Hallucinogens 101: Effects, Types, and Legal Status

What Are Hallucinogens?

Hallucinogens are a class of psychoactive substances that cause profound changes in perception, mood, and cognitive processes. They affect the way the brain processes sensory input, often leading to visual or auditory hallucinations, altered sense of time, and deep introspective experiences.

Common hallucinogens include:

  • Psilocybin mushrooms (commonly called magic mushrooms)
  • LSD (Lysergic acid diethylamide)
  • PCP (Phencyclidine)
  • DMT (Dimethyltryptamine)
  • Mescaline

Hallucinogens can be categorized into classic psychedelics, dissociatives, and deliriants based on their chemical structures and effects. For more details on psychedelic classification, see our article on Psychedelic vs. Hallucinogen: What’s the Difference?

Common Types of Hallucinogens

Mushrooms (Psilocybin)

Psilocybin-containing mushrooms are among the most popular natural hallucinogens. These fungi contain compounds that convert into psilocin in the body, producing vivid visual hallucinations and altered states of consciousness.

LSD

LSD is a powerful synthetic hallucinogen known for its intense visual effects and profound shifts in perception. It is often consumed via tabs or liquid form.

PCP

Phencyclidine (PCP), originally developed as an anesthetic, is a dissociative drug that can cause hallucinations and feelings of detachment from reality.

  • Mescaline: Found in peyote and San Pedro cacti, mescaline produces colorful hallucinations. View details on our Mescaline page.

Effects on the Mind and Body

Hallucinogens primarily alter brain activity by interacting with serotonin receptors, especially the 5-HT2A receptor, which influences mood, cognition, and perception.

Common effects include:

  • Visual distortions and hallucinations
  • Altered perception of time and space
  • Emotional shifts ranging from euphoria to anxiety
  • Changes in thought patterns and self-awareness

Physically, some hallucinogens can cause increased heart rate, nausea, dizziness, or muscle weakness depending on the substance and dosage.
