Psychedelic use does not conform to the profile of clinical features representing other types of dependencies, for example, opioids (Morgenstern et al., 1994). Psychedelics were considered to have high abuse potential simply because there were frequent reports of their use (Isbell and Chrusciel, 1970). We explore the evidence base for these adverse effects to elucidate which of these are merely based on anecdotes versus those that stand up to close scrutiny with current scientific methods. However, their potential range of psychological and psychiatric, as well as physiological risks remains to be fully understood. Although similar to LSD and psilocybin in its molecular composition and affinity for the 5-HT2A receptor (Rickli et al., 2016), DMT also possesses other unique characteristics (Garcia-Romeu et al., 2016), having been identified in human bodily fluids and in rats’ pineal gland (Barker et al., 1981). DMT has become increasingly widely used in Western society in recent years (Winstock et al., 2013), both as the vapourised and inhaled form and as a psychoactive component of the hallucinogenic brew, ayahuasca.
Are Psychedelics Addictive?
However, in unsafe and unmonitored settings, psychedelic use can, on rare occasions, also lead to fatal consequences, including suicide, but Zeifmann et al. (2021) stress the highly limited nature of their source literature, with the majority of the included studies being case studies or small case reports using retrospective data. In their systematic review, Zeifmann et al. (2021) examined the relationship between classic psychedelics and suicidality. With present safety protocols for psychedelic research, such occurrences are significantly less likely, although individual cases of serious adverse effects can and do occur.
Risks
Psychological research has since revived the use of psychedelics in experimental psychological treatment. This article discusses psychedelic substances, their history, and their different types. Neuroscientist Deborah Mash, professor of neurology and molecular and cellular pharmacology, Leonard M. Miller School of Medicine, has been studying the effects of ibogaine in substance-use disorders for more than three decades.
What Are Hallucinogens?
“In light of the federal illegality of psilocybin and ibogaine, there are many unresolved legal questions, some challenging legal questions and questions of potential liability, as well for licensed healthcare professionals who choose to get involved in these programs,” Marks said. Panelist Mark Guckel describes how psychedelics helped him overcome an addiction to crack. After reminding the audience that none of the information shared in the panel should be considered legal or medical advice, Tabashneck offered a word of caution about psychedelics. 17%Of Americans over the past year have struggled with substance use disorder yet only 10% have accessed treatment Microdosing refers to regularly taking these drugs in very small amounts, typically one tenth to one twentieth of a typical non-clinical dose.
- The approach of psychedelic-assisted psychotherapy (PAP) to psychiatric drug development is unique, a paradigm shift in fact.
- Psychological and psychiatric effects are less predictable and although rare, serious reactions can occur.
- Neurotoxic substances can kill brain cells, cause permanent cognitive damage, or alter the function of neurotransmitters in ways that may lead to long-term psychological harm.
Tolerance and Addiction
But the enthusiasm for psilocybin and ibogaine for treating substance-use conditions has been gradually increasing. There are also medication-assisted recovery treatments for opioid, alcohol, cocaine, and cannabis-use disorders. Conventional treatments for addiction include behavioral therapies, such as contingency management and medication compliance therapy. “Psychedelic therapy is not a replacement for medication treatments, like methadone for opioid-use disorder.

People have used hallucinogens for religious or healing rituals for many years. If you or someone you care about is seeking support for substance abuse and addiction challenges, we are here to offer our assistance. Opioids addiction treatment Overcoming hallucinogen addiction starts with stopping use and building a sober lifestyle.
Other NIDA Sites
Except where compelling, we avoided individual case reports for reasons outlined in detail by Krebs and Johansen (2013), such as the frequent failure to rule out pre-existing conditions or the use of other drugs, which could have contributed to adverse effects after psychedelic use. It is essential to address this issue now as psychedelics are increasingly shown to treat a broad range of hard to treat disorders, with the potential to treat many more. This article looks at the potential adverse effects of psychedelics, using the current science to outline risks as well as anecdotes surrounding harms. Despite an increasing body of research highlighting their efficacy to treat a broad range of medical conditions, psychedelic drugs remain a controversial issue among the public and politicians, tainted by previous stigmatisation and perceptions of risk and danger. For those considering psychedelic use, especially in a therapeutic context, these findings highlight the relative safety of these substances when used responsibly, with ongoing research providing a foundation for safer, more effective treatments.
