Short & Long-Term LSD Effects

LSD, also known as acid, is a synthetic hallucinogenic drug that can powerfully affect both the mind and body. While some people use it recreationally for its intense effects, the consequences can be unpredictable and potentially damaging.

This page explores the short and long-term effects of LSD, its risks, and the potential dangers associated with this potent Schedule I drug. You will also discover how to get effective, science-based treatment for substance abuse.

What Is LSD?

LSD – lysergic acid diethylamide – is a strong hallucinogenic and psychedelic drug that can cause profound changes in a person’s perception, mood, and thought processes. It was first synthesized in 1938 by Albert Hofmann, a Swiss chemist who was working with ergot, a fungus that grows on rye and other grains. Hofmann created LSD while researching possible medical uses for the ergot fungus. However, he didn’t discover its powerful hallucinogenic effects until 1943 when he accidentally ingested a small amount and experienced a strong, mind-altering trip.

LSD is most commonly found in the form of small squares of blotter paper that have been soaked in the drug. These squares are then placed on the tongue to dissolve and absorb through the skin. LSD can also come in liquid form, tablets, or gelatin squares called window panes. LSD is illegal in all forms in the United States.

Acid is so powerful that even a tiny amount can lead to intense experiences. The drug is measured in micrograms (mcg), with doses ranging from 20mcg to over 300mcg. For context, one microgram is one-millionth of a gram, so it takes very little LSD to cause a dramatic effect – this is why it’s considered one of the most potent mood-altering substances known.

LSD works primarily by affecting serotonin, a neurotransmitter that plays a role in mood, perception, and other vital functions in the brain. When someone takes LSD, it disrupts how serotonin communicates between brain cells, leading to the drug’s characteristic hallucinogenic effects. These effects can include seeing vivid colors, experiencing time distortions, and feeling like the boundaries between self and environment are blurred.

Is Acid Bad for You?

Acid can be bad for you. Short and long term effects of LSD can affect both body and mind. While some people may take LSD to experience what they see as a positive, mind-expanding trip, the risks may outweigh the benefits. The drug’s effects are unpredictable and can vary greatly from one person to another, which makes it dangerous, especially for those who are unprepared for its intensity.

LSD short term effects can be unpleasant or even dangerous. Physically, it can lead to increased heart rate, higher blood pressure, and a rise in body temperature. These changes can be particularly risky for people with pre-existing health conditions such as heart problems or high blood pressure. Beyond this, LSD can cause dizziness, loss of appetite, dry mouth, sweating, and tremors.

Psychologically, LSD can be even more unpredictable. While some people might experience euphoria and a heightened sense of understanding, many others suffer from intense anxiety, paranoia, and fear. The experience of a bad trip can be terrifying, causing people to panic, become confused, or feel disconnected from reality. In severe cases, a bad trip can lead to dangerous behaviors, including self-harm or aggression toward others.

One of the most concerning aspects of LSD is its potential for long-term psychological effects. Although LSD does not cause physical addiction, it can lead to a psychological dependence where a person feels compelled to take the drug repeatedly to recreate their initial experiences. Over time, this can contribute to mental health issues, including persistent psychosis and a condition known as HPPD (hallucinogen persisting perception disorder). People with HPPD continue to experience visual disturbances and hallucinations long after the drug has left their system.

What Are the Effects of LSD?

LSD affects people in different ways depending on factors like their mood, surroundings, and the dose taken – this is known as set and setting. The effects of LSD can be both physical and psychological, and they can vary greatly from one person to another.

Immediate Effects of LSD

When someone takes LSD, the drug’s effects usually kick in within 20 to 60 minutes. These immediate effects are usually the most intense and can persist for several hours. During this time, the person may experience a variety of physical and mental changes.

One of the most notable immediate effects of LSD is its impact on perception. People often report seeing vivid colors, geometric patterns, and strange shapes, even with their eyes closed. They might also experience synesthesia, a condition where the senses blend together, causing them to see sounds or hear colors. These visual and sensory distortions are what many people refer to as an acid trip.

