How Colorado Didn’t Regulate and Maintain Intoxicating Hemp Off the Cabinets — ProPublica

The proprietor of a marijuana testing lab referred to as a prime regulator in Colorado on his cellphone in April 2024 with an pressing scenario.

“We’ve obtained one thing that’s form of an enormous deal,” he remembers saying.

Throughout a routine check of a producer’s merchandise, Bona Fides Laboratory in Denver had discovered a poisonous chemical in a well-liked model of marijuana vapes offered at dispensaries in Colorado. The chemical, methylene chloride, is prohibited by Colorado’s marijuana regulators and for many makes use of by the U.S. Environmental Safety Company as a result of it may trigger liver and lung most cancers and harm the nervous, immune and reproductive programs. The proprietor felt he had an obligation to name instantly somewhat than simply submit a report by way of the state’s on-line system.

As state regulators investigated, they found a second drawback: The product wasn’t derived from marijuana in any respect. It got here from hemp, an in depth cousin of marijuana that’s less expensive to supply and that Colorado had banned corporations from utilizing to make intoxicating merchandise on the market within the state. 

Congress had legalized hemp in 2018 for different makes use of, equivalent to clothes and cord, and since folks imagine its excessive ranges of the nonintoxicating compound CBD will help them with seizures, ache and sleep. Hemp has extraordinarily low ranges of THC, the psychoactive compound present in marijuana that will get folks excessive. And federal lawmakers thought permitting it will assist farmers and rural jobs with out the dangers posed by marijuana. 

However hemp producers shortly found out convert CBD into THC by way of a course of that entails poisonous solvents, creating merchandise that generally include dangerous chemical substances and that may be stronger than merchandise constructed from marijuana.

Colorado was one of many first states to ban intoxicating hemp merchandise made by chemical processing, initially with regulatory advisories after which with laws in 2023. In doing so, lawmakers and Gov. Jared Polis boasted that Colorado — which had created the primary regulated leisure marijuana market within the nation — was as soon as once more a mannequin for neatly regulate hashish, producing billions of {dollars} in tax income whereas protecting shoppers protected.

However regardless of the ban, the legislature and regulators did not undertake many crucial rules that different states have employed to maintain hemp merchandise off the cabinets. 

Not like another states, Colorado’s lab testing system operates largely on an honor code, with marijuana producers free to decide on the samples they ship for evaluation. Colorado gained’t require labs to check these merchandise for the poisonous chemical substances used to transform hemp to THC till this summer time. The state can be now scrambling to arrange its personal testing program to randomly buy merchandise from dispensaries to confirm security.

The 2023 regulation additionally had an exception that allowed registered hemp corporations to proceed manufacturing intoxicating hemp merchandise, however just for sale exterior the state. Thuy Vu, a compliance guide who as soon as spearheaded town of Denver’s marijuana manufacturing inspection routine, warned lawmakers on the time that the carve-out “was an open invitation for unhealthy actors” that might lead to “misbranded merchandise” proliferating in Colorado.

The cumulative impact of those gaps means hemp-derived vapes, gummies and different edibles, which can be extra harmful than conventional marijuana merchandise, are making their solution to shoppers in Colorado, in line with regulatory filings, impartial testing and lab outcomes filed in litigation towards corporations and the state.

Evaluating Marijuana and Hemp

Officers with the state Marijuana Enforcement Division declined requests for an interview. Company spokesperson Heather Draper stated in an announcement that the company updates its testing program on “a virtually annual foundation” and “intends to pursue extra regulatory updates to the testing program this 12 months.”

She stated the division continues to research allegations of corporations utilizing hemp-derived THC in marijuana merchandise however famous that the inquiries take time as a result of “they are often extremely advanced and require vital sources to finish.”

After the passage of the 2018 federal farm invoice, many states have been caught off guard as folks may purchase hemp-derived vapes and gummies just like marijuana merchandise on-line or at gasoline stations throughout the nation, generally with out age restrictions.

That sparked security considerations as calls to poison management facilities and emergency room visits associated to recognized hemp merchandise surged.

