According to a press release published today, Emerald Scientific awarded PerkinElmer five badges for The Emerald Test, a bi-annual Inter-Laboratory Comparison and Proficiency Test (ILC/PT) program. Awarding the badges for Perkin Elmer’s instruments and testing methods affirms their ability to accurately detect pesticides, heavy metals, residual solvents, terpenes and potency in cannabis.
According to Greg Sears, vice president and general manager of Food, Chromatography & Mass Spectrometry, Discovery & Analytical Solutions at PerkinElmer, they are the only instrument manufacturer to receive all five accolades. “To date, PerkinElmer is the only solutions provider to successfully complete these five Emerald Scientific proficiency tests,” says Sears. “The badges underscore our instruments’ ability to help cannabis labs meet the highest standards available in the industry and effectively address their biggest pain point: Navigating diverse regulations without compromising turnaround time.”
The instruments used were PerkinElmer’s QSight 220 and 420 Triple Quad systems, which are originally designed for accurate and fast detection/identification of “pesticides, mycotoxins and emerging contaminants in complex food, cannabis and environmental samples,” reads the press release. They also used their ICP-MS, GC/MS and HPLC systems for the badges.
PerkinElmer says they developed a single LC/MS/MS method using their QSight Triple Quad systems, which helps labs test for pesticides and mycotoxins under strict regulations in states like California and Oregon. They performed studies that also confirm their instruments can help meet Canada’s testing requirements, which set action limits nearly 10 times lower than California, according to the press release.
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.”
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.
Currently, there are no lab testing regulations for Florida’s medical cannabis market. Chris Martinez, co-founder and chief operating officer of EVIO Labs Florida, a veteran-owned business, is looking to change that.
When Martinez co-founded EVIO Labs Florida, he saw the need for a dedicated cannabis lab to ensure safety and quality of medicine for patients in the state. Partnering with EVIO Labs to accomplish this goal, Martinez secured a 5,500 sq. ft. facility in Broward County to test for potency, pesticides, microbial contaminants, terpenes, residual solvents and heavy metals. Their lab, a first of its kind in the industry, qualifies as a true pharmaceutical-grade clean room. This week, Martinez also secured their 2nd laboratory location in the City of Gainsville, where they will test for potency, microbials, terpenes and residual solvents. And he isn’t doing it on the cheap. “Our Broward lab is powered by Shimadzu with over $1.2M in the latest testing equipment utilizing LCMS technology with the world’s fastest polarity switching time of 5 m/sec and scan speeds of 30,000 u/sec with UF Qarray sensitivity 90 times that of previously available technologies,” says Martinez.
Martinez, an entrepreneur at heart, started the lab with a team of experts to become the first completely cannabis-focused laboratory in Florida. Jorge Segredo, their head chemist and quality assurance director, has over 18 years of experience in the development of nutraceutical and pharmaceutical products under ISO and FDA accreditation. Segredo has helped launch three independent FDA-accredited laboratories and has extensive knowledge of HPLC, GCMS, LCMS, ICPMS technologies and development/validation of testing methods and procedures. Cynthia Brewer, their director of operations, was an active participant in the 2017 state legislative session and has been an advocate for medical cannabis, working with legislators on a suitable framework to increase patient access to cannabis.
EVIO is one of the nation’s leaders in cannabis testing, research science and advisory services. It is an evolving network of laboratories with nine EVIO cannabis laboratories operating in five different states: Oregon, Colorado, Massachusetts, Florida and California. “After speaking with industry chemists around the country for months, the EVIO name was constantly brought up in conversation,” says Martinez. “When we spoke with the EVIO Team it was an easy decision for us to partner.” He says Lori Glauser, chief operating officer of EVIO, and William Waldrop, chief executive officer of EVIO, are truly visionaries in the cannabis industry.
According to Martinez, their licensing agreement with EVIO Labs (OTC:SGBYD) marked a first for the publicly traded company with exclusivity in the Florida market. The agreement includes proprietary testing methodologies, operating procedures, training and support.
In addition to testing cannabis for safety and quality, they are launching a technology platform called MJ Buddy, essentially a software tool that takes efficacy feedback from patients and uses testing and genetic data they gather from EVIO Labs across the country. “This will provide real data to the cannabis industry as to the medical benefits for thousands of patients in relation to the genotype and cannabinoid profiles of their medicine,” says Martinez.
