Which statement is true about psychoactivity in marijuana components?

• A. CBD is psychoactive
• B. THC is psychoactive
• C. CBD and THC both are psychoactive
• D. Neither

Answer: (B)

Psychoactivity from marijuana comes mainly from THC, the component that produces the classic high by binding to CB1 receptors in the brain and changing how neurons fire. That binding alters mood, perception, and cognition, which is why THC is considered psychoactive. CBD, on the other hand, does not cause intoxication in the usual sense; it has little direct action at CB1 receptors and tends to modulate other effects instead. So the true statement is that THC is psychoactive. The idea that CBD is psychoactive or that both are, or that neither is, doesn’t fit the science, since THC reliably produces psychoactive effects while CBD does not.
