Welcome to Cannabinoid Clinic, an education project powered by Higher Learning LV. This series provides cannabis and hemp industry professionals with easily digested cannabinoid profiles that ask little of your time—but provide plenty of science-based information.

There are two categories of cannabinoids: Phytocannabinoids and endocannabinoids. Phytocannabinoids are those produced by cannabis/marijuana/hemp, while endocannabinoids are made by the human body. This series covers both.

THCA molecular structure

What is THCA?

Tetrahydrocannabinolic acid (THCA) is the acidic precursor to the most infamous cannabinoid on earth, delta-9 tetrahydrocannabinol (THC). It is derived from the "mother of all cannabinoids," cannabigerolic acid (CBGA), which also produces the important cannabinoids cannabidiolic acid (CBDA) and cannabichromenic acid (CBCA).

Although not psychoactive, research has revealed that THCA delivers a wide range of potential medicinal benefits, including anti-inflammatory and anti-nausea properties. If decarboxylated with heat or a flame, THCA morphs into THC. This occurs when cannabis consumers vaporize or smoke the loose-leaf flowers of the plant.