Of the states that have legalized some form of cannabis, a large number of them have some lab testing regulations on the book, with some more comprehensive than others. Martinez says he hopes the Florida Department of Health, Office of Medical Marijuana Use follows some of the more thorough state programs, such as Oregon. His team has compiled a set of documents for regulators with recommendations for regulating the lab testing industry.
Without any regulations on paper, it is up to businesses to produce safe and quality medicine, without any oversight. EVIO Labs Florida follows FDA Good Laboratory Practices, has an ISO 17025:2005 accreditation pending, and is working on TNI 2016 accreditation.
When discussing what he wants to see happen with Florida’s regulatory framework, Martinez says the rules need to be specific to Florida. For example, due to the climate being so humid, microbial contaminant testing for things like yeast and mold will be particularly imperative. Because processing methods like butane and alcohol extraction are legal, he emphasizes the need for comprehensive residual solvents testing. “The most important regulation would be to have the laboratories select the samples at the MMTC facility and have the state randomly verify laboratory results to ensure accurate unbiased testing,” says Martinez.
In addition to that, he hopes their pesticide thresholds will be realistic and based on actual science. “We believe the public should receive carcinogenic data for products that are inhaled,” says Martinez. “Chemicals may be introduced into the processing of cannabis to vape liquid that may cause harm. This is important information for public health and communication of the risk related to exposure to such materials.” Martinez says EVIO Labs Florida was founded on the belief that through technology and science we can increase safety and patient outcomes.
Dana Ciccone, chief executive officer of Steep Hill Hawaii, has been a patient advocate and leader in cannabis education in Hawaii, as well as a member of the Hawaii Medical Marijuana Dispensary Task Force, an organization formed by the University of Hawaii College of Social Sciences Public Policy Center to develop regulations for the state. “We are proud not only to be the first cannabis lab to be licensed in the State of Hawaii, but also now the first lab to achieve ISO certification as well,” says Ciccone. “Industry businesses, medical professionals, state regulators, and patients can be confident that our lab and its testing standards will operate to the highest international standards.”
According to the press release, the laboratory will offer services for testing cannabinoid profiles (potency), terpenes, pesticides, heavy metals, biological screening, and residual solvents, testing for 17 Cannabinoids and 43 terpenes. The release states they are locally owned and operated, providing testing services for not just industry businesses, but in-state card-holding patients as well.
“This is a turning point for the industry – we have moved very quickly to raise the industry standards in Hawaii to internationally recognized certification,” says Ciccone. “I am very proud our scientific team for the professionalism and hard work they put in to achieve this certification.”
Demand for cannabis extracts, in particular vaping products, is at an all-time high. People want good oil, and they want to know something about the quality of it. It is therefore time to take a step back and consider the process from plant to cartridge. What is the current industry standard for cannabis extraction, what constitutes quality and where might we need to make some adjustments?
Right now, “clear” oil is hot. Customers have been led to believe that a pale gold extract is synonymous with the best possible cannabis concentrate, which is not necessarily the case. Producing a 95% pure THC extract with a translucent appearance is neither a great scientific feat nor a good representation of the whole cannabis flower. Moreover, it runs counter to the current trend of all-natural, non-processed foods and wellness products.
“My carrots are organic and fresh from the farmers market, my drink has no artificial sweeteners and my honey is raw, but my cannabis oil has undergone a dozen steps to look clear and still contains butane.”Cannabis is a fascinating plant. It is the basis of our livelihood, but more importantly, it enhances the quality of life for patients. The cannabis plant offers a plethora of medicinally interesting compounds. THC, CBD and terpenes are the most popular, but there are so many more. As of the most recent count, there are 146 known cannabinoids1. Cannabinoids are a group of structurally similar molecules2, including THC and CBD, many of which have shown biological activity3.
Then there are terpenes. These are the smaller molecules that give cannabis its distinct smell and flavor, over 200 of which have been identified in cannabis4. But wait, there’s more. The cannabis plant also produces countless other metabolites: flavonoids, alkaloids, phenols and amides5. All these components mixed together give the often-cited entourage effect6,7.
Current industry standards for cannabis oil extraction and purification stand in marked contrast to the complexity of the plant’s components. Due to an unsophisticated understanding of the extraction process and its underlying chemistry, cannabis oil manufacturers frequently produce oil of low quality with high levels of contamination. This necessitates further purifications and clean up steps that remove such contaminants unfortunately along with beneficial minor plant compounds. If one purifies an extract to a clear THC oil, one cannot also offer the full spectrum of cannabinoids, terpenes and other components. Additionally, claiming purities around 95% THC and being proud of it, makes any self-respecting organic chemist cringe8.
