Every time I want to talk about something, I think – hey, man, the Internet is already full of information about everything and definitely about such topics as “how LSD works”. Why shake the air and waste someone else’s time?

Then I try to find articles and publications that seem to me quite simple and exhaustive. And you know that, despite decades, there is still a hell of a lot of clear, reliable, and simply written information on many issues related to the work of our brain and its interaction with exogenous substances on the Web. And in general, this may concern many areas.

Therefore, do not be surprised when you see here banal headlines on topics that have long been clear to everyone. It seems to me that you can still make your contribution. And yes, it helps the SEO things too.

What is LSD?

What is LSD?

LSD is a powerful psychoactive substance that was first synthesized in 1938 by the Swiss chemist Albert Hofmann. LSD belongs to a group of substances known as hallucinogens or psychedelics. Its effects on the human body are complex and still not fully understood, but the primary mechanisms of action are believed to revolve around its interactions with the brain’s serotonin system.

LSD is derived from ergot, a fungus that grows on rye and other grains. Its chemical structure is complex and it’s usually synthesized in a laboratory setting. The full chemical name is D-lysergic acid diethylamide.

In its pure form, LSD is a white, odorless powder. However, it’s typically diluted and distributed on small pieces of paper known as “blotter paper,” which are often decorated with colorful designs. LSD can also be found in liquid form, in thin squares of gelatin, or on sugar cubes.

Despite its reputation as a party drug, LSD is non-addictive and is not known to cause brain damage. However, it can have potent psychological effects and lead to dangerous behavior if used improperly. It can also cause negative psychological reactions like anxiety, paranoia, and psychosis, particularly in individuals predisposed to mental health disorders.

In most countries, LSD is classified as an illegal substance, though recent years have seen a resurgence of scientific interest in its potential therapeutic uses, particularly in the treatment of mental health disorders such as depression and PTSD.

Mechanism of Action of LSD

Mechanism of Action of LSD

LSD interacts with various neurotransmitter systems in the brain, but it’s primarily known for its ability to bind to and activate the serotonin 2A receptor, leading to its characteristic psychedelic effects. These can include visual and auditory hallucinations, altered perception of time and space, intensified feelings and sensory experiences, and introspective experiences that some users describe as spiritual or enlightening.

Serotonin is a neurotransmitter, a chemical messenger in the brain, playing an essential role in many functions, such as mood regulation, cognition, and perception. There are several different subtypes of serotonin receptors in the brain, each with unique roles. LSD has a high affinity for the serotonin 2A receptor (5-HT2A).

When LSD enters the bloodstream, it crosses the blood-brain barrier and binds to the 5-HT2A receptors, primarily located in the brain’s prefrontal cortex. The activation of these receptors leads to a cascade of neurochemical events.

By stimulating these receptors, LSD significantly alters sensory perception, cognitive processes, and mood. The distortions of sensory perception can lead to hallucinations, changes in time perception, synesthesia (crossing of sensory modalities, such as “hearing” colors), and intensified emotional experiences.

In addition to direct receptor interaction, LSD also impacts the brain’s Default Mode Network (DMN), a network of interacting brain regions that comes active when the mind is in a wakeful rest state, not focusing on the outside world. The DMN is associated with self-referential thoughts and introspection.

LSD decreases the integrity of the DMN, leading to a state often referred to as “ego dissolution” or a loss of the sense of self. This experience often results in feelings of increased connectedness or unity with the world around the user, and can sometimes lead to profound changes in perspective and self-awareness.

Effects of LSD

Effects of LSD

The effects of LSD can be highly variable. They can be broadly categorized into physical, perceptual, cognitive, and emotional effects, and can vary greatly depending on the individual, the dose, and the context in which the drug is used.

Physical Effects

  1. Pupil dilation: This can lead to heightened sensitivity to light.
  2. Increased heart rate and blood pressure: LSD can stimulate the sympathetic nervous system, which controls the body’s “fight or flight” response.
  3. Decreased appetite, dry mouth, and sweating: These effects are also linked to stimulation of the sympathetic nervous system.
  4. Insomnia: LSD can cause hyperactivity and disrupt sleep patterns.
  5. Tremors: Some people experience tremors or shaking.

Perceptual Effects

  1. Visual Hallucinations: Users often see geometric patterns, bright or intensified colors, and alterations in the shape or meaning of objects.
  2. Synesthesia: This is a cross-over of senses, such as “seeing” sounds or “hearing” colors.
  3. Altered sense of time: Some users experience time dilation, where time appears to slow down, or feel that time is looping or warping.