“When you have got a market that’s unregulated, tough to evaluate and evolves in a short time, that could be a calling card for nefarious brokers to step in and generate income,” stated Michelle Peace, a toxicologist at Virginia Commonwealth College. “So, if they will make one thing which may have somewhat bit higher of a kick, why not?”

With considerations mounting and states making a hodgepodge of guidelines governing intoxicating hemp, Congress handed a regulation in November banning almost all hemp-derived merchandise beginning within the fall of 2026. However how the federal government will implement that’s an open query. In December, President Donald Trump issued an govt order to extend medical marijuana and CBD analysis, tasking his aides to develop rules with Congress that might permit some hemp merchandise whereas barring people who pose severe well being dangers.

For now, it stays as much as the states to control hemp. And Colorado’s expertise underscores how tough that process is. The hemp derivatives have jeopardized a key promise made to the state’s voters: that marijuana legalization would drive out the black market and create a safer atmosphere by way of regulation.

With hemp, the alternative has occurred, marijuana business representatives say.

Following the lab proprietor’s warning in April 2024, it took state regulators about two months to difficulty a public well being advisory concerning the poisonous vapes. The once-prolific vape producer surrendered its marijuana license in January 2025. Final 12 months, state regulators suspended two extra marijuana operators after discovering they used hemp-derived THC in merchandise.

The Denver Gazette and ProPublica performed their very own testing on merchandise bought at authorized hashish dispensaries in August and September. Three of the 14 vape merchandise examined contained compounds and chemical residues that a number of specialists stated have been indicative of hemp. A fourth vape had a solvent typically used to course of hemp into THC.

The instances of producers swapping marijuana for hemp have threatened Colorado’s marijuna business a lot that many corporations are calling for harder regulation. One even sued the state, asking a choose to pressure the Marijuana Enforcement Division to overtake its testing routine. In court docket filings, the company argued that altering testing protocols was pointless and impracticable.

“The honour system shouldn’t be working in Colorado,” Justin Trouard, proprietor of Mammoth Farms, the biggest marijuana cultivator within the state, stated within the lawsuit. “The robust financial incentives for hemp inversion have made it widespread follow in Colorado.”

“The Marijuana ‘Items’ Have Modified”

Colorado appeared well-prepared to tackle hemp after the world’s first shops licensed to promote marijuana opened there in 2014. 

The state developed a “seed-to-sale” system to trace marijuana from the preliminary planting  to the acquisition of pot, vapes and different merchandise in dispensaries, which was meant to calm fears that marijuana grown in Colorado can be diverted to states the place it remained unlawful. Colorado additionally arrange licensed personal labs to check marijuana merchandise for contaminants and efficiency. The monitoring and testing turned foundational parts that different states regarded to after they arrange their very own legalization packages. 

The primary wake-up name for Colorado marijuana regulators about intoxicating hemp got here in 2021.

A Broomfield man, whose enterprise used marijuana to make the honey-colored syrup referred to as distillate that goes into vapes and gummies, reported that one other firm, Mile Excessive Distributing, was making distillate from hemp and promoting it as a marijuana product.

Mile Excessive’s proprietor, Jeffry Knight, who ran a string of Florida nightclubs and eating places, had teamed up with retired pharmaceutical business chemist Harold Meckler to give you a solution to convert hemp CBD into extremely potent and worthwhile THC distillate for a fraction of what it value to make use of marijuana, in line with patents, a state investigation and interviews with Knight and Meckler.

After investigating the criticism, Colorado’s Marijuana Enforcement Division sought to bar Mile Excessive from taking part within the state’s marijuana business, arguing the corporate had used solvents and a chemical conversion course of that weren’t allowed to make a brand new hemp-derived focus for merchandise offered in marijuana dispensaries.

On the suspension listening to, Meckler testified that Mile Excessive’s hemp distillate was “most likely safer” than what you get from “Mom Nature,” stressing that distillation ought to take away any chemical substances used within the course of.

However Heather Krug, then Colorado’s state hashish sciences program supervisor, fearful that didn’t happen and testified on the listening to concerning the risks posed if chemical residue remained within the remaining product. “If you inhale one thing,” she stated, “it tends to go straight into your lungs and into your bloodstream and goes proper to your mind.”

