In the United Kingdom, where health data are more centralized, more than 2,000 people sought treatment for ketamine addiction in 2023. Low doses of ketamine have demonstrated promising antidepressant and anti-suicidal properties, offering hope for individuals who have not responded to traditional treatments. Esketamine, the ketamine-derived nasal spray sold under the brand name Spravato (esketamine), is indicated for patients with treatment-resistant depression.
We are a private drug and alcohol rehab offering confidential advice, assessments, and treatment options. Rehab Clinics Group offers residential addiction treatment that is tailored to your unique situation. Holistic treatments such as mindfulness, meditation, and physical therapy are used to boost mental well-being during the recovery process. Mental Health Disorders – Those with pre-existing mental health issues will find that sustained ketamine use only worsens the problems. A dependency can develop as you take ketamine to avoid withdrawal symptoms, which can keep the high going. Ketamine produces euphoria and, in lower doses, can act as a stimulant.
Research has not yet established the side effects of long-term ketamine therapy, but older studies of recreational users offer some insight on heavy, extended dosing. Across the country, bespoke ketamine clinics offer shots and lozenges to treat a wide variety of mental-health conditions, including anxiety and PTSD; some focus on IV drips at doses high enough that maintaining a conversation is not feasible. Last year, Musk told CNN’s Don Lemon that he has a ketamine prescription and uses the drug roughly every other week to help with depression symptoms. If patients have consistent and substantial improvement in symptoms for at least 4-6 months, they may opt to then stop ketamine/esketamine after a discussion with their provider. At the Interventional Psychiatry Service at Yale, where I work, we often find that a pattern of one treatment every 3-4 weeks is sufficient for helping patients maintain the treatment’s antidepressant effects.
Some people ‘bomb’ it, which is swallowing the powder wrapped in a cigarette paper. Some people swallow it in tablet form, but this is less common. They usually inject ketamine into a muscle. People who regularly use ketamine sometimes inject it to get a bigger hit. In the UK, snorting is the most common way to take ketamine.
Clinical Indications
- Ketamine can block muscarinic acetylcholine receptors, voltage-gated calcium channels, and descending monoaminergic pain pathways .
- When used at anesthetic doses, ketamine usually stimulates rather than depresses the circulatory system.
- Perry’s case is a tragic example of why it’s not a good idea for doctors to prescribe, or patients to take, ketamine at home—a practice that my colleagues and I have warned against.
- Since ketamine is not an opioid, overdoses cannot be reversed by Narcan (naloxone).
- Many studies have shown that ketamine is an effective drug for the treatment status asthmaticus.
- I knew that potential was there, but the ketamine just unlocked it for me — I could go into a meditative state within five seconds.”
- Factors such as the amount of drug taken, frequency of use, and individual metabolism can affect how long ketamine stays in the body.
That’s why it’s essential methamphetamine oral side effects to have medical supervision, and it’s very unsafe to be in water where you could lose awareness about where you are and drown. “Ketamine tends to make people feel very woozy. “Blood pressure surges with ketamine, and that can set off cardiac arrest,” Fehling said. Ketamine can elevate blood pressure, and there have been some high-profile deaths related to ketamine, like those of Perry and McClain. It has very strong response rates but also has strong side effects.” Another is electroconvulsive therapy for ECT.
The use of ketamine for general anesthesia or chronic pain in young children and pregnant women should be carefully considered as prolonged exposure can negatively affect fetal or young children’s brain development . The simultaneous use of ketamine and drugs that reduce liver metabolism by inhibiting CYP3A4 enzymes of the cytochrome P450 enzyme system (i.e., clarithromycin, ketoconazole) can increase the serum levels of ketamine with serious consequences. Although ketamine relaxes the bronchial smooth muscle, the drug may result in airway obstruction in 10–20% of pediatric patients, due to the risk of laryngospasm because of heightened salivation . Evidence suggests that long-term CNS depression is likely the result of an interaction between ketamine and gabapentin 125,126. Regarding psychiatric side effects, depression was found to worsen over a year in both daily and former ketamine users.

