Encore Labs is a full-service cannabis testing lab in Pasadena, California, providing all testing needs required by California’s Bureau of Cannabis Control (BCC). The BCC requires that cannabis products being sold in licensed dispensaries be tested for cannabinoid potency, heavy metals, microbial impurities, moisture content and water activity, mycotoxins, residual pesticides, residual solvents and processing chemicals, foreign materials and terpenes. It is Encore Labs’ goal to guarantee the quality and potency of all cannabis products while ensuring regulatory guidelines are met in the state of California.
Encore Labs provides quick turnaround times on a consistent basis. They take pride in offering excellent customer service without diminishing the quality of the work that they do. Their team of laboratory analysts/technicians are passionate about the industry and will never compromise their integrity just to make an extra buck.
Co-Founder, Spencer Wong, mentions their personal connection with clients. “Our customers don’t just see us as their testing laboratory, they see Encore Labs as their laboratory partner,” says Wong. “Besides performing analytical testing, we have worked with many customers to help formulate new products and do root cause analysis to pinpoint inefficiencies in their manufacturing operations and cultivation farms.”
ISO/IEC 17025 Accreditation has been extremely valuable to Encore Labs, especially regarding the new cannabis testing industry. “Our experience with Perry Johnson Laboratory Accreditation, Inc. has been great and has allowed for a very smooth and straightforward initial accreditation process. Their staff has been knowledgeable and responsive every step of the way,” says Wong.
Accreditation establishes that steps are being taken regarding quality and that laboratories are meeting and exceeding the highest testing standards. It also provides further assurance and confidence in data results as well as validated methods, staff training procedures, equipment calibration and successful participation in proficiency testing/interlaboratory comparisons.
Starting out with 1500 square feet of laboratory space, within the last year Encore Labs has doubled its work area. In order to meet the growing demand of the cannabis testing industry, they have added plans to once again double in size by the end of 2019, as well as open a second laboratory by the end of 2020.
The cannabis industry is growing exponentially, and the use of cannabis for medical purposes is being adopted across the nation. With this boom in cannabis consumers, there has been an increasing need for knowledge about the product.
The role of testing labs has become crucial to the process, which makes owning and operating a lab more lucrative. Scientists testing for potency, heavy metals, pesticides, residual solvents, moisture, terpene profile, microbial and fungal growth, and mycotoxins/aflatoxins are able to make meaningful contributions to the medical industry by making sure products are safe, while simultaneously generating profits and a return on investment.
Here are the key testing instruments you need to conduct these critical analyses. Note that cannabis analytical testing requirements may vary by state, so be sure to check the regulations applicable to the location of your laboratory.
The most important component of cannabis testing is the analysis of cannabinoid profiles, also known as potency. Cannabis plants naturally produce cannabinoids that determine the overall effect and strength of the cultivar, which is also referred to as the strain. There are many different cannabinoids that all have distinct medicinal effects. However, most states only require testing and reporting for the dry weight percentages of delta-9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD). It should be noted that delta-9-tetrahydrocannabinolic acid (Δ9-THCA) can be converted to THC through oxidation with heat or light.
For potency testing, traditional high-performance liquid chromatography (HPLC) is recommended and has become the gold standard for analyzing cannabinoid profiles. Look for a turnkey HPLC analyzer that delivers a comprehensive package that integrates instrument hardware, software, consumables and proven HPLC methods.
Heavy Metal Testing
Different types of metals can be found in soils and fertilizers, and as cannabis plants grow, they tend to draw in these metals from the soil. Heavy metals are a group of metals considered to be toxic, and the most common include lead, cadmium, arsenic and mercury. Most labs are required to test and confirm that samples are under the allowable toxic concentration limits for these four hazardous metals.
Heavy metal testing is performed by inductively coupled plasma mass spectrometry (ICP-MS). ICP-MS uses the different masses of each element to determine which elements are present within a sample and at what concentrations. Make sure to include accompanying software that provides assistant functions to simplify analysis by developing analytical methods and automatically diagnosing spectral interference. This will provide easy operation and analytical results with exceptionally high reliability.
