Took wording of post from bears bros farms directly off ig.
A friend sent me an article this morning from Marijuana Moment that discusses a May 13, 2024 letter to my friend and colleague, attorney Shane Pennington, regarding the legal status of THCa.
Apparently, Shane reached out to the DEA inquiring about the status of THCa. In its response, by Dr. Terrence Boos, the DEA’s Chief of its Drug and Chemical Evaluation Section, states:
“In regards to THCA, Congress has directed that, when determining whether a substance constitutes hemp, the delta-9 THC concentration is to be tested “using post-decarboxylation or other similarly reliable methods.” 7 USC § 1639p(a)(2)(A)(ii); 7 USC § 1639q(a)(2)(B). The “decarboxylation” process converts delta-9 THCA to delta 9 THC. Thus, for the purposes of enforcing the hemp definition, the delta-9 THC level must account for any delta-9-THCA in a substance. Accordingly, cannabis derived THCA does not meet the definition of hemp under the CSA because upon conversion for identification purposes as required by Congress, it is equivalent to delta-9 THC.“
This is almost verbatim what Dr. Boos said in a June 9, 2023 letter about THCa that I blogged about almost a year ago.
In short, the DEA is correct with respect to pre-harvest hemp testing, which requires a post-decarboxylation (ie, total THC) test, but the DEA is incorrect with respect to harvested cannabis material. This is because the two statutes it cites in support of its position are the only two places in the Farm Bill that discuss “post-decarboxylation”.
They are both in the context of hemp “production”, which is defined as cultivating hemp. Once the mandatory pre-harvest testing is completed, a hemp crop may be harvested if it passed the test. Thereafter, the statute solely refers to “delta-9 THC”, not “THC” or “post-decarboxylated delta-9 THC” or anything else. The statute just says “delta-9 THC”. In fact, the DEA has said as much on many prior occasions.
To be clear, this is a brief summary since I’ve already addressed this issue in depth. I encourage you to read my article from last summer for the more in-depth analysis.

Time for the industry to learn about the deep states reverse uno card they use on the supreme court. Just because your interpretation is correct textually doesn’t mean they are going to rule in your favor.