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. “We can’t predict with accuracy yet which patients will respond to which medication,” Fehling said.
What are the risks of using ketamine?
At UKAT, we provide specialist support for people facing ketamine addiction. Spotting the signs of ketamine addiction is crucial, especially if you or someone close to you is using the drug regularly. Clinics, both within the NHS and in the private sector, have noticed the shift, reporting steady increases in people, especially younger people, seeking help for ketamine addiction. “There are plenty of opportunities to get the FDA-approved esketamine or the generic ketamine in clinics where the drug can help resolve depression.” Fehling does not administer ketamine at CeDAR, but said it can be valuable for patients who are dealing with addiction and depression. Despite the challenges of ketamine, Fehling said medical experts welcome new therapies to help people who are coping with depression and have not responded to anti-depressants.
It is estimated that there are currently hundreds to thousands of these clinics — almost all of which were established in 2019 when ketamine was approved for treatment-resistant depression. First, it’s important to remember that ketamine isn’t a first-option treatment for depression. A prescription version of ketamine called esketamine (Spravato), given through a nasal spray, was approved in 2019 by the FDA for hard-to-treat depression. More recently, it has been widely used for treatment-resistant depression (TRD) — that is, severe depression that has not improved with several other therapies, including people who are experiencing suicidal thoughts.
Perry’s case is a tragic example of why it’s not a good idea for doctors to prescribe, or patients to take, ketamine at home—a practice that my colleagues and I have warned against. The amount of ketamine found in Perry’s deceased body was fairly high (anesthetic level), to the point that it would have caused him to lose consciousness. The most important one is that ketamine/esketamine should be administered while the patient is in a clinic (as opposed to at home). When friends and family who are depressed ask me if they should seek out ketamine as a potential option, I tell them that it doesn’t make sense unless they have tried oral antidepressants.
There are many risks, and it is essential to know them, as well as how ketamine affects you and what support is available if you are struggling. MDPI and/or the editor(s) disclaim responsibility for any injury to people or property resulting from any ideas, methods, instructions or products referred to in the content. This is a good example of how an existing drug with a relatively stable and established use in clinical practice can be repurposed for multiple uses. Ketamine is a non-competitive NMDA receptor blocker that is often used in human and veterinary medicine under strictly controlled conditions as an analgesic and sedative agent. If tachycardia, hallucinations, and hypertension do not improve within 2–3 h with the above treatment, they should be treated accordingly 153,154.
- However, changes in 11C raclopride binding may be due to changes in dopamine concentrations induced by ketamine rather than binding of ketamine to the D2 receptor.
- On the contrary, another study concluded that ketamine did not have an anti-suicidal effect on bipolar disorder and did not demonstrate effectiveness for remission in bipolar depression 93,94.
- Perry died in October 2023 from the “acute effects of ketamine.” He was 54.
- If you are one of those people that absolutely loves ketamine, why?
- While ketamine is marketed legally in many countries worldwide, it is also a controlled substance in many countries.
With drug use comes impaired judgement – meaning you’ll do things you usually never would. As ketamine changes how you perceive reality, this can impact your motor function and reaction time, increasing the chances of accidents occurring, such as car accidents or falling. Depression, anxiety, and psychosis can all be made worse by recurring ketamine use. Ketamine can cause increased heart rate and blood pressure, putting more strain on the organ – which is especially dangerous to people with pre-existing heart conditions. This means that you have to take more to achieve the same effects as before.

Ketamine is a dissociative anesthetic that works by blocking signals between the brain and the body, resulting in pain relief and a trance-like state. Ketamine is a powerful anesthetic and pain-relieving medication that has gained popularity for its recreational and therapeutic use. (Recreational use has shot up over the past decade too.) Some providers pair low-dose injections with talk therapy. In the 1990s, as a street drug known as Special K, ketamine took ravers to euphoric states.