To reduce running costs, look for a supporting hardware system that reduces the consumption of argon gas and electricity. For example, use a plasma ignition sequence that is optimized for lower-purity argon gas (i.e., 99.9% argon as opposed to more expensive 99.9999%).
The detection of pesticides in cannabis can be a challenge. There are many pesticides that are used in commercial cannabis grow operations to kill the pests that thrive on the plants and in greenhouses. These chemicals are toxic to humans, so confirming their absence from cannabis products is crucial. The number of pesticides that must be tested for varies from state to state, with Colorado requiring only 13 pesticides, whereas Oregon and California require 59 and 66 respectively. Canada has taken it a step further and must test for 96 pesticides, while AOAC International is developing methods for testing for 104 pesticides. The list of pesticides will continue to evolve as the industry evolves.
Testing for pesticides is one of the more problematic analyses, possibly resulting in the need for two different instruments depending on the state’s requirements. For a majority of pesticides, liquid chromatography mass spectrometry (LCMS) is acceptable and operates much like HPLC but utilizes a different detector and sample preparation.
Pesticides that do not ionize well in an LCMS source require the use of a gas chromatography mass spectrometry (GCMS) instrument. The principles of HPLC still apply – you inject a sample, separate it on a column and detect with a detector. However, in this case, a gas (typically helium) is used to carry the sample.
Look for a LC-MS/MS system or HPLC system with a triple quadrupole mass spectrometer that provides ultra-low detection limits, high sensitivity and efficient throughput. Advanced systems can analyze more than 200 pesticides in 12 minutes.
For GCMS analysis, consider an instrument that utilizes a triple quadrupole mass spectrometer to help maximize the capabilities of your laboratory. Select an instrument that is designed with enhanced functionality, analysis software, databases and a sample introduction system. Also include a headspace autosampler, which can also be used for terpene profiles and residual solvent testing.
Residual Solvent Testing
Residual solvents are chemicals left over from the process of extracting cannabinoids and terpenes from the cannabis plant. Common solvents for such extractions include ethanol, butane, propane and hexane. These solvents are evaporated to prepare high-concentration oils and waxes. However, it is sometimes necessary to use large quantities of solvent in order to increase extraction efficiency and to achieve higher levels of purity. Since these solvents are not safe for human consumption, most states require labs to verify that all traces of the substances have been removed.
Testing for residual solvents requires gas chromatography (GC). For this process, a small amount of extract is put into a vial and heated to mimic the natural evaporation process. The amount of solvent that is evaporated from the sample and into the air is referred to as the “headspace.” The headspace is then extracted with a syringe and placed in the injection port of the GC. This technique is called full-evaporated technique (FET) and utilizes the headspace autosampler for the GC.
Look for a GCMS instrument with a headspace autosampler, which can also be used for pesticide and terpene analysis.
Terpene Profile Testing
Terpenes are produced in the trichomes of the cannabis leaves, where THC is created, and are common constituents of the plant’s distinctive flavor and aroma. Terpenes also act as essential medicinal hydrocarbon building blocks, influencing the overall homeopathic and therapeutic effect of the product. The characterization of terpenes and their synergistic effect with cannabinoids are key for identifying the correct cannabis treatment plan for patients with pain, anxiety, epilepsy, depression, cancer and other illnesses. This test is not required by most states, but it is recommended.
The instrumentation that is used for analyzing terpene profiles is a GCMS with headspace autosampler with an appropriate spectral library. Since residual solvent testing is an analysis required by most states, all of the instrumentation required for terpene profiling will already be in your lab.
As with residual solvent testing, look for a GCMS instrument with a headspace autosampler (see above).
Microbe, Fungus and Mycotoxin Testing
Most states mandate that cannabis testing labs analyze samples for any fungal or microbial growth resulting from production or handling, as well as for mycotoxins, which are toxins produced by fungi. With the potential to become lethal, continuous exposure to mycotoxins can lead to a buildup of progressively worse allergic reactions.
