While ketamine is safe to use in controlled medical practice, it becomes hazardous if someone takes it for recreational use as it may result in potentially life-threatening adverse effects. Santamour believes the data provided to the public, including those trying to save people from dying from accidental overdoses, is incomplete and released months after the information is useful. The increase of xylazine present in those who died from drug overdoses does have people worried. “Smoking fentanyl has potential health benefits over injecting and may be protective against overdose, but substantial uncertainty exists,” the study says.

Given over 10 years of experience with ketamine as a researcher and physician, in this article I try to answer some basic questions prospective patients often have about ketamine/esketamine. In summary, studies show that ketamine infusions may reduce craving and promote recovery for people with alcohol, stimulant, and opioid use disorders. That the effects of ketamine on craving and substance last months across studies are especially exciting. For depression treatment, by contrast, effects usually only last a few weeks. Ketamine is not currently approved by FDA for the treatment of any substance use disorder. These insights into ketamine’s effects on brain circuits could guide future advances in managing mood disorders.

Ketamine hydrochloride, also known as Special K, Kit-Kat, or simply K, belongs to a class of drugs called dissociative anesthetics or hallucinogens. These drugs, which also include nitrous oxide and phencyclidine (PCP), separate perception from sensation. It can produce dissociative and hallucinogenic effects, which are collectively called a K-hole or K-holing. When taken at low doses, ketamine produces feelings of distortion of time, space, and mild hallucinations. People feel that they are becoming part of their surroundings (melting into their surroundings), become very happy, feel sociable, and often experience visual hallucinations. One of the things that makes this process so difficult is when the patient cannot participate or is resistant to authentically participating.
Ketamine Slang Terms
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. A form of ketamine known as esketamine nasal spray was approved by the FDA in 2019 under the name Spravato for use in treatment-resistant depression. IV-infused ketamine is an FDA-approved anesthetic for surgical and medical procedures.
Understanding Ketamine’s Use in Physical and Mental Health
- The “Meet Cute” star checked into rehab last summer after struggling with drug use and mental health issues.
- After overusing ketamine for an extended period of time, some experience ketamine cystitis—damage to the bladder that can lead to pain and frequent urination.
- 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 United States overall saw a 3 percent drop in overdose deaths in 2023, according to the U.S.
- In order for patients to have clear expectations of what they will experience, it should be thoroughly explained prior to the first ketamine session.
When the ketamine-induced spines were eliminated, the mice again showed depression-like behaviors. When done in a safe and supportive space, the patient can have a more beneficial experience (Gorman, I., Nielson, E., & Paleos, C., 2021). This experience can include soothing music, incorporate the connection to nature through plants, and provide the use of light.
Medical use dosage forms
Many clinical trials have barred people with substance use problems. At Stewart’s clinic, after the mind-altering part of the ketamine experience is over, a health provider sits and talks with the patient in a process called integration. Other clinics may recommend that patients continue their talk therapy elsewhere. Especially since the news media reported that ketamine played a significant role in the death of actor Matthew Perry, a lot of patients wonder if ketamine/esketamine is actually safe. The short answer is yes, when it’s done with the proper safeguards. The most important one is that ketamine/esketamine should be administered while the patient is in a clinic (as opposed to at home).
That’s how Ken Stewart, MD, says doctors began to realize that the drug had powerful effects against depression and suicidal thoughts. Jeff Winograd, who’s lived with depression for 25 years, says ketamine treatment saved his life. Another form of ketamine called R-ketamine is currently being studied for treatment-resistant depression. According to reviews from 2020 and 2021, ketamine is approved by the Food and Drug Administration (FDA) for use as a short-term injectable anesthetic in humans and animals for sedation. It works rapidly (within 10 to 30 seconds) when given intravenously for anesthesia.
However, some research has suggested that the IV-infused drug provides a faster response than the nasal spray. In the past, there was speculation that ketamine masked depression by making a person feel “high.” This theory has since been debunked. Ketamine doesn’t remain in the system very long, yet research shows that people treated with it feel relief in the days and weeks after they stop taking it. Though they’re far from perfect treatments, ketamine and esketamine mark a breakthrough for treatment-resistant depression.
