Such findings include acute reduction in the recognition of fearful faces and identification of negative emotions in an ‘eyes only’ emotion recognition task (Bedi et al., 2010; Hysek et al., 2012), and slowed perception of angry expressions and an increased psychophysiological response to happy expressions after MDMA administration (Wardle & de Wit, 2014). Recently, some researchers have proposed that rather than MDMA neurotoxicity, the observed effects represent a neuroadaptive response to a foreign can you od on dmt stimulus (e.g., Kindlundh-Högberg et al., 2008). Nevertheless, the presence of persisting anxiety-like behavior in rats adminstered moderate doses (5–7.5 mg / kg) of MDMA do pose a potential risk in addition to concerns about neurotoxicity (Baumann et al., 2007).

Just as the health effects of hallucinogens are still being studied, so too are their potential drug interactions. Although study of hallucinogens’ effectiveness is ongoing, in 2019 the FDA did approve a psychedelic nasal spray called esketamine for use in treatment-resistant depression therapy. While the precise definition may still be up in the air, NIDA says hallucinogens include a wide assortment of drugs that alter a person’s thoughts, feelings and awareness of their environment. Some researchers classify all psychedelic and dissociative drugs as hallucinogens, while others think only some fall under this label. While each person experiences the effects differently, there are some common ways these drugs affect the body.

Psilocybin

Antagonism of the α3β4 nicotinic acetylcholine receptor has been proposed as a potential mechanism of action for ibogaine’s withdrawal attenuating effects (Pace et al., 2004; Taraschenko et al., 2005), as has agonism at the mu opioid receptor for which affinity has been demonstrated in vitro (Sweetnam et al., 1995; Glick et al., 2001). Underground ibogaine treatment centers and drug scenes eventually appeared both in Europe and in the United States (Alper, 2001). Finally, cannabis is sometimes attributed psychedelic-like properties (Keeler et al., 1971), and has exhibited therapeutic potential for a number of indications, which will be briefly presented. Furthermore, recent preclinical data have demonstrated that DXM exhibits antidepressant effects in animal models mediated by its activity at Sigma-1 and glutamatergic α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors (Nguyen et al., 2014; Nguyen & Matsumoto, 2015). Participants self-reported beneficial persisting effects at 1 month after multiple high-dose administrations of DXM, including increased spirituality, and positive changes in attitudes, mood, and behavior (Reissig et al., 2012). Ketamine’s hallucinogenic properties have been implicated as a mediator of antidepressant effects in some, but not all research.

LSD affects the interaction of serotonin and nerve cells to cause hallucinations, heightened senses, and other intense physical and mental effects. Some people may be interested in psychedelics’ spiritual or religious aspects, while others seek an altered state of consciousness. © 2026 treatmentsolutions.com is operated by American Addiction Centers, Inc. Take our free, 5-minute substance abuse self-assessment below if you think you or someone you love might be struggling with substance abuse. Hallucinogen effects may vary from intensely pleasant (“good trip”) to extremely unsettling (“bad trip”), depending on the dose taken as well as the user’s mood, character traits, and environment.4 They have the largest impact on the prefrontal cortex, a structure located at the front of the brain which regulates cognitive processes, perception, and mood.3

The effects of hallucinogens may result in part from their interference with the activity of brain chemicals such as serotonin and glutamate, according to the National Institute on Drug Abuse. If you or your loved one struggles with the effects of hallucinogenic drugs, help is available. Although more research is needed to understand all impacts, several long-term effects may continue well after hallucinogenic drug use stops. It is also vital to understand and identify the long-term effects of dissociative hallucinogens.

Long-Term Effects of Hallucinogen Abuse

However, some individuals may develop psychological dependence or exhibit patterns of problematic use, such as compulsive seeking or craving for hallucinogenic experiences. Hallucinogens affect the body by interacting with serotonin receptors in the brain, particularly the 5-HT2A receptors. Hallucinogens may have long-term effects that are still being studied.

• Other long-term effects of hallucinogens may include intrusive flashbacks and psychosis, which can occur in some people even after using a hallucinogenic substance only once.
• DXM is widely used, and has a high margin of safety, and low abuse liability at recommended antitussive doses (Bem and Peck, 1992; Gutstein and Akil, 2001).
• Some researchers classify all psychedelic and dissociative drugs as hallucinogens, while others think only some fall under this label.
• Its makeup varies with each lab that produces it, increasing its potential for fatal use.
• Use has been observed among some experienced users with an eventual return to oral use in most cases (Topp et al., 1999).
• LSD is a Schedule I drug under the Controlled Substance Act.
• People experience changes in moods (most often euphoria but sometimes depression), and their judgment becomes impaired.

