What is Ketamine?

Ketamine is a medication that has become a popular club drug over the past few decades. It’s used as an anesthesia and for relaxation or pain relief in medical settings. When used as a recreational drug, ketamine causes extreme hallucinations, disassociation, and tranquilizing effects. Recently it’s also been used as a controversial form of treatment for depression.

What is Ketamine

Ketamine is a beneficial medication in controlled, medical environments. Low doses ease pain and are a great alternative to stronger alternatives like opioids. It limits the need for painkillers which reduces the possibility of developing an addiction to prescription opioids.

Outside of prescribed medical use, though, ketamine use is dangerous and unpredictable. It can cause problematic mental and physical reactions and long-term use can lead to tolerance and eventual psychological addiction. Ketamine misuse alters the perception of sight and sound and it also decreases reaction time. It can even cause total disconnection from reality.

What is ketamine and how is it used? Why do people turn to this powerful substance for recreational use and when does it go too far? As the president of the American Society of Anesthesiologists, John Abenstein, MD, said, “Outside of the clinic, ketamine can cause tragedies, but in the right hands, it is a miracle.”

Who Discovered Ketamine and When?

Ketamine originated in Detroit, Michigan in the 1950s at the Parke-Davis and Company’s laboratories. Starting with cyclohexylamines, chemists were looking for the ‘ideal’ anesthetic medication that also relieved pain.

One chemist, Maddox, discovered the first process to synthesize phencyclidine (PCP) on March 26th, 1956. Two years later, on September 11th, 1958, pharmacologist Dr. Chen received Maddox’s compound. Along with Dr. Domino, Chen studied the effects of PCP on animals and later humans

After a few years of clinical studies the doctors realized phencyclidine wasn’t a reasonable option as a human anesthetic. Hallucinations were too severe and frequent even with supervised medical use. Research continued in an effort to discover a similar anaesthetic but with fewer PCP-like side effects.

A Parke-Davis chemical consultant, Dr. Calvin Lee Stevens, was the first to synthesize ketamine in 1962. He fused a ketone with an amine, thus its name ketamine. Ensuing studies showed that Stevens’ new compound effectively produced anaesthetic, analgesic, and cataleptic effects, without the undesirable hypnotic effects of PCP.

It was patented for use in both humans and animals in 1966 by Parke-Davis. Human ketamine trials continued through the 1960s and into the 1970s in countries around the world. Teams in Germany, Italy, Brazil, Japan, and the Netherlands contributed literature on their own research on the drug’s effects.

What is Ketamine Made Of?

Ketamine came from the need for a medication that anesthetized patients while also relieving pain. Though PCP was used for a brief time, the unpleasant hallucinations ensured its time as a medical solution was short-lived. Dr. Stevens decided that a series of phencyclidine derivatives would be a beneficial path to explore.

Ketamine is made of a ketone combined with an amine. In chemical forms, it’s noted as Cl-581, or 2-(O-chloro-phenyl)-2-methyl-amino cyclohexanone. This chemical combination created a potent anesthetic and analgesic but one with a much shorter duration and lower potency than its counterpart, PCP.

Chemistry of Ketamine

Ketamine is a derivative of cyclohexanone and is a chiral compound. It’s created from an intensive process involving numerous chemicals. The drug is used in medical settings as an anesthetic, sedative, and analgesic. It also has hallucinogenic properties when misused or abused.

Medical experts still don’t fully understand ketamine’s method of action on the nervous system. It is an effective anesthetic agent for many medical procedures but researchers are still trying to learn about its mode of action.

Recent research from the University of Pennsylvania, conducted by R.G. Eckenhoff, revealed that ketamine interacts with olfactory receptors in mice. They believe their discovery will lead to more anesthetics that target the olfactory receptors. Still, more research on the chemistry of ketamine needs to be conducted.

Is Ketamine Legal?