In addition to altering perception, LSD can trigger major changes in a person’s emotions and thoughts. People using the drug might feel an intense sense of euphoria, accompanied by a feeling of being more connected to the world around them. That said, these positive emotions can rapidly become negative, leading to anxiety, fear, or confusion. Such sudden shifts in mood and thought patterns can be overwhelming and difficult to control.

Physically, the immediate effects of LSD include changes in heart rate and blood pressure, increased body temperature, and dilated pupils. Some people might feel restless or have difficulty sitting still, while others might feel heavy and sluggish. These physical symptoms can be uncomfortable and might contribute to the anxiety some people feel during their LSD trip.

Short Term Effects of LSD

What are the short term effects of LSD, then? These normally linger for between six and twelve hours, depending on the dose and individual body chemistry. During this time, people using the drug can experience a wide range of physical and psychological effects which can vary in intensity.

Mentally, LSD continues to affect a person’s thoughts and emotions long after the initial trip has begun. Many people find it difficult to focus or concentrate on tasks, and their thoughts might feel jumbled or disorganized. They may also experience changes in their perception of time, feeling as though minutes are stretching into hours, or that time is moving faster than usual.

Some of the more common short-term psychological effects of LSD include:

• Hallucinations: Seeing things that aren’t there or perceiving reality in a distorted way.

• Altered sense of time: Feeling like time is speeding up or slowing down.

• Euphoria or dysphoria: Intense feelings of happiness or sadness.

• Paranoia: Feeling suspicious or fearful without a clear reason.

• Confusion: Struggling to think clearly or make sense of the world.

Physically, the short-term effects of LSD can include increased heart rate, high blood pressure, and higher body temperature. People using the drug might also experience dizziness, nausea, sweating, and tremors. These symptoms can be uncomfortable and might contribute to the overall stress of the experience.

One of the major risks of LSD is the possibility of having a bad trip. This refers to an experience where the effects of the drug are overwhelmingly negative, causing intense fear, anxiety, and distress. Bad trips can be traumatic and might have lasting effects on a person’s mental health. In some cases, the fear and paranoia experienced during a bad trip can lead to dangerous behaviors, such as attempting to escape from perceived threats or engaging in self-harm.

Long Term Effects of LSD

While LSD is not considered physically addictive, it can provoke an array of long-term effects, especially with repeated use. One of the most serious long-term effects of acid is the potential for persistent psychological problems, even in people who have only used the drug a few times.

HPPD is among of the most well-known LSD long term effects. People with HPPD experience recurring visual disturbances, such as seeing halos around objects, experiencing visual trails behind moving objects, or seeing flashes of light. These symptoms can occur days, weeks, or even years after the person last used LSD. HPPD can be distressing and can interfere with daily life, making it difficult for affected individuals to function normally.

Another long-term effect of LSD use is persistent psychosis, a condition characterized by ongoing mental disturbances which can include paranoia, disorganized thinking, and hallucinations. Persistent psychosis can be debilitating, making it hard for a person to distinguish between reality and their altered perceptions. This condition can be especially severe in people who have a history of mental illness or those who have used LSD frequently.

Alongside these psychological effects, repeated use of LSD can lead to tolerance forming quickly, meaning that the person needs to take increasingly larger doses to achieve the same effects. While LSD does not cause physical dependence, increasing tolerance can lead to more frequent use and higher doses, which in turn increases the risk of experiencing severe adverse outcomes like bad trips or long-term mental health issues.

Some people might also experience flashbacks, where they suddenly relive parts of a previous LSD trip without having taken the drug again. These flashbacks can be triggered by stress, fatigue, or certain environmental cues and can be unsettling or even frightening. In some cases, flashbacks can contribute to ongoing anxiety or other mental health problems.

Also, the long-term use of LSD can have a lasting impact on a person’s mental health and well-being. Even if the drug does not cause physical addiction, the changes it induces in the brain can lead to ongoing issues with mood, perception, and cognition. For some people, these changes might result in depression, anxiety, or other mental health disorders that require treatment.

