As of 2018, there were no established treatments for ketamine addiction and no medications approved by the Food and Drug Administration to treat addiction for ketamine or other dissociative drugs. Repeated use of ketamine, especially in large doses, can lead to memory loss, depression, stomach pain and ulcers, respiratory problems, seizures, psychosis, and gastrointestinal issues. High doses of ketamine may produce even more intense effects commonly referred to as falling into the K hole in which users are unable to communicate or move with memory loss a common occurrence.
However, it is a dissociative anesthetic and substance of abuse, chronic ketamine abuse can produce toxicity to the gastrointestinal and urinary tract. Computed tomography and endoscopic retrograde cholangiopancreatogram showed a dilated biliary system in patients who had a history of ketamine abuse for more than 1 year 84. Given that the effects of a single dose of ketamine were transient, another study assessed the efficacy of repeated doses for depressive patients.
- Conjugated hydroxylated derivatives of ketamine (80%) followed by dehydronorketamine (16%) are the most prevalent metabolites detected in urine.
- Although death from acute direct toxicity is rare, its chronic abuse can produce toxicity to the gastrointestinal and urinary tract 80, 81.
- In one of the included samples, 50% of ketamine users had also been using heroin, which could have contributed to the observed brain changes (Sanacora and Schatzberg, 2015; Chesters et al., 2016).
- In summary, the current literature supports the use of ketamine in carefully controlled medical environments, where its benefits can be maximized and its risks mitigated.
- Acute inhibition of the lateral habenula, a part of the brain responsible for inhibiting the mesolimbic reward pathway and referred to as the “anti-reward center”, is another possible mechanism for ketamine’s antidepressant effects.
- More recently, ketamine has emerged as a promising antidepressant (Berman et al., 2000; Zarate et al., 2012; DeWilde et al., 2015; Albuquerque et al., 2016; Singh et al., 2016; Daly et al., 2018).
Treatment is difficult, although cessation of ketamine use is always indicated.8 Over the last 10 years, case reports have surfaced regarding young patients with recurrent cystitis. In general, patients present with tachycardia and hypertension. Very high doses produce rockland recovery homes a state of profound detachment from reality, known as the ‘K-hole’. This produces a psychosis-like state at subanaesthetic doses,3 and the reuptake inhibition is also responsible for the commonly observed increase in heart rate and blood pressure.
Ketamine has anesthetic, hallucinatory, and dissociative effects similar to PCP but without respiratory depression and with a shorter duration of action. The medical examiner ruled that ketamine, typically used as a surgical anesthetic, was the primary cause of death. If you or someone you know is addicted to ketamine, contact professional medical help. This can increase the risk of dangerous side effects like respiratory depression and seizures.
When the anesthesia was maintained using nitrous oxide together with continuous injection of ketamine, the ketamine concentration stabilized at approximately 9.3 μM. In 1–5 teetotalism wikipedia minutes after inducing anesthesia by rapid intravenous injection of ketamine, its plasma concentration reaches as high as 60–110 μM. At similar plasma concentrations (70 to 160 ng/mL; 0.29–0.67 μM) it also shows analgesic effects.
Long-Term Effects of Ketamine
Therapy can help you overcome addiction and maintain long-term recovery. Ketamine addiction treatment often involves getting therapy and joining support systems. This can lead to ketamine dependence which makes your body need the drug to function normally. Taking too much ketamine can increase your tolerance for it, making you need more of it to feel the same effects.

Brain Changes Associated With Long-Term Ketamine Abuse, A Systematic Review
In this article, you’ll learn what ketamine is, its short-term and long-term effects, and how to toosie meaning drug seek treatment if you or a loved one are struggling with ketamine misuse. Over the past two decades, ketamine has emerged as a groundbreaking treatment for refractory depression and suicidal ideation, particularly in patients who do not respond to conventional antidepressants. Interestingly, ketamine psychotherapy has been suggested to be a promising approach to treat addiction of other drugs. Complete relief of the symptoms is observed in most cases when patients abstain from the drug.
- Sometimes, people use ketamine in conjunction with other drugs such as MDMA, amphetamine, methamphetamine, or cocaine.3 It can be additionally dangerous to use ketamine with other drugs.
- However, since subjects had to be abstinent from ketamine for only 48 hours, and since the direct effect of ketamine can last for more than 48 hours, the altered frontal network organization might also be a direct result of ketamine instead of a long-term side effect (Zarate et al., 2012).
- With a couple of exceptions, ketamine actions at other receptors are far weaker than ketamine’s antagonism of the NMDA receptor (see the activity table to the right).
- This discovery sparked additional psychiatric research on ketamine.
- One recent survey found that more than half of patients who attempted to take ketamine at home for depression either intentionally or accidentally took more than the prescribed amount.
Our treatment services are catered toward discovering and implementing solutions for sustained, long-term recovery. At Carolina Center for Recovery, we work with family members, co-workers and other professionals, as well as directly with the individual in need of support to provide comprehensive care and treatment for addiction. Getting started with addiction treatment may feel intimidating at first. Getting help can give people the tools they need to overcome addiction and move forward into a healthier future.
