  • California touts $544 million in illegal weed seizures. Drop in the bucket, exasperated officials say

    California touts $544 million in illegal weed seizures. Drop in the bucket, exasperated officials say

    Two major state programs to combat illegal cannabis recently sent out news releases lauding their collective seizures of some $544 million worth of illicit weed.

    But when it comes to reining in California’s sprawling black market, experts say it’s just a drop in the bucket.

    Those in the thick of the fight against illegal pot, like Mendocino County Sheriff Matthew Kendall, can’t help but roll their eyes.

    “Don’t get me wrong, I love when those guys [state law enforcement officers] show up to help,” he said, “but I would need 50 police officers for 50 days to even begin putting a dent in it.”

    So far this year, an estimated $353 million worth of illicit plants have been seized through a California Department of Justice program, while a task force with the governor’s office has seized an estimated $191 million.

    Despite these alarming numbers, some law enforcement leaders say the raids are barely slowing the black market — which, according to a study by Beau Whitney, founder of cannabis economics research firm Whitney Economics, makes up more than half the state’s marijuana sales.

    “If we examine the statistics, it is clear that these operations are not effectively or aggressively putting a dent into the illegal market,” said Siskiyou County Sheriff Jeremiah LaRue.

    For example, operations by the state Department of Justice’s Eradication and Prevention of Illicit Cannabis program, or EPIC, have seized about 77,000 cannabis plants in 36 counties this year. Yet, Siskiyou County alone produces an estimated 12 million to 16 million illegal plants per year. Therefore, if EPIC only focused on Siskiyou for a year, it would eradicate just 6% of the estimated local black market, he said.

    This sentiment was echoed by Kendall, who noted that in Mendocino County’s 35-square-mile Round Valley alone there are an estimated 1 million illegal marijuana plants.

    “The black market is as big and bad as ever,” he said.

    The Riverside County Sheriff’s marijuana enforcement team told The Times there is still a lot of work to do to address that county’s black market, which has not gotten any smaller in the last two years.

    In 2022, a Times investigation found that California’s massive illegal marijuana market pushes legal growers toward financial ruin, exacerbates community violence, causes massive amounts of environmental degradation and forces laborers to toil in squalid and often dangerous conditions.

    Since then, many law enforcement leaders say they believe the state has done little to address the problems fueling the black market — onerous taxation and regulations for legal producers, few consequences for illegal operators and limited access to legal marijuana in wide swaths of California.

    “It’s like [state leaders] came to our counties, they sprayed the whole thing with gasoline and lit it on fire,” Kendall said. “Then they start talking about EPIC doing this work that is basically showing up with a garden hose.”

    A spokesperson for Gov. Gavin Newsom referred questions about the concerns raised by local law enforcement leaders to the state Department of Cannabis Control, which did not respond to a request for comment.

    California legalized weed through Proposition 64, a 2016 ballot measure that promised “to tax the growth and sale of marijuana in a way that drives out the illicit market.” Eight years later, the illicit market continues to thrive.

    “California did a horrible job of incentivizing [illegal] cultivators to convert over,” said Whitney, the cannabis economist. “They taxed them heavily, they regulated them heavily, they couldn’t make any money.”

    California charges a 15% excise tax on marijuana sales on top of additional local marijuana taxes. A recent study by cannabis industry research and analysis firm GreenWave Advisors found that legal weed companies owe the state more than $730 million in back taxes, 72% of which is owed by companies that have gone out of business.

    Another challenge is that more than half of California counties don’t allow the sale of marijuana, which restricts access to legal weed in wide swaths of the state and drives demand to the black market.

    There are also major incentives for sellers to opt into the illegal market — they can dodge taxation and licensing fees, while knowing that the penalty for selling or transportation of marijuana without required licenses is only a misdemeanor.

    “From the criminal mindset, there is minimal downside and massive upside to cultivating marijuana illegally and selling it on the black market,” said San Bernardino County Sheriff’s Lt. Larry Lopez.

    Siskiyou County Sheriff LaRue said that, although there are enhanced penalties for certain violations involving tax evasion and environmental crimes, most of the illegal-cultivation offenses do not have harsh enough penalties to deter production.

    Because enforcement measures are limited, Mendocino County Sheriff Kendall said the raids conducted by state agencies are like a game of Whac-A-Mole.

    “We can chop it down and, by golly, it pops up again the next day,” he said.

    Raids are also a limited enforcement tool, because they mostly lead to the arrest of laborers — not owners.

    “It is a frequent strategy for the black-market organizers to hide behind the labor force and remain shielded from law enforcement,” LaRue said. “It is rare that higher-level organizers are anywhere near the cultivation areas.”

    Despite the drawbacks and frustrations, Sheriffs LaRue and Kendall and Lt. Lopez still support conducting raids and welcome state assistance.

