What is Ketamine?
Where does ketamine come from — and what is it? It’s a synthetic compound that can be classed as an arylcyclohexylamine — a designer or pharmaceutical drug. More specifically, Ketamine is a dissociative anesthetic. Like other dissociative drugs, it can create the feeling of being detached from one’s environment, which leads to a dissociated state, hallucinations, and a distorted experience of reality.
It works by blocking the N-methyl-D-aspartate (NMDA) receptors in the brain. This blocks or reduces pain signals sent to the brain, creating a state of anesthesia. It also affects other brain receptors, including opioid receptors.
Chemically, the drug is relatively simple. The formula for ketamine chloride, the most common form of medical ketamine, is C13H16CINO. It is formed by a cyclohexane ring that bonds to an aromatic phenyl ring and an amino group. In pure form, it appears as a white crystal powder and has a bitter taste.
Medical Origins of Ketamine
So, where does ketamine come from? Commonly informally referred to as ‘horse tranquilizer,’ ketamine does, in fact, have a history of use in a veterinary setting. It was developed in 1963 as a replacement for phencyclidine (a drug once used as a veterinary anesthetic, and briefly for humans too, that produced hallucinogenic and neurotoxic effects) and was used initially for veterinary purposes. In 1970 it was approved by the FDA after it was clinically shown that it created significantly lesser hallucinogenic effects than its predecessor, phencyclidine. It has since been used as an anesthetic in some medical settings and for veterinary purposes. It is an effective anesthetic in situations where a human patient’s cardiovascular system needs to remain stable or as an alternative to intravenous anesthesia. Ketamine is also widely used as an anesthetic for children, as it effectively controls pain without affecting a patient’s breathing.
Ketamine Production
Now you can answer the question, where does ketamine come from? It’s important to understand how it’s made. The main chemical ingredients used to produce the drug are cyclohexanone (a liquid), methylamine (gas), and chloroform (liquid). Each component and many other minor ingredients and catalysts are combined to produce it. The manipulation of these components to synthesize a high-quality final product is both complex and critical.
Today, pharmaceutical-grade ketamine is produced by several major companies worldwide, including Jannsen (a Johnson & Johnson subsidiary) and Allergan, and there is growing interest and research into its use in mental health.
Where Does Ketamine Come From: The Journey from Lab to Patient
It is a controlled substance, and therefore its production is tightly regulated. The entire lifecycle of ketamine, from raw material to the sale of the finished product, is heavily controlled. It is produced in specialized labs, where technicians and chemists work inside a carefully controlled environment to prevent contamination and produce a high-quality, safe final product. Once produced, the distribution and sale of the drug is also heavily scrutinized to try to prevent illegal ketamine production and use.
Illicit Production and Distribution
If it is produced pharmaceutically, where does ketamine come from when you buy it on the street? Despite strict regulations, it is both produced and distributed illegally, with it being manufactured in illegal laboratories. Illicit ketamine can be dangerous to make and use, as its creation requires the manipulation of hazardous chemicals, and those producing it often use rudimentary or substandard equipment and can also lack the comprehensive knowledge required for safe production. This creates a dangerous environment for the creator. Furthermore, Illicit ketamine will often not meet the strict quality standards of medical-grade ketamine and can cause harm or potential death to the user.
As well as illegal production, much of the illicit ketamine circulating in the U.S. is thought by the DEA to be stolen from legitimate sources such as veterinary clinics or smuggled into the country from Mexico.
The unregulated manufacturing and distribution of illicit ketamine can contribute to the individual and social issues of drug abuse and addiction, with widespread effects. We will discuss this more below.

Ketamine’s Role in Mental Health Treatment
Recent research into the effects of using it to treat mental health disorders has shown promising results, with ketamine contributing to significant improvements for patients suffering from a variety of mental health challenges, including depression, anxiety, and suicidality, often in cases where patients remain unresponsive to standard treatments. While it is now thought to be a promising breakthrough in this area, more research is needed to fully understand it’s long-term efficacy as a treatment for mental health. Today, ketamine therapy remains approved only in controlled medical settings.
Risks and Concerns Associated with Ketamine
While it is safe to use in a medical setting under the supervision of medical experts with experience prescribing and administering the drug, recreational use of it can be dangerous. Recreational use can involve higher doses, creating a stronger hallucinogenic or dissociative experience and ketamine side effects. Illicit ketamine may also contain other dangerous substances added during production.
It is a known addictive substance that can cause psychological dependence, leading to significant physical, mental, and social challenges. There are neurological risks associated with ketamine abuse, such as cognitive impairment, anxiety, depression, and reduced motivation, as well as physical dangers, including urinary tract issues and an increased risk of cardiovascular problems.
Treatment for Ketamine Abuse
If you think someone you know is struggling with ketamine abuse, here are some signs to look out for:
- Behavioral changes, erratic or unusual behavior, and detachment from reality.
- Severe mood swings.
- Dilated pupils, slurred speech, and impaired coordination.
- Memory loss and difficulties with concentration.
- Neglecting responsibilities like work, study, or parenting.
- Financial issues, such as someone spending all of their money on the drug, going into debt, or engaging in criminal activity to obtain the drug.
While ketamine dependence is a serious issue, the good news is that help is available. There are various treatment options, including in-patient programs, therapy and counseling, and supportive holistic therapies for addiction like meditation and yoga.

Frequently Asked Questions
What is the origin of ketamine?
