Aurum Labs, a cannabis testing laboratory based in Durango, Colorado, announced last week that they have become certified by the Colorado Department of Public Health and Environment (CDPHE) for all of the compliance testing required for hemp products. The press release says they are the first independent lab that is actually based in the state to receive the CDPHE certification for every compliance test.
Last year, Colorado rolled out hemp testing regulations that are some of the most comprehensive in the world. The required pesticide screening includes testing for more than 100 different types of pesticides. The new rules, along with the certification requirement, make it difficult for labs to enter the market, with only eleven total labs certified by the CDPHE for various hemp compliance panels and only five certified for every type of test, according to the department’s website.
Most of the companies on that list certified to conduct hemp compliance testing are familiar labs with large footprints, such as Eurofins, Kaycha Labs, Columbia Labs, SC Labs, InfiniteCAL and ACS Labs. Most of these labs are out of state and by the looks of it, only four independent, Colorado-based labs are certified so far: Aurum Labs, Gobi Analytical, Botanacor Labs and Minova Labs. Gobi and Minova, however, are not yet certified for pesticide testing, while Aurum appears to be certified for all compliance testing. Botanacor Labs, based in Denver, was certified back in June of 2021 to every compliance test except for pesticides.
“It’s difficult to compete with these large, private-equity-funded labs, but Aurum is passionate about serving the evolving hemp industry” Liz Mason, director of operations at Aurum Labs, said in a press release. “We are committed to staying on the scientific forefront to give the most comprehensive services to our clients.”
Earlier this year, the Colorado Department of Public Health and Environment (CDPHE) announced a plan to introduce new testing rules for the state’s growing hemp industry. Under the new regulations, hemp products must be tested for residual solvents, heavy metals and pesticides, in addition to making sure they contain less than 0.3% THC.
The CDPHE are planning on a gradual rollout to prevent any supply chain issues or a lab testing bottleneck, similar to what we’ve seen in other states launching new testing requirements in years past, such as Arizona or California. Well, the Colorado rollout appears to be hitting similar snags and because of supply chain issues related to instruments and consumables in laboratories, the implementation of those testing rules is somewhat delayed. What was originally supposed to be implemented over the summer was pushed back to an October 1 deadline, and that deadline has now been pushed back to 2022.
The pesticide testing list to be implemented January 1, 2022
As a result of supply chain shortages and the learning curve to test for such a wide range of pesticides, Colorado is opening hemp testing to out-of-state labs in an effort to stay on schedule with the rollout. Dillon Burns, lab manager at InfiniteCAL, a cannabis testing company with locations in California and Michigan, just completed an audit with the CDPHE in their work to get certified and start conducting hemp testing for businesses in Colorado.
Burns says they’re well-acquainted with the list of pesticides because of how similar the list is to California’s requirements. “For the pesticide testing rules that were supposed to go into effect on August 1st, it’s basically the same list as California just with slightly different action levels,” says Burns. “I would say these action limits are generally stricter – they have much lower LOQs [limits of quantification].”
The pesticide testing list (continued) to be implemented January 1, 2022
Come January 1, 2022, they are expecting an additional 40 pesticides to be required under the new rules. “But currently, it’s still unclear when these regulations will actually go into effect,” says Burns. The full pesticide testing list is currently slated to be implemented on April 1, 2022.
The supply chain issues referenced above have a lot to do with what the state is asking labs to test for. Previously, most of the pesticides tested for under Colorado’s adult use and medical cannabis programs could be analyzed with an LC/MS. A handful of pesticides on the new list do require GC/MS, says Burns. It’s entirely possible that a lot of labs in Colorado just don’t have a GC/MS or are in the process of training staff and developing methods for using the new instrument. “Cleanliness of these instruments is such a priority that it takes time to acquire the right skill set for it,” says Burns.

The new testing rollout isn’t just another compliance hurdle for the cannabis industry; these rules are about protecting public health. Dillon Burns said he’s seen hiccups in California with the amount of new hemp farmers getting into the space. “The hemp products we’ve tested in California often fail for pesticides,” says Burns. It’s a lot easier in most states to get a license for growing hemp than it would be for growing adult use cannabis. “You’ll see a lot more novice growers getting into hemp farming without a background in it. They’ll fail for things they just haven’t considered, like environmental drift. We see a lot of fails in CA. Hemp is bioaccumulating so it presents a lot of problems. If they’re not required to look for it, they weren’t monitoring it.”
When asked how the market might react to the new rules, Burns was confident that Colorado knows what they’re doing. “I don’t anticipate that [a testing bottleneck] happening here. The regulators are reasonable, supportive of the industry and opening it up to out-of-state labs should help in preventing that.”