The labor-intensive, multi-step extraction process is also contrary to “the clean-label food trend”, which “has gone fully mainstream”9. Exposing the cannabis flower and oil to at least half a dozen processing steps violates consumer’s desire for clean medicine. Furthermore, the current practice of calling supercritical-CO2-extracted oils solvent-less violates basic scientific principles. Firstly, CO2 is used as a solvent, and secondly, if ethanol is used to winterize10, this would introduce another solvent to the cannabis oil.
We should reconsider our current extraction practices. We can offer cannabis extracts that are free of harmful solvents and pesticides, give a better, if not full, representation of the cannabis plant and meet the patients’ desire for clean medicine. Realizing extracts as the growth-driver they are11 will make us use better, fresher starting materials12. Understanding the underlying science and learning about the extraction processes will allow us to fine-tune the process to the point that we target extract customized cannabis concentrates13. Those, in turn, will not require additional multi-step purification processes, that destroys the basis of the entourage effect.
The cannabis industry needs to invest and educate. Better extracts are the result of knowledgeable, skilled people using precise instruments. Backroom extraction with a PVC pipe and a lighter should be horror stories of the past. And only when the patient knows how their medicine is made can they make educated choices. Through knowledge, patients will understand why quality has its price.
In short, over-processing to make clear oil violates both the plant’s complexity and consumers’ desires. Let us strive for pure extracts, not clear. Our patients deserve it.

Willamette Week, a Portland-based publication, is hosting the 2017 Cultivation Classic with Farma, Cascadia Labs, Phylos Bioscience and the Resource Innovation Institute on May 12th. The event is a benefit for the Ethical Cannabis Alliance, an organization that promotes sustainability, labor standards and education surrounding the integrity and ethics of growing cannabis. Cultivation Classic is a competition for pesticide-free cannabis grown in Oregon, according to a press release.
While the event’s focus is on the competition, it is just as much a celebration of the craft cannabis community in Oregon. This year’s competition incorporates scientific collaboration like genetic sequencing for the winners by Phylos Bioscience and carbon accounting for all competitors. Keynote speakers include Ethan Russo, medical director of PHYTECS and Dr. Adie Po, co-founder of Habu Health. Congressman Earl Blumenauer, a prominent cannabis legalization advocate in Oregon, will also be speaking at the awards ceremony. You can check out the full schedule and speaker lineup here.
Raymond Bowser, breeder at Home Grown Natural Wonders, is a judge for this year’s Cultivation Classic. He speaks at cannabis conferences around the country and his business created a number of different strains, so he has experience with a myriad of growers and strains. “This time around everyone has really stepped up their game,” says Bowser. “The entries are noticeably better than last year.” When looking at the different samples sent to him, he sees a few key factors as most important in judging the quality. “What I am looking for is simple; a nice smell and a decent look, generally speaking,” says Bowser. “Aesthetics can tell you a lot about how it was grown, temperature changes and the overall care taken in cultivating and curing the flower.” For him, flavor, smell and aesthetics are the big variables to consider.
Those are factors that his company holds to high standards in their work, so he judges the samples based on the same variables. “It is what we strive for in our gardens and so far the samples I have tried are fantastic in that regard,” says Bowser. In other competitions that Bowser has judged in the past, they sent him between 40 and 60 strains to judge in seven days. “That is not conducive to a fair evaluation,” says Bowser. “Here, we are getting fourteen or so different strains, so we can sample one strain a day which is how I personally like to do it.”
Bowser is supportive of Cultivation Classic because of their emphasis on the craft industry. “We talk about craft cannabis and breeding craft cultivars at conferences around the country,” says Bowser. “With the rec industry growing so much, we see so many people cutting corners to save money, that it is refreshing to see growers take pride in the craft.” He also stresses the need for good lab testing and sound science in the trade. “I am big on lab testing; it is very important to get all the right analytics when creating strains,” says Bowser. “Cascadia is a solid choice for the competition; they have been a very good, consistent lab.” Emphasizing the local, sustainability-oriented culture surrounding the craft market, Bowser is pleased that this competition supports that same message. “We need to stay true to our Oregon roots and continue to be a clean, green, granola-eating state.”
