Tetrahydrocannabinolic acid (THCa) is a naturally occurring cannabinoid found in raw cannabis. THCa itself is non-psychoactive — meaning it will not get you “high” in its natural state. Instead, THCa is the precursor to THC, the compound known for cannabis’s intoxicating effects.
When cannabis flower is heated through smoking, vaping, or cooking, THCa undergoes decarboxylation and converts into THC. This is why raw cannabis won’t cause intoxication, but THCa-rich hemp flower becomes psychoactive once consumed with heat.
Yes. THCa flower is federally legal under the 2018 Farm Bill as long as it is derived from hemp and contains less than 0.3% delta-9 THC on a dry weight basis. Because THCa itself is not delta-9 THC, THCa hemp flower can be legally purchased in Missouri.
However, once THCa is heated and turns into THC, it has the same psychoactive effects as cannabis from a dispensary. The key difference is that hemp-derived THCa flower meets federal compliance standards, making it legally available outside Missouri’s licensed cannabis dispensaries.
THCa became legal through the 2018 Agricultural Improvement Act (Farm Bill), which federally legalized hemp and hemp-derived cannabinoids. While the law does not specifically name “THCa,” its legality is based on hemp’s definition: cannabis with no more than 0.3% delta-9 THC.
This legal framework is what allows THCa flower to be grown, sold, and shipped across the U.S., including Missouri.
