Marijuana and LSD are categorized as which type of drug?

  1. Stimulants

  2. Depressants

  3. Hallucinogens

  4. Opioids

The correct answer is: Hallucinogens

Marijuana and LSD are categorized as hallucinogens because they primarily alter perception, thought processes, and mood. Hallucinogens are substances that can cause significant changes in sensory perceptions, leading to experiences that may not correspond with reality. LSD, known for its potent psychoactive effects, directly interacts with serotonin receptors in the brain to create vivid visual and auditory hallucinations. Marijuana, while it also has depressant and stimulant effects depending on the strain and dosage, contains compounds like THC that can induce altered states of consciousness and perceptual changes typical of hallucinogenic experiences. This categorization underlines the unique psychological effects these substances have compared to other drug types, such as stimulants or opioids, which affect the nervous system in different ways.
