LSD, or lysergic acid diethylamide, is a powerful hallucinogen known for its intense mind-altering effects. It’s made through a complex process involving both natural and synthetic ingredients, starting with lysergic acid from ergot fungus.
This article explains how LSD is made, its chemical composition, side effects, and risks associated with its regular use.
What Is LSD?
LSD (lysergic acid diethylamide) is a powerful man-made psychedelic drug that can cause intense changes in how you think, feel, and perceive the world. It’s chemically similar to the brain chemical serotonin and also related to other hallucinogens like the ones found in magic mushrooms and DMT.
LSD is derived from lysergic acid, which occurs naturally in a fungus called ergot. Scientists chemically attach two diethylamine groups to this acid to create LSD. Because part of it comes from nature and part is made in a lab, LSD is called a semisynthetic drug. [1]
Originally synthesized in 1938, its psychoactive properties were discovered in 1943. Research began to rapidly advance in the 1970s; however, legal and political pressures ended almost all scientific studies on the drug. More recently, however, studies have begun to be done on the therapeutic nature of LSD.
Some research indicates potential clinical uses for treating substance use disorders and mental health disorders. However, most of these studies weren’t done with proper testing standards and are inconclusive. More testing is needed to understand whether there is an actual correlation between addiction and/or mental health symptom improvement. Potential risks include worsening symptoms or causing relapse.
How LSD Affects the Brain
After someone takes LSD, usually by mouth, it travels to the brain and binds strongly to serotonin receptors, especially the 5-HT₂A type. These receptors typically respond to serotonin, a natural chemical that influences mood, sleep, and perception.
Scientists have found that LSD not only fits into these receptors but can get “locked in,” like closing a lid over the molecule. This “lock‑in” helps explain why LSD’s effects last so long, even when the drug itself has left the bloodstream.
When LSD activates the 5-HT₂A receptors, it triggers unusual signals in the brain. It mainly affects how sensory information from the senses is processed, changing how we see, hear, and think. [2]
Physical and Psychological Effects
Onset and Duration
Onset: Effects typically start 30–60 minutes after taking LSD orally, though they can begin as early as 20 minutes.
Duration: The main part of the experience lasts approximately 7–12 hours, but some effects may persist for up to 20 hours or even 24 hours in some instances.
Psychological Effects
LSD is known for hallucinations, seeing things that aren’t there, or hearing sounds differently. People may experience bright colors, moving shapes, and shifts in their thought patterns. These are called “pseudo‑hallucinations” because the person knows they’re not real.
Moods can swing widely; one might feel joy, wonder, or calm, but also fear, anxiety, or confusion. On the flip side, “bad trips” involve paranoia, panic, or a sense of losing control.
Physical Effects
LSD can also affect the body:
Heart rate, body temperature, and blood pressure may rise.
Pupil dilation can occur, causing the pupils to appear very large.
Other effects include sweating, jaw clenching, dry mouth, and possibly nausea or tremors.
Feeling physically restless, having trouble sleeping, or muscle tension are also common. Though not directly addictive, LSD can be intense and mentally exhausting, especially during long trips or difficult experiences.
What Is LSD Made Of?
LSD (lysergic acid diethylamide) is a semisynthetic hallucinogen made from lysergic acid, a natural substance found in a toxic fungus called ergot. The substance must be transformed through chemical processes in a laboratory to become LSD. Because of this, LSD is not a naturally occurring compound, but a fully man-made drug.
Key Ingredients & Precursors
Lysergic acid: A compound that occurs naturally in certain fungi, most notably ergot, which grows on grains like rye. This natural substance forms the foundation for LSD.
Diethylamine: A man-made chemical that, when combined with lysergic acid, results in the unique structure of LSD.
Other chemical agents: Because lysergic acid does not naturally transform into LSD on its own, various chemical processes are required to alter its structure. These processes involve hazardous and tightly controlled substances.
Purification methods: Illicit production typically uses chemical solvents and other tools to separate the desired product from impurities. These processes are often unsafe outside of professional laboratories and increase health risks for anyone involved.
Is LSD “Natural” or Synthetic?
LSD is a semisynthetic drug, meaning it’s partly natural and partly made in a lab:
Part natural: The starting compound, lysergic acid, comes from ergot fungus, a natural plant parasite. Fungi like this also grow on morning glory seeds and produce lysergic acid naturally.
Part synthetic: To become LSD, lysergic acid is taken through several chemical steps that don’t happen in nature. These steps include using activating agents, adding diethylamine, and purifying the product. Because of this, the final LSD molecule is manufactured in the lab and isn’t found in nature on its own.
How Is LSD Made?
LSD is a semisynthetic hallucinogen made by combining lysergic acid, usually derived from ergot fungus, with diethylamine. Lysergic acid is first chemically “activated” (e.g., via phosphoryl or thionyl chloride), then purified through a series of chemical processes.
Historical Discovery
LSD was first synthesized in 1938 by Swiss chemist Albert Hofmann at Sandoz Laboratories while researching compounds related to circulation and breathing. Its hallucinogenic properties were discovered later by accident in 1943. Today, LSD has no accepted medical use in the U.S., and its possession or manufacture is illegal. [4]
Chemical Challenges & Safety Concerns
Sensitivity: LSD is sensitive to light, heat, moisture, and oxygen. It can convert into iso-LSD, an inactive form, if storage or reaction conditions aren’t ideal.
