What is THCA and Delta-9-THC?

THCA (tetrahydrocannabinolic acid) and Delta-9-tetrahydrocannabinol (Delta-9-THC) are two compounds found in the cannabis plant, and they play crucial roles in the effects associated with cannabis consumption.

THCA (Tetrahydrocannabinolic Acid)

THCA is the non-psychoactive precursor to THC found in raw cannabis plants. In its natural state, cannabis produces THCA rather than THC.

When cannabis is harvested and dried, THCA slowly converts to THC through a process called decarboxylation. This process is often triggered by heat, such as smoking, vaporizing, or baking.

THCA itself doesn't produce the characteristic psychoactive effects commonly associated with cannabis use. Instead, it has potential anti-inflammatory and neuroprotective properties. Some people consume raw cannabis or cannabis juices to access the potential health benefits of THCA without experiencing the typical "high" associated with THC.

Delta-9-Tetrahydrocannabinol (Delta-9-THC)

Delta-9-THC is the primary psychoactive compound in cannabis responsible for the "high" or euphoric feeling that people experience when they consume cannabis.
When cannabis is heated (through smoking, vaping, or cooking), the decarboxylation process converts THCA into Delta-9-THC, which is then absorbed into the bloodstream and reaches the brain.
Delta-9-THC interacts with the endocannabinoid system in the body, particularly with CB1 receptors, leading to various effects such as altered perception of time, changes in mood, and increased appetite.

Federal Regulation

Cannabis, including its compounds like THC and THCA, is classified as a Schedule I controlled substance under the Controlled Substances Act (CSA) at the federal level. This means that, according to federal law, cannabis is considered to have a high potential for
abuse and no accepted medical use.
The Farm Bill of 2018 legalized hemp-derived products containing less than 0.3% THC on a dry weight basis. However, the focus of this legalization was on Delta-9-THC, and specific regulations regarding THCA may vary.
