THC is the primary psychoactive ingredient in which substance?

• A. Depressants like valium
• B. Stimulants like cocaine
• C. LSD and ecstasy
• D. Marijuana

Answer: (D)

Think about what causes the characteristic “high” associated with cannabis. The key idea is that THC, short for delta-9-tetrahydrocannabinol, is the primary psychoactive compound found in marijuana. It’s the chemical responsible for most of the mind-altering effects people experience after using cannabis, because it strongly interacts with the brain’s endocannabinoid system, especially CB1 receptors. That interaction changes perception, mood, memory, and coordination. The other options point to entirely different drug classes and their typical active substances. A depressant like valium has a different primary chemical that slows brain activity; a stimulant like cocaine increases alertness and energy via another mechanism; LSD and MDMA (ecstasy) act as hallucinogens or entactogens with their own distinct primary substances. None of these are the primary psychoactive ingredient in marijuana, which is THC.
