Hallucinogen Persisting Perception Disorder
Long-term LSD abuse can cause hallucinogen persisting perception disorder, a condition characterized by repeated, spontaneous distortions in reality similar to those caused by acid. People with HPPD may experience visual disturbances, such as halos or false motions in peripheral vision, months or years after they last took LSD.
- Flashes of color
- Lingering outlines of images
- Geometric patterns
The disorder can occur in people who take a range of psychedelic drugs, including MDMA and psilocybin. While it is often associated with prolonged hallucinogen use, HPPD has occurred in people after their first experience with hallucinogens.

Andrea Luppi Is First Author Of A Study On The Effects Of Lsd On The Brain
Our main finding is that the effects of LSD on brain function and subjective experience are not uniform in time.
LSD induces a profoundly altered state of consciousness, but the effects on the brain are more nuanced and complex than previously thought, according to a new study.
The study, whose first author is Gates Cambridge Scholar Andrea Luppi, is published in Neuroimage.
Andreas work is concerned with studying consciousness and LSD is known to profoundly alter peoples state of consciousness. He says that studying the psychedelic compound is a powerful way to understand how the mind interfaces with the brain.
Although the subjective stream of consciousness associated with LSD is not stable, no previous studies have investigated how the compound influences the dynamics of functional connectivity in the human brain.
The researchers focused on the two fundamental brain network properties of integration and segregation, looking at MRI scans of brain network properties affected by LSD and individuals subjective experiences.
Their main finding is that the effects of LSD on brain function and subjective experience are not stable in time and that LSD makes globally segregated sub-states of dynamic functional connectivity more complex and weakens the relationship between functional and anatomical connectivity.

Lsd Effects: What Does Acid Do To You
Users may experience various hallucinations and out of body experiences that can vary from positive to negative. Some have deeply spiritual and life-changing realizations, and others become completely terrified of what theyre experiencing .
After ingesting the drug, users tend to experience the erasing of normal filters or screens that their brains typically have on guard. When these are taken down, the outside world is expanded. A tremendous amount of information rushes to the brain.
Suddenly, users are exposed to everything that their brain normally filters out, including auditory, visual, emotional or sensory cues. Multiple factors, such as the people youre with and the physical setting youre in, can impact the feelings produced from your trip.

How Drugs Do What They Do
No matter what type of drugs you use, whether theyre pills prescribed by a doctor or something you bought on the street to smoke, they eventually find their way to your brain. Smoking, swallowing, snorting, drinking, injecting or any combination of these will all deliver drugs to your bloodstream, which in turn moves them to your brain.
Since your brain manages all functioning and thoughts, it makes sense that a drug would have to travel to your brain to have any effect. Consider an over-the-counter cough suppressant that relaxes the cough reflex, so you can get some sleep. That reflex is regulated by your brain, so the active ingredient in the cough medicine has to change the messages in your brain to be effective.
Once in your brain, drugs interfere with your normal brain chemistry to produce the desired effect. Because the brain is so complex, and our understanding of its functioning is not complete, drugs all have side effects, as well. The cough suppressant reduces your cough and also makes you drowsy. Every drug you take has more than one effect on you.
Usually, drugs affect you mentally and physically. While alcohol reduces your inhibitions, it also depresses respiratory functions, for example. Side effects can be the more dangerous part of any drugs since youre not looking for or monitoring them. Most people tend to focus on the primary function of a drug and try to ignore the side effects.

Physical And Psychological Effects From Lsd
Short-term effects from LSD begin within 30-90 minutes after it is ingested, which is often either in liquid form using a dropper or dried onto a piece of blotter paper and placed on the tongue. Initial effects from the hallucinogen are likely to last for 6-12 hours, depending on the size of the dose. These effects can include:
- Dilated pupils
- While serotonin syndrome is an acute risk, the effects of seizures or high fever can cause brain damage that will last for a long time. Brain damage may heal, with immediate and appropriate medical attention however, there is a risk that mood conditions, memory trouble, or learning disorders from brain damage may never go away.
- Drug-induced psychosis: LSD will not cause psychosis, but for people who are predisposed for this type of mental illness, the condition may be triggered by any potent hallucinogen, including LSD. It is important to understand ones family history as part of the risk associated with abusing drugs, including hallucinogens, which may be promoted anecdotally through popular culture as safe. There is no such thing as safe substance abuse.
- Psychosis can be treated, but it will not go away. Even bad trips on LSD will end, but a psychotic disorder is a chronic health condition that requires a combination of therapy and medication to prevent or manage severe symptoms.

