Is THCA Flower Legal in Michigan?

THCA hemp flower is illegal in Michigan because it doesn’t fall under the definition of hemp. 

State law defines ‘hemp’ as a crop with THC levels of 0.3% by dry weight. Furthermore, it includes tetrahydrocannabinolic acid (THCA) in the definition of THC, with THC being “any of the following:” 

  • Tetrhydrocannabinolic acid
  • A tetrahydrocannabinol, regardless if artificially or naturally derived
  • A structural, optical, or geometric isomer of tetrahydrocannabinol 

This means that the term THC includes THCA and other naturally or artificially derived THC isomers, like delta 8 and delta 10 THC. 

It also means that the state has a total THC standard for finished hemp products. Finished hemp products sold in retail stores are legal in Michigan if their total THC concentration (as defined above) doesn’t exceed 0.3% by dry weight. 

This makes most THCA hemp flower strains illegal in Michigan because the law takes into account the potential conversion of THCA into THC. Therefore, the law considers ‘hemp’ any product with THC levels of less than 0.3%, regardless of whether it’s derived from hemp or marijuana. 

While you can’t purchase THCA hemp flower in Michigan, you can buy regular cannabis flower. Since 2018, Michigan has allowed the sale, use, and possession of cannabis for medical and recreational purposes. If you’re 21 and older, you can possess up to 2.5 ounces of weed and grow up to 12 plants at home.

What is THCA Flower? 

THCA flower, a unique type of hemp flower, has an identical cannabinoid profile to marijuana flower, but it’s considered legal hemp. Tetrahydrocannabinolic acid, or THCA, is the primary compound in this type of flower. 

If not activated through heat, THCA is a biologically inactive cannabinoid that doesn’t cause an intoxicating feeling. However, heat decarboxylates THCA into delta 9 THC. 

So, when smoking THCA-rich products, like THCA flower, you consume delta 9 THC. This compound is the primary intoxicating cannabinoid in cannabis and will get you intoxicated. In summary, the volatile nature of this cannabinoid and its status as a precursor to THC stands behind its complex legal status.
