This is a big concern with LSD because while it’s not considered a physically addictive drug, the user’s brain develops a tolerance for it quickly. First, LSD toxicity occurs when the dosage levels a person takes of the drug are too high for the body to metabolize. Since LSD affects the serotonin system of the brain, this also leads to problems in emotional functioning and stability over time. Also, there is a tendency by heavy LSD users to feel that their life isn’t going well if they’re not using the drug. They may feel like they can’t function in social situations without using LSD, and then they continue to take it to recreate their feelings and emotions they have during a trip. First, people who are regular LSD users can start to develop social problems.
Research has shown that having a trip sitter is one of the most effective harm reduction measures for psychedelic drugs like LSD.12,18 Using LSD can trigger or worsen mental health conditions such as anxiety, schizophrenia or psychosis.3,6 Anyone with a history of these issues should avoid using LSD. While a bad trip can feel frightening, it is generally not life-threatening and the effects will go away as the drug wears off.1,12-14 It is important to understand the difference between a bad trip and an overdose. This is mainly due to practical difficulties, such as the need for clinicians to monitor people for several hours while they are having a psychedelic trip, he says. We are committed to evidence-based addiction treatment, mental health care, patient safety, and long-term recovery.
The effects of acid are highly unpredictable and can vary greatly between individuals. If these symptoms appear, seek medical attention immediately. Common outcomes include a bad trip, where hallucinations and altered perceptions become terrifying. Typical recreational doses range from 50 to 200 micrograms.
How Dangerous is LSD?
- Its psychoactive effects were discovered in 1943 when Hofmann accidentally absorbed a small dose and later intentionally ingested more, leading to vivid hallucinations and perceptual distortions.
- The most common clinical effects of acid overdose are hallucinations, agitation, and tachycardia.
- There is a fine line between taking too much and taking the right amount, and similar doses may have drastically different effects on different people.
- However, detecting LSD in human tissues is more challenging due to its active dose being significantly lower (in micrograms) compared to most other drugs (in milligrams).
- ‘Trip sitting’ is when a sober person helps look after someone who’s taken a psychoactive drug, usually psychedelics like LSD or psilocybin.
Food and Drug Administration designated a form of LSD (MM120) a breakthrough therapy for generalized anxiety disorder. However, its association with the counterculture movement of the 1960s led to its classification as a Schedule I drug in the U.S. in 1970. It was used experimentally in psychiatry for treating alcoholism and schizophrenia. It was initially explored for psychiatric use due to its structural similarity to serotonin and safety profile.
A bad trip is very different from an LSD overdose. A bad trip can happen to anyone, especially if you take LSD in high doses. Despite acting as non-selective serotonin receptor agonists, major psychedelics like LSD and psilocybin do not cause serotonin syndrome even with extreme overdose. Flashbacks are psychological episodes where individuals re-experience some of LSD’s subjective effects after the drug has worn off, persisting for days or months post-hallucinogen use. Despite lower rates of depression and substance abuse found in psychedelic drug users compared to controls, LSD presents heightened risks for individuals with severe mental illnesses like schizophrenia.
- It was listed as a Schedule I controlled substance by the United Nations in 1971 and currently has no approved medical uses.
- For instance, if the treatment causes transient psychological distress, the FDA may deem that a tolerable side effect, but it probably wouldn’t for longer-term distress, says Nayak.
- However, according to statistics, LSD overdose has been very low, with 97 percent of all students have never used them.
- If you think it might be an overdose, get medical help right away.
- It is a Schedule I substance under the Controlled Substance Act.
- In rare cases, LSD can trigger psychosis, especially in people with underlying mental health conditions.
- Tolerance develops rapidly to the effects of LSD.
Does LSD Cause Long-Term Health Effects?
It has been said that there is a peculiar 40-minute lag before onset of the psychedelic effects of LSD when it is administered intravenously. These varying concentrations in different brain areas may explain the profile of psychedelic effects of LSD. The cryo-EM structures of the serotonin 5-HT2A receptor with LSD, as well as with various other psychedelics and serotonin 5-HT2A receptor agonists, have how to help an alcoholic father been solved and published by Bryan L. Roth and colleagues. LSD, like other psychedelics, has been found to increase the expression of genes related to synaptic plasticity and hence to have psychoplastogenic effects. The affinity and activational potency of LSD at the human serotonin 5-HT2A receptor in vitro is unremarkable compared to other psychedelics such as DOI and DOB.

