Ketamine Addiction
Ketamine addiction can involve cravings and continued use despite harm. Care can address bladder symptoms, memory concerns and the pattern of use together.
Battling addiction & ready for help?
When Ketamine Becomes Hard to Control
Ketamine can be addictive. Using more than you intended, finding it difficult to cut back, or continuing despite pain or other problems are reasons to ask for help.[1][2] Treatment can address the pattern of use, physical symptoms and mental health together.[1][3]
You may have started using ketamine for its effects or to cope with distress. What matters now is how it is affecting your life and what support would help you make a change. You do not need to decide whether “addiction” is the right word before arranging an assessment.[1][3]
Call 911 now if someone collapses, has a seizure, has trouble breathing or cannot be awakened. Do not assume severe impairment is just a K-hole.[4][5]
- Loss of control over ketamine use and continued use despite harm can signal a problem. An assessment looks at the pattern of use and its effects on your life.[1][2]
- Care can address physical symptoms and ketamine use together. Bladder pain, abdominal pain and memory concerns deserve attention alongside cravings or difficulty stopping.[1][3][6]
- Support for ketamine addiction can include medical care, counseling and follow-up. The setting and plan should match your needs. Research has not established a standard medicine or gradual dose-reduction plan for ketamine use disorder.[3][7]
Is Your Ketamine Use Becoming a Problem?
The National Institute on Drug Abuse describes warning signs such as using more than intended, spending substantial time getting or using ketamine, using it in dangerous situations and continuing despite knowing it is causing problems.[2] Look at what is changing, rather than comparing yourself with someone who uses more.
For example, a reason to seek assessment might be:
- You planned to use less, but use is taking up more of your time.
- You keep using even though you have noticed bladder pain, memory problems or other harm.
- You are using in situations where impairment puts you or someone else at risk.
These are reasons to seek help, not a self-diagnosis checklist.[1][2] You can ask for an assessment without waiting for every warning sign.
Problematic use is a broad description, not a diagnosis. It can describe use that is difficult to control or continues alongside physical or psychological harm. Ketamine use disorder refers to a clinical pattern of ketamine-related impairment or distress. Assessment considers the overall pattern rather than one episode, tolerance alone, or the mere fact of having used ketamine.[1][8]
Prescribed ketamine treatment is not automatically addiction. Tell your prescriber about cravings, taking more than planned or new symptoms. Tolerance means needing more for an effect previously achieved with less. Physical dependence means the body has adapted and may react when use stops. Addiction concerns a harmful pattern of use. Both deserve a clear discussion.[2][9]
How Can You Start Getting Help or Stopping?
Start with the concern that is making daily life harder. A primary care clinician, your current prescriber or a substance-use treatment service can be a starting point. Ask whether they can assess ketamine use and physical symptoms together, or coordinate the care you need.[1][3]
Describe What Is Happening
You could say: “I am using ketamine more often than I want to, and I need help making a plan.” Mention bladder or abdominal pain, mood changes, memory problems or symptoms when you try to cut back. These details can help focus the appointment.[1][7]
Write down what you can about how often you use, approximately how much, how you take it and any alcohol, other drugs or medicines. Include whether it was prescribed and what happens when you use less. An approximate history is more useful than delaying because you cannot remember everything.[1][7][9]
Ask for a Plan You Can Follow
Ask who will assess your physical symptoms, what support is available for cravings or distress, and whom to contact if symptoms worsen. Clarify the next appointment and how referrals will happen. If there is a wait, ask what help is available in the meantime.[1][3]
A taper means gradually reducing a dose. Ketamine research has not established one stopping or taper schedule for everyone. Discuss frequent or heavy use, other substances and mental health symptoms with a clinician rather than copying a schedule from another person.[7][9]
If ketamine or esketamine, a related medicine, is prescribed, discuss changes with the treating clinician. If you are unsure about stopping, you can still ask for care for symptoms and talk through your goals. Counseling can help you explore mixed feelings about change.[9][10]
What Does Treatment for Ketamine Addiction Involve?
