THC, short for tetrahydrocannabinol, refers to the primary chemical compound responsible for cannabis’ euphoric effects. THC is a cannabinoid, which are compounds produced by the cannabis plant that bind uniquely to receptors in the body called endocannabinoid receptors. A majority of cannabis varieties are THC-dominant, meaning THC is the most abundant cannabinoid. THC-dominant cannabis typically contains anywhere from 10% to 30% THC. Although many factors contribute to the potency of cannabis, generally a higher THC percentage correlates with a more intense high.