Cognitive Effects

  1. Thought Connectivity: Users often experience rapidly connecting thoughts or ideas.
  2. Ego Dissolution: LSD can lead to a loss of the sense of self, sometimes leading to feelings of unity or interconnectedness with the world around them.
  3. Enhanced Creativity: Some users report increased creativity and introspective thought.

Emotional Effects

  1. Euphoria: Many users experience a heightened sense of joy and wellbeing.
  2. Anxiety or Paranoia: LSD can also lead to negative emotional states, particularly if the user is in a stressful or unfamiliar environment.
  3. Mood Swings: Rapid shifts between different emotional states can occur.


  1. “Afterglow”: Users often report a period of enhanced mood and increased mental clarity in the days following an LSD experience.
  2. Fatigue: The physical and mental exertion of an LSD experience can leave users feeling tired or drained.
  3. Flashbacks: Some users experience brief, spontaneous recurrences of the perceptual effects of LSD, even long after the drug has worn off. These are usually harmless but can be distressing.

Remember, LSD’s effects can be unpredictable and can potentially lead to dangerous situations or psychological distress. While many people have positive experiences with LSD, others have negative or even traumatic experiences. Always prioritize safety, legality, and mental health when considering any substance use.

What to Do If Someone Experiences Problems

If someone experiences distress or confusion while on LSD, it’s important to reassure them that they’re in a safe environment and that the effects are temporary. If symptoms persist or if the person’s behavior becomes erratic or dangerous, seek immediate medical attention.

To avoid potential problems, it’s also important to use substances like LSD responsibly and in a safe and supportive environment. It’s not recommended for individuals with a personal or family history of psychotic disorders, as it can trigger or worsen symptoms.

For more information, see my articles:

Tolerance and Withdrawal

With repeated use, tolerance to LSD builds up quickly. This means that users need to take higher doses to achieve the same effects. Usually, the tolerance of substances gradually accumulates and decreases relatively quickly. But psychedelics, and LSD in particular, exhibit tolerantly similar properties literally after the first application. It is impossible to use LSD adequately after a day or even several days. In such conditions, any person will encounter weakened main effects and enhanced side reactions that squeeze the last juices from the serotonin system of the brain. The average period of recovery and reduction of tolerance of psychedelics and LSD is considered to be a period of 2 weeks.

Long-Term Effects on the Brain

Long-Term Effects on the Brain

The long-term effects of LSD on the brain are not fully understood, mainly because its illegal status in many countries has hindered scientific research. However, some potential long-term effects have been suggested based on limited studies and anecdotal reports:

Hallucinogen Persisting Perception Disorder (HPPD): Some people report persistent perceptual changes after using LSD. These can include “flashbacks,” or the re-experiencing of LSD-like effects after the drug has worn off. This condition, called HPPD, is relatively rare and often resolves over time, but it can be distressing.

Persistent Psychosis: Very rarely, people may experience persistent psychosis after taking LSD, which can include visual disturbances, disorganized thinking, paranoia, and mood changes. This is more likely in individuals with a personal or family history of psychotic disorders.

Changes in Personality or Attitudes: Some people report lasting changes in their personality, attitudes, or beliefs after using LSD. These are often described as positive changes, like increased openness, creativity, or spiritual awareness, but they can also be distressing if they lead to conflict with previous beliefs or social norms.

Potential Therapeutic Effects: There is growing interest in the potential therapeutic uses of LSD for conditions like depression, anxiety, and post-traumatic stress disorder (PTSD). Some research suggests that LSD, used under controlled, therapeutic conditions, can produce lasting reductions in symptoms. However, this is an emerging field and more research is needed to fully understand these potential benefits and the risks involved.

In general, LSD is considered non-addictive and does not cause brain damage. However, because of its powerful psychological effects, it can lead to dangerous behavior if used in an unsafe setting or without proper support. LSD use should always be approached with caution, especially by individuals with a history of mental health problems.

LSD as a Therapeutic Option

The number of studies on LSD on PubMed from 1950 to the present day

The history of LSD as a potential therapeutic substance dates back to the mid-20th century, not long after it was first synthesized.

LSD in the Mid-20th Century

From the 1950s to the early 1970s, researchers conducted dozens of studies on LSD, many of which focused on its potential therapeutic applications. During this period, it was used experimentally to treat a variety of conditions, including alcoholism, anxiety, and depression.

One notable example is a series of studies conducted in the 1950s and 1960s that used LSD to treat alcoholism. A meta-analysis of these studies, published in 2012, suggested that LSD may be as effective as or even more effective than conventional treatments for alcoholism.

Modern Research on LSD

In recent years, there has been a resurgence of interest in the therapeutic potential of LSD and other psychedelic substances.