LCMS should be used to qualify and identify strains of mycotoxins. However, determining the amount of microorganisms present is another challenge. That testing can be done using enzyme linked immunosorbent assay (ELISA), quantitative polymerase chain reaction (qPCR) or matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), with each having their advantages and disadvantages.
For mycotoxin analysis, select a high-sensitivity LC-MS/MS instrument. In addition to standard LC, using an MS/MS selective detector enables labs to obtain limits of detection up to 1000 times greater than conventional LC-UV instruments.
For qPCR and its associated needs, look for a real-time PCR amplification system that combines thermal cyclers with optical reaction modules for singleplex and multiplex detection of fluorophores. These real-time PCR detection systems range from economical two-target detection to sophisticated five-target or more detection systems. The real-time detection platform should offer reliable gradient-enabled thermal cyclers for rapid assay optimization. Accompanying software built to work with the system simplifies plate setup, data collection, data analysis and data visualization of real-time PCR results.
Moisture Content and Water Activity Testing
Moisture content testing is required in some states. Moisture can be extremely detrimental to the quality of stored cannabis products. Dried cannabis typically has a moisture content of 5% to 12%. A moisture content above 12% in dried cannabis is prone to fungal growth (mold). As medical users may be immune deficient and vulnerable to the effects of mold, constant monitoring of moisture is needed. Below a 5% moisture content, the cannabis will turn to a dust-like texture.
The best way to analyze the moisture content of any product is using the thermogravimetric method with a moisture balance instrument. This process involves placing the sample of cannabis into the sample chamber and taking an initial reading. Then the moisture balance instrument heats up until all the moisture has been evaporated out of the sample. A final reading is then taken to determine the percent weight of moisture that was contained in the original sample.
Look for a moisture balance that offers intuitive operation and quick, accurate determination of moisture content. The pan should be spacious enough to allow large samples to be spread thinly. The halogen heater and reflector plate should combine to enable precise, uniform heating. Advanced features can include preset, modifiable measurement modes like automated ending, timed ending, rapid drying, slow drying and step drying.
Another method for preventing mold is monitoring water activity (aW). Very simply, moisture content is the total amount of water available, while water activity is the “free water” that could produce mold. Water activityranges from 0 to 1. Pure water would have an aW of 1.0. ASTM methods D8196-18 and D8297-18 are methods for monitoring water activity in dry cannabis flower. The aW range recommended for storage is 0.55 to 0.65. Some states recommend moisture content to be monitored, other states monitor water activity, and some states such as California recommend monitoring both.
As you can see, cannabis growers benefit tremendously from cannabis testing. Whether meeting state requirements or certifying a product, laboratory testing reduces growers’ risk and ensures delivery of a quality product. As medicinal and recreational cannabis markets continue to grow, analytical testing will ensure that consumers are receiving accurately
labeled products that are free from contamination. That’s why it is important to invest in the future of your cannabis testing lab by selecting the right analytical equipment at the start of your venture.
Good news came to patients using medical cannabis in Arizona earlier this week: Lawmakers in Arizona unanimously passed SB1494 through the state’s House and Senate, the bill requiring mandatory lab testing for medical cannabis products. Arizona Governor Doug Ducey is expected to sign the bill and has ten days to do so.
When Governor Ducey signs the bill into law it will mark the first time since the state legalized medical cannabis in 2011 that a measure to protect patient safety via lab testing will be implemented. According to the bill, beginning November 1, 2020, all cannabis products shall be tested prior to sales “to determine unsafe levels of microbial contamination, heavy metals, pesticides, herbicides, fungicides, growth regulators and residual solvents and confirm the potency of the marijuana to be dispensed,” (Page 6, Section 36-2803).
The bill requires dispensaries to provide test results to patients immediately upon request. Dispensaries need to display a sign notifying patients of their right to see “certified independent third-party laboratory test results for marijuana and marijuana products for medical use,” according to the text of the bill (Page 7, Section 36-2803.01).“There will have to be some serious planning, but other states have achieved this and we can too.”