Ketamine is legal under supervision for specific medical procedures. It’s widely used as a veterinary anesthetic but it’s also a helpful part of human medicine, too. The World Health Organization has included ketamine in its Essential Medicine List since 1985.

Doctors can use it as an anesthetic or analgesic. Used properly, ketamine doesn’t slow breathing or decrease blood pressure, making it one of the most used anesthetics in the world. Overdoses under medical supervision are very rare. Ketamine is also beneficial for patients experiencing inflammation, mild to moderate asthma symptoms, and for depression.

While ketamine is legal for specific medical uses, recreational ketamine use is not legal. It should not be misused or abused and doing so puts users at risk of developing addiction. Its in the club and the rave scene makes it an illicit substance.

Ketamine is a controlled substance with the Drug Enforcement Administration. It’s classified as a Schedule III substance along with drugs like codeine and anabolic steroids. The DEA recognizes its abuse and dependence potential, but also acknowledges its benefits in medical settings.

Are Ketamine Infusions FDA Approved?

Ketamine infusions are a newer medical practice for patients with chronic pain and depression. It’s been in use as part of an alternative form of treatment in ketamine clinics for a few years. It was finally approved to treat depression by the US Food and Drug Administration last March.

FDA approved ketamine infusions to help individuals who don’t respond well to existing treatments. They specifically approved esketamine, the more active half of the ketamine chiral compound. Patients who seek ketamine treatment suffer from severe depression that ordinary modalities aren’t as effective at treating. It offers a fast-acting way to approach treatment.

There is a caveat to their approval, though; clinicians must administer the drug as a nasal spray in certified clinics. Patients must also be actively taking an antidepressant medication. They also need to have unsuccessfully tried two other types of antidepressants before receiving treatment with ketamine.

Can Ketamine Be Prescribed?

Ketamine cannot be prescribed for take-home use and picked up at a local pharmacy like other antidepressant medications. It’s only approved for use in certified ketamine clinics under the supervision of trained medical personnel. At-home ketamine use is considered illicit misuse and is not legal.

Ketamine clinics must undergo a risk evaluation and mitigation strategy program. They require proof of medical licensing as well as approval from the DEA to dispense a controlled substance. Requiring specialized certification ensures that ketamine treatment clinics provide safe and effective care for anyone seeking an alternative solution.

Prescribing ketamine for take-home use still comes with too high a potential for abuse, though. At-home ketamine use may be allowed at some point in the future but for now all patients must receive it via nasal administration at an approved clinic.

Ketamine Myths & Facts

There is plenty of misconception and misunderstanding surrounding ketamine. As alternative treatments using the drug grow in popularity, it’s crucial to understand some ketamine myths and facts. Not everything you hear about the substance is true.

Ketamine Myths and Facts

It’s difficult to know myth from fact with so much information available on the internet these days. The following breakdown of ketamine myths and facts should clear up some confusion surrounding the drug and its uses.

Ketamine Myths

Ketamine is not/is always addictive

Some believe ketamine is not addictive while others believe using it always leads to addiction. Both of these are myths. There’s no blanket statement that encompasses all use. Not everyone who uses ketamine becomes addicted, either immediately or in the long run. At the same time, developing ketamine addiction is very much possible.

It’s difficult to know whether someone will become addicted to ketamine. The drug affects people differently depending on a few factors. For example, those with addictive tendencies or a history of substance abuse are more likely to develop ketamine addiction. But to say it’s always addictive, or that it’s never addictive, is a myth.

Treatment with ketamine can solve any mental health issues

As ketamine infusion treatments become more popular, some may claim that it can solve any mental health issue. There are no studies or research to back up the claims that ketamine can treat any existing mental illness. Although there is some anecdotal evidence for certain individuals that doesn’t mean their experience applies to the masses.

The best way to treat mental health issues is at specialized treatment facilities. Programs focused on helping individuals manage and overcome their mental illness are proven effective in many studies. They incorporate multiple approaches to treatment rather than relying on a single modality or one-size-fits-all understanding.