Denver Hearth Division officers expressed concern that if the chemical substances inside Mile Excessive caught hearth or exploded, a plume of poisonous gasoline would have reached 1 to 2 miles over Denver neighborhoods, in line with a simulation run by the division’s hazmat crew.

“A brand new breed of marijuana focus has entered Colorado’s hashish market,” state listening to officer Milla Lishchuk stated in her suspension order, warning that the state had did not sustain with the altering business. “Primarily, the marijuana ‘items’ have modified within the hashish market, however the legal guidelines — at the least in Colorado — haven’t.”

She suspended Mile Excessive’s marijuana manufacturing license for 3 years, and the corporate went out of enterprise. 

In an interview, Knight stated that after his suspension, he had checks performed on a few dozen merchandise from Colorado dispensaries and located that two-thirds of them have been hemp derivatives. He stated his rivals merely stole his firm’s patented methods and have been doing what he was suspended for.

“There’s a bunch of fellows in Colorado which are making it illegally,” Knight stated within the interview. (Knight is going through prison costs in Florida after a deadly boat crash final 12 months. He has pleaded not responsible.)

Knight and Meckler contend that they didn’t endanger anybody with Mile Excessive merchandise however that the chemical conversion course of may very well be harmful within the improper arms. “There’s lots of people that don’t know what they’re doing,” Meckler stated.  

Mile Excessive’s case prompted Colorado regulators to difficulty warning bulletins about hemp-derived THC in 2021, but it surely took state lawmakers almost two years earlier than they handed laws that confirmed regulators may ban the sale of intoxicating hemp merchandise in Colorado.

By then, the hemp business was already entrenched in Colorado. It had invested over $300 million within the state and generated $800 million in annual revenues, in line with one business estimate given to lawmakers. It’s unclear how a lot of that’s intoxicating merchandise. However an business skilled instructed a legislative process pressure that Colorado had turn into “the most important supplier of hemp-finished merchandise in North America.”

Intoxicating hemp merchandise have been additionally spreading broadly throughout the nation. A number of states took motion. Oklahoma, for instance, launched a secret-shopper program to make sure correct labeling for its sanctioned medical marijuana merchandise, together with checks to detect banned solvents.

Different states that had adopted Colorado’s lead in full marijuana legalization have since adopted extra strong measures that Colorado didn’t. Of the 43 regulated leisure and medical marijuana markets in states and the District of Columbia, 24 require testing for methylene chloride.

Federal well being officers additionally started to sound the alarm. The Facilities for Illness Management and Prevention posted a public warning concerning the dangers of hemp-derived THC in 2021 after a spike in hospitalizations, together with kids who had consumed hemp gummies.

The next 12 months, the Meals and Drug Administration warned that hemp that had been chemically transformed into THC “could have doubtlessly dangerous by-products (contaminants) because of the chemical substances used within the course of.”

And research discovered THC merchandise derived from hemp prompted extra hurt than marijuana. A evaluation of FDA information from 2018 to 2021 discovered triple the variety of opposed occasions tied to delta-8 THC, a compound widespread in merchandise chemically derived from hemp, as that in delta-9 THC, the model present in marijuana.

Like different states, Colorado requires marijuana producers to have labs check their merchandise to make sure security. Twenty-six states and the District of Columbia require lab personnel to gather samples for testing to make sure that producers don’t cherry-pick merchandise for testing and maintain again contaminated merchandise. 

However Colorado lets producers choose samples for testing. The state discovered two dozen instances wherein corporations had manipulated testing in 2024 alone, in line with a evaluation of Marijuana Enforcement Division stories. The violations ranged from substituting samples that have been totally different from what corporations offered in shops to using unauthorized chemical therapies on submitted samples.

In an April court docket submitting within the lawsuit introduced by Mammoth Farms, the division stated it noticed no motive to require testing for methylene chloride because it’s already banned and that doing so can be “unreasonably impracticable.” The company’s attorneys stated state workers couldn’t accumulate samples for testing as a result of they’re barred from possessing managed substances, however the submitting didn’t say why personal labs couldn’t collect them.