Ketamine was first synthesized in 1962 by American chemist Calvin Stevens while working for Parke-Davis pharmaceutical company. It was developed as a safer alternative to phencyclidine (PCP), which had been used as an anesthetic but caused severe hallucinations and psychosis during recovery. Ketamine received FDA approval in 1970 and was widely used during the Vietnam War as a battlefield anesthetic due to its rapid onset, relative cardiovascular safety, and short duration of action. Its synthetic origin means it has no natural source; all ketamine, legitimate or illicit, is produced through chemical manufacturing.
How is ketamine made?
Ketamine is produced entirely through chemical synthesis in pharmaceutical or illicit laboratories. The manufacturing process involves several steps of organic chemistry starting from compounds like 2-bromocyclohexanone and 2-chlorophenylglycine, producing the final ketamine hydrochloride salt used clinically. Pharmaceutical-grade ketamine is manufactured in licensed facilities under strict quality controls. Illicit ketamine used recreationally is typically either diverted from legitimate pharmaceutical supplies or manufactured in clandestine laboratories primarily in South and Southeast Asia. Because it has no plant or animal source, all ketamine enters the market through either legal pharmaceutical channels or illicit production.
Is ketamine legal in the US?
Ketamine is a Schedule III controlled substance in the United States, meaning it has accepted medical use but also abuse potential. Possession of ketamine without a valid prescription is a federal offense. Medical use of ketamine for anesthesia and, more recently, for treatment-resistant depression through FDA-approved esketamine (Spravato) nasal spray is legal when administered by licensed medical providers. Several states have also seen the emergence of ketamine infusion clinics for off-label IV administration for depression. Recreationally obtained ketamine, most commonly diverted from pharmaceutical supplies, is illegal to possess.
What is ketamine prescribed for?
Ketamine has several legitimate medical uses. It is used as a general anesthetic in surgical settings, particularly useful for procedures requiring short-duration anesthesia and in settings where respiratory monitoring is limited, because it maintains airway reflexes better than many other anesthetic agents. Since 2019, esketamine (Spravato), a nasal spray form of the S-enantiomer of ketamine, has been FDA-approved for treatment-resistant depression and major depressive disorder with active suicidal ideation. Off-label intravenous ketamine infusions are also used in pain management clinics and some psychiatric settings for depression.
How does ketamine affect the brain?
Ketamine primarily works by blocking NMDA (N-methyl-D-aspartate) glutamate receptors in the brain, which disrupts normal glutamate signaling and produces its characteristic dissociative and anesthetic effects. At sub-anesthetic doses, this NMDA blockade creates altered perceptions, detachment from reality, and the psychedelic-like experiences sought by recreational users. At higher doses, it produces the k-hole, a state of profound dissociation approaching unconsciousness. Ketamine also stimulates AMPA glutamate receptors, which may explain its rapid antidepressant effects. It increases synaptogenesis (formation of new synaptic connections) in the prefrontal cortex, which is distinct from how traditional antidepressants work.
Is ketamine addictive?
Ketamine can produce psychological dependence with regular use, though it lacks the intense physical withdrawal syndrome associated with opioids or alcohol. Regular users describe strong cravings for the dissociative experience and difficulty functioning without it. Tolerance develops with frequent use, driving escalating doses. Heavy, chronic ketamine use causes ketamine cystitis, a potentially irreversible destruction of the bladder lining causing severe pain and urinary urgency, which is a particularly damaging and distinctive long-term consequence. Cognitive impairment, especially in memory and executive function, also accumulates with chronic heavy use. Resurgence Behavioral Health treats ketamine use disorder as part of our comprehensive program.
What does ketamine abuse look like?
Ketamine abuse typically involves using the drug recreationally for its dissociative and hallucinogenic effects, often at parties or raves. Signs include unexplained periods of profound dissociation or appearing "k-holed" (completely unresponsive and disconnected), finding ketamine paraphernalia, financial drain without explanation, recurring urinary tract symptoms (a distinctive consequence of heavy ketamine use called ketamine cystitis), and bladder problems requiring medical attention. Chronic abuse also produces cognitive impairment and memory problems.
What are the signs of ketamine overdose?
Signs of ketamine overdose include severe confusion and disorientation, inability to move or respond (the "k-hole"), respiratory depression, vomiting while in a dissociated state (creating aspiration risk), very high blood pressure, seizures at very high doses, and cardiovascular effects. Because ketamine is a dissociative anesthetic, overdose produces a state that is genuinely dangerous due to loss of protective reflexes rather than simply unconsciousness. Anyone experiencing these symptoms needs emergency medical attention.
Can ketamine be used to treat depression?
Yes, ketamine has been approved by the FDA in its esketamine (Spravato) nasal spray form for treatment-resistant depression. Intravenous ketamine infusions are also used off-label in clinical settings for rapid antidepressant effects, often showing results within hours to days in people who have not responded to other treatments. The antidepressant mechanism involves NMDA receptor modulation and synaptic plasticity in ways different from traditional antidepressants. Resurgence Behavioral Health incorporates evidence-based treatments for co-occurring depression and addiction.
What is dissociative drug abuse?
Dissociative drug abuse involves compulsive use of substances that produce a disconnected, trance-like state by disrupting the glutamate NMDA receptor system. Common dissociatives include ketamine, PCP (phencyclidine), and DXM (dextromethorphan found in cough syrups). Regular use can cause persistent cognitive impairment, dissociative episodes outside of drug use, depression, bladder damage (ketamine specifically), and psychological dependence. Treatment focuses on addressing underlying mental health conditions that the dissociation may be medicating.
