Tetrahydrocannabinol monomethyl ether, commonly abbreviated to THCM, is a rare cannabinoid and isomer of THC-H. Both compounds have the same chemical formula (C22h32hey2) and molecular weight. Traces of THCM have been found in marijuana smoke and possibly in synthetic CBD e-liquid after degradation.
The THCM cannabinoid should not be confused with a test called THCM, which is used to detect exposure to cannabis during pregnancy. This test analyzes infant fecal matter for the presence of the THC metabolite THC-COOH. The THCM cannabinoid is unrelated to the test that uses that name.
At this time, it is extremely unclear whether or not it will even be possible to produce THCM cannabis products as the cannabinoid has not yet been isolated in hemp or marijuana due to chromatographic issues. In other words, chemists have not found a way to separate THCM from other cannabinoids or natural compounds in the cannabis plant using current chromatography techniques. The separation would not occur until chemists developed a new method. As things stand, they hardly know where THCM comes from.
Unlike THCM, the monomethyl ether forms of CBG and CBD (CBGM and CBDM) have been successfully isolated.
What are the effects of THCM?
We don’t know anything about the effects of THCM when consumed. It has no known benefits and users may or may not get benefits from it. No side effects have been documented.
Products claiming to contain THCM – which is controversial in itself – can still get you addicted. It is simply necessary to include other psychoactive cannabinoids. Whenever you purchase vape carts, disposables, or edibles containing multiple cannabinoids, be sure to research each compound individually.
Delta 9 THC and THCM are closely related to each other but have very few characteristics in common.
The heat generated by vaping or smoking marijuana converts the THCs precursor, THCA, into delta 9 THC; The smoke produced may then contain very small amounts of THCM. However, it currently does not appear that THCM is a metabolite of THC.
THCM is the monomethyl ether of THC. They have some structural similarities and are both made of hydrogen, carbon and oxygen. These two are not isomers, so their formulas and weights are different. Delta 9 THC contains one less carbon and two less hydrogens than THCM. Both have two oxygen atoms.
And that’s the extent of what we know about THCM. Because it was never isolated from the cannabis plant or extracted for use or consumption, it was not certain whether it was present in the plant or not. It can only be detected as a byproduct of THC degradation.
THC, on the other hand, occurs naturally in cannabis and has been extensively researched. Its effects and benefits have been analyzed and discussed for decades.
Nothing is known about the safety of THCM when consumed.
Although it is unlikely that true THCM products even exist, be sure to check the Certificate of Analysis (COA) before purchasing any product claiming to contain THCM. You likely won’t find THCM, but third-party testing can at least confirm that the product is free of contaminants.
Is THCM legal and where is it sold?
Theoretically, THCM products It is possible Legal for production and sale in the United States. As long as they are byproducts of direct extraction or conversion from naturally occurring hemp cannabinoids, they are protected under the 2018 Farm Bill, as long as they contain less than 0.3% delta 9 THC by dry weight.
However let’s address the bigger issue. The THCM cannabinoid has never been successfully isolated from cannabis, and it is unclear how much, if any, is found in natural plant material. As far as we can tell, it also has not been synthesized in a laboratory.
Third-party laboratories do not test for THCM. Actually, there doesn’t seem to be any way to accurately measure THCM content in the first place. Some products still claim to contain it. Most of these carts and disposables contain blends containing other cannabinoids.
Because it can’t be tested and won’t appear on the COA, there’s no way to know how much THCM is in a product. Based on the limited research available, it is highly unlikely that any commercial products contain actual THCM.
