Mechanism of action
Mescaline (3,4,5-trimethoxyphenethylamine) is a naturally occurring psychoactive alkaloid from the phenethylamine group, present in two species of cacti: the North American Lophophora Williamsii, known as Peyote, and the South American Echinopsis Pachanoi, also known as San Pedro or Huachuma. Mescaline is a substance with long-lasting effects and low potency. The oral dose of mescaline is usually 200-400 mg, which is three times the amount compared to an equivalent dose of LSD. Once taken, mescaline has a longer duration of action compared to other classic psychedelics (which is about 6 hours). The total duration of action of mescaline is 8 to 12 hours. The substance is metabolized in the liver, and is mostly excreted in the urine within 24 hours.
Mescaline exhibits complex neurochemical interactions that are central to its effects. Acting as an agonist of serotonin receptors, particularly 5-HT2A, it affects various areas of the brain, leading to phenomena that can be both extremely inspiring and deeply transformative.
Interaction with serotonin receptors
Mescaline exerts a powerful effect on the nervous system by interacting with serotonin receptors, particularly the 5-HT2A receptor. Once mescaline binds to this receptor, it activates neural pathways that are key to regulating mood, perception and emotional experiences.
5-HT2A receptors are particularly important in the context of neurobiological processes, as they play a role in modulating the secretion of neurotransmitters such as dopamine, norepinephrine, and GABA. The increased communication between neurons resulting from this modulation can lead to changes in the perception of reality and effects on emotional states. In practice, this means that mescaline users can experience intensification of the senses, altered perception of time and space, and deep emotional and spiritual reflections.
Neuroplasticity
Increased serotonin receptor activity is central to neuroplasticity processes. Neuroplasticity refers to the brain’s ability to adapt to new information, experiences and environmental conditions by reorganizing synapses – connections between neurons. This phenomenon is fundamental to learning and memory, as it enables the brain to accumulate new information and integrate it into existing neuronal networks.
In the context of substances such as mescaline, which is a hallucinogen that acts on serotonin receptors, potential changes in thinking and perception can result from intense stimulation of these receptors. When mescaline activates serotonin receptors, an increase in synaptic plasticity can be observed, leading to new neuronal connections and changes in existing networks. Such phenomena can promote intensification of sensory experiences, changes in thinking, and a broadened perspective of reality perception.
With the ability to process information more efficiently and form new connections, some mescaline users may experience an intensification of creativity, a change in the way they perceive problems or a sense of deeper connection with their surroundings. This can lead to personal or spiritual discoveries, as well as influence art, music or other creative activities.
However, while neuroplasticity has many positive aspects, excessive or inappropriate stimulation of serotonin receptors can also carry the risk of negative effects, including mood disorders or problems with perception of reality. It is therefore important to approach this substance with caution and awareness of its potential effects, both positive and negative.
Activation of key brain areas
Mescaline has the ability to affect various areas of the brain, including the prefrontal cortex and limbic system. The prefrontal cortex plays a key role in thought processes, and its activity correlates with the ability to think critically, assess situations and make decisions. Increased activity of this part of the brain during mescaline experiments may support the development of new thinking, creativity and the ability to analyze problems from different perspectives. One effect of mescaline may be an increased ability to see connections between different elements of reality, leading to more accurate or creative decisions.
On the other hand, activation of the limbic system, which is responsible for processing emotions, can potentiate the intensity of emotions felt. Mescaline often evokes deeply personal experiences, as well as states of euphoria, anxiety or reflection. Intensification of emotions promotes introspection, which can lead to understanding one’s own thoughts, feelings and behavior. In a therapeutic context, such deep experiences can be beneficial, allowing people to confront difficult aspects of their lives, which can be a step toward mental healing.
In addition, the combination of these two effects – improved critical thinking processes and increased emotional activity – can lead to a holistic understanding of oneself and the surrounding world. It is possible to discover new perspectives on one’s own life, relationships with other people and life’s aspirations, which can result in changes in thinking and daily decision-making. Such reflections can be crucial for personal growth and self-discovery, pointing to potential positive aspects of mescaline use in the context of self-improvement or spiritual development.
History of mescaline use
Mescaline played a key role in the traditions of the indigenous peoples of North and South America, being an integral part of their religious rituals and spiritual practices. They believed that mescaline, opened the door to alternate states of consciousness, allowing for deeper contact with ancestral spirits and the divine. Many indigenous cultures viewed mescaline as a sacred means for spiritual transformation, healing and understanding the meaning of life. The rituals in which mescaline was used were often complex and full of symbolism. They included prayers, music, dancing and various forms of artistic expression, and were designed to achieve a trance-like state in which participants could experience visions and deep introspection. In such a state of mind, they believed they could discover the mysteries of the universe, gain insights into their lives and heal both themselves and others. Such ceremonies played a fundamental role in strengthening social bonds and in passing important teachings and traditions from generation to generation.
