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%.