Under the new bill, the Arizona Department of Health Services will adopt rules to certify and regulate labs, establishing requirements like health and safety protocols, mandatory quality assurance program and standards, chain of custody and sampling policies, adequate records, accreditation, proficiency testing, among other requirements (Page 6-7, Section 36-2803).
Ryan Treacy, co-founder of the Arizona Cannabis Laboratory Association (ACLA) and CEO/Founder of C4 Laboratories, says this is a major turning point for Arizona’s cannabis industry. “We have been devoid of regulations with regard to testing the entirety of the program since it was legalized; This will be a significant change,” says Treacy. “Now patients can make sure they are getting a safe and clean product and getting exactly what they paid for.”
For those in the know when it comes to cannabis testing in the United States, the new requirements will look very similar to other states with testing requirements. One particularly unique aspect of the new program, however, is the establishment of a “Medical Marijuana Testing Advisory Council,” made up of stakeholders representing different interests in Arizona’s cannabis industry. Members of the council will include representatives from dispensaries, labs, cultivators, concentrate producers, edibles producers, as well as registered patients, caregivers, a representative from the Arizona Department of Public Safety, a licensed health care provider and “any other members deemed necessary by the director,” reads the text of the bill (page 16, Section 36-2821).
“Other states like California have complained about detection limits, while Arizona is taking a unique approach with an advisory council with stakeholders in the cannabis industry,” says Treacy. “So that when the Department of Health Services promulgates rules, they are taking into account the challenges in the cannabis industry specifically. We have a chance to do this right and avoid pitfalls we’ve seen in other states.”
One problem worth mentioning for Arizona’s cannabis industry: Dispensaries have not been required to test products for patients since medical cannabis was legalized back in 2011. That means many producers could be very used to operating procedures that don’t account for lab testing. With mandatory lab testing, some producers may be behind the curve when it comes to mitigating contamination.
According to Treacy, this could disrupt the supply chain a little bit. “When testing becomes mandatory in November 2020, dispensaries will need a full panel of tests performed on their samples,” says Treacy. “With the entire market now required to complete a full panel in depth analysis on each product, product testing will become a more time-consuming stop in the supply chain. So companies will need to work that into their plan to meet regulation requirements to prevent a bottleneck and maintain patients’ access to their cannabis medicine.”
Arizona has a chance to prevent that type of bottleneck seen in states that implemented testing requirements, like California for example. “When you have a habitual history of not testing products, it can be very hard to change, which adds to Arizona’s challenges,” says Treacy. “We need to make sure this does not affect access for patients and the ability of the industry to continue to flourish and grow.”
While Treacy thinks the transition will be difficult for some, it’s absolutely necessary for Arizona’s patients to access clean and safe medicine. “There will have to be some serious planning, but other states have achieved this and we can too.”
According to a press release published on April 3, Keystone State Testing (doing business as Dakota State Testing) became the first laboratory authorized to test cannabis in North Dakota. The lab also obtained their ISO 17025 accreditation for cannabis testing from the American Association of Laboratory Accreditation (A2LA), which is another first achievement for cannabis testing in the state of North Dakota.
Dr. Kelly Greenland, chief science officer at Keystone State Testing, says the North Dakota Department of Health set a high standard for the cannabis lab testing industry in the state. “Keystone State Testing is once again proud to of this monumental achievement and critical milestone in the company’s history to have met the highest levels of standards set forth by both A2LA and the North Dakota Department of Health,” says Greenland. “Keystone chose A2LA as its Accreditation Body due to their reputation in the industry, their diverse clientele, and the quality of their assessors. A2LA’s assessors have spent decades in their respective fields, which helps to ensure that Keystone is providing the best services possible to their clients, regulators and patients.”
Keystone State Testing’s ISO 17025 accreditation scope covers 11 testing methods at their facility in Fargo, North Dakota. Those methods include: Cannabinoid potency analysis, cannabinoid profile, moisture content, residual solvents, water activity, along with microbiological tests like total yeast and mold count, E. coli, Salmonella, total aerobic microbial count, among others.