What Does Lsd Do
Scientists believe that LSD works by influencing the receptors involved in the regulation of serotonin, a neurotransmitter in the brain. Serotonin is involved in the control of behavioral, perceptual, and regulatory systems including mood, motor control, sensory perception, hunger, body temperature, and sexual behavior.
When this system is disrupted by taking LSD, it can cause profound distortions in the person’s perception of reality, or in other words, hallucinations. People who use LSD see images, hear sounds, and feel sensations that seem real even though they are not.
These sensory hallucinations can be accompanied by rapid and intense emotional swings. Consequently, an LSD “trip” can go from being a pleasant experience to a very unpleasant one very quickly, making the effect of the drug extremely unpredictable.
Potential Health Benefits Of Acid
Several studies have looked at using classical psychedelics for the treatment of mental health conditions that do not respond to traditional treatment methods.
The studies included the use of psilocybin , ayahuasca, and LSD. Collectively, the seven studies looked at 130 people who had depression, anxiety, or both.
The participants experienced immediate and significant antidepressant and anxiolytic effects with the use of psychedelics. These effects lasted for several months.
The common side effects in these studies included headaches, nausea, slightly higher blood pressure levels, a higher heart rate, and transient anxiety.
Although the results sound promising, researchers must continue to investigate these preliminary findings. The Food and Drug Administration have not approved acid for these uses.
It is also important to note that LSD is illegal in the United States.

How Lsd Affects The Brain And Creates Its Trippy Effect
Were getting at the roots of a trip

Once you drop, you cant stop sometimes for up to 15 hours. Images revealing how LSD interacts with receptors in the brain could explain why a trip lasts so long, while another study involving a similar receptor unpicks how the drug makes these experiences feel meaningful.
LSD acts on with a number of different receptors in the brain, including ones for the chemicals serotonin and dopamine, but its not known exactly which receptors are responsible for its various effects.
Daniel Wacker and his colleagues at the University of North Carolina, Chapel Hill, used crystallography to look at the structure of LSD when it binds to a receptor in the brain that normally detects serotonin. They discovered that part of this serotonin 2B receptor acts as a lid, closing around the LSD molecule and trapping it.
This could explain the extended trips the drug produces. It takes LSD very long to get into the receptor, and once its stuck it doesnt go away, says Wacker.
However, there is conflicting evidence. Other studies have shown that LSD hangs around in the blood for a long time. No prolonged action at the receptor is needed to explain the duration of action, says Matthias Liechti at the University of Basel, Switzerland.
Effects Of Lsd On The Human Brain
During its short known existence, lysergic acid diethylamide has created quite a name for itselfprofound for some and obscene for others. The popularity and infamy of LSD is a rather mixed bag.
Its been used for everything from lab experiments to party drugs. LSD has also been tested on subjects in a wide range of applicationsfrom a medication to aid in the quest for mental health to a powerful weapon of war. Still, there is much to learn about this wonder drug.
On his deathbed from cancer, Aldous Huxley, the author of Brave New World, instructed his wife to bring a syringe filled with liquid LSD so that he could go on the worlds craziest trip. She gave him a 100-microgram shot of LSD and repeated that dosage one hour later. He died on what is probably the biggest dose of the powerful hallucinogen that the world has ever known.
But what was it like? What can science and studies of the brain tell us about how LSD makes us feel and how it alters our perception and experience? For those of you curious about these sorts of questions, here is a list of 10 things that LSD does to the human brain.

What Are The Risks Of Use
There are both physical and psychological risks to using LSD.
Impaired judgment on an LSD trip presents one of the greatest threats to the physical safety of the user. Poor decision-making or strange behaviors while on the drug can lead to physical injury or law enforcement intervention.2,3
A negative experience on LSD, also known as a bad trip, can be very unpleasant.
A negative experience on LSD, also known as a bad trip, can be very unpleasant. Users may have terrifying thoughts or feelings fear of losing control, insanity or death or severe despair. Other reactions include depressed mood or mental instability in the days after the experience.4
Users can also experience flashbacks of their LSD experience that can occur suddenly in the range of days to more than a year after last use. Flashbacks can happen without warning and include re-experiencing certain aspects of the trip.2
For some users, flashbacks can recur and interfere with their daily lives. In some cases, the perceptual disturbances experienced during a flashbacksuch as seeing trails on objectsmay persist for significant periods of time despite not having used the drug. This condition is known as hallucinogen persisting perceptual disorder.2
A Return To Innocence
As we become older, however, our brains become compartmentalized and fixed in their patterning. Depending on the individual, the way our brains function can lead to disfunction, obviously. Psychedelics have shown to get people out of their constrained ways of thinking about themselves and the world around them. In the case of depression, studies show that psychedelics such as psilocybin, ayahuasca, and MDMA break the loop of negative thinking and facilitate new patterns. Furthermore, research has shown that ayahuasca makes neuron babies in the brain. In other words, our world may be reborn on psychedelics.