As the dose increases, it becomes what we call a “dissociative anesthetic,” which means the central nervous system becomes almost disconnected from the body. What are some of the psychiatric and physiological effects of ketamine? But to try and get a deeper understanding as to why people take ketamine to go clubbing, THUMP reached out to an expert. Ketamine/esketamine is not a cure-all or “magic bullet” that will somehow alleviate all of a suffering patient’s problems.
The active metabolite of ketamine, hydroxynorketamine, does not demonstrate notable interactions with the NMDA receptor. AMPA receptor activation induces downstream effects, leading to the upregulation of brain-derived neurotrophic factor (BDNF) and the activation of the signaling receptor tropomyosin receptor kinase B (TrkB) . In the spinal cord’s dorsal horns, the antagonistic effect on NMDA receptors results in interference with pain transmission, leading to profound analgesia and prevention of central sensitization 16,17. It demonstrates a four-fold higher affinity for the NMDA receptor, along with twice the analgesic potency and fewer psychomimetic effects compared to the R (−) isomer.
Originally derived from PCP, or “angel dust,” ketamine has been Bipolar disorder and alcohol used in hospitals and veterinary clinics as an anesthetic for decades. If you or someone else needs urgent help after taking drugs or drinking, call 999 for an ambulance. People who use ketamine regularly can develop a tolerance to it, which could lead to them taking even more to get the effects they’re looking for. Others will attend drug treatment services to help them stop. People who become addicted to ketamine will keep taking it – whether they’re aware of the health risks or not.
The typical symptoms of ketamine-induced cystitis are frequent urination, dysuria, and urinary urgency sometimes accompanied by pain during urination and blood in urine. In February 2022, the US Food and Drug Administration (FDA) issued an alert to healthcare professionals concerning compounded nasal spray products containing ketamine intended to treat depression. There can you od on dmt were 18.7% (4.1 to 40.4%) more people reporting some benefit and 9.6% (0.2 to 39.4%) more who achieved remission within 24 hours of ketamine treatment. Esketamine was approved as a nasal spray for treatment-resistant depression in the United States and elsewhere in 2019.
In 2023, the FDA warned patients and healthcare providers about potential risks of using compounded ketamine products to treat depression or other psychiatric disorders. The effectiveness of ketamine nasal spray for TRD was first demonstrated for short-term treatment in research that showed meaningful decreases in depression scores for the group given ketamine over the group that received a placebo. There are no physical withdrawal symptoms with ketamine, so ketamine addiction is sometimes called a psychological dependence. We apply a holistic and evidence-based approach to treatment, using medically supervised detox, therapy and rehab programmes to combat all aspects of addiction. Detox – A medically supervised ketamine detoxification programme is needed to help you safely manage any withdrawal symptoms after you stop using the drug.
Early research by the Philip Seeman group found ketamine to be a D2 partial agonist with a potency similar to that of its NMDA receptor antagonism. Collectively, these findings shed doubt on the involvement of monoamine reuptake inhibition in the effects of ketamine in humans. 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). The S-(+) and R-(–) stereoisomers of ketamine bind to the dizocilpine site of the NMDA receptor with different affinities, the former showing approximately 3- to 4-fold greater affinity for the receptor than the latter. However, multiple other NMDA receptor antagonists, including memantine, lanicemine, rislenemdaz, rapastinel, and 4-chlorokynurenine, have thus far failed to demonstrate significant effectiveness for depression.
One market report estimated that the ketamine industry was worth nearly $3.5 billion in 2023. With Musk’s new political power, his cognitive and psychological health is of concern not only to shareholders of his companies’ stocks but to all Americans. Frequent, heavy recreational use—say, several times a week—has been linked to cognitive effects that last beyond the high, including impaired memory, delusional thinking, superstitious beliefs, and a sense of specialness and importance. When Lemon asked if Musk ever abused ketamine, Musk replied, “I don’t think so. Musk has said he uses ketamine regularly, so for the past couple of years, public speculation has persisted about how much he takes, whether he’s currently high, or how it might affect his behavior.