- Griffiths et al. (2006) found that in a controlled study of healthy volunteers, high doses of psilocybin created extreme fear in 30% of participants, yet 80% of these participants also reported subsequent improvements in well-being.
- While researchers debate how to describe these drugs and how specific drugs should be classified, they generally group them according to what is known about how they work in the brain.
- While short-term positive and negative mood changes are common with psychedelic and dissociative drugs, more research is needed to better understand the long-term effects these substances may have on mental health.
- But before delving into their therapeutic applications, it’s crucial to establish a foundational understanding of what psychedelics truly are and how they differ from other substances.
- “Psychedelic therapy is not a replacement for medication treatments, like methadone for opioid-use disorder.
It’s also medically safe when you use it in a controlled setting. Mental health counseling and therapy can also help you learn how to cope with your symptoms. HPPD is a chronic neurological disorder that causes recurring flashbacks or hallucinations.
Assessing the risks of psychedelic use is challenging, as there are many different substances, applications, environments and population groups in this rapidly developing field. We focus on the effects of full psychedelic doses; for an in-depth review on microdosing psychedelics, please see Kuypers et al. (2019). We exclude n-BOMEs, 3,4-methylenedioxymethamphetamine (MDMA), ketamine and ibogaine, as these are distinguished from classic psychedelics, both in their effects and in their pharmacology. In Europe, a special use programme for d-lysergic acid diethylamide (LSD) and psilocybin has been established in Switzerland to provide compassionate access to (mainly major depression and post-traumatic stress disorder (PTSD)) patients not responding to other treatments (Schmid et al., 2021). Within the past 3 years, psilocybin and other organic psychedelics have been decriminalised in Denver, Colorado; Oakland, California; Santa Fe, California; Ann Arbor, Michigan; Somerville, Massachusetts; Washington, D.C.; and the state of Oregon. Taking a high-level perspective, we address both psychological and psychiatric risks, such as abuse liability and potential for dependence, as well as medical harms, including toxicity and overdose.
Psychedelic medicines are a rapidly developing area of clinical research (Nutt and Carhart-Harris, 2021) and public health policy. Our review shows that medical risks are often minimal, and that many – albeit not all – of the persistent negative perceptions of psychological risks are unsupported by the currently available scientific evidence, with the majority of reported adverse effects not being observed in a regulated and/or medical context. Still, individuals with a family history of psychosis or certain psychiatric conditions may be advised against using psychedelics due to these risks. Such experiences can induce intense fear, paranoia, or distress, which, in some cases, could exacerbate or trigger latent mental health conditions like psychosis or bipolar disorder. While psychedelics do not typically cause physical harm, they do present psychological risks, primarily in the form of “bad trips” or challenging psychological experiences. Psilocybin, for instance, has shown potential to help individuals quit smoking, while ibogaine, derived from a West African plant, has demonstrated effectiveness in interrupting opioid dependence.
Psychological and psychiatric effects are less predictable and although rare, serious reactions can occur. Most earlier shortcomings are being addressed in recent trials, that is, in randomised placebo double-blind studies (Carhart-Harris et al., 2021; Mitchell et al., 2021). A recent Freedom of Information request to the Office for National Statistics (ONS, 2021) confirms the remarkably low overdose rate of LSD and psilocybin. With adequate inclusion and exclusion criteria and clinical supervision, adverse physiological reactions are minimal (Malleson, 1971; Muttoni et al., 2019). However, the combination of MAOIs, such as that found in ayahuasca, with SSRIs has the potential to lead to serotonin syndrome (Gillman, 2010), highlighting the importance of educating ayahuasca drinkers of this potential risk. No difference in adverse effects was found between participants who used antidepressants and those who did not (31 participants reported using antidepressant medication).