Lysergic acid diethylamide (LSD) is a highly potent hallucinogenic drug that can produce mind and mood-altering effects.2,3 LSD is in a category of drugs often referred to as classic hallucinogens, or psychedelics. Keep reading to learn more about LSD, effects of LSD, health risks, overdose potential, and how to find LSD treatment near you. An overwhelming psychological experience can trigger dangerous behavior, especially in individuals who also have underlying mental health issues. “AV’s father observed that his daughter appeared to be completely recovered from her mental health concerns after the overdose incident,” the researchers write.
Siegel administered two similarly high LSD doses to a pair of African elephants. For two decades it was often cited as an indication of how toxic LSD could be, but this conclusion never took into account the effect of the extra drugs Tukso was subsequently administered. Over the following 100 minutes Tusko was injected with an anti-psychotic drug, and then a tranquilizer, but sadly the animal didn’t survive the experience. Animal toxicity studies exploring high LSD doses have delivered notably mixed results.
LSD for Depression: An Underrated Hallucinogen?
The drug also powerfully shaped the popular music of the 1960s and encouraged the mystical experimentation of those years. During the mid-1960s, use of LSD spread widely in the emerging counterculture, and the shapes and colours characteristic of LSD-induced trips appear frequently in the visual art of the period. Stanley’s efforts supplied the drug to several figures who would become advocates for LSD, including novelist Ken Kesey. During the 1960s LSD (“acid”) became popular within the hippie subculture that emerged in the United States and western Europe. Research projects continued under the supervision of the National Institute of Mental Health, a governmental agency. The following year the only authorized manufacturer of LSD in the United States withdrew the drug from the market and transferred its supplies to the federal government.
It’s difficult to assess how likely consuming tainted LSD is, although it is probably many times higher than suffering any harmful side effects from LSD directly. Additionally, while LSD itself is not toxic, users may consume contaminated LSD unknowingly since it’s an unregulated substance. Doses in this range are generally not considered “too much,” although they can still create unpleasant experiences. Clinical and anecdotal evidence suggests that the possibility of overdosing on LSD is unfounded, but that doesn’t mean that taking large quantities won’t lead to unpleasant effects. One minor point of the confusion stems from LSD-related deaths, cases where people have died with famous people with fas LSD in their system.
These drugs mainly affect serotonin receptors and cause vivid visual and sensory distortions. They are generally grouped into classic hallucinogens and dissociative drugs based on their effects and chemical structure. Hallucinogens like LSD are classified as mary jane drug psychoactive drugs because they alter mental state and perception. The cultural impact of LSD is evident in the vibrant art, music, and literature of the era, as well as in ongoing discussions about consciousness and mental health. During the 1950s and 1960s, LSD was widely researched in psychiatry for its potential to treat mental health disorders.
He discovered the hallucinogenic and psychedelic properties of the drug in 1943 when he accidentally took some himself. There are few, if any, deaths from taking too much LSD; however, the experience can still be psychologically damaging. If the use of LSD has become problematic, a consultation with a medical professional or addiction specialist could help someone avoid additional injury or health problems. On the other hand, an overdose involves a dangerous level of toxins in the body. A bad trip involves feeling anxious, paranoid, afraid, and seeing or hearing frightening things that are not real. In some cases, high doses of classic hallucinogens can lead to death, but this is rare.
LSD can potentially trigger or exacerbate pre-existing mental health conditions, particularly psychosis or schizophrenia, in predisposed individuals. If the person poses a danger to themselves or others, exhibits severe physical symptoms like seizures or extreme hyperthermia, or if their psychological distress is unmanageable, seeking emergency medical help is imperative. Lysergic acid diethylamide (LSD) is a powerful psychedelic substance that alters perception and thought processes. Most patients can be discharged once symptoms resolve, but those with ongoing altered mental status or medical complications may need to be admitted to a hospital for further observation and care.