Cannabis, we have a problem. Legalizing adult use cannabis in California caused the demand for high-potency cannabis to increase dramatically over the last several years. Today, many dispensary buyers enforce THC minimums for the products that they sell. If smokeable flower products don’t have COAs proving the THC levels are above 20% or more, there is a good chance many dispensaries won’t carry them on their shelves. Unfortunately, these kinds of demands only put undue pressure on the industry and mislead the consumer.
Lab Shopping: Where the Problems Lie
Lab shopping for potency analysis isn’t new, but it has become more prevalent with the increasing demand for high-potency flower over the last couple of years. Sadly, many producers submit valid, certified COAs to the California Bureau of Cannabis Control (BCC), which show two to three times the actual potency value.
At InfiniteCAL, we’ve purchased products from dispensary shelves and found significant discrepancies between the analysis we perform and the report submitted to the BCC by the producer. So, how can this happen? Several factors are creating the perfect storm in cannabis testing.
Problems with Potency
Many consumers still don’t understand that THC potency is not the only factor in determining quality cannabis, and they are unwittingly contributing to the demand for testing and analysis fraud. It is alarming for cultivation pioneers and ethical labs to see producers and profit-hungry testing facilities falsifying data to make it more appealing to the unaware consumer.
Basically, what’s happening is growers are contacting labs and asking, “I get 30% THC at this lab; what can you do?” When they see our COA reporting their flower tested lower than anticipated, they will go to another lab to get higher test results. Unfortunately, there are all too many labs that are willing to comply.
I recently saw a compliant COA that claimed that this particular flower was testing at 54% THC. Understanding cannabis genetics, we know this isn’t possible. Another product I reviewed claimed that after diluting an 88% THC distillate with 10-15% terpenes, the final potency test was 92% THC. You cannot cut a product and expect the potency to increase. Finally, a third product we reviewed claimed 98% total cannabinoids (while only looking at seven cannabinoids) with 10% terpenes for a total of 108% of the product.
These labs only make themselves look foolish to professionals, mislead laymen consumers and skirt under the radar of the BCC with basic mathematical errors.
The Pesticide Predicament
Frighteningly, inflating potency numbers isn’t the most nefarious testing fraud happening in the cannabis industry. If a manufacturer has 1000 liters of cannabis oil fail pesticide testing, they could lose millions of dollars – or have it retested by a less scrupulous lab.

As the industry continues to expand and new labs pop up left and right, cultivators and manufacturers have learned which labs are “easy graders” and which ones aren’t. Certain labs can miss up to ten times the action level of a pesticide and still report it as non-detectable. So, if the producer fails for a pesticide at one lab, they know four others won’t see it.
In fact, I’ve had labs send my clients promotional materials guaranteeing compliant lab results without ever receiving a sample for testing. So now, these companies aren’t just tricking the consumer; they are potentially harming them.
An Easy Fix
Cannabis testing is missing just one critical factor that could quickly fix these problems – checks and balances. The BCC only needs to do one of two things:
Verifying Lab Accuracy
InfiniteCAL also operates in Michigan, where the Marijuana Regulatory Agency (MRA) has already implemented a system to ensure labs are maintaining the highest testing standards. The MRA will automatically flag all COAs which test above a certain percentage and require the product to be retested by multiple labs.
Labs are required to keep a back stock of material. So, when test results come back abnormally high from Lab A, then Labs B, C and D are commissioned to retest the material to compare data. If Lab A reports 40% THC, but the other labs all report 18%, then it’s easy to see Lab A has made an error.
Secret Shopping
By simply buying products off the shelves and having them blind-tested by other labs, it would be simple for the BCC to determine if the existing COA is correct. They already have all the data in Metrc, so this would be a quick and easy fix that could potentially solve the problem overnight.
For example, at InfiniteCAL, we once purchased 30 samples of Blue Dream flower from different cultivators ranging in certified COA potencies from 16% to 38%. Genetically, we know the Blue Dream cultivar doesn’t produce high levels of THC. When we tested the samples we purchased, nearly every sample came back in the mid-teens to low 20% range.
Labs Aren’t Supposed to Be Profit Centers
At InfiniteCAL, we’ve contacted labs in California where we’ve uncovered discrepancies to help find and flush out the errors in testing. All too often, we hear the excuses:
“If I fix my problem, I’ll lose my clients.”
“I’m just a businessman who owns a lab; I don’t know chemistry.”
“My chemist messed up; it’s their fault!”
If you own a lab, you are responsible for quality control. We are not here to get rich; we are here to act as public safety agents who ensure these products are safe for the consumer and provide detailed information about what they choose to put in their bodies. Be professional, and remember you’re testing for the consumer, not the producer.
