The principal active component of which drug is THC?

• A. Benzodiazepine
• B. Marijuana
• C. Morphine
• D. Codeine

Answer: (B)

THC, or delta-9-tetrahydrocannabinol, is the primary psychoactive constituent of cannabis, the drug commonly called marijuana. It produces the characteristic “high” by activating cannabinoid receptors in the brain (especially CB1 receptors), which modulates neurotransmitter release and affects perception, mood, and cognition. The other options represent different drug classes with their own distinct active ingredients (benzodiazepines are sedatives acting on GABA-A, while morphine and codeine are opioid analgesics). For these substances, THC is not the principal active component. Therefore, marijuana is the drug in which THC is the principal active component.