We discuss this topic in more detail in this article
In the 20th century, interest in mescaline increased, especially during one of the most interesting eras in cultural history – the period of the development of the hippie and psychedelic movements. Mescaline found its place in artistic and intellectual circles, becoming the subject of much research and exploration. Thanks to thinkers such as Aldous Huxley, who detailed his experiences in his book “The Doors of Perception” (1954), mescaline gained new, more Western connotations. Huxley portrayed it as a tool for exploring other dimensions of perception and a way to see and understand deeper truths about human experience.
Over time, mescaline became a symbol of spiritual exploration that inspired artists, writers, as well as scientists to further explore the possibilities inherent in achieving states of altered consciousness. The hippie movement, inspired by Huxley’s ideas, sought ways to break with conventional lifestyles and explore new ways of being, often through art, music and experimentation with psychoactive substances. For many, it was “The Doors of Perception” that served as a kind of guide to new, previously unknown dimensions of reality. Jim Morrison (who, incidentally, named his band “The Doors” under the influence of this reading), creating his music and image, became the voice of a generation that wanted to awaken from materialistic existence. Huxley’s book also contains reflections on art, religion and the nature of the human soul, which only intensified its impact on the work of artists of the time. The Doors’ music became a symbolic bridge between the world of the senses and spirituality. Their songs often dealt with themes of transcendence, rebellion and the exploration of human nature. Morrison, as the band’s charismatic leader, took on the role of poet and mystic, guiding listeners toward the discovery of their own perception and authenticity.
As psychoactive substances grew in popularity, concerns began to emerge about their impact on mental health and the social order. The government and medical institutions began to recognize that mass experimentation with psychedelics could lead to unpredictable consequences, including problems with addiction and mental disorders. In the United States in the 1970s, prompted by growing concerns and increasing incidents of substance abuse, the government introduced a series of regulations aimed at restricting access to psychoactive substances. In 1970, the Controlled Substances Act was passed, which classified mescaline as a banned substance in what was known as Category I, meaning that it was considered to have a high potential for abuse and no recognized medical value. The decision was also motivated by a desire to combat cultural and social phenomena associated with the hippie movement and the ideology of freedom, which were often seen as a threat to traditional values. Thus, mescaline, along with other psychedelics, became a banned substance, and its use was restricted to a small number of legitimate contexts (such as in the traditional practices of some indigenous cultures).
Today, mescaline is still the subject of scientific research, and some scientists and therapists are trying to study its potential therapeutic properties, but its legal status in many countries remains restrictive.
Mescaline in a therapeutic context
Modern research on mescaline and its effects on the psyche and mental health has opened new perspectives in psychedelic therapy, highlighting its potential for treating depression, anxiety or PTSD. In addition, a resurgent trend toward reconstruction and respect for the traditional spiritual practices of the Native American population has contributed to a new focus on mescaline as a tool for both personal growth and cultural rebirth.
A 2021 study published in the Journal of Psychopharmacology found that the exploratory experience of mescaline use can lead to long-term positive changes in perceptions of self and surroundings. Study participants experienced improvements in emotional well-being and greater openness to new experiences. This enabled a better understanding of the self, which can be crucial in the context of therapy for people suffering from various types of mental disorders. Such findings are becoming increasingly attractive to therapists seeking alternative treatments that can support traditional therapies.
Animal studies have shown that mescaline can support the process of neurogenesis, or the production of new nerve cells. This is particularly important in the context of depression, in the course of which this process is often disrupted. Supporting neurogenesis can therefore positively influence brain regeneration and improve brain function, which can help alleviate depressive symptoms.
In addition, mescaline may affect other neurotransmitters, including serotonin, which may be related to mood enhancement and anxiety reduction. Consequently, much research is focused on understanding how mescaline and other psychedelics can be used as part of more comprehensive therapeutic approaches that combine psychological and neurobiological aspects. It is worth noting that research on mescaline and other psychedelics is not limited to therapeutic aspects. They also reveal the potential of these substances in the context of personal development, creativity and improved quality of life. More and more people are recognizing that mental health encompasses not only the treatment of illness, but also the pursuit of self-realization and a full life.
As research on psychedelics and their role in psychotherapy continues to grow, mescaline may gain prominence as an innovative tool that, when combined with conventional treatments, can provide relief for those struggling with mental health difficulties. However, it will be crucial to further study its long-term effects and determine under what conditions such substances can be safely and effectively used.
While research on mescaline is promising, the potential risks associated with its use cannot be overlooked. As with other psychoactive substances, there is a risk of abuse and psychotic episodes, especially for those with a history of psychiatric disorders. The effects of mescaline can also lead to unpredictable effects, such as anxiety or restlessness during the experience. Further investigation of both therapeutic effects and potential risks is crucial to ensure its safe and effective medical use.