Ketamine Facts

Ketamine is used for legitimate medical purposes

Despite its popularity among club-goers and ravers, ketamine is still in use for real medical procedures today. It’s not only used for recreational purposes. It has legitimate medical uses. Ketamine is a powerful anesthetic and analgesic, offering an alternative to opioid painkillers
while in medical treatment facilities.

Doctors use ketamine as an option when anesthetizing patients for surgical procedures to this day. Clinicians still find it beneficial to use despite its classification as a controlled substance. That doesn’t make it safe to use in a recreational setting, though.

Ketamine harms the bladder

Frequent ketamine use and abuse can cause damage to the bladder. The condition is called Ketamine Bladder Syndrome or Ketamine Cystitis. The drug well as its metabolites damage the epithelial cells in the bladder lining. These cells are responsible for containing urine but ongoing damage weakens the cells which causes urine to seep through.

Urine that seeps through the inner lining into the outer layers of the bladder causes deeper damage and worsening symptoms. These symptoms include needing to urinate more often, increasing the sense of urgency, and pain or pressure behind the pelvic bone. Continued use may cause incontinence, blood in urine, shrunken bladder capacity, or erectile dysfunction.

Ketamine Street Names

Ketamine’s popularity as a recreational drug has led to many different ketamine street names. In the past, the drug was frequently referred to as Special K. Today that name isn’t as common and people usually just call it “K”. Some other street names for ketamine include:

Ketamine Street Names
  • Kizzle
  • Kizz
  • Meow
  • Kitties
  • Kit Kat
  • Cat Valium
  • Super C
  • Green
  • Super Acid
  • Vitamin K

Medical Uses of Ketamine

Unlike many illicit, recreational substances, there are multiple legitimate medical uses of ketamine. Firstly, it’s known for its widespread use as a horse tranquilizer in veterinary practice. It’s not only useful for equine patients, though. Ketamine also has multiple medical uses in human patients as well.

Medical Uses of Ketamine

It’s important to note that any treatments involving ketamine should only be used under professional medical supervision. Self-medicating with ketamine, or with any other type of substance, is dangerous and could result in serious long-term health consequences. Never take any drugs without the direct recommendation of your qualified medical physician.

These various medical uses of ketamine do show evidence of their efficacy in controlled environments. Recreational or self-determined use does not qualify as a legitimate treatment use. Nor should these uses be seen as benefits of use; ketamine as a tool for treatment is just that.

The serious effects of the medical uses of ketamine (ex. anesthetic, analgesic) should be all the more reason to avoid recreational use of the drug. It comes with some properties that could cause long-term problems. Ketamine should never be used outside of a clinical or medical environment under direct care and instruction.

Ketamine for Anesthesia

The most common medical use for ketamine is for anesthesia. High doses of ketamine render patients unconscious for the purpose of intense, invasive medical procedures. Ketamine for anesthesia is officially approved by the Food and Drug Administration. This is true for both ketamine on its own as well as combined with other anesthetic drugs.

Ketamine for Depression

Newer studies are considering the effectiveness of ketamine for depression. These studies look at controlled doses administered in supervised ketamine clinics. 

Ketamine for Pain

Another common use is ketamine for pain. The drug acts similar to other pain relievers without the more dangerous effects of respiratory depression or low blood pressure. This reduces the need for expensive patient-monitoring equipment, making it useful in situations like disaster relief or conflict zones. In fact, the World Health Organization placed it on its Essential Medicines List for this reason.

Ketamine for Seizures

The drug has both proconvulsant and anticonvulsant properties so using ketamine for seizures comes with significant risk. For example, some studies show that it led to seizures in some epileptic patients. It should only be used to treat seizures in those who have no predisposition to episodes. Only knowledgeable medical professionals should attempt to treat seizure patients using ketamine.

