Welcome to PsychoactiveWiki
Your collaborative, community-driven reference on psychoactive substances — their effects, risks, chemistry, history, cultural roles, and safe practices. This wiki aims to combine accessible explanations with evidence-informed content, offering a balanced and responsible perspective on altered states of consciousness. Whether you are a researcher, clinician, harm-reduction advocate, or curious learner, PsychoactiveWiki provides a structured and growing foundation for understanding substances and the ways they interact with mind, body, and culture.
⚠️ For Educational and Harm-Reduction Purposes Only
PsychoactiveWiki does not encourage, promote, or endorse the use of psychoactive substances under any circumstances. All content on this site is intended strictly for:
- educational use — understanding mechanisms, effects, and contexts
- harm reduction — minimizing risks where use occurs
- scientific, cultural, and historical documentation — preserving knowledge with accuracy and neutrality
Psychoactive substances carry genuine risks — physical, psychological, legal, and social. Effects vary greatly between individuals, contexts, and dosages. Individual physiology, mental health history, interactions, and environmental conditions all influence how substances act.
Always follow local laws. Always prioritize safety. Consult a licensed medical or mental-health professional when needed. This wiki does not give medical advice, cannot diagnose conditions, and is not a substitute for professional guidance.
If you are experiencing a medical or psychological emergency, contact local emergency services immediately.
Featured Article
Featured articles highlight a significant, well-documented, or historically important psychoactive substance. These entries showcase the level of depth, quality, and clarity we aim to maintain across the project. Featured articles may rotate to highlight new contributions, major updates, or noteworthy topics.

Psilocybin
Psilocybin is a naturally occurring tryptamine psychedelic found in over 200 species of mushrooms. It is known for its visual phenomena, emotional amplification, introspection, and potential therapeutic applications. Used in spiritual, indigenous, and modern clinical contexts for centuries, psilocybin occupies an important role in the study of consciousness, neuroplasticity, and mental health interventions. Recent scientific interest has increased dramatically due to research into treatment-resistant depression, end-of-life anxiety, and addiction.
Categories
Below are the major substance groups used on PsychoactiveWiki. Each category organizes pages by pharmacology, effects, and experiential characteristics, allowing readers to explore substances by shared mechanisms or subjective profiles.
- — Serotonergic and tryptamine-based mind-altering substances associated with perception change, introspection, and altered cognition.
- — NMDA antagonists producing detachment, dreamlike states, analgesia, and altered embodiment.
- — Substances that increase alertness, energy, attention, and sympathetic nervous activity.
- — Sedatives and CNS depressants affecting inhibition, coordination, and cognition, often with calming or numbing effects.
- — Compounds that enhance empathy, connection, openness, and emotional warmth.
- — Novel or understudied substances with limited safety data and rapidly evolving legal status.
- — Botanicals, fungi, ethnobotanicals, and traditional psychoactives used historically across cultures.
- — Laboratory-developed compounds across many pharmacological classes, from therapeutics to analogues.
Harm Reduction
Harm reduction is the central mission of this wiki. Every aspect of this project is structured around minimizing risk, increasing understanding, and promoting informed decision-making. The goal is to reduce harm—not to encourage use. Providing accurate information is one of the most effective ways to prevent injury, panic, and avoidable medical emergencies.
Users are encouraged to explore foundational harm-reduction topics:
- General harm reduction principles — A broad overview of safe practices.
- Set, Setting & Psychological Preparedness — How mindset and environment shape outcomes.
- Safe dosage practices — Understanding thresholds, variances, and substance-specific considerations.
- Dangerous combinations & interactions — Avoiding hazardous or lethal interactions.
- Recognizing and responding to medical emergencies — What to do when things go wrong.
These pages synthesize information from scientific literature, community reports, harm-reduction collectives, and public health resources.