Treatment for problematic ketamine use can combine medical assessment, support for changing use and care for mental health concerns. The practical question is what help you need now, and which service can provide or coordinate it.[1][3][7]
Medical Assessment and Physical Care
A clinician can ask what happens during use and when you cut back, assess urinary or abdominal symptoms, and discuss memory, mood or losing touch with reality. Ask how physical and mental health care will be coordinated.[1][6][7]
You can also explain what ketamine has been doing for you: for example, seeking detachment, relaxation, or relief from distress. These motivations were reported in the patient survey. Discussing them can make your goals clearer without assuming that self-medication is effective or that everyone uses for the same reason.[1]
Counseling, Cravings and Daily Life
Counseling can help you understand situations connected with use, practice coping skills and work through reasons for change. Cognitive behavioral therapy (CBT) focuses on patterns and skills. Motivational interviewing explores your own goals and mixed feelings. These are general substance-use approaches, while ketamine-specific counseling research remains limited.[7][10][11]
For example, a session might look at an evening when you wanted to use: what happened beforehand, what you hoped ketamine would do, and what other response or support you could try.[10][11]
Tell the team if pain, poor sleep, depression or anxiety is making change harder. Addressing the pattern of use while leaving important symptoms untreated may miss part of what you need help with.[1][3]
How Do Outpatient, Residential, and Inpatient Ketamine Care Differ?
Outpatient care means attending appointments and leaving the same day. Intensive outpatient or partial hospitalization programs provide more coordinated care, which can include individual appointments, groups, and coping skills. These are general substance-use care settings to discuss with a clinician, not a claim that one setting has proven superior for ketamine use disorder.[3][7]
Residential care means living at a treatment program. Inpatient care means staying overnight at a hospital or treatment program, usually when around-the-clock care is needed. The setting should reflect the person’s assessed needs. Not everyone with problematic ketamine use needs hospitalization. Ask what physical and mental health care a program provides, how it coordinates follow-up, and what it costs.[3]
What Role Can Medicines Play?
Clinicians may consider medicines for particular symptoms, but there is no established medication plan specifically for ketamine use disorder. The available studies are small or uncontrolled and provide very low-quality evidence.[7][8] Ask what a medicine is intended to treat, what side effects to watch for and who will review it.
Limited medication research does not mean there is no help available. Medical care, counseling and support for day-to-day change can address different needs. Ask the service how those parts of your care will work together.[1][3]
Choosing a Service That Fits Your Needs
In the international survey, affordability was the most frequently cited factor in choosing treatment. Among treatment-seeking respondents, only 36% reported satisfaction with care, and many perceived limited ketamine knowledge in services.[1]
In a University of Exeter news release, study coauthor Rebecca Harding, then a PhD candidate at University College London, said: “We need improved treatment programs, while raising awareness of ketamine use, to better support those seeking care.”[12]
A practical question is: “Can your team treat my physical symptoms and help with my ketamine use, or coordinate with someone who can?”
Before enrolling, confirm the total costs, insurance arrangements and follow-up. Ask how the service handles urinary symptoms and communication with your prescriber. The answers can help you judge whether the program fits the care you need.[1][3]
Tolerance, Physical Dependence, and Ketamine Use Disorder
These terms overlap but are not interchangeable. Tolerance concerns a changing drug response. Physical dependence concerns adaptation and symptoms when use stops or drops. A substance use disorder concerns a harmful pattern of use. Distinguishing them helps avoid labeling every medical exposure as addiction while taking loss of control and health consequences seriously.[8][9]
How Do Ketamine Tolerance and Physical Dependence Differ?
