Addiction to substances such as ketamine is characterized by an inability to stop despite negative consequences, preoccupation with the substance, and disruptions that interfere with important aspects of life. When people try to stop using ketamine, they may also experience symptoms of withdrawal. While ketamine overdoses are not strongly linked to death, consuming large amounts of this drug can be fatal.

Structural Differences: White Matter

If substance misuse disrupts work, school, and personal relationships, it can indicate a ketamine addiction. While users report feeling complete bliss on ketamine, consuming high amounts of this drug can produce effects similar to a near-death experience. The patient was further managed with oral and intravenous hydration, a multivitamin supplement, and omeprazole. The acute kidney injury and the liver function abnormalities improved gradually (Table 1). He gained 3 kg body weight within a week of inpatient medical treatment. On examination he looked dehydrated and cachectic, and his sclerae were mildly icteric.

Also, white matter changes in one of these studies preceded more widespread cortical atrophy with longer ketamine use, supporting that axonal cells are most vulnerable for glutamate-induced excitotoxicity by ketamine. However, these observations are still based on comparison between subjects rather than longitudinal data. Ketamine is a phencyclidine derivative that is licensed for anesthetic use in humans and in veterinary medicine, especially in developing countries. At higher doses, ketamine produces a dreamlike state, hallucinations, distorted visual perceptions, a sensation of a near-death experience, amnesia, and delirium, making it a favorite recreational agent of drug abuse (3). “Special K,” “Vitamin K,” “K,” “kit-kat,” “keets,” “super acid,” “super K,” “cat valiums,” and “jet” are the terms used by drug abusers for recreational ketamine.

1. Ketamine in its liquid form can be easily mixed into an alcoholic beverage or added to marijuana joints.
2. In rats, different 5–7-days dosing regimens of ketamine yielded opposite effects on cognitive tasks in which the rats had to detect novel objects, or novel placement of objects.
3. They may also experience numbness, impaired vision, and severe confusion that often leads to aggressive behavior, amnesia, and delirium.
4. Concerns about active placebos are that they may have unintended treatment consequences; for example, in studies for anxiety, where benzodiazepines are used as a treatment.

Ketamine Effects And Abuse

When higher doses of ketamine are abused, or during emergence, it is reported to produce vivid dreams and an “out-of-body”, “K-hole” or “near-death” hallucinogenic experience, often reported as terrifying (similar to bad LSD trip). When abused, it is typically insufflated (“snorted” up the nose) in social situations. It is also injected, consumed orally as a liquid (mixed into drinks), or smoked in marijuana or tobacco. It is frequently abused in combination with other substances, such as cocaine, MDMA or amphetamines. Ketamine has a relatively short half-life (the time required for active substances in the body to reduce by half). Within 3 hours, at least half of the active ingredients in ketamine consumed will have left the body.

“The medical benefits of ketamine far outweigh potential harm from recreational use.” —Marie-Paule Kieny, Assistant-Director General for Health Systems and Innovation at WHO. High doses of ketamine can cause an out-of-body experience called a K-hole. Ketamine — also known as Special K — is a dissociative drug that makes people feel out of control or detached from reality. The hallucinogen causes tolerance and cravings, but reports of ketamine dependence and addiction are rare.

Ketamine has been traditionally used as a surgical anesthetic, but it has also been shown to be effective in the treatment of depression and alcohol use disorders. Several factors determine how the body responds to ketamine, including the person’s height, weight, ketamine tolerance and health. The intensity and duration of the drug’s effects depend on the dosage and method of use. People use ketamine to feel euphoric, out-of-body experiences and other effects of hallucinogens. The drug is sometimes used to facilitate sexual assault because it causes sedation and memory loss. Ketamine is often combined with other drugs, which can make the negative side effects of ketamine even worse.

Patients who experience symptom relief after intoxication should have continuous monitoring for 1 to 2 hours after their last symptom resolves. The results were subdivided into structural differences in gray and white matter, functional differences and effects on neurotransmission. Given the limited number of included studies and diversity of outcome measures in the studies, the data was deemed not suitable for meta-analysis. Therefore, we performed a conceptual synthesis of these heterogenous results.