From a physiological perspective, however, LSD is known to be non-toxic and medically safe when taken at standard dosages (50-200μg). LSD (lysergic acid diethylamide) was discovered almost 75 years ago, and has been the object of episodic controversy since then. If you’re ready to find addiction treatment options for yourself or a loved one, get started with our free nationwide rehab search tool. In order to receive an HPPD diagnosis, the symptoms need to cause clinically significant distress and impair a person’s functioning.6 These symptoms can continue to recur even years after a person has used LSD.3 Derived from lysergic acid, a fungus that grows on rye and other grains, LSD may be found in different forms, including small squares of absorbent paper (known as “blotters”), tablets, capsules, and in liquid form, all of which are typically ingested orally.4 LSD is commonly referred to as acid and, historically, has been given various other street names such as Stamp, Lucy, and Microdot.2
Only 1% of the drug was eliminated in urine unchanged, whereas 13% was eliminated as O-H-LSD within 24 hours. In an earlier 2016 study, intravenous LSD effects similarly peaked after about 1.7 hours. However, in the 2025 study, time to maximal effects was about 2.5 hours orally and about 1.2 hours intravenously.
Hofmann discovered its effects in humans on April 16, in 1943, after unintentionally ingesting an unknown amount, possibly absorbing it through his skin. LSD was the 25th of various lysergamides Hofmann synthesized from lysergic acid while trying to develop a new analeptic, hence the alternate name LSD-25. Swiss chemist Albert Hofmann first synthesized LSD in 1938 from lysergic acid, a chemical derived from the hydrolysis of ergotamine, an alkaloid found in ergot, a fungus that infects grain. They are lower-efficacy serotonin 5-HT2A receptor partial agonists and can notably act as hallucinogen antagonists against LSD. Maximum plasma concentrations are typically observed 1.4 to 1.5 hours after oral administration of 100 μg and 200 μg, respectively, with a plasma half-life of approximately 2.6 hours (ranging from 2.2 to 3.4 hours among test subjects).
Alexander Shulgin did not include experience reports of LSD in his 1997 book TiHKAL (Tryptamines I Have Known and Loved) due to the thousands of reports that already existed in the literature. An “afterglow” effect, characterized by an improved mood or perceived mental state, may persist for days or weeks following ingestion. Stanislav Grof has written that religious and mystical experiences observed during LSD sessions appear similar to descriptions in sacred scriptures of great religions of the world and the texts of ancient civilizations. LSD can catalyze intense spiritual experiences and is thus considered an entheogen. As of 2017, about 10% of people in the U.S. had used LSD at some point, with 0.7% having used it in the past year.
Only a few deaths occur due to a high intake of acid, as a user may have paranoid delusions, terrifying hallucinations, and long-term effects on mood or mental health. Two later-stage trials investigating LSD for treating anxiety are due to conclude in 2026, which could lead to the drug being approved for the common mental health condition Yes, many health insurance plans do cover treatment for LSD addiction under general substance use and mental health benefits. High doses also increase the risk of Hallucinogen Persisting Perception Disorder (HPPD) and other mental health complications. This increases the risk of bad trips, mental health issues, and risky behavior. These symptoms can be triggered by the original drug experience and may persist or reoccur over time, reflecting the lasting psychological effects of LSD.
Treatment Services & Modalities
People use LSD for curiosity, spiritual exploration, or recreational experiences. It was first synthesized in 1938 by Swiss chemist Albert Hofmann, who later discovered its mind-altering effects. It also provides information on accessing effective addiction treatment near you. The experience can be confusing or frightening for many individuals.
This means the acid you get might not be pure. Since LSD is an illegal drug, there’s no regulation on how it’s manufactured or sold. Acid can sometimes be laced with other dangerous substances. If you notice any of these signs in yourself or someone else after taking LSD, seek emergency medical help right away. When someone is tripping too hard, they might have poor judgment or make dangerous decisions. The effects can be so intense that you might not be able to sleep, even though you feel exhausted.