Tolerance means a reduced response after repeated exposure, so someone may use more to obtain an earlier effect. It has been reported with repeated ketamine use, particularly with high-dose patterns. Increasing exposure is therefore a reason to discuss the pattern of use, rather than assuming that a previously tolerated amount predicts future safety.[8]
Physical dependence means the body has adapted to repeated drug exposure, with signs or symptoms after abrupt stopping or a substantial reduction. These are called withdrawal symptoms. Dependence and compulsive use are different concerns. Spravato®’s label reports physical dependence with prolonged ketamine use and recommends monitoring for dependence when treatment is discontinued.[9]
Ketamine withdrawal reports particularly concern frequent, large-dose use over long periods, including use more than weekly. Reported symptoms after daily intake of large amounts include craving, fatigue, poor appetite, and anxiety. A clinical review describes sweating, shaking, and palpitations (a pounding or racing heartbeat) as generally less prominent than in alcohol or opioid dependence. This does not mean withdrawal is trivial or identical for everyone.[8][9]
No withdrawal symptoms were captured during the four weeks after esketamine treatment ended in the studies described by the Spravato label. That observation applies to the studied treatment conditions. It does not contradict withdrawal reports following frequent, heavy, long-term ketamine use.[9]
Longer-Term Ketamine Harms Worth Assessing
Research on chronic harms often involves persistent, frequent, or heavy nonmedical use, sometimes alongside other substances and mental health conditions. Those findings should not be applied automatically to every supervised medical exposure. At the same time, treatment supervision does not make new urinary, cognitive, or mental health symptoms unimportant.[6][8][9]
How Can Ketamine Affect the Bladder and Urinary Tract?
Long-term ketamine misuse is associated with cystitis, or bladder inflammation, and other lower urinary tract problems. Symptoms can include painful urination, urgency, frequent urination, and needing to urinate at night. Kidney dysfunction has also been described in chronic-use literature. These concerns provide reasons to discuss urinary symptoms with a healthcare professional.[6][9]
Spravato studies found more lower urinary tract symptoms among treated patients than people receiving an inactive comparison treatment (a placebo), but no esketamine-related interstitial cystitis (a form of bladder inflammation) was observed in studies including treatment for up to one year. This supports a distinction between studied treatment and chronic heavy misuse, not a claim of zero urinary risk.[9]
What Are Ketamine-Related Abdominal and Nasal Problems?
Abdominal pain associated with problematic ketamine use is sometimes called “K-cramps.” In an international online survey of adults with current or previous problematic use, reported symptoms included bladder problems in 60%, nasal problems in 60%, and K-cramps in 56%.[1] These were reports from a selected problematic-use population, not estimates for everyone exposed to ketamine.[1]
The survey included 274 eligible participants, with 179 completing all items. The number of respondents used to calculate each percentage therefore varied by question. Fifty-six percent reported not seeking treatment in response to the physical symptoms. The survey also described people increasing ketamine use in an effort to relieve pain, illustrating why pain and the pattern of use should be discussed together.[1]
How Can Ketamine Affect Memory and Mental Health?
Chronic ketamine use has been associated with memory impairment and differences in brain structure and communication between brain regions. Studies frequently involve heavy use, depression, or other substance exposure. These factors make it difficult to isolate ketamine’s contribution or predict an individual’s long-term course from a brain-imaging finding. Persistent memory or attention concerns are reasonable topics for clinical assessment.[6][8]
Anxiety, agitation, and psychotic symptoms, such as losing touch with reality, are described as possible acute effects, while craving, low mood, anxiety, and irritability were reported during periods without ketamine in the problematic-use survey.[1][6]
Some studies also describe depression, psychosis, or cognitive impairment persisting independently of withdrawal. Research has not consistently separated drug effects from pre-existing illness, other substances, or related circumstances. These symptoms may need care regardless of the final explanation.[1][6]
In the problematic-use survey, symptoms were chosen from a predefined list, including overlapping sleep items. The results identify experiences that matter to patients, but do not establish the same pattern of withdrawal symptoms for everyone or prove that every symptom was caused by stopping ketamine.[1]
Ketamine’s Immediate Effects and Safety Risks
Ketamine is a prescription anesthetic, a medicine used to prevent pain and awareness during procedures. It can cause dissociation, a feeling of detachment from the body or surroundings. Nonmedical use, supervised depression care, and anesthesia have different purposes and risks. A prescription or past medical use does not make new symptoms unimportant.[6][9][13]
Ketamine can alter perception, awareness, and pain. Dissociation may feel like detachment from your body or surroundings, with changes in balance, time, or the ability to respond normally. A K-hole is an informal name for intense detachment. It does not tell you whether someone is safe.[5][6][8]