Other Short Term Effects of Hallucinogens

Hallucinogens like LSD can cause a wide range of short-term effects beyond just visual changes. These effects can be both physical and psychological, and they vary depending on the set and setting.

• Mood swings: People might experience rapid changes in emotions, abruptly shifting from happiness to sadness.

• Distorted reality: Hallucinogens can cause people to see, hear, or feel things that aren’t actually there, making the world around them seem strange or even frightening.

• Nausea and dizziness: Physical discomforts like nausea, dizziness, and trembling commonly occur, especially during the peak of the drug’s effects.

• Increased heart rate: People taking acid often experience a faster heartbeat, which can feel uncomfortable and may lead to anxiety.

• Sweating and chills: Psychedelic drugs can also cause the body to sweat excessively or feel cold, adding to the overall discomfort of the experience.

Risks and Dangers of LSD

LSD is a powerful drug with many potential risks, some of which can be severe or even life-threatening. The effects are highly unpredictable, making every use a gamble – it’s safest not to use any Schedule I drug.

• Bad trips: People can experience terrifying thoughts, intense fear, and overwhelming paranoia, leading to dangerous behaviors.

• Lack of control: LSD’s effects vary widely, even with the same dose. This unpredictability can lead to frightening or harmful experiences.

• Risky behaviors: Under the influence of LSD, people might make unsafe decisions, such as driving or engaging in risky sexual activities, which increases the chances of accidents or injuries.

LSD Psychological Risks

LSD can have serious psychological effects, even after just one use. One of the most concerning risks is the development of persistent psychosis, a condition where a person experiences ongoing hallucinations, delusions, and disorganized thinking. This can make it difficult for them to function in daily life, as they might struggle to tell the difference between what is real and what is not.

Another psychological risk is HPPD, where a person continues to experience visual disturbances long after the drug has worn off.

Additionally, LSD can trigger or inflame anxiety, depression, and paranoia. People with a history of mental health issues are at heightened risk, but even those without such a history can experience these effects. The psychological risks of LSD are not completely understood, but they can have lasting impacts on a person’s mental health.

LSD Overdose Symptoms

While an LSD overdose is not usually life-threatening, it can still cause severe distress and requires immediate attention.

• Extreme agitation: Overdose can lead to intense restlessness, panic, and fear, making the person a danger to themselves and others.

• Psychotic episodes: The person may lose touch with reality, experiencing hallucinations and delusions that are hard to control.

• Physical symptoms: High fever, vomiting, difficulty breathing, and seizures can occur, requiring urgent medical care.

LSD Dependence

LSD does not cause physical dependence, meaning the body doesn’t crave the drug in the same way it might with substances like alcohol or opioids. However, people can develop psychological dependence on LSD, where they feel the need to keep taking the drug to achieve certain mental or emotional states. This can lead to repeated use, even if the person knows it’s harmful.

People who use LSD can develop tolerance, which means they need to take larger doses to achieve the same effects. This can increase the risk of experiencing negative effects, such as bad trips or long-term psychological problems. Although LSD is not addictive in the traditional sense, the desire to escape reality or achieve a specific mental state can drive people to use it repeatedly, leading to harmful patterns of behavior.

LSD Withdrawal Treatment

Since LSD does not cause physical dependence, there are no traditional withdrawal symptoms like those associated with alcohol or opioid use. That said, people who have used LSD frequently may still need support when they stop using the drug. This is because they might struggle with psychological distress, including anxiety, depression, or ongoing hallucinations.

Treatment for LSD withdrawal normally draws heavily on therapies like CBT (cognitive behavioral therapy). CBT helps people recognize then change the thought patterns and behaviors that lead to drug use. It can also help them develop healthier coping strategies for dealing with stress, anxiety, or other triggers that might lead them to use LSD.

In some cases, people who have experienced persistent psychosis or HPPD after using LSD may benefit from medications. These might include antidepressants or antipsychotics, which can help manage symptoms and improve overall mental health. Treatment should always be guided by a medical professional, though, as each person’s situation is unique.