Hazardous chemicals: Many reagents, including thionyl chloride and diethylamine, are toxic, corrosive, or flammable. Risks of synthesizing LSD include physical harm via explosion, chemical burns, and more, and can result in severe injury or even fatality.
Illicit Lab Conditions
In unauthorized labs, conditions are often far from ideal. Without proper controls, contamination is common, reducing LSD purity and increasing health risks. Accidents like chemical spills, solvent vapors, or unintended chemical reactions are more likely in these setups. Successful production demands significant expertise, equipment, and stringent safety protocols.
Dangers of LSD Abuse
While LSD isn’t physically addictive or typically fatal, it carries serious risks. From chemical hazards during production to intense psychological harm like bad trips, flashbacks, and persistent visual effects (HPPD), abuse can lead to trauma and disrupted lives, especially when purity and mental health aren’t assured. [5]
Health and Safety Risks
Even before people take LSD, serious dangers exist during its production:
Chemical injuries: Chemical hazards in illicit labs, exposure to toxic, flammable, and corrosive substances, can cause burns, poisoning, or respiratory damage.
Toxin ingestion: Without quality control, impurities or incorrect doses are common. Users may unknowingly ingest unknown chemicals or harmful byproducts, putting their health at risk.
These risks mean that using LSD made outside certified laboratories can expose individuals to unpredictable and dangerous substances.
Psychological Risks and Addiction
Even though LSD isn’t physically addictive, it poses real psychological threats:
Adverse Psychedelic Episode or “Bad Trips”
These intense experiences can include overwhelming fear, panic, paranoia, and confusion. They can be deeply traumatic and leave long-lasting emotional scars.
Flashbacks & HPPD
Some users re-experience LSD-like visuals or distortions later, sometimes long after use.
Up to 50% report occasional flashbacks, with 1–3% developing persistent hallucinogen-persisting perception disorder (HPPD), causing ongoing visual disturbances like halos, trails, or visual snow.
Personal accounts describe nightmares, altered perceptions, and disrupted daily functioning due to HPPD.
Psychological dependence
While you can’t get physically hooked, regular LSD use may lead to craving the drug for emotional relief, increasing tolerance, risky behavior, and neglect of daily responsibilities.
Overdose and Adverse Reactions
LSD overdoses are rare and not usually fatal, but they can still be dangerous:
Toxic effects at high doses can include dangerously high body temperature, vomiting, breathing difficulty, coma, and hyperthermia, but with medical care, people typically recover.
More common are severe psychological reactions, such as panic, psychosis-like feelings, disorientation, or self-harm, during bad’ trips.
Because street LSD can contain unknown substances or vary greatly in strength, accidental overdoses are more likely during recreational use.
Legal, Ethical, and Scientific Context
Since the mid-1960s, LSD has been classified as a Schedule I controlled substance under the U.S. Controlled Substances Act. This means it is considered to have a high potential for abuse and no accepted medical use, making it illegal to manufacture, possess, or distribute outside of authorized government-approved research. [6]
Researchers face significant legal and regulatory hurdles in conducting studies due to this strict classification. Licenses from the Drug Enforcement Administration (DEA) and Food and Drug Administration (FDA) are required, and substances must be obtained under strict controls. As a result, clinical trials involving LSD are rare, expensive, and tightly restricted.
Renewed Research Interest
Despite its Schedule I status, interest in LSD for medical research has grown in recent years. Modern clinical studies demonstrate that controlled doses can produce positive effects on mental health.
A 2020-2022 review found that LSD helps reduce anxiety and increase emotional connection, openness, and empathy in healthy participants and patients.
Clinical trials by biotech firm MindMed found that 100 µg of a salt form of LSD (MM120) helped nearly half of the participants achieve remission from generalized anxiety disorder within 12 weeks.
Studies also suggest LSD may help treat cluster headaches and migraines, with ongoing controlled trials investigating its effectiveness.
How Is LSD Made?: FAQs
Is LSD considered a natural or synthetic drug?
LSD is a semisynthetic drug. This means it’s made using both natural and artificial ingredients. It starts with lysergic acid, a natural chemical found in ergot fungus, but is then chemically changed in a lab to create the LSD compound.
What other chemicals are used in the production of LSD?
Along with lysergic acid and diethylamine, making LSD involves lab chemicals like thionyl chloride or phosphoryl chloride (to activate the acid). Solvents like chloroform, ether, or methanol are used for purification.
Can you identify pure LSD by its taste or color?
No. LSD is usually colorless, odorless, and tasteless in the tiny doses used for a trip. Street products are often placed on blotter paper, gels, or tablets that may contain other chemicals, so visual or taste tests can’t confirm purity.
How long does LSD stay active in the body?
The main effects last 7–12 hours, but the drug itself is typically cleared from the bloodstream within a day. However, indirect effects, such as sleep problems or mood changes, can persist for another 24 hours or more.
Are there any approved medical uses for LSD today?
Not yet. Although early studies show promise for treating anxiety, depression, and certain headaches, LSD remains experimental. All legal research is done under strict government oversight, and it isn’t available as a prescription medication.
Can frequent LSD use cause permanent mental health issues?
While LSD isn’t physically addictive, repeated use can raise the risk of flashbacks, persistent visual disturbances (HPPD), or triggering underlying conditions like anxiety and psychosis. People with personal or family histories of mental illness are especially vulnerable.