Nonmedical use may be sought for dissociation, relaxation, self-medication, or psychedelic effects, changes in perception and experience. In a survey of adults with problematic use, reasons for beginning and continuing use varied, with dissociation and self-medication frequently reported.[1]
Reported short-term effects include dissociation, sleepiness, reduced sensation, anxiety, agitation, impaired attention, and verbal-memory problems. Executive function (the skills used to plan, control impulses, and make decisions) can also be impaired. Harmful effects involving the stomach or intestines and psychotic symptoms, such as losing touch with reality, have been reported. Impaired awareness during dissociation increases trauma risk.[6]
Polysubstance use means use of more than one substance. In the international problematic-use survey, more than one-quarter of participants reported another substance as their primary drug.[1] The authors noted that ketamine-related fatalities frequently occur in polysubstance contexts. Such findings do not identify one universal interaction or prove ketamine alone caused a reported death.[1]
Tell a treating professional about alcohol, nonprescribed drugs, and prescription medicines, not just ketamine. The Spravato label warns that combining it with alcohol, opioids, or benzodiazepines may increase sedation.[9]
Some interactions matter even in planned treatment: expert guidance highlights concerns with stimulant medicines and other medicines that can raise blood pressure, as well as medicines affecting ketamine’s processing in the body. Medication review is preferable to independently stopping or adding a drug.[14]
Severe impairment should not be dismissed as “just a K-hole.” Suspected contaminated injection also warrants urgent medical assessment because injection-related infection can become life-threatening.[13]
Do not drive while affected by ketamine. It can impair awareness, attention and coordination.[1][6]
When to Call for Emergency Help
Call 911 if someone cannot be awakened, has trouble breathing, collapses or has a seizure after taking ketamine or an unknown product. Dangerous agitation or confusion also needs emergency assessment when someone is at immediate risk.[4][5]
For possible poisoning without an immediate emergency, call Poison Help at 1-800-222-1222 in the United States. Do not wait for symptoms to appear.[4]
Stay with the person when safe, monitor breathing and give responders the product information you have. Follow emergency instructions about helping them breathe or giving CPR (cardiopulmonary resuscitation). Do not make them vomit or give an unconscious person anything by mouth.[4]
Medical Ketamine and Depression Treatment
Medical ketamine use is different from a ketamine use disorder. Injectable ketamine is approved by the U.S. Food and Drug Administration (FDA) for anesthesia. Spravato, a specific esketamine nasal spray, is approved for certain depressive conditions in adults and requires supervised administration.[9][13]
Racemic ketamine contains two mirror-image forms of the drug, including esketamine.[8] It is also used off-label for depression. That use does not change its FDA approval status.[9][13]
Off-label treatment means using an approved drug outside its approved labeling. Compounding means preparing a medicine for particular healthcare needs under applicable rules. Neither term means that the U.S. Food and Drug Administration (FDA) has approved that preparation or use. Nonmedical ketamine use is another distinct situation and can expose a person to uncertain contents and serious impairment.[9][13]
The comparison below separates products and treatment settings. On a narrow screen, scroll sideways to read both columns.
| Product or setting | What to know |
|---|---|
| Injectable ketamine | FDA-approved for anesthesia. Use for depression is off-label.[13] |
| Spravato nasal spray | Approved for adults with treatment-resistant depression, with or without an oral antidepressant. A separate indication covers depressive symptoms in adults with major depression and acute suicidal thoughts or behavior, with an oral antidepressant.[9] |
| Compounded ketamine | A compounded spray or lozenge is not the FDA-approved Spravato product. Ask exactly what is prescribed and how monitoring works.[13] |
| Nonmedical products | Contents may be uncertain. A familiar appearance or prior experience cannot establish safety.[2][13] |
Treatment-resistant depression means depression that has not responded adequately to other treatments. Spravato must be used in certified healthcare settings, with monitoring for at least two hours. It has not been shown to prevent suicide or reduce suicidal thoughts or behavior, and it does not replace hospitalization when needed.[9]
For suicidal thoughts or emotional distress in the United States, call or text 988 for support. Call 911 for immediate danger.[4][15]
Research supports short-term antidepressant benefit in selected patients, while longer-term evidence and the results for different formulations vary. A compounded lozenge or nasal spray is not automatically equivalent to Spravato or to ketamine used in a clinical trial. Discuss the exact product, expected benefits, monitoring, and follow-up with the prescriber.[14][16][17]
Before paying an online service, ask who prescribes the medicine, which pharmacy supplies it, and who responds to adverse effects or use outside the plan. Keep your treating clinician informed about other substances and any new urinary, cognitive, or mood symptoms.[9][13]
Why Do the Product and Setting Matter?