Ketamine is a noncompetitive antagonist of N-methyl-d-asparate (NMDA) receptor and has been long used as an anesthetic agent in humans and veterinary medicine. The present article reviews the epidemiology, pharmacology, neurochemistry, and treatment of ketamine abuse. Ketamine has a unique mood controlling property and a number of studies have demonstrated a significant and rapid antidepressant effect of ketamine. However, the therapeutic value of ketamine to treat psychiatric disorders faces a major challenge that ketamine also owns significant reinforcing and toxic effects. Disrupted learning and memory processing has long been related with ketamine use.

Depression, anxiety, post-traumatic stress disorder, and chronic pain are the big ones, but it’s also being marketed for other uses, ranging from Lyme disease to alcoholism to opioid addiction. As is often the case, enthusiasm and marketing have gotten ahead of the evidence. In light of these findings surrounding ketamine’s psychotherapeutic potential, we systematically review the extant evidence on ketamine’s effects in treating mental health disorders.

The studies that have been done, have been conducted in clinical setting, with a much lower dose than the doses that are used recreationally. However, given the scarcity of research on the topic, these findings are worth mentioning. The most frequently reported side effects of short term ketamine (hours/days) are related to the nervous system, such as dissociation, sedation, headache, dizziness, blurred vision and memory impairment (Short et al., 2017). Small case series of ketamine administration in various doses for up to one year in patients with MDD or chronic pain suggest that some of these neural side effects may remain with prolonged ketamine use (Cvrcek, 2008; Szymkowicz et al., 2013). Results of individual studies included in the synthesis were presented in a separate table for each psychiatric diagnosis.

Ketamine can produce a dissociative state and hallucinations and therefore is not commonly used in adult anesthetic practice. Because of the hallucinatory effects of the drug, recreational https://sober-home.org/ has been increasingly reported in recent years. We report a patient with chronic ketamine abuse who presented with severe cachexia, upper gastrointestinal involvement, hepatobiliary dysfunction, and acute kidney injury. The past two decades have seen the development of ketamine for treatment of a broad range of mental health conditions beyond depression.

In the first stage of the study, the researchers treated all the participants with 120 mg of R-107 every day for five days. Those whose symptoms had not improved left the study at this point, leaving 168 people to proceed to the second stage of the trial. Numerous avenues are ripe for exploration in future treatment approaches with ketamine. One area of interest is in creating trials to tackle the problem of comorbidities and multi-morbidities, which are often more representative of the psychiatric population at large, where ‘pure’ diagnoses are rare. The study is designed so that everyone who enters it can eventually receive psilocybin, he said.

Ketamine users also showed a higher connectivity between the pallidum and the bilateral cerebellum. Furthermore, in ketamine users, the putamen showed higher connectivity to the OFC, which correlated with duration of ketamine use. Also, the ventral striatum (VS) showed lower connectivity with the right superior temporal sulcus (STS) and the left superior frontal gyrus (SFG) which was mediated by higher scores on the Barratt Impulsiveness Scale (BIS-11) (Hung et al., 2020b). In a study by Hung et al. (2020a), chronic ketamine users compared to healthy controls showed higher functional connectivity between the left DLPFC and the right inferior frontal/superior temporal gyrus and the left OFC and the right insula/inferior temporal gyrus. Within the ketamine users group, adolescent onset users were compared to adult onset users.

It also lasts a short duration of approximately 30 to 60 minutes and so it doesn’t take hours to wear off like some other sedatives. Ketamine, as an intravenous (IV) anesthetic, has been used medically for sedation since 1970. It is also known as a veterinary medicine and animal tranquilizer and has gained popularity as a party drug because of the sense of the euphoria and sense of disconnection it creates in the user. High doses of ketamine can make a person lose coordination and consciousness. Most deaths related to ketamine use are caused by accidents, assault or other substance use.

It seems that ketamine abuse is becoming more common, with findings revealing that, compared with a decade ago, more and more people are abusing the substance. However, while many individuals might consider that using ketamine is harmless, it has both habit-forming and addictive qualities that can lead to dangerous consequences if not appropriately managed. As ketamine is often mixed with other drugs, such as cocaine and alcohol,3 the clinical manifestations of misuse are varied. It’s no surprise when you look at the risks of ketamine use that it may cause people to be concerned about its use in non-surgical treatments. However, when monitored, controlled, and individualized, the use of ketamine can be beneficial. It’s when the drug is not regulated and is misused outside of treatment purposes that it can cause long-term psychological and physical health problems.