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.
Manufacturers of cannabis products need a program tailored to the cannabis industry that helps assure the safety of cannabis products with respect to known hazards such as pesticides, residual solvents, microbial impurities, heavy metals and mycotoxins. Deibel Cannabis Laboratories has developed a course that that will teach those manufacturing cannabis products how to manage known product safety hazards using a Hazard Analysis and Critical Control Point (HACCP) system.
HACCP has a long history of use in the food industry based on preventing potential hazards from occurring rather than reacting to issues when they arise. This program was started in the US but is globally recognized, used by food companies around the world to help produce safe products for consumers. Deibel Cannabis Laboratories applies the same prevention based system of HACCP to the creation of safe and wholesome cannabis goods whether they be edible, medicinal or topical. They also explore ways cultivators can use HACCP principles in their operation.12
Deibel Labs was founded by Dr. Robert Deibel in the 1970’s. Dr. Deibel is one of the original pioneers of HACCP, expanding the program from its original three HACCP principles to the seven principles we recognize today. Dr. Deibel developed the first “HACCP Short Course,” teaching this prevention-based program to food industry leaders in the 1970s.
According to Charles Deibel, president of Deibel Labs, this is an important step for the cannabis space. “Deibel Labs is proud to continue in our historic role as leaders in HACCP training by providing the cannabis industry with a training course developed by Deibel Labs associates who are International HACCP Alliance accredited lead instructors with years of experience in crafting and implementing HACCP plans for the food industry.”
They are launching a pilot two-day Cannabis HACCP Class to select clients at the end of January in Santa Cruz, CA. The full Cannabis HACCP course schedule for 2019 is currently in development. Accreditation by the HACCP Alliance is expected by early January, assuring that a standardized and internationally recognized training curriculum is provided by accredited instructors.
The course is forward-thinking, anticipating that sometime in the near future cannabis manufacturers will be required to control and document the safe production, handling and preparation of products according to state or even federal regulatory standards. Participants will be able to develop their own model HACCP program in an interactive group learning environment.
Understand how Prerequisite Programs provide the foundation on which HACCP programs are built including GMPs, Sanitation and Pest Control Programs

Fast-forward almost a year and EVIO Labs Florida is continuing their expansion in the state, now with locations in Broward County and Gainesville. “We are always looking at opportunities to better serve our clients and the patients of Florida,” says Martinez. “Opening Gainesville within a year of Davie was a goal we set for our team. We knew there was a need and opening Gainesville helped support the continued growth of FL medical marijuana program.” He says that between the two locations, they can now process upwards of 1,400 samples a day.
According to Martinez, much of that expanded throughput is thanks to their partnership with Shimadzu. “Our relationship with Shimadzu is very unique,” says Martinez. “Shimadzu instrumentation allows us to test in parts per billion for accuracy and sensitivity levels that empower us to see deep into the chemical makeup of these medicines. Operating in this space where speed and turnaround times are key, these instruments provide us with a platform to meet 24/48-hour deadlines.” They can now screen for contaminants such as pesticides, heavy metals, residual solvents, mycotoxins, aflatoxins and pathogens using instruments such as HPLC, GC-MS/MS, LC-MS/MS and ICP-MS, all provided by Shimadzu.
While Florida doesn’t currently have a final rule on testing thresholds, there are proposed regulations that would require independent lab testing for medical cannabis products. “Our clients are self-regulating at this time and in favor of the current proposed regulation,” says Martinez. “The proposed regulations will give Florida the most comprehensive and stringent testing regulation in the U.S. and arguably the world.”
For Martinez and the rest of the EVIO Labs Florida team, this is about protecting public health. “Our lab’s main focus is always first and foremost patient safety,” says Martinez. “As the market continues to grow, we continue to innovate through business intelligence software and other technologies to streamline the testing process for our customer’s.”
