Which substance is a primary psychoactive ingredient in cannabis?

• A. CBD
• B. THC
• C. Limonene
• D. Cannabinoid

Answer: (B)

The main concept tested is identifying which compound in cannabis is responsible for the psychoactive high. The primary psychoactive ingredient is THC, short for delta-9-tetrahydrocannabinol. THC binds to cannabinoid receptors in the brain (notably CB1), producing the altered perception, mood, and cognition that people associate with being high. CBD is another cannabinoid but does not generate strong intoxication and can even modulate some of THC’s effects. Limonene is a terpene that contributes to aroma and flavor rather than the intoxicating high. Cannabinoid is a broad class of compounds that includes THC and CBD, not a single substance driving the high.
