Signs of Ketamine Use: What Families Should Look For Before It Gets Worse
Many families start to worry because of small things. A son or daughter seems spaced out more often, their memory is getting worse, they get nosebleeds easily, they go to the bathroom unusually often, or there is white powder and a rolled-up banknote in their room. Yet it is hard to know whether this is something to worry about, because the signs of ketamine use, often called “K” or “Special K”, are easily overlooked or mistaken for tiredness and stress.
Ketamine is an anesthetic used in medicine. When it is misused, especially by snorting it at parties or nightclubs, use can grow into a daily habit that is hard to stop, with harm to the brain, mental health, and the bladder. Recognizing the signs early helps families step in before the damage becomes serious.
What Does Ketamine Look Like, and How Is It Used?
Ketamine is an anesthetic that produces a trance-like, detached state known as dissociation, and it is classed as a hallucinogen. It is a controlled substance under Thai law. Signs families can look out for include:
- Common names: K, ketamine, Special K, Kit Kat, “ya K” in Thai
- Appearance: white powder or small crystals, often in small zip-lock bags, or a clear liquid in a small bottle
- How it is used: snorted through the nose (the most common method), mixed into drinks, or injected
- Paraphernalia often found: rolled-up banknotes or straws, plastic cards with powder residue, small plates or mirrors with white residue, and small empty zip-lock bags
Note that the “K-pods” in recent news are mostly not ketamine but a different substance called etomidate. Learn more in K-Pods Are Not Ketamine but Etomidate.
Signs of Someone High on Ketamine
Ketamine acts quickly, especially when snorted. Signs you may see during use include:
- Seeming spaced out, poor concentration, slow or incoherent speech
- A dreamlike, detached look and slow responses
- Unsteady walking, loss of balance, difficulty moving, or sitting still unable to move
- Hallucinations or a distorted sense of time and surroundings
- Memory gaps about what happened
Take the person to hospital immediately if they cannot be woken, lose consciousness, breathe slowly or shallowly, have a seizure, or have used ketamine together with alcohol or other sedatives, as this can be life-threatening.
Signs of Regular Ketamine Use
As ketamine use becomes more frequent or daily, the signs families notice become clearer.
Physical Signs
- Urinary problems: frequent urination, pain or burning when urinating, difficulty holding urine, lower abdominal pain, and sometimes blood in the urine. These are symptoms of ketamine-induced cystitis. Read more in Ketamine and Cystitis.
- Nose: frequent nosebleeds, reduced sense of smell, and a frequently blocked nose from snorting
- Stomach: frequent stomach pain or cramps, especially when not using
Changes in Thinking, Mood, and Behavior
- Worsening memory, forgetfulness, slower thinking, and declining performance at work or school
- Irritability, mood swings, or low mood, especially when trying to cut down or stop
- Some people become suspicious, speak incoherently, or have a strange look in their eyes, which can be a sign of emerging psychotic symptoms
- Spending unusual amounts of money, going out at night often, a new group of friends, and more secrecy or lying
A common pattern starts with using ketamine at nightclubs with friends two or three times a week, then buying it to use at home, using more and more often until it becomes daily. When the person tries to cut down, they feel irritable and have stomach cramps, so they keep using. This cycle is a sign of addiction that needs treatment.
Can a Urine Test Detect Ketamine?
Yes. Urine drug tests can detect ketamine. Day One Rehabilitation Center tests urine for 10 substances, including ketamine. How long it can be detected depends on the amount, how often it is used, and each person’s body. Learn more about how long drugs can be detected in urine.
However, a test result is only part of the picture. Patterns of use and their impact on daily life tell you more. If you suspect a loved one is using ketamine, starting a conversation out of concern usually works better than trying to catch them out.
What Families Should Do When They Notice the Signs
- Stay calm before talking. Choose a time when they are not high or irritable. Describe what you have noticed with care, for example “I’ve noticed you’re going to the bathroom a lot and seem exhausted, and I’m worried,” rather than making accusations. Read more on how to talk to someone about getting treatment.
- Make an agreement and suggest an assessment. Suggest seeing a doctor about urinary problems and memory, which the person is often already worried about. This can be a good starting point.
- If this does not work, for example they keep using, break the agreement, or start showing emotional or psychotic symptoms, it may be necessary to bring them for treatment even without their consent, to help them before the harm to the brain and bladder becomes too severe to reverse.
Treating ketamine addiction means caring for stopping use, emotional and psychotic symptoms, urinary problems, and relapse prevention at the same time. See ketamine symptoms, effects, and treatment and how to quit ketamine safely.