Ketamine acts partly by blocking N-methyl-D-aspartate (NMDA) receptors, parts of nerve cells that respond to the chemical messenger glutamate. Racemic ketamine contains two mirror-image molecules, including esketamine. Spravato contains esketamine, but a compounded ketamine spray or nonmedical powder is a different product with different oversight.[8][13]
What Can Research Tell Us About Ketamine Use?
Research helps explain patterns of use and where care needs to improve. The population being studied matters: a national survey, a survey of people already experiencing problems and a treatment study answer different questions.
How Common Is Nonmedical Ketamine Use?
A US trends study combined surveys with records of poisonings, deaths, pharmaceutical diversion and law-enforcement seizures. Diversion means a medicine moving outside authorized medical channels. Poisonings, diversion and seizures increased, while trends in reported use differed between populations.[6]
Using National Survey on Drug Use and Health data, the study estimated that past-year nonmedical ketamine use among US noninstitutionalized people aged 12 or older rose from 0.19% in 2021 to 0.34% in 2023.[6] These figures measure reported use, not ketamine use disorder.[6]
In a separate survey of 12th-grade students, past-year ketamine use declined from 2.49% in 2000 to 0.9% in 2023.[6] These ketamine statistics describe students, while the national estimate covers people aged 12 or older.[6]
The records could not consistently distinguish medical, nonmedical and illegally sourced ketamine. Surveys also underrepresented some people, including institutionalized or unhoused populations and students absent from school. Changes in methods, particularly around 2020, complicate longer-term comparisons.[6]
Among New York City nightclub attendees, a study cited in the review estimated past-year use at 7.4% in 2017 and 14.3% in 2024.[6] Nightclub studies also identified unknowing exposure, including ketamine in drugs sold as ecstasy.[6] These findings describe that setting, not national prevalence.
What Have Medication Studies Found?
A 2024 systematic review, a structured search and assessment of research, found 12 medication studies involving 368 participants: one controlled trial, two reviews of past patient records, and nine reports about individual patients.[7]
Two concerned intoxication, six withdrawal, and four craving or relapse prevention. All reported outcomes were descriptive, and the evidence was rated very low quality. No randomized medication trials, which assign participants to treatment groups by chance, were identified.[7]
Reports described benzodiazepines, medicines used in these medically managed reports for agitation or withdrawal, and haloperidol, a medicine reported particularly for acute psychotic symptoms. Individual case reports also described the medicines naltrexone, lamotrigine, and paliperidone palmitate plus bupropion for craving or relapse prevention. These are research leads, not established routine choices.[7]
The review found no published safety outcomes for those interventions. Only 102 of the 368 participants were female, and all individual case reports described men.[7][8] A mechanistic review reported no approved medication specifically for ketamine use disorder. These limitations rule out treating the medication list as a self-directed withdrawal plan.[7][8]
If You Are Worried About Someone Else’s Ketamine Use
Begin with an observation rather than a label. You could say, “You’ve mentioned bladder pain and using more often. Would you be willing to talk with someone about the pain?” Ask what help they would accept, such as finding a clinician, discussing costs, or preparing questions.[1]
For immediate danger involving inadequate breathing, severe sedation, or dangerous agitation or dissociation, call 911 rather than waiting to resolve the larger treatment question. Otherwise, the next step can be a focused medical, mental health, or addiction conversation. Addressing one concrete concern is a reasonable place to begin.[1][6][13]
Common Questions About Ketamine
What Does Ketamine Look Like and How Quickly Can It Act?