Ketamine for Sedation

Ketamine for sedation is incredibly effective, particularly in pediatric patients. Used at low doses, it functions as a fast-acting sedative. Results from one study reported that 30 children who were administered ketamine intravenously experienced sedation within 2 minutes. Another study revealed that 98% of patients, among a study of 431 children, experienced rapid sedation.

Recreational Use of Ketamine

In addition to its use in veterinary and some human medicine practices, the recreational use of ketamine is also common. It’s often associated with the rave and festival scene because of its hallucinogenic effects. As one article describes it, ketamine is a “triple-threat” because of its three main effects: sedative, stimulating, and psychedelic.

Recreational Use of Ketamine

People enjoy using it and say it amplifies their experience with and connection to the music. Ketamine isn’t only used within the music scene, though. It’s also growing in popularity among clubbing and other city-dwelling partiers. Some users mix ketamine with cocaine for an even more stimulating experience. The mix is usually referred to as revolutionary or Calvin Klein lines.

Some also partake in recreational use of ketamine because they experience what they describe as a spiritual high. Like other hallucinogenic drugs, ketamine alters the user’s perception of time and space and can cause dissociation.

How Does Ketamine Work?

Ketamine is an incredibly potent drug. There is a fine line between what some consider an enjoyable ketamine high and a dissociative experience that’s known as a “k-hole.” Where that line lies is different for everyone, too, depending on various factors.

How does Ketamine work

Although it has stimulating properties it’s not the same intense high as other stimulants like cocaine. While coke causes a jarring, almost anxiety-inducing high, ketamine comes with a more fluid, loose high in lower doses.

How exactly does ketamine work, though?

How Does Ketamine Affect the Brain

Ketamine isn’t as straightforward as other substances like opioids or stimulants. For example, opioids interact with opioid receptors throughout the body and cause relaxing, pain-relieving effects. The exact ways ketamine affects the brain are still somewhat unclear and require additional research on greater numbers of people.

Current research indicates that ketamine affects the brain in multiple ways. It doesn’t appear to target one single system. Instead, it interacts with many different body systems, such as opioid receptors, serotonin production, and the glutamate system.

This widespread understanding is backed by the numerous ways people use ketamine. It functions not only as an anesthetic but an analgesic and an antidepressant as well. The drug also has hallucinogenic, psychedelic properties in higher doses, too. More research needs to be done before scientists have a deeper understanding of how exactly ketamine affects the brain.

Dangers of Ketamine

There are many dangers of ketamine that result from use and abuse. As rates of ketamine abuse increase, the great risk that comes with use becomes more clear. There are significant short- and long-term effects that may come from irresponsible, illicit recreational use of the drug. What makes ketamine so dangerous?

Dangers of Ketamine

Why Can Ketamine Be Dangerous?

There are many reasons ketamine can be dangerous when used recreationally. Though it has legitimate reasons for use in medical conditions, recreational use is illegal and potentially harmful. Ketamine is also a highly potent drug. There is a thin line between a manageable high and taking too much which increases the dangers of use.

Ketamine is a dissociative drug that, like many other hallucinogenic drugs, can cause unpredictable effects. This is especially true for those who aren’t familiar with using psychedelic substances. People who aren’t used to these types of drugs may experience intense psychological reactions when using ketamine. Falling into a “k-hole” is a common term used when someone takes too much of the drug and experiences a dissociative episode.

Ketamine abuse also causes confusion and impaired judgment. These effects lead people to make riskier decisions that they wouldn’t likely make when not under the influence. Its analgesic properties may also cause people to lose consciousness. It’s also why ketamine is occasionally used as a date rape drug.

Memory lapses and memory loss are two more dangerous effects of ketamine. Someone may find themselves in a risky or harmful situation with little to no idea of how they arrived there. These are only some of the many dangerous effects of ketamine abuse.