All of these individuals showed a clinically significant reduction in CAPS score after their MDMA-assisted treatment. Common negative effects of MDMA-assisted psychotherapy included undesirable emotional symptoms such as anxiety during and following the session and undesirable physical symptoms such as jaw clenching. Recent neurobiological models for MDMA in the treatment of anxiety disorders have drawn on this body of work proposing three mechanisms by which MDMA may be an effective pharmacotherapy in the treatment of anxiety disorders. Some of these effects have been shown to be attenuated by pre-treatment with an oxytocin receptor antagonist (Thompson et al., 2007).

Bad Trips

Initial research on the long-term neuropsychological effects of ayahuasca (e.g., Grob et al., 1996) has continued in the 21st century with several teams conducting similar lines of research on a variety of ayahuasca using populations. Nevertheless, while data on pure DMT as a clinical aid are still lacking, ayahuasca, an indigenous DMT-containing formulation is receiving increasing attention as a potential tool in therapy. Although some research has been forthcoming examining the effects of mescaline in humans as a model psychosis (Hermle et al., 1992; 1998), clinical research investigating mescaline as a potential therapeutic aid has been lacking. However, further studies of psilocybin-facilitated treatment of substance use disorders are currently in progress, including randomized controlled trials investigating psilocybin as an aid in smoking cessation and alcoholism treatment, as well as a pilot study of psilocybin for cocaine dependence.

However, a growing body of evidence indicates that these drugs may have other applications beyond their potential for abuse. However, a growing body of evidence indicates that these drugs may have therapeutic applications beyond their potential for abuse. The effects of any drug (including hallucinogens) vary from person to person. Most users do not seek what is post-acute withdrawal syndrome paws treatment for the effects of hallucinogens. Hallucinogens are a versatile group of drugs, so there is a wide range of possible hallucinogen side effects on the body. Individuals who have had an intense hallucinogenic drug experience may report enduring psychological effects, including improved well-being and reduced symptoms of anxiety and depression.

Other results

• Long-term effects of many dissociative drugs continue to be studied.
• On some “trips,” users experience sensations that are enjoyable and mentally stimulating with a sense of heightened self-awareness and insight.
• A number of naturally occurring hallucinogens have a long history of use as religious sacraments dating back hundreds, and in some cases, thousands of years (El-Seedi et al., 2005; Guerra-Doce, 2015; Li, 1973).
• The long-term effects of hallucinogens can be just as harmful.
• Evidence has accumulated in recent years highlighting a relationship between a particular brain system and so-called ‘ego functions’ such as self-reflection (Carhart-Harris & Friston, 2010).
• In animal models this has been demonstrated with regard to particular behavioral effects such as the head-twitch response, as well as drug discrimination models (Fantegrossi et al., 2004, Carbonaro et al., 2014).
• This means that a person has taken more hallucinogen than their body can cope with.

However, these scales often focus on particular qualities or features of the drug experience such as intensity, affective response, feelings of unity, or a sense of oceanic boundlessness, to the detriment of other effects that are not specifically queried. High dose ketamine was found to produce greater levels of biologically verified heroin abstinence in all but two of sixteen follow-up visits including the final follow-up at 24 months after treatment. In the 1980s and 90s, over 1,000 alcoholic patients were treated with ketamine psychedelic therapy (KPT) without any complications such as psychosis or ketamine abuse (Krupitsky et al 1992; Krupitsky & Grinenko, 1997; 1998).

This means it acts on your brain (central nervous system) and changes your mood, behavior, and the way you relate to the world around you. It is an illegal street drug that comes as a white powder or clear colorless liquid. The centers note that although hallucinogen use disorder is a risk, it is uncommon. Hallucinogen use is increasing among Americans, and in 2019 there were 1.2 million new users, according to the Barbiturate withdrawal American Addiction Centers. “These interactions could pose major hurdles or increase the risks of psychedelic therapies.” For this reason, NIDA says that they may interact with medications that increase the serotonin levels in your brain.

