THCa hemp flower consists of cannabis buds with high THCa levels and less than 0.3% delta-9 THC, meeting the legal definition of hemp under the 2018 Farm Bill. THCa is a non-psychoactive compound that converts into THC when heated, which may produce intoxicating effects.

While legal federally, some states regulate both THCa and THC levels (known as “total THC”) to classify hemp products. Always check your local laws before selling or possessing THCa flower. The DEA recognizes hemp products with less than 0.3% delta-9 THC as lawful, regardless of THCa content.

THCa hemp flower can trigger positive drug test results since THC is present. For this reason, it’s not recommended for individuals subject to testing.

Federal law allows hemp, including THCa flower, to be shipped across state lines, even if state regulations differ. To avoid legal misunderstandings, avoid smoking it in public or transporting it in open packages.

To remain compliant, review the product’s Certificate of Analysis (COA), which confirms cannabinoid levels. Proper storage is essential—keep the flower in a cool, dry place to prevent conversion of THCa into THC through exposure to heat or light.