The science of psychedelic experience
The current popularity of such writers as William Burroughs, Genet, and others, who specialize in the baroque recesses of human behavior, makes it seem as if, in this age of reason, we feel ourselves constrained within the confines of sanity and yearn for vicarious release.
The belief that in madness there may exist a core of numinous knowledge is a commonplace in all human societies. In the Western tradition, the doctrine that truth may be obtained through a state of mind in which reason is dislocated, a state of ecstatic revelation, is generally supposed to have originated with the Thracian worship of Dionysius, later becoming synthesized by Pythagorus, and to have received its most complete elaboration in the dialogues of Plato.
From the time of Dionysius to the time of Plato, the cultures of the Mediterranean consented to this doctrine that claimed the existence of an order of ultimate reality which lies beyond apparent reality, and that this “paranormal” reality is accessible to the consciousness only when the “normal” routines of mental data processing are dislocated. It was Plato’s pupil Aristotle who spoiled his master’s game. Following upon Aristotle, Western philosophy became bifurcated. The philosophical temper of our civilization, being scientifically and technically oriented, is basically Aristotelian.

Thinking About Taking Acid
Although taking LSD is known for being a fun and care-free drug that wont leave you addicted, its clear that its short- and long-term effects arent worth the trauma youre risking. Although you will experience a high for six to twelve hours, the drug will linger in your system for days after that, putting you at risk for lasting schizophrenic thoughts, intense fear and depression, complete confusion, chronic sleeplessness, an imbalance in body temperature and tremors.

Study Shows How Lsd Interferes With Brain’s Signalling
Scans of volunteers who took acid shows it disrupts information pathways in brain
A group of volunteers who took a trip in the name of science have helped researchers uncover how LSD messes with activity in the brain to induce an altered state of consciousness.
Brain scans of individuals high on the drug revealed that the chemical allows parts of the cortex to become flooded with signals that are normally filtered out to prevent information overload.
The drug allowed more information to flow from the thalamus, a kind of neural gatekeeper, to a region called the posterior cingulate cortex, and it stemmed the flow of information to another part known as the temporal cortex.
This disruption in communication may underpin some of the wacky effects reported by LSD users, from feelings of bliss and being at one with the universe to hallucinations and what scientists in the field refer to as ego dissolution, where ones sense of self disintegrates.
For the study, the researchers invited 25 healthy participants into the lab to be scanned under the influence of LSD and, on another occasion, after taking a placebo. They were shown around the scanner beforehand to ensure they felt comfortable going inside when the drug took hold. Had the machine suddenly taken on a threatening demeanour, the scans might not have come out so well.

What The Experts Say
Despite the fact LSD has been around for more than 70 years, there are few, if any, properly controlled research studies about the specific effects LSD has on the brains of those who use it. The research that does exist is comprised of smaller studies and case reports.
One review of the research on LSD that has been conducted over the last 25 years found that LSD:
- Enhances emotional empathy but impairs the ability to recognize fear
- Has therapeutic potential, but more research is needed
- Increases feelings of closeness and trust in others
- Increases interconnectivity in some brain networks
- Makes people more open to suggestion
There are a number of reasons why people use LSD despite the potential dangers. The hallucinogenic effects can seem pleasant. Because of the distorted perceptions and hallucinations that the drug can create, people often feel a sense of specialness or creativity, as if they are achieving an understanding that they could not normally reach without the drug.
The problem for people who use LSD is that all of these effects, pleasant or unpleasant, are so difficult to predict. The same dose of the same batch of LSD can affect one person in a completely different manner from another person. Moreover, a person can be affected differently from one trip to the next taking the same amount and same kind of LSD.