Reports of abuse and the dissociative and hallucinogenic effects of ketamine emerged in the 1980s. Edward and Toni Domino tested ketamine in humans, coining the term “dissociative anesthesia” to describe its unique effects. However, the drug Spravato, a form of ketamine and the first novel FDA-approved antidepressant in 50-plus years, is available , safe, and can be lifesaving when used appropriately, under supervision, in those with severe and nonresponsive depression. The actor had been using the drug through his regular doctor in a legal but off-label treatment for depression, which has become increasingly common.
Five studies were based on the same sample (Liao et al., 2010, 2011, 2012, 2016, 2018). For that reason, we compared the results if four of these five studies were left out of the analysis, to the situation in which all five studies were included. Bias could play a role, since the 5 studies by Liao et al. (2010, 2011, 2012, 2016, 2018) were based on the same sample.
Although ketamine has a currently accepted medical use, there’s potential for abuse, which can lead to low or moderate physical dependence and/or high psychological dependence. This guide explains the effects, trends, and dangers of ketamine use and provides an unbiased analysis of the medicinal and behavioral treatment methods for ketamine addiction based on current research and publicly available statistics. Note that ketamine is remarkable because of its unique mechanism, rapidity of action, antisuicidal effects, and ability to treat depressed patients for whom every other treatment has failed. Long-term ketamine use and addiction change the way your brain functions. In vivo, ketamine rapidly activates the mTOR pathway, promoting synaptogenesis and reversing stress-related synaptic deficits in the prefrontal cortex, which might underlie its fast-acting antidepressant effects in treatment-resistant depression. Additionally, the rapid onset of effects following insufflation may increase potential use as a recreational drug.
Yet the way it affects both the body and the mind explains why some people experiment with it, even as it carries heavy risks. It can sound strange to hear that anyone would want to use ketamine, especially when it has long been described as a horse tranquilliser. Supplying or producing ketamine carries even harsher penalties, with a maximum of fourteen years in prison, alongside fines. This means that possession of ketamine is illegal and can result in up to five years in prison, an unlimited fine or both. In the UK, ketamine is a Class B controlled substance under the Misuse of Drugs Act 1971. If you have a loved one who’s struggling with addiction, staging an intervention is often the first necessary step towards sobriety, but it’s important to be strategic and loving in your approach.
It remains unclear whether the altered connectivity patterns found in this study could be a direct result of ketamine. However, since subjects had to be abstinent from ketamine for only 48 hours, and since the direct effect of ketamine can last for more than 48 hours, the altered frontal network organization might also be a direct result of ketamine instead of a long-term side effect (Zarate et al., 2012). Participants in this study were asked to refrain from drug use 4–7 days before imaging was performed (Liang et al., 2020). Ketamine users that also used stimulants had even larger white matter structures, suggesting an additive effect of ketamine and these stimulants.
The CNS effects are mainly brought about by inhibition of the N-methyl-D-aspartate (NMDA) receptor, and, to a lesser degree, the catecholamine reuptake. Following ingestion, ketamine is rapidly distributed in the central nervous system (CNS) and its effects will last for up to 1.5 hours after insufflation. Due to its properties, the potential for misuse of ketamine was already there from its inception and contributed to its diversion. Although less prevalent, drug misuse in older adults should not be discounted.2 In general, much is still unknown about the epidemiology of ketamine, specifically regarding the frequency of its use and in what settings, and the trends over the years. When administered under medical supervision with pharmaceutical-grade products, ketamine has a safety net. The treatment takes place in a tightly controlled setting where side effects such as dissociation or blood pressure changes are carefully monitored by professionals.
Ketamine Addiction, Abuse, and Symptoms
Ketamine is a dissociative anesthetic drug that shares many chemical similarities with phencyclidine (PCP). He says ketamine benefits him. In contrast, the allegations concerning Elon Musk’s personal use of ketamine and other substances should be viewed with caution and concern. Its rapid antidepressant effects have opened new avenues for treating severe mental health conditions, yet its capacity to induce dissociative states and cognitive disturbances calls for cautious, supervised use.
Ketamine Use in Medical Settings
Naltrexone potentiates psychotomimetic effects of a low dose of ketamine, while lamotrigine and nimodipine decrease them. Some daily users reported withdrawal symptoms, primarily anxiety, tremor, sweating, and palpitations, following the attempts to stop. Ketamine tolerance rapidly develops, even with repeated medical use, prompting the use of higher doses. Although the incidence of ketamine dependence is unknown, some people who regularly use ketamine develop ketamine dependence. Most people who were able to remember their dreams during ketamine anesthesia report near-death experiences (NDEs) when the broadest possible definition of an NDE is used.
The desired action represents an efficacious approach to amelioration of major depression, treatment‐resistant depression, bipolar affective disorder, and suicidal ideation 9, 10, 11, 12, 13. The S (+) isomer, an active enantiomer 3, has a 4‐fold greater affinity for the NMDA receptor, twice the analgesic potency, and fewer psychomimetic effects than the R (−) isomer. This review highlights the recent clinical research that supports the therapeutic utility of ketamine as a multifaceted drug.
How ketamine affects the brain
Gastrointestinal changes in ketamine abusers include epigastric pain, hepatic dysfunction, and impaired gallbladder activity. Research also shows that ketamine abuse increases the risk of cognitive impairment and treatment-resistant depression. While some research into dissociative drug abuse exists, it is not enough to fully understand the long-term impact of ketamine abuse. Recreational ketamine abuse and misusing prescription ketamine can have severe short and long-term effects. Long-term ketamine users may develop a craving for the drug, leading to dependence and addiction.