Ketamine may appear as a clear liquid or white to off-white powder. Nonmedical use can involve snorting, smoking, swallowing, or injection. Effects can begin within minutes. Swallowing it generally produces a slower onset. A brief onset or shorter hallucinatory experience should not be used to decide whether someone is safe.[5][6]
Can Ketamine Be Used to Facilitate Sexual Assault?
Yes. Ketamine can cause sedation, impaired awareness, and memory loss, and it has been used to facilitate sexual assault. If someone may have been drugged, seek prompt medical help. Call 911 for unconsciousness or breathing problems. The person harmed is not responsible for another person’s actions.[4][5]
Will Ketamine-Related Bladder Problems Resolve?
Chronic heavy use is associated with urinary disease. Bladder symptoms need an individual assessment. Ask for assessment of painful urination, urgency, frequency, or nighttime urination rather than assuming symptoms will resolve on their own or prove irreversible.[2][6][9]
Finding Help for Ketamine Concerns
For help locating substance-use services, contact the Substance Abuse and Mental Health Services Administration (SAMHSA) National Helpline at 1-800-662-HELP (4357). It provides free, confidential treatment referrals and information, not counseling. Ask prospective services about ketamine experience, medical complications, costs, and insurance.[1][18]
Choose one manageable next step: request an assessment, contact your prescriber or ask a trusted person to help you arrange an appointment. You can start with the symptom or change that worries you most, then build a plan for the other concerns.[1][3]
If you are worried about ketamine use, start by describing your pattern of use and symptoms to a healthcare professional. Explore AddictionHelp’s Treatment Center Directory → and ask about ketamine assessment and coordinated care.
For support working through your concerns, you can also explore online therapy options. Ask about substance-use experience and communication with your medical team.
For suicidal thoughts or emotional distress in the United States, call 988, text 988 or chat with the 988 Lifeline. Call 911 for an immediate life-threatening emergency.[4][15]
Frequently Asked Questions
Is Ketamine Addictive?
Yes. Regular ketamine use can become difficult to control and continue despite harm. Using more than intended, spending substantial time getting or using it, or using in dangerous situations are reasons to seek an assessment. Tolerance or physical dependence alone is not the same as addiction.[2][9]
Can Prescribed Ketamine Cause Dependence?
Ketamine has dependence and misuse potential, including when it began as a medical treatment. The Spravato label requires assessment and monitoring for misuse and dependence. Tell your prescriber about taking more than planned, cravings or new symptoms. Supervised treatment and frequent heavy nonmedical use have different evidence and risks.[9]
What Are Ketamine Withdrawal Symptoms?
Reports after frequent, heavy, long-term use include cravings, fatigue, poor appetite, anxiety and low mood. Symptoms and other health problems vary, and some reported symptoms may overlap with pre-existing conditions. There is no well-established ketamine-specific taper, or gradual dose reduction, based on strong trials. A clinician can help plan care for your symptoms and other substance use.[1][7][9]
What Should I Do If Someone Is in a K-Hole?
A K-hole describes intense detachment, not a reliable measure of safety. Call 911 if the person cannot be awakened, has trouble breathing, collapses or has a seizure. Stay with them when safe and follow emergency instructions. Do not give an unconscious person anything by mouth or make them vomit.[4][5]
Can Ketamine Damage the Bladder?
Chronic heavy use is associated with bladder inflammation and urinary problems. Painful or frequent urination, urgency and nighttime urination deserve medical assessment. Some urinary symptoms have also been reported during supervised esketamine treatment. Do not assume symptoms will go away on their own or that they must be permanent.[2][9]
What Treatment Helps with Ketamine Addiction?
Care can address physical symptoms, mental health and the pattern of use together. Medication research remains very limited, and there is no established medication plan specifically for ketamine use disorder. Ask about counseling, medical assessment and the appropriate level of care. The Substance Abuse and Mental Health Services Administration (SAMHSA) National Helpline at 1-800-662-4357 offers treatment referrals and information, not counseling.[3][7][18]