One of the pearls of the field of pharmacoepidemiology is that it’s not just about safety or effectiveness, it’s about safety and effectiveness and the balance of these. Additionally, ketamine can cause you to be briefly confused after waking up from surgery. Most people do not remember the early or late phases of ketamine on thinking and memory and can’t recall having had hallucinations or confusion.
The initial dose for anesthesia induction is administered over several minutes. Ketamine is not a first line treatment for status epilepticus, and it is generally used when other treatments are contraindicated or when they have not effectively stopped a prolonged seizure. Giordano also warned against taking ketamine more than once in one sitting. People may feel tempted, since the effects wear off fairly https://sober-home.org/facts-about-moderate-drinking/ quickly, but the effects of multiple doses add up. Some people are selling a form of street ketamine mixed with cocaine called “Calvin Klein,” a combination Giordano specifically cautioned against. “There have been a couple of case reports when people have shown up in an emergency room when they’re highly dissociated and on a coke high, so they completely act out or they become very agitated,” he said.
Ketamine can have side effects, including changes in blood pressure. This drug may be contraindicated for you if your blood pressure is unstable. However, it’s still illegal to possess or sell ketamine outside of medical settings. By the spring of 2018, I’d tried most of the more common psychedelics, but ketamine seemed like a wild card.
Ketamine and esketamine are chemically very similar, but they’re two different drugs. Ketamine is only FDA-approved as an anesthetic, and is still widely used for anesthesia and acute pain in surgical, operative, and emergency trauma settings. Esketamine was brought to market around 2019 for the management of treatment-refractory depression [depression not responsive to standard treatment].
The London Clinic has been re-branded by a separate company called Klearwell. It offers ketamine-assisted therapy for conditions such as depression, post-traumatic stress disorder, anxiety, eating disorders, and drug and alcohol addiction. Esketamine (Spravato) was approved by the FDA in 2019 to treat TRD.
Over the past decade or so, legal ketamine clinics have popped up to treat depression, OCD, and other mental health conditions. “It has literally saved lives for people who were ready to give up all hope,” Masand said. The clinic provided treatment to adults who had “treatment resistant depression, anxiety, post-traumatic stress disorder, mental health problems and substance and alcohol dependency”. For the past 20 years, researchers at top scientific institutions and universities have researched the efficacy of ketamine in the treatment of mental health disorders and shown positive results. The best clinical evidence shows that patients should start treatment twice per week for 4 weeks.
This is not a complete list of side effects, and others may occur. Ketamine became an FDA-approved medicine on February 19, 1970, as a general anesthetic to be used as the sole anesthetic agent for diagnostic and surgical procedures that do not require skeletal muscle relaxation. https://sober-home.org/ It is also used for the induction of anesthesia prior to the administration of other general anesthetic agents and as a supplement to other anesthetic agents. When used for anesthesia, ketamine is given as an intravenous injection (IV) or as an intramuscular injection (IM).
Also, while you’re in a K-hole, people around you may be unable to tell if you’re in distress or need help. Using ketamine or entering a K-hole does come with risks, some of them serious. Healthline does not endorse using any illegal substances, and we recognize that abstaining from them is always the safest approach. However, we believe in providing accessible and accurate information to reduce the harm that can occur when using. American Addiction Centers (AAC) is committed to delivering original, truthful, accurate, unbiased, and medically current information.
Ketamine is an NMDA receptor antagonist, meaning it blocks the N-methyl-D-aspartate neurotransmitter in the brain. It was developed in the 1960s and used as a battlefield anesthetic in the Vietnam War, as well as clinically in health care settings. But the settings in which ketamine was developed and historically used were highly regulated and supervised inpatient health care facilities. After the death of actor Matthew Perry, ketamine—for decades used as a popular party drug—came into the public eye once more. According to the medical examiner, Perry, who had been undergoing “ketamine infusion therapy” for depression, had levels of the drug in his body in the range used for general anesthesia during surgery. There are potential short- and long-term negative health effects related to ketamine use.
It would stand to reason that the manufacturer would have an enormous incentive to identify and get FDA approval for other indications. PTSD, or possibly severe generalized anxiety disorder, might fit that bill. Overdose and adverse effects of illegal ketamine use include nervousness, chest pain, seizures, and respiratory depression. Prolonged or repeated use can lead to psychiatric issues, including psychosis and flashbacks. Ketamine is injected intravenously (IV) or intramuscularly (IM, in a muscle) when used for surgery.
