size, number of servings per container, a list of all dietary ingredients in the product and the amount per serving of each ingredient. All labels should include a net quantity of contents, lot number or batch ID, the name and address of the manufacturer, and an expiration or manufacturing date. These signs of a reputable brand are easy to look for and can save consumers from the trouble of selecting the wrong CBD product.

What to look for when selecting a CBD product

With this in mind, products from reputable, tested brands can be identified by a few key factors. Reputable CBD companies are already compliant with the FDA regulations on nutritional supplements, including a nutritional or supplement fact panel on the packaging—just like vitamins. The information in this panel should include all the active cannabinoids in the product, both per serving and package. Clear potency labeling allows consumers to confidently select products that suit their needs and understand the baseline impact of CBD concentration on their bodies, thus helping them to tailor their experience with thoughtful product selection.

Reputable brands also include a convenient QR code on the packaging, linking the product to a certificate of analysis that details the testing results to demonstrate compliance with product standards and label claims. In terms of specific ingredients, consumers should be skeptical of high concentration levels of “flavor of the month” minor cannabinoids, which are often associated with unsubstantiated medical claims. Current scientific research has set its focus on major cannabinoids like CBD and Delta-9 THC, leaving additional research necessary for understanding minor cannabinoids. Minor cannabinoids are typically included in full spectrum products at concentrations found naturally in the cannabis plant, which is a safer approach to consuming CBD until more research is completed.

Consumers should not let the existence of unreliable, untrustworthy brands curtail their confidence in the CBD sector—there are many high-quality, safe and trusted brands on the market. With a knowledgeable and discerning eye, consumers and retailers can easily select top-quality CBD products that millions of consumers have found to improve many aspects of their health and well-being. Looking ahead, clear federal regulations for CBD products that require mandatory product registration, compliance with product labeling, packaging and cGMP will be crucial in weeding out bad actors and will allow compliant companies to gain consumer trust and responsibly grow the CBD category.

Centrifugal Partition Chromatography Paves the Way for Safer, More Standardized Cannabidiol Drugs

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.
