What Is a San Pedro Cactus Experience Like? What About Peyote Experiences?

San Pedro cactus and Peyote – two plant medicines with the power to take you on a magical, spiritual journey. To commune with the infinite.

Both contain mescaline, an alkaloid that interacts with receptors in the brain, causing hallucinations and shifts in thought patterns. Thanks to this molecule, psychedelic cacti can be used for spiritual exploration, improving mental health, fighting addiction, and more.

But what is a San Pedro cactus experience like? What about Peyote? What is a Peyote experience like? That’s what we’ll explore in this article.

In addition, we’ll go over the key differences between psychedelic cacti and Ayahuasca, psilocybin, and 5-MeO-DMT experiences.

What Is a San Pedro Cactus Experience Like?

A San Pedro cactus experience can be visually stimulating — visual distortions, vibrant colors, and geometric patterns are common.

However, most people describe it as gentle, introspective, and emotionally profound.2

Enhanced sensory perception, feeling connected to nature or your surroundings, and emotional clarity are also frequently mentioned effects.

How to Consume San Pedro Cactus (Mescaline)

The most effective, traditional, and common way is to turn it into a brew by slicing it into small pieces, boiling it, and simmering it for several hours to extract the San Pedro cactus mescaline.

The resulting liquid is then strained and drank. Sometimes sweeteners or flavorings are added to improve the bitter taste of the brew.

Other ways to consume hallucinogenic cactus include:

  • Chewing it fresh or dried
  • Soaking it fresh or dried to make an intoxicating liquid
  • Grinding it into a powder and swallowing or smoking it (the latter is not recommended)

San Pedro Cactus Psychedelic Effects

Here’s how Humphry Osmond, the psychiatrist who coined the term ‘psychedelic’ in 1953, described the effects of mescaline, the hallucinogenic in San Pedro cactus:

  • Rainbow sheen of visual trails
  • Scintillating patterns exploding across closed eyelids
  • Auditory hallucinations
  • Time distortion
  • Lazy euphoria
  • Fullness in the head
  • Ineffable cosmic insights
  • Sense of double consciousness
  • Inherent presence of the sacred

As for side effects, he mentioned dizziness, nausea, hyperventilation, physical prostration, and increased heart rate.

Know that compared to psilocybin or LSD, the effects of mescaline are notoriously unpredictable and individual-dependent.

San Pedro Cactus’ Hallucinogenic Properties

Here are the most commonly reported San Pedro cactus hallucinogenic properties:

  • Mild to major visual distortions (e.g., objects shifting form or size)
  • More vivid, enhanced colors
  • Moving patterns and intricate geometric shapes
  • Distorted or heightened sounds

Compared to some other psychedelics, mescaline hallucinations are often more organic and flowing rather than intense and overwhelming.

Heinrich Klüver, the German psychologist who authored the 1928 book “Mescal,” reported that there are some repeating motifs such as latticework, filigree, tunnels, spirals, cobwebs, and polyopia.

Also, some people experience synesthesia — seeing sounds or hearing colors, for example.

What Is a Peyote Experience Like?

Here’s how Anna Heimkreiter, a German artist who took Peyote in the Mexican desert, described her experience:

My mind feels sharp, very aware. Peyote does not cloud your mind — it brings you closer to consciousness. I perceive everything around me very intensely. I am one with my surroundings. […] Even the cold is more intense. […] I am alive with all my senses.”

How Is a Peyote Experience Different From San Pedro Cactus?

Since both Peyote and San Pedro cactus contain mescaline, the experiences are pretty similar.

The only difference is that Peyote has a higher mescaline concentration, meaning you’ll need a smaller dose and may have a more intense experience.

Up next, we’ll go over the key differences between hallucinogenic cacti and Ayahuasca, psilocybin, and 5-MeO-DMT experiences.
