THC-A, or tetrahydrocannabinolic acid, is a non-psychoactive cannabinoid found abundantly in raw cannabis plants. As the acidic precursor to THC, THC-A converts into the psychoactive THC when exposed to heat through processes such as smoking, vaping, or decarboxylation during cooking. In its raw form, THC-A possesses significant therapeutic potential, displaying anti-inflammatory, neuroprotective, and antiemetic properties, making it appealing for medical use without the intoxicating effects typically associated with THC.

Increasingly popular among health-conscious consumers, THC-A is commonly consumed through raw cannabis juices, tinctures, and topical applications, providing potential relief from inflammation, pain, nausea, and seizures, and sparking interest in its broader medicinal applications.
