What is THC more formally known as?

THC is more formally known as Delta-9-tetrahydrocannabinol. This designation reflects its chemical structure and the specific location of a double bond in the carbon chain of its molecular formula. The "Delta-9" indicates that the double bond is located at the ninth carbon atom, a critical factor in understanding its pharmacological properties and effects.

This compound is the primary psychoactive component of cannabis, responsible for the "high" associated with marijuana use. The distinction of Delta-9-tetrahydrocannabinol is important in both medical and recreational contexts, as it is the most extensively studied and recognized form of THC. Understanding this specific nomenclature helps in discussions about cannabis legality, use, and the varying effects of different cannabinoids.

The other options represent different forms or concepts related to cannabinoids, but none are as widely recognized or relevant as Delta-9-tetrahydrocannabinol when discussing THC specifically. Delta-8-tetrahydrocannabinol, for instance, is a less common isomer with different effects. Cannabinoid-9 and Delta-cannabinoid are not standard terms used to refer to THC in scientific literature or discussions.