All areas of a person’s life can be affected by drug use. The flashback experience can range from being pleasant to causing severe feelings of anxiety. An overdose of PCP or ketamine can result in depressed breathing, coma, convulsions, seizures and death. Not knowing the strength or purity of the hallucinogen increases the risk of overdose. A high dose of hallucinogen can cause a person to overdose.

The effects of hallucinogens on the body go beyond just seeing “trippy” images. Neural correlates of the psychedelic state as determined by fMRI studies with psilocybin. One of the most common yet abstract experiences described in relation to the hallucinogenic drug state is a disintegration or dissolution of the self or ego. Remarkably, in the 1950s and 60s, under the pretence of research on psychosis, such procedures were carried out in human subjects who were administered hallucinogenic drugs such as mescaline and LSD. Specifically, it fails to address some of the most prominent and intriguing psychological properties of hallucinogens, such as their ability to produce complex visual hallucinations (de Araujo et al., 2012) or ‘ego-disintegration’ in the promotion of ‘peak-type’ experiences (Griffiths et al., 2006).

This has been additionally demonstrated in humans in a double-blind placebo-controlled study showing that the nonspecific opioid receptor antagonist naltrexone, but not the selective 5-HT2A antagonist ketanserin, blocked the subjective and physioligcal effects of vaporized SA (Maqueda et al., 2016). Recent work using animal models of drug discrimination have further confirmed these findings (Butelman et al., 2010; Butelman et al., 2004; Killinger et al., 2010). The typical course of effects for inhaled SA is less than 20 minutes, with peak subjective effects achieved approximately two minutes after inhalation (Addy, 2012; Johnson et al., 2011, 2016). Recreational SD use tends to be sporadic, with most users reporting less than 20 lifetime uses (Baggott et al., 2010; Nyi et al., 2010) and the majority of recreational SD users surveyed report less than one use per year (SAMHSA, 2013; Khey et al., 2008). SD is controlled in 20 US states (Drug Enforcement Administration, 2012) and is listed as a “drug of concern” by the US DEA (Perron et al., 2012). The psychoactive compound contained therein, salvinorin A (SA) was not successfully isolated from the leaves of SD until 1982 (Ortega et al., 1982) and the psychoactive effects of SA were not confirmed until 1994 (Siebert, 1994).

If you’re interested in trying LSD, be sure to know your risks — both physical and legal —before you seek out the drug. It causes sensory disturbances similar to what you experience during a trip. You can expect the effects to linger for up to 24 hours after the bad trip begins. You may experience hallucinations that leave you terrified and distraught. In addition, though the risk of death and severe consequences from LSD is low, negative side effects are possible. If possible, allow a more experienced person to use it first and then take a smaller dose.

Hallucinogens also hinder the release of serotonin (the chemical responsible for regulating mood, sleep, sensory perception, body temperature, sex drive, and muscle control). If you want something to help with mental health issues or just to help you cope, consider talking to a professional before trying psychedelics. Regardless of use, you can develop a tolerance to psychedelics. These include anti-seizure medications, such as lamotrigine16 and clonazepam. There’s no treatment for HPPD, but research suggests certain medications may be effective.

However, safety and feasibility of psychedelic-facilitated treatment models have been established by these initial studies, paving the way for further investigation in larger, more diverse samples, using randomized controlled designs. Despite such broad potential, further clinical research with cannabinoids are necessary before definite conclusions can be drawn, with the current lack of evidence attributable in part to cannabis’ current Schedule I status (Grinspoon & Bakalar, 1998; Nutt et al., 2013). These data offer a compelling glimpse of some of the diverse therapeutic potentials of cannabis that will likely be explored in more depth over the coming years and decades, especially as greater access to medical cannabis, and development of cannabinoid-based treatments continue to proliferate. Preclinical evidence, case reports, and preliminary human data indicate that cannabinoids, and particularly CBD, may be useful in reducing seizures in epilepsy with limited adverse effects (Cunha et al., 1980; Devinsky et al., 2014; Maa & Figi, 2014). Additionally, medical access to cannabis in the US has been linked to a significant 24.8% decrease in average opioid overdose mortalities from 1999 to 2010 as compared to states without medical cannabis access, consistent with data on efficacy of cannabinoids for treating pain, and suggesting a potential role for cannabis as a means of reducing opioid abuse (Bachhuber et al., 2015).