Cascadia Labs is conducting the pesticide and cannabinoid analytics for all submissions and Phylos Bioscience will perform testing for the winners. According to Julie Austin, operations manager at Cascadia Labs, pesticide testing for the Oregon list of analytes was of course a requirement. “Some of the samples submitted had previous tests from us or from other accredited labs, but if they didn’t have those results we did offer a comprehensive pesticide test,” says Austin. The competition’s fee for submission includes the potency and terpenes analysis.
Jeremy Sackett, director of operations at Cascadia Labs, says they test for 11 cannabinoids and 21 terpenes. The samples are divided into groups of THC-dominant samples, CBD-dominant samples and samples with a 1:1 ratio of the two. “The actual potency data will be withheld from judges and competitors until the day of the event,” says Sackett. “We are data driven scientists, but this time we want to have a little fun and bring the heart of this competition back to the good old days: when quality cannabis was gauged by an experience of the senses, not the highest potency number.” The event will take place on May 12th at Revolution Hall in Portland, Oregon.

As the high-end cannabis market continues to grow, dispensary owners and product manufactures alike seek to fill the growing niche for high-end, luxury cannabis products.
When it comes to concentrates, many people are looking to rosin to fill this luxury niche. But not all rosin is the same, and poorly processed rosin can range from a dark almost burnt tasting sap, to something that’s almost bright orange in color. A poor rosin experience can leave a bad taste in a consumer’s mouth, and discourage them from trying more in the future.
For dispensary operators looking to expand their luxury concentrates, skip the hair-straightener rosin and look for SFO. When it comes to concentrates, nothing is more luxurious than solventless flower oil (or SFO). Like most luxury items, SFO comes at a higher price point than the average gram of oil. But for those in the know, the price is well worth it.
What is so great about SFO?
Clean: Most concentrates are made using dangerous chemical solvents like butane or propane. This can leave behind toxic heavy metals. SFO is solventless. It is made using a modified Rosin process, which uses only low heat and pressure in the extraction process.
Made From Flowers: Safety is one huge bonus of the method, and I always suggest that patients and recreational users alike avoid concentrates made with solvents. But SFO is also special in that it is made directly from the flowers of the cannabis rather than the trim, hash, or kief, and the process preserves the flowers’ natural terpenes.
Feels Better: Terpenes are the compounds in cannabis that give it its smell and taste. Each strain has a unique smell and taste because of it’s terpenes. They also affect the feel of the strain. If you love the way sour diesel tastes and feels, but hate lemon haze, it’s probably because of the terpenes in each.
Terpenes can also modify the effects of THC, lessening some of its negative side effects like accelerated heart-rate, paranoia, dry mouth and mental confusion.
In most extraction processes, most of the flower’s natural terpenes are destroyed. If you have ever excitedly bought a concentrate of your favorite strain only to find that it doesn’t taste or feel like the flower, it is likely because the terpenes weren’t retained.
Smells and Tastes Amazing: SFO has unprecedented natural terpene retention. This means it tastes incredible and feels like the flower it was made from.
Pressed at Low Temperatures: It’s important to note that not all Rosin is SFO. SFO is made using lower temperatures than the hair straightener and t-shirt press rosin that has flooded the market. High temperatures burn off the terpenes that make SFO so delicious. So, if you are making a purchase for your dispensary and you want a concentrate that will really knock your customer’s socks off, make sure the rosin is pressed at low temperatures and made from flower, not hash or kief.
Best Terpene Retention: When checking terpene analytics, beware of concentrates that have terpenes added back in. While we can isolate the terpenes we know about, we have only researched a subset of the terpenes in the cannabis plant. If we want to recreate the effect of a particular strain, we need to know all the compounds in it or the recipe won’t be right. Rosin with terpenes added back in tends to taste artificial and take on a brighter orange hue.
The most effective way of getting complex flavors and effects like those in the flower, is to preserve the compounds as they are in nature. That is exactly what SFO does.
If you are looking for that luxurious concentrate, SFO is bound to be a crowd pleaser with its potent, pleasant effects and clean, fragrant taste. Like many luxury items it is also rare, so finding a good supplier can be tricky.
For a great tasting SFO in CA, try out Fleurish Farm’s line of SFO. These Sonoma County rosin makers have perfected the art of terpene retention. Each flavorful option has a unique and complex aroma. And their terpene percentages are some of the highest around ranging from 3-9%.
