Which term is used for the class of drugs that includes marijuana and is known for altering perception and mood?

• A. Stimulants
• B. Consolidation Theory
• C. Psychoactive Drugs
• D. Opioids

Answer: (C)

Psychoactive drugs are substances that affect the brain to change mood, perception, and thinking. Marijuana is a classic example because its active component, THC, interacts with cannabinoid receptors in the brain, leading to altered sensory perception and mood. This term is the broad umbrella for drugs that modify mental processes, not just one specific effect like increased energy or pain relief. The other options don’t fit as well: stimulants describe drugs that mainly boost alertness and activity; opioids are a specific class focused on pain relief and mood effects; consolidation theory isn’t a drug category at all.
