The Human Fascination with Altered States
For thousands of years, humans have explored altered states of consciousness, whether through meditation, fasting, or the use of psychoactive plants. Psychedelics, in particular, have played a central role in spiritual rituals, healing ceremonies, and now increasingly, clinical research.
In this article, we’ll take an objective look at the different classes of psychedelics, how they are understood scientifically, and what current research reveals about their potential effects and risks.
What Are Psychedelics?
Psychedelics sometimes referred to as hallucinogens, are substances that can alter perception, thought, and mood. Rather than simply stimulating or sedating the brain, they tend to disrupt normal processing and perception, often in profound ways.
They are generally grouped into three categories:
- Classic Psychedelics
- Dissociatives
- Deliriants
Each group interacts with different neural pathways and has its own unique profile of effects and risks.
1. Classic Psychedelics
These substances are the most widely studied and historically documented. They primarily affect serotonin receptors (especially 5-HT2A), which play a role in mood, cognition, and perception.
LSD (Lysergic Acid Diethylamide)
- Origin: First synthesized from a fungus found on rye
- Known for: Visual distortions, time perception changes, and vivid mental imagery
- Duration: Around 8–12 hours
- Research: Studied for its potential to assist with anxiety and depression, particularly in end-of-life care
Psilocybin (from certain mushrooms)
- Found in: Over 180 species of mushrooms around the world
- Reported experiences: Enhanced emotional awareness, dream-like visuals
- Duration: 4–6 hours
- Clinical interest: Active studies exploring its use for major depressive disorder and addiction
DMT (Dimethyltryptamine)
- Occurs naturally in both plants and small amounts in the human body
- Reported effects: Intense visual states, loss of ego or identity, symbolic visions
- Duration: A few minutes when inhaled, longer in traditional brews like ayahuasca
- Cultural relevance: Used in South American ceremonial contexts
Mescaline
- Source: Found in certain cacti such as peyote and San Pedro
- Subjective reports: Color-rich visuals, emotional openness, philosophical thought
- Duration: 8–12 hours
- Historical use: Deep roots in Native American spiritual practices
2. Dissociatives
Dissociatives work differently. They interfere with glutamate signaling (via NMDA receptors), often resulting in a sense of detachment from the body or environment.
Ketamine
- Developed as an anesthetic in the 1960s
- Subjective effects: Disconnection from surroundings, altered sensory input
- Duration: 45–90 minutes
- Current use: Approved in some countries for treatment-resistant depression under strict medical supervision
PCP (Phencyclidine)
- Originally created as a surgical anesthetic
- Reported effects: Dissociation, hallucinations, impaired coordination
- Risks: Can lead to psychological disturbances and has a high potential for misuse
DXM (Dextromethorphan)
- Found in: Many over-the-counter cough medications
- At high doses: May cause disorientation, hallucinations, and dissociative states
- Warnings: High-dose misuse can lead to serious health issues
3. Deliriants
Deliriants are generally considered the least predictable and most physically risky group. Their effects often include hallucinations that feel real but are disconnected from reality, along with confusion and memory loss.
Datura & Belladonna
- Source: Toxic plants used historically in various folk traditions
- Typical reports: Intense disorientation, visual and auditory hallucinations
- Risks: High toxicity, potential for dangerous behavior, and little modern clinical interest
Risks vs. Emerging Benefits
Research-Driven Potential:
- Studies at institutions like Johns Hopkins and Imperial College London suggest some psychedelics may assist in treating:
- Depression
- PTSD
- Addiction
- End-of-life anxiety
- These treatments always occur under strict clinical supervision, using highly controlled dosages and screening protocols.
Known Risks:
- Bad psychological reactions (aka “bad trips”)
- Potential to trigger latent mental health conditions
- Hallucinogen Persisting Perception Disorder (HPPD)
- Legal consequences, depending on region
Use outside of medical or cultural contexts carries clear health and legal risks, especially without professional guidance.
Legal & Cultural Contexts
The legal status of psychedelics varies dramatically around the world.
- Psilocybin is decriminalized in some cities like Denver and Oakland but remains federally restricted.
- LSD and DMT are generally classified as controlled substances in most jurisdictions.
- Indigenous use of ayahuasca and peyote is protected in certain regions due to religious and cultural rights.
Regulation is evolving as research continues, but legality remains a key concern.
Final Thoughts
Psychedelics sit at a fascinating intersection of science, culture, spirituality, and medicine. They offer deep insight into the workings of the mind and human consciousness, but their complexity demands respect, caution, and further study.
As research progresses, society is being challenged to look at these substances not through fear or hype, but through the lens of evidence, ethics, and cultural understanding.
