What metabolite is derived from THC?

The correct answer is carboxy THC. When tetrahydrocannabinol (THC), the primary psychoactive compound in cannabis, is metabolized in the body, it undergoes various chemical changes, one of which produces carboxy THC. This metabolite is significant in drug testing, as it is often detected in urine and indicates past cannabis use. Carboxy THC is the inactive form of THC and remains detectable in the body's system for an extended period after the initial effects of THC have worn off.

Hydroxy THC, while also a metabolite of THC, is generally active and contributes to the psychoactive effects of cannabis, thus making it less relevant as the primary metabolite when identifying THC's breakdown products. The term "metabolite THC" is not commonly used in pharmacology or toxicology discussions, and "active THC" misrepresents the inactive nature of the carboxy metabolite derived during the metabolic process. Understanding these metabolic processes is crucial for effective interpretation of drug tests and the physiological effects of THC.
