As a Schedule III drug, ketamine is available for medicinal use with a prescription. It is sometimes used off-label for pain relief and can provide sedative effects. Ketamine intoxication can present similarly to PCP, methoxetamine, and dextromethorphan intoxication, all of which bind to the N-methyl-D-aspartate receptor. Also, providers should consider intoxication with alcohol, amphetamine, cocaine, LSD, MDMA, and salicylate, as well as delirium tremens from alcohol withdrawal. Malignant hyperthermia that develops after succinylcholine or volatile anesthetics such as halothane, and side effects from antihistamines like diphenhydramine and anticholinergics such as benztropine, can also mimic signs of ketamine intoxication.
We and our partners process data to provide:
The search concept combination can be displayed as ketamine AND (chronic OR long term OR abuse OR dependence OR known long term use effects OR induced adverse effects). While ketamine overdoses are not strongly linked to death, consuming large amounts of this drug can be fatal. With a diagnosis of ketamine-induced multisystem illness, he was advised to refrain from further drug abuse and was discharged to a community-based drug rehabilitation program. His general health steadily improved, and on a subsequent outpatient clinic visit 2 months later, he weighed 50 kg (a total weight gain of 8 kg).
What Is Ketamine and Should It Be Used for Addiction?
Disrupted learning and memory processing has long been related with ketamine use. It is hypothesized that ketamine blocks NMDA receptors on gamma-aminobutyric acid (GABA) neurons inside the thalamic reticular nucleus, which leads to disinhibition of dopaminergic neurons and increased release of dopamine. Currently, there is no specific treatment for treating every ketamine patient presenting peripheral toxicity. Interestingly, ketamine psychotherapy has been suggested to be a promising approach to treat addiction of other drugs.
Utah scraps untested lethal drug combination for man’s August execution
We included 16 studies in our review, totaling 440 chronic ketamine users with a mean ketamine use of 2–9.7 years and 2.4 grams per day, compared to 259 drug-free controls and 44 poly-drug controls. Five studies were based on the pregabalin wikipedia same sample (Liao et al., 2010, 2011, 2012, 2016, 2018). The included studies described structural gray matter and white matter differences, differences in brain functionality and differences in neurotransmitter receptor binding.
A study with 34 chronic ketamine users and 19 healthy controls found lower gray matter volume in the right insula, the left dorsolateral prefrontal cortex (DLPFC), the rOFC and the left inferior parietal cortex in ketamine users compared to controls (Hung et al., 2020a). Within the ketamine users group, adolescent onset users were compared to adult-onset users. Adolescent-onset users showed a significantly smaller left precuneus volume than the adult-onset group and the healthy control group.
They found lower functional connectivity of the default mode network in the orbital right inferior frontal gyrus, left anterior cingulate gyrus, paracingulate gyri, right superior temporal gyrus and bilateral vermic lobule VI of the cerebellum. In contrast, they found higher functional connectivity in the left middle occipital gyrus. 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.
Ketamine can alter numerous functions in the brain including color perception, memory, attention, cognition, reaction time, and sense of time and can produce psychological addiction. Chronic 6 ways adult children of alcoholics struggle later in life can produce toxicity to the gastrointestinal and urinary tract. Gastrointestinal changes include epigastric pain, hepatic dysfunction, and impaired gallbladder activity.

Central nervous system side effects such as agitation are less intense than those seen with PCP abuse. High doses may dangerously reduce breathing, lead to muscle spasms or weakness, dizziness, balance difficulty, impaired vision, slurred speech, nausea and vomiting, and severe confusion. Different amounts of ketamine will give different “highs.” A medicinal dose is usually around 1 to 2 milligrams for each kilogram of body weight.
- In rats, ketamine was found to acutely elevate presynaptic glutamate in the prefrontal cortex at AMPA/kainite receptors (Moghaddam et al., 1997), and prolonged ketamine exposure may provoke cell death by regional glutamate-induced excitotoxicity.
- However, choice of adjunctive therapy should also be informed by the symptoms of the patient population.
- Official data and reports on labor in the marijuana industry are sparse, and Chinese workers rarely talk about their experiences.
- In addition to its legal, medical uses, ketamine and synthesized analogs have become drugs of abuse with hallucinogenic properties.
Frequent critical issues were lack of reference to a registered review protocol, and lack of risk-of-bias analysis and consideration of risk of bias in the interpretation of findings. Urinary tract abnormalities are the most commonly reported chronic toxic effect related to is there a connection between narcissism and alcoholism. With chronic use, the drug injures the urinary bladder, causing ulcers, cystitis, and fibrosis leading to urinary incontinence, hematuria, bladder overactivity and shrinkage, and, in the later stages, hydroureter and hydronephrosis (2, 6). The term “ketamine bladder syndrome” has been coined to describe this clinical entity. The smooth muscle relaxing property of ketamine was thought to be a pathogenic mechanism of urinary tract disease. Ketamine itself or its active metabolites were believed to cause injury to the urinary tract, although adulterants in the abused drug preparation were proposed as the cause by some authorities.
Because ketamine is consumed in liquid and powder form, or mixed in these forms with other stimulants—there is a high chance that a person using this drug has little to no idea of how much is being consumed. Because of its addictive nature, this drug is more commonly used in veterinary clinics to sedate animals. Ketamine is available as an injectable liquid but is also abused in powder form. Ketamine can disrupt the senses, judgment, and motor function for up to 24 hours after use.
In my article, I tried to be careful to cite the downsides of this powerful drug (that addiction and bad trips were rare but did happen, and that ketamine didn’t work for everyone), even as other firsthand accounts occasionally gushed. Across all eight of our UKAT facilities, we provide rehabilitation programmes specifically tailored to your needs. So don’t let your ketamine addiction consume another moment of your life. Get in touch as soon as possible, and one of our advisors will discuss which programme is best for you. This paper is dedicated to the memory of our colleague, Professor Catharina Matheï, who unfortunately passed away when finalising the article.
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. One review56 and two meta-analyses57,58 focused exclusively on bipolar disorder, whereas the remaining 14 also reviewed unipolar depression. It must be noted that the reported changes were dependent on the dosage and duration of ketamine use which were substantially higher than for clinical use, so our findings cannot be translated to clinical ketamine use. A list of studies that appeared to meet the inclusion criteria but were excluded, and reasons for exclusions, are provided in Supplementary Table 1. Ketamine is a compound with many potential benefits for the treatment of mental disorders as well as many risks, making it a « hot topic » in the field of psychiatry.
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. In fact, Florida medical examiners, who meet every other month, have noted a drop in the presence of xylazine in drug overdose deaths in 2024. The increase of xylazine present in those who died from drug overdoses does have people worried. The drug was commonly known as a horse tranquilizer and a ’90s party drug.
In a previous post, I explored the research being undertaken in testing a ketamine nasal spray as a fast-acting antidepressant. This means people can reap the benefits of ketamine much faster than traditional antidepressants, which often take up to six weeks to have a clinical response. The early research suggested that ketamine could have an effect within just a few hours. “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.
They will instead seek out a drug that’s been used previously in executions in numerous states. But the report doesn’t give him enough information to pinpoint whether it was the test strips that helped curb overdoses, or naloxone, or the shift from injecting to smoking, or law enforcement initiatives or change in the supply. In Florida in the first half of 2023, data shows a 19% increase compared to the same months the prior year. The Jacksonville area saw the most deaths, with xylazine present in 76 out of 278 deaths statewide.
