Branford resident Alex London uses cannabis to help with lingering back pain and migraines that stem from a car crash.
London said he used to buy it from medical marijuana dispensaries near his home. But now, because of changes in how 海角换妻 regulates cannabis, he鈥檚 back to using his 鈥渓ocal guy鈥� 鈥� a grower in Maine.
鈥淎t least with him, I鈥檓 aware of where it comes from,鈥� London said.
That matters for London because he鈥檚 worried about the amount of mold in the marijuana he smokes.
Mold is present wherever we go: It鈥檚 in our food, our medicine and our air. Because avoiding mold entirely is impossible, the U.S. Food and Drug Administration allows for small amounts of it in lots of consumer products. But because marijuana isn鈥檛 legal at the federal level, it鈥檚 up to states to decide how much mold in the product is too much.
And in 海角换妻, that limit has been in flux. It鈥檚 currently set at 100,000 colony-forming units per gram of cannabis (a measurement expressed as CFU/g). A review by The Accountability Project found that that鈥檚 10 times higher than the threshold in most other states that have a numeric limit for mold in marijuana.
London said his decision to procure medical marijuana elsewhere was driven by his desire to protect his own health. Mold poses a bigger risk for medical marijuana patients who are older or have compromised immune systems.
鈥淚 feel like there鈥檚 still a lot of people that aren鈥檛 aware of the fact that these standards have changed,鈥� he said.
When medical marijuana was legalized in 海角换妻 in 2012, the acceptable standard was less than 10,000 CFU/g. But, in 2021, the state Department of Consumer Protection (DCP) approved a request from one of the state鈥檚 testing facilities, AltaSci Laboratories, to increase the threshold to 1 million CFU/g.
State regulators have since rolled back the limit to 100,000 CFU/g, where it now stands.
Meanwhile, Northeast Laboratories, the only other lab that tests for mold in marijuana in the state, kept its standard 10 times lower. Neither lab responded to requests for comment.
DCP did not address the reasoning behind its shifting guidelines, but the agency said in a statement that the most recent change was drafted in consultation with independent microbiologists and regulators in other states and that it represents industry best practices from across the country.
The agency also said it requires tested samples to contain no detectable traces of specific strains of mold or yeast that may be harmful to humans, specifically aspergillus, a fungus that can cause an infection in the lungs.
海角换妻 is joined only by Florida and Maryland in setting the mold limit as high as 100,000 CFU/g. But safety standards vary widely across the nation. Some states don鈥檛 measure mold levels at all, and some look only for specific, dangerous molds, operating on a pass-fail system.
鈥淸海角换妻鈥檚 standard] isn鈥檛 as rigorous as some would like, but it is a modest level,鈥� said Michael White, a distinguished professor at the UConn School of Pharmacy. 鈥淚t can give people a moderate sense of security when they're using these types of products.鈥�
Patients should consult with their doctors about risk associated with mold, said Cassin Coleman, vice chair of the scientific advisory committee at the National Cannabis Industry Association, an industry group. But in general, most mold in marijuana is not more dangerous than other common mold exposures.
鈥淚f a medical patient in 海角换妻 can have pain as the reason that they they鈥檙e getting cannabis, unless they have some other underlying immune compromising [condition], you鈥檙e not talking about things that are going to be any worse off than if you were walking down the street,鈥� Coleman said.
As part of The Accountability Project鈥檚 research, we asked MCR Labs in Massachusetts to test a sample of marijuana from a dispensary in 海角换妻. It came back showing 100 CFU/g of mold 鈥� well below the cutoff in both Massachusetts and 海角换妻.
Michael Kahn, CEO of MCR Labs, said it鈥檚 evident that the marijuana safety regulatory system is piecemeal.
鈥淲e really do have a state-by-state-by-state experiment, I guess, in public health,鈥� he said. 鈥淚 just wish that the states would talk to each other more and adjust their regulations based on each other鈥檚 data.鈥�
EDITOR'S NOTE: After publication, this article was updated to reflect a statement from DCP which says the following: "The laboratory standard codified in regulation in 海角换妻 as of July 2021 is 100,000 CFU/g and no detectable traces of specific strains of mold or yeast that may be harmful to humans, specifically aspergillus."