Cannabis and hallucinogen use among adults remained at historic highs in 2023
You can also experience adverse effects from hallucinogens. This condition occurs when you take large amounts of ketamine withdrawal ketamine detox hallucinogenic drugs for an extended period. Most hallucinogens don’t cause physical addiction. These psychedelic drugs alter the user’s perceptions of reality.
Hallucinogen Persisting Perception Disorder (HPPD)
There is certainly a lot of potential, but many more studies are necessary to confirm the safety and benefits of using psychedelics as a medical treatment. More research is necessary to provide proof, but a few studies suggest that psychedelics may have a few uses relating to mental health and substance use disorders. Keep reading to learn more about the recreational and medical use of psychedelics, including the side effects and risks of these drugs. While hallucinogens are non-addictive substances, users can still abuse them.
PCP can also cause psychosis that persists for days to weeks.6,54 While it is not clear whether ketamine raises the risk of long-term psychosis, people who engage in regular recreational use of ketamine are more likely to experience delusions, even after weeks of abstinence.55 Animal studies show that long-term use of PCP or ketamine can cause brain changes resembling those seen in people with schizophrenia.56 Individuals also report using these drugs in the hopes of improving their mental health or well-being or easing pain or stress, but more research is needed to determine their effectiveness for these purposes.1,3,22 In June 2022, NIDA’s Office of Translational Initiatives and Program Innovations also announced a new program to support small businesses to develop psychedelic-based therapies for substance use disorders. NIDA also funds research on how and why people use these substances. This basic research plays an important role in identifying their health effects and potential therapeutic uses.
Dimethyltryptamine (DMT) is a naturally occurring plant-based psychedelic found in the bark and nuts of certain trees from Central and South America. Use of LSD has continued, despite being a controlled substance. Lysergic acid diethylamide (LSD) is a chemically synthesized hallucinogen, developed from ergot, a kind of mold that grows on the rye grain. Psychedelics are slowly reappearing in psychology and psychiatry as a viable way to treat anxiety, depression, post-traumatic stress disorder (PTSD), and more. It also covers their therapeutic potential and possible risks. Mash pleaded for more evidence-based research that could lead to regulatory approval and make such treatments safely available to those who are “suffering the most.” So far, what researchers have is anecdotal.
Shrooms are ‘magic mushrooms’ that contain the psychoactive ingredient psilocybin. Some dissociatives are illegal, but others have medical uses. DMT’s effects are intense and range from extreme anxiety and fear to complete peace of mind. DMT (N, N-Dimethyltryptamine) is a naturally occurring hallucinogenic compound. Morning glory seeds contain a hallucinogenic compound called lysergic acid amide (LSA).
Some psychedelic and dissociative drugs are also synthetic (lab-made).2 People report using psychedelic and dissociative drugs for a variety of reasons, including seeking new, fun, healing, or spiritual experiences.1,3 Research on the possible medical uses of psychedelics is still at a preliminary stage, but early studies suggest that psychedelics may decrease depression and anxiety. People with a history of a substance use disorder should not use psychedelics. Research from 2016 reports that psychedelics do not lead to dependence or addiction.
The U.S. Food and Drug Administration (FDA) has approved the ketamine derivative esketamine (under the brand name Spravato®) as a treatment for severe depression in patients who do not respond to other treatments.49 The FDA has also granted Breakthrough Therapy designation for two formulations of psilocybin being studied as potential medical treatments for depression. Some psychedelic drugs are derived from plants and fungi that have a long history of use in many different cultures around the world.23 Aztec shamans used psilocybin in healing rituals, and some Native American tribes used peyote as long ago as 5,700 B.C. People report using psychedelic and dissociative drugs for a variety of reasons. The DMN is most active during brain activity that’s related to self-awareness—such as reflecting on past events or making plans.19 This may account for why psychedelic drugs can make a person’s thoughts less self-centered and more expansive, promoting a sense of connectedness with others and the world.10 While dissociative drugs can alter perception, they also typically make people feel disconnected from their body and environment.6