Last month, G3 Labs LLC, a Las Vegas-based cannabis-testing lab, had their license suspended for an unknown regulatory compliance issue. According to Stephanie Klapstein, spokeswoman for the Nevada Department of Taxation, the reason why their license was suspended is confidential. “We can’t disclose the details of the suspension, including anything about penalties,” says Klapstein.
When asked about the license suspension, Klapstein told us it was a compliance issue, but could not go into detail. “I can confirm that we did suspend G3’s license for compliance issues,” says Klapstein. “We are working with them to bring them back into compliance. In the meantime, they cannot operate.” Klapstein told the Las Vegas Review-Journal that the Nevada Department of Agriculture tested cannabis samples from the lab to determine if there was a need for a recall. She also confirmed with us that the compliance issue does not necessitate any product recalls.
According to the Las Vegas Review-Journal, this is the first time a cannabis business license is suspended in the state since the beginning of adult-use sales back in July of this year. Nevada’s cannabis regulations require independent lab testing of products before they reach shelves. That required testing includes checking for potency, microbials, pesticides, residual solvents, moisture content, growth regulators, Mycotoxins and foreign matter.
When we reached out to G3 Labs, they did not immediately respond to a request for comment.
Dr. Chao-Hsiung Tung, lab director at G3 Labs, told the Las Vegas Review-Journal that they couldn’t comment, based on advice from their legal counsel. “G3 Labs is actively sorting out the issues with the Department,” Dr. Tung told the Review-Journal in an email.
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.
Emerald Scientific recently announced their proficiency-testing program, The Emerald Test, has been approved by Colorado as a third party provider for proficiency testing in licensed cannabis laboratories. The Emerald Test, held twice annually, is an inter-laboratory comparison and proficiency test (ILC-PT), allowing data to be collected pertaining to the performance of laboratories on a national scale. Proficiency testing is designed to measure how accurately laboratories perform and is a critical tool for quality assurance.
Colorado requires labs to participate in a proficiency-testing program in order to be certified to conduct required testing on cannabis and cannabis products for safety and quality. According to the press release, Colorado’s Marijuana Enforcement Division, under the Department of Revenue, conducted an evaluation process to determine which applicants could meet the performance standards for regulatory compliance concerning proficiency testing. The contract was awarded to Emerald Scientific following this evaluation process.
According to Ken Groggel, director of the Proficiency Testing Program at Emerald Scientific, a number of states have recognized the need for independent proficiency testing as a required piece of regulatory compliance. “The Emerald Test Inter-Laboratory Comparison/PT is state approved in Washington & Colorado for cannabis testing laboratory licensure,” says Groggel. “States with cannabis or hemp production, as well as labs in other countries are now actively participating in the Emerald Test as a tool for quality improvement, efficiency upgrades and product safety.” He says the Colorado Marijuana Enforcement Division has contracted with Emerald Scientific to provide third party PT programs for microbial contaminants, residual solvents and pesticides.
Beginning in 2014, The Emerald Test has been offered twice a year and, in 2017, over 50 labs participated from 14 states and 2 countries. “Laboratories that have enrolled more than once have seen significant improvement in their results, an indicator of improved performance for industry customers,” says Groggel.
Proficiency testing is important for ensuring quality, safety and product content accuracy. “This should be the priority whether you are a grower, manufacturer, testing laboratory, regulatory entity, medical patient or adult use consumer,” says Groggel. It also helps labs meet regulatory requirements and achieve ISO 17025 accreditation. “Independent proficiency testing helps determine if the lab is able to deliver the services marketed to its customers,” says Groggel. “Regulatory agencies can use this information when licensing, monitoring & enforcing good science for public safety.”
As new states legalize cannabis and develop consumer protection regulations, proficiency testing programs can help labs demonstrate their commitment to responsible and accurate testing. “When PT results show the cannabis testing lab is capable it is up to the government to ensure accountability for performance on behalf of all its citizens,” says Groggel. Labs can enroll starting on September 25th in the Fall 2017 Emerald Test ILC/PT.