    But they say that, to have a meaningful effect, raids need to be accompanied by policy changes that address the narrow profit margin for legal cultivators and the minor penalties for illegal ones.

    And after years of calling for change, there’s a growing sense of exasperation among those on the front lines.

    “We have reached a time in the state of California where the architects of these laws — the governor, the legislators — they’re refusing to speak with the carpenters, and that’s the sheriffs and the police chiefs,” Kendall said. “When we say this isn’t going to work, it’s falling on deaf ears.”

  • New Study on Metals in Weed Vapes Presented by Researchers | High Times

    New Study on Metals in Weed Vapes Presented by Researchers | High Times

    In a study published in ACS Omega last November, researchers discovered that both legal and illegal vape pen liquids contained metal nanoparticles, including copper, zinc, lead, nickel, chromium, and more.

    The study was funded by Health Canada and conducted by the National Research Council of Canada. Researchers presented their findings at the American Chemical Society (ACS) meeting that was held between March 17-21 in New Orleans, Louisiana, which included almost 12,000 presentations on a wide variety of different subjects.

    Andrew Waye, who’s in charge of the research program at the Health Canada Office of Cannabis Science and Surveillance, presented the results of the study at the meeting. “Cannabis vapes are newly regulated products in Canada, so we don’t yet have much scientific data about them,” Waye said in a press release. “This is an opportunity for us to look at some of the questions concerning the risks and unknowns of cannabis vapes.”

    Lighting a cigarette combines tobacco (the fuel) and oxygen to begin a combustion process that burns through the tobacco. The process of vaping doesn’t utilize a combustion process, and instead heats the liquid until it becomes an inhalable vapor. Between cigarettes and vaping, vaping is often seen as safer, but researchers cautioned this opinion due to the presence of metals that can still be present in the vapor that is inhaled.

    The study primarily focused on whether or not cannabis vapes in particular also contained nano-sized metals. Using 41 different cannabis vape liquids (20 of which were legal products, and 21 were illegal samples provided by the Ontario Provincial Police), researchers utilized mass spectrometry to find and analyze a variety of contaminants. 

    Researchers worked with Zuzana Gajdosechova, who works at the Metrology Research Centre of the National Research Council of Canada, to analyze the samples and determine if they contained any of 12 metals that can be viewed via electron microscopy. The press release explained that metals such as arsenic, mercury, and cadmium were present, but within acceptable limits. However, some illegal samples contained more lead than is legally permitted. “The presented data from legally purchased and illegal cannabis vape devices showed mass fractions of Pb above the currently established tolerance limits in several of the vape liquids analyzed, particularly in the illegal samples where Pb [lead] concentrations were up to 100 times higher than the limit,” the authors wrote. “Additionally, the measured mass fractions of toxic metals such as Cr [chromium], Cu [copper], Ni [nickel], and Co [cobalt], as well as the essential metals Zn [zinc] and Mn [manganese] that have known inhalation toxicity, add to the existing evidence that long-term vaping may carry risks to health.”

    The samples were taken from vapes that were less than six months old and had never been opened or used. “The evidence strongly suggests that metal contamination can come from the device when it’s produced, and not from the heating of the coils,” Gajdosechova said. “But depending on the quality of the device, the contamination may be increased by that heating.”

    The study showed that the most common heating elements usually include nichrome, copper-plated brass, and kanthal, while the metal components of atomizers (the wick and coil in a vape pen) are made from stainless steel and tin, and lead is used as a solder.

    This prompted researchers to reconsider testing procedures in Canada. “If contamination is happening when the device is assembled, you should be testing at that stage rather than earlier,” said Waye.

    Through single particle inductively coupled plasma mass spectrometry, the research team also found that metal particles were nano-sized. “Some nano-sized metal particles are highly reactive and potentially harmful,” said Gajdosechova.

    The next step would be to analyze how much of those harmful, nano-sized metals are transferred into the vapor. This could reveal even more about the potential harm of metals entering the lungs when inhaled. “Different types of cannabis products present different risks,” said Waye. “Our research doesn’t answer whether vaping is riskier than smoking, it just underlines that the risks may be different. Previously uncharacterized risks with cannabis vaping are still being identified.”

    Research conducted by New York’s Columbia University last year found that cannabis and tobacco consumers had higher percentages of lead and cadmium in their blood and urine compared to non-users of tobacco and cannabis. Scientists explained that long term exposure to lead and cadmium could lead to health issues such as cardiovascular disease, chronic obstructive pulmonary disease, cognitive impairments, or an increased risk of cancer. “We found overall associations between internal metal levels and exclusive marijuana use, highlighting the relevance of marijuana for metal exposure and the importance of follow-up studies to identify the long-term implications of these exposures,” researchers said in their conclusion. They also called for more research in order to assess the presence of other contaminants and health impacts to protect the general public.
