What Are Shrooms? A Complete Beginner’s Guide to Psychedelic Mushrooms

Originally published on April 10, 2025

Psychedelic mushrooms—often called “shrooms” or “magic mushrooms”—have fascinated humans for thousands of years. Known for their mind-altering effects and deep psychological experiences, these fungi contain powerful natural compounds that can change perception, mood, and consciousness.

Today, psychedelic mushrooms are gaining renewed attention. Scientists are researching their potential for mental health treatment, and many people are curious about how they work, what they feel like, and whether they are safe.

If you’re new to the topic, this beginner’s guide explains everything you need to know about shrooms, including how they work, what effects to expect, how long they last, and important safety considerations.

What Are Shrooms?

Shrooms are a group of mushrooms that contain psilocybin, a naturally occurring psychedelic compound. When consumed, psilocybin converts into psilocin, which interacts with serotonin receptors in the brain and causes psychedelic effects.

These effects may include:

• Visual distortions or patterns
  
• Enhanced emotions
  
• Altered perception of time
  
• Increased introspection
  
• Spiritual or philosophical insights
  

Because of these effects, psilocybin mushrooms are classified as psychedelics, a group of substances that alter perception and consciousness.

More than 180 species of mushrooms contain psilocybin, but only a few are commonly used for psychedelic experiences.

A Brief History of Psychedelic Mushrooms

Psychedelic mushrooms have been used by humans for thousands of years.

Archaeological and historical evidence suggests that indigenous cultures in Central and South America used psilocybin mushrooms in spiritual ceremonies and healing rituals.

In Mesoamerican cultures, these mushrooms were often referred to as “teonanácatl,” meaning “flesh of the gods.”

Spanish colonists documented these ceremonial uses in the 16th century, though many traditions were later suppressed.

Interest in psychedelic mushrooms resurfaced in the 1950s and 1960s, when researchers began studying their effects on consciousness and mental health. Today, scientific research is once again exploring psilocybin’s therapeutic potential.

Types of Psychedelic Mushrooms

There are many different species of psilocybin mushrooms, but a few are especially well known.

Psilocybe cubensis

This is the most common psychedelic mushroom species.

It is widely cultivated and relatively easy to grow. Many beginner users encounter this species first.

Common varieties include:

• Golden Teacher
  
• B+
  
• Penis Envy
  
• Mazatapec
  

Each strain may vary slightly in potency and appearance.

Psilocybe semilanceata (Liberty Caps)

Liberty Caps are among the most potent naturally occurring psilocybin mushrooms.

They grow in grassy fields in parts of Europe and North America.

Psilocybe azurescens

This species is considered one of the strongest psilocybin mushrooms known.

It is primarily found in the Pacific Northwest of the United States.

How Do Shrooms Work in the Brain?

The psychedelic effects of magic mushrooms come from psilocybin.

After consumption, psilocybin converts into psilocin in the body.

Psilocin affects the brain by interacting with serotonin receptors, particularly the 5-HT2A receptor, which plays a role in mood, cognition, and perception.

When these receptors are activated, the brain may:

• Increase communication between different regions
  
• Reduce activity in the brain’s default mode network
  
• Alter sensory processing
  

This combination of changes can create the distinctive psychedelic experience associated with shrooms.

Researchers believe these effects may help explain why psilocybin shows promise in treating certain mental health conditions.

What Does a Shroom Trip Feel Like?

The effects of shrooms vary from person to person, but many experiences share similar characteristics.

Visual changes

Users may notice:

• Colors appearing brighter
  
• Geometric patterns
  
• Moving or breathing surfaces
  
• Enhanced appreciation of art or nature
  

Emotional changes

Many people report:

• Increased empathy
  
• Emotional release
  
• Feelings of connection
  
• Deep introspection
  

However, emotions can also become intense or overwhelming for some individuals.

Cognitive changes

Shrooms can influence thinking patterns.

Some people describe:

• New perspectives on personal issues
  
• Philosophical insights
  
• Creative ideas
  

How Long Do Shrooms Last?

A typical psychedelic mushroom experience lasts 4–6 hours, though this can vary depending on the dose and the individual.

Here’s a general timeline:

1. Onset (20–60 minutes)

After consumption, effects begin gradually.

Early sensations may include:

• Lightheadedness
  
• Mood changes
  
• Mild visual distortions
  

2. Peak (2–4 hours)

This is the most intense phase.

Users may experience:

• Strong visual effects
  
• Altered perception
  
• Emotional intensity
  

3. Comedown (1–2 hours)

The effects gradually fade, often leaving users feeling reflective or calm.

Beginner Dosage Guide

The intensity of a psychedelic experience depends largely on dosage.

Below is a general guideline for dried mushrooms.

Experience Level	Dose
Microdose	0.1–0.3 g
Light	0.5–1 g
Moderate	1–2 g
Strong	3–5 g

Beginners are typically advised to start with low doses to understand how their body responds.

Microdosing Psychedelic Mushrooms

Microdosing involves taking very small amounts of psilocybin that do not produce full psychedelic effects.

Typical microdoses range from 0.1 to 0.3 grams of dried mushrooms.

Some people believe microdosing may help with:

• Creativity
  
• Focus
  
• Mood improvement
  

However, research on microdosing is still ongoing, and results vary.

Potential Benefits of Psilocybin

Scientific research into psilocybin has expanded rapidly in recent years.

Studies suggest it may have potential benefits for mental health when used in controlled settings.

Researchers are investigating psilocybin for conditions such as:

Depression

Clinical trials have shown promising results for treatment-resistant depression.

Anxiety

Psilocybin therapy may help reduce anxiety in patients with serious illnesses.

PTSD

Some researchers are exploring psychedelics as tools for trauma processing.

Addiction

Studies suggest psilocybin may help people overcome addictions such as smoking or alcohol dependence.

It is important to note that these treatments occur in controlled medical environments, not recreational settings.

Risks and Side Effects

Although many people report positive experiences, shrooms can also carry risks.

Possible side effects include:

• Anxiety or panic
  
• Confusion
  
• Nausea
  
• Increased heart rate
  
• Paranoia
  

A difficult psychedelic experience is sometimes called a “bad trip.”

This may involve intense fear or emotional discomfort.

Certain individuals should avoid psychedelics entirely, including those with a history of:

• Psychotic disorders
  
• Schizophrenia
  
• Severe mental illness
  

The Importance of Set and Setting

In psychedelic culture, the phrase “set and setting” is extremely important.

Set

Your mindset before taking shrooms.

This includes your emotions, expectations, and mental state.

Setting

The environment where the experience occurs.

Safe, comfortable environments tend to produce more positive experiences.

Many experienced users recommend:

• Being with trusted friends
  
• Avoiding stressful environments
  
• Having a calm, safe space
  

Are Magic Mushrooms Legal?

The legal status of psilocybin mushrooms varies widely around the world.

In many countries, psilocybin is classified as a controlled substance.

However, laws are changing in some areas.

Examples include:

• Oregon (USA) allowing regulated psilocybin therapy
  
• Some cities decriminalizing personal possession
  
• Canada permitting limited medical exemptions
  

Because laws differ by region, it is important to check local regulations.