A small study conducted by Peter Gasser and his colleagues in 2014 found that LSD-assisted psychotherapy could reduce anxiety in patients with life-threatening diseases. This double-blind, randomized, active placebo-controlled study was the first of its kind in over 40 years.

In 2016, the Beckley/Imperial Research Programme published a study showing how LSD changes brain connectivity and leads to a state of “ego dissolution,” findings that may have implications for its therapeutic uses.

Future Research Directions

Moving forward, there are many potential directions for research on LSD as a medicine. Here are a few possibilities:

  1. Depression: Researchers are interested in whether the self-transcendent experiences induced by LSD could help people with depression gain a new perspective on their problems and promote long-term changes in mood and outlook.
  2. Anxiety: Ongoing research is examining the potential of LSD-assisted psychotherapy to treat anxiety, particularly in individuals facing life-threatening illnesses.
  3. Post-traumatic stress disorder (PTSD): Some researchers speculate that LSD and other psychedelics may help people with PTSD by enabling them to confront and process traumatic memories in a safe and supportive setting.
  4. End-of-life distress: Studies are looking into the potential of LSD to alleviate anxiety, depression, and fear in people with terminal illnesses.

While these possibilities are exciting, it’s important to note that this is a challenging field of research due to the controversial nature of the substance and the need for strict safety measures. Nonetheless, if these challenges can be overcome, the therapeutic potential of LSD could be an important area of study in the future.

LSD, is an intriguing substance

LSD, is an intriguing substance that continues to captivate the scientific community, medical professionals, and the general public alike. As a potent psychoactive, its influence on the brain, primarily through the serotonin system, manifests in a kaleidoscope of altered perceptions, emotions, and thoughts, painting a unique experience for each user.

While it’s primarily known for inducing hallucinatory trips, the complexity of LSD’s impact reaches beyond mere sensory distortions. By interacting with the brain’s Default Mode Network, it can lead to profound psychological shifts, such as ego dissolution and a heightened sense of connectedness.

The potential benefits of LSD have sparked renewed scientific interest. Under controlled conditions, it could offer therapeutic avenues for mental health issues like depression, anxiety, and PTSD. Moreover, anecdotal reports hint at LSD’s potential to unlock creativity and promote spiritual awareness. However, these possibilities should be balanced with a cautious perspective, given the substance’s non-addictive yet potentially disruptive nature.

Despite its lack of physical addiction, the unpredictable and intensely personal nature of LSD experiences can lead to distressing situations, commonly referred to as ‘bad trips’. Furthermore, its potential to exacerbate pre-existing mental health conditions poses a significant risk.

Lastly, it’s crucial to remember that LSD’s legal status remains a considerable hurdle. Its production, sale, and use are illegal in many jurisdictions, raising both ethical and legal concerns.

In essence, while LSD is a powerful tool capable of reshaping our perception and potentially providing therapeutic benefits, it’s a tool that should be wielded with extreme caution. The importance of responsible use, professional guidance, and legal adherence cannot be overstated when discussing LSD.



And as a summary here are some frequently asked questions about LSD

Is LSD Addictive?
LSD is not considered to be physically addictive, as it doesn’t cause physical withdrawal symptoms like some other drugs. However, individuals can develop a tolerance to LSD, requiring higher doses to achieve the same effects. Psychological dependence can also occur.

How Long Does an LSD Trip Last?
Typically, the effects of LSD can be felt for 6 to 12 hours, depending on the dose and individual. However, some effects, such as changes in perception, can last longer.

Is LSD Dangerous?
While LSD is not toxic in the traditional sense and it’s very rare to die from an LSD overdose, it can lead to risky behaviors due to its effects on perception and judgment. It can also have serious psychological effects, particularly in those predisposed to mental health conditions.

Can You Have a “Bad Trip” on LSD?
Yes, people can have negative experiences, known as “bad trips”, while under the influence of LSD. These can involve feelings of anxiety, paranoia, fear, and panic. The risk of a bad trip can be reduced by careful attention to “set and setting,” or one’s mindset and the environment in which the drug is taken.

What’s a Flashback?
A flashback, or Hallucinogen Persisting Perception Disorder (HPPD), is a re-experience of the perceptual disturbances caused by LSD, happening days or even months after the drug was last taken. While not common, it can be distressing.

Can LSD be Used Therapeutically?
Recent research has shown promise in using LSD, under professional supervision, as part of psychotherapy for conditions like depression, anxiety, and PTSD. However, this is still an area of active research and LSD remains an illegal substance in many jurisdictions.

Is LSD Legal?
In most countries, LSD is a controlled substance and its manufacture, sale, possession, or use is illegal. However, the legal status can vary, so it’s important to know the laws in your particular region.