Marijuana business officers say this resistance by regulators has made it simpler for producers to cheat through the use of hemp-derived distillates. In addition they say the dearth of regulation makes it arduous to detect whether or not the distillate they purchase is derived from hemp.

“It has by no means been cheaper to get the outcomes that I need and dearer to get an correct understanding of what’s in my stock,” Justin Singer, CEO of Denver-based hashish firm Ripple, stated at a current coverage discussion board. “Should you really need an correct quantity, you can not get one at present if you happen to care about accuracy. Should you simply care about passing the check, you will get that for 120 bucks.”

Take a look at Outcomes Increase Suspicions

The gaps in Colorado’s marijuana legal guidelines have allowed hemp to maintain displaying up all through the market. Again and again, Colorado has issued late warnings to the general public or delayed enforcement motion, even when officers have been conscious of the violations.

The most important discovery of unlawful hemp merchandise occurred with the contaminated vapes that Bona Fides Laboratory referred to as about in April 2024. However it wasn’t the primary time Colorado regulators had heard considerations concerning the firm, Ware Hause. In October 2023, a whistleblower warned the Marijuana Enforcement Division that Ware Hause was chemically changing hemp to make intoxicating vapes and promoting them as marijuana.

The state opened an investigation after the 2023 report, however regulators didn’t warn the general public till June 2024, a few months after the lab reported the optimistic checks for methylene chloride. The Marijuana Enforcement Division instructed shoppers to destroy or return Ware Hause vapes purchased as many as 5 months earlier. The company decided that samples Ware Hause had submitted for testing weren’t consultant of what it put out to market. 

Ware Hause’s proprietor, Thanh Hau, declined requests for an interview and didn’t reply to detailed questions.

The issue was extra widespread than Ware Hause, in line with Mammoth Farms, which grows marijuana and has loads to lose if hemp infiltrates the market. The corporate sued Ware Hause and three different producers final 12 months, claiming that impartial testing confirmed their vapes contained distillate derived from hemp.

Mammoth Farms argued that the low-cost hemp put shoppers in danger and in addition put it and different corporations at a aggressive drawback. The businesses have denied the allegations, and Ware Hause countersued, contending that Mammoth Farms was the one utilizing hemp derivatives to make distillate, an allegation Mammoth Farms denied.

For now, Colorado doesn’t have a testing routine to detect hemp to assist type out such conflicts.

In March, Mammoth Farms filed one other lawsuit towards the Marijuana Enforcement Division, arguing that the testing system and seed-to-sale monitoring program have been failing to catch impostor merchandise derived from hemp.

Throughout a court docket listening to in that case final spring, an official for Purplebee’s, as soon as the biggest marijuana distillate producer in Colorado, stated hemp distillate was making it arduous to show a revenue. James Parco, former president of producing, stated the value of distillate had cratered to $2 a gram. That was down 85% from what testimony in one other case estimated it had been 4 years earlier, and he stated the decline pressured his firm out of the distillate enterprise.

The choose dismissed the lawsuit towards the enforcement division in Might on procedural grounds, stating that Mammoth Farms ought to have petitioned regulators for rule adjustments earlier than submitting the go well with.

Regulators have since discovered different hemp instances. The Fee Cartel, a marijuana producer, surrendered its license in July after the Marijuana Enforcement Division discovered vials of hemp-derived compounds in a fridge on the manufacturing unit it was utilizing. 

One of many firm’s house owners, Joshua Littlejohn, denied in an interview that the corporate used hemp in its edibles and stated it had as an alternative used hemp to fabricate physique lotions for an additional firm, which state regulators stated nonetheless wasn’t allowed as a result of the hemp had intoxicating ranges. He stated he surrendered his license as a result of preventing regulators would value an excessive amount of.

Colorado regulators have began taking steps to undertake rules that different states have, with a trial of an off-the-shelf testing program to purchase merchandise from dispensaries and double-check the work of labs. 

In addition they agreed to require testing for methylene chloride earlier than any merchandise can go to dispensaries. Nonetheless, the state delayed implementation till July to present labs time to regulate their practices.

“It’s not sufficient,” stated Singer, the proprietor of Ripple. “It’s a begin. However like, once more, they’re 4 years late at the least.”