Overdose of Ketamine

Someone can experience an overdose of ketamine. An overdose occurs when a person takes more of the drug than their body can process or handle. There is a high risk of overdose when someone uses ketamine because it is such a potent drug; they may feel fine one moment then push their body over the edge after taking another dose.

The signs of a ketamine overdose include:

  • Dissociation
  • Difficulties moving or complete inability to move
  • Increased heart rate
  • High body temperature
  • Seizure
  • Coma
  • Death

Someone in a “k-hole” is on the edge of experiencing an overdose. Their body is immobile but their mind is active, somewhat like being aware in a dream while not being able to move. These intense hallucinations and dissociation can cause extreme short- and long-term psychological reactions.

Ketamine overdose is especially dangerous and potentially lethal if the person doesn’t receive medical attention right away. Combining ketamine with other substances increases the risk of overdose. The more substances your body needs to process, the greater your chance of experiencing substance toxicity.

Is Ketamine Addictive?

The feelings of detached, euphoric bliss that ketamine causes can be addictive. The drug distorts the user’s perception of reality and allows them to escape, even for a moment. Some people abuse the drug regularly and develop tolerance over time which makes ketamine addictive. They need to use more to achieve the desired effect as time goes on.

Ketamine is a controlled substance with the DEA, meaning the administration recognizes the drug’s potential for misuse and addiction. It is a Schedule III substance alongside other drugs like codeine and anabolic steroids.

The line between abuse and addiction is a fine line, though. Not everyone who uses ketamine will become addicted. They may abuse the drug without ever developing a ketamine addiction. Still, any type of recreational use is dangerous and comes with an increased risk of developing a problem over time.

Can Ketamine Cause Withdrawal?

Drug withdrawal symptoms occur when someone experiences physical or psychological reactions after they stop using a substance. Their body develops tolerance and adapts to the presence of the substance over time. When the substance is no longer in their system, their body responds with these negative reactions called withdrawals.

Ketamine causes withdrawal in people who regularly misuse and abuse it. It doesn’t occur in those who participate in occasional recreational use. Tolerance develops over weeks, months, or years of regular use. Those who use it daily will experience ketamine withdrawal symptoms when they stop taking it.

Ketamine withdrawal symptoms include:

  • Anxiety
  • Depression
  • Loss of appetite
  • Restlessness
  • Fatigue
  • Tremors
  • Chills
  • Nightmares
  • Irregular heartbeat

Withdrawal symptoms from ketamine may be mild or severe depending on a few factors. The amount someone uses, whether they combine it with other drugs, and their overall health all play a role in the severity of their withdrawal symptoms.

How Do You Treat Ketamine Addiction?

Drug abuse changes brain chemistry to the point that a person eventually relies on those substances to function normally. After this point, trying to overcome ketamine addiction alone is difficult and potentially dangerous. Once someone is addicted, they’ll find it almost impossible to quit without help.

Ketamine addiction is a serious condition and trying to treat ketamine addiction shouldn’t be taken lightly. Some signs that someone might
be addicted to ketamine include:

  • Using more of the drug
  • Needing more of the drug to experience the desired effects
  • Hiding their increasing use from friends and family
  • Spending most of their time using or thinking about using ketamine
  • Spending the majority of their money on the drug
  • Suffering performance at school or work
  • Spending more unexplained time away from friends and family

Seeking professional medical assistance is the best way to treat ketamine addiction. Medical professionals can ensure the person doesn’t experience any life-threatening symptoms when coming off substances. They can reduce the effects of any possible withdrawal symptoms to reduce extreme discomfort. Clinicians also monitor the person’s overall physical health during the process.

Ketamine addiction does not have to be the end of the road, though. Help is available if you or someone you love is struggling with an addiction to ketamine.

Where Can You Treat Ketamine Addiction?

Some people try to treat ketamine addiction on their own without seeking medical advice. This puts both the user and the people around them at risk. You should always seek professional help for someone struggling with drug addiction to ensure their safety throughout the process.

Seeking Addiction Help
