It usually starts somewhere ordinary. An after-party in a flat in Observatory, a doof out in the bushveld, a friend’s birthday where someone produces a small bag and says it’s “lighter” than everything else going around. Ketamine has quietly become part of the soundtrack to going out in South Africa, especially for people in their late teens and twenties. It rarely arrives with a warning. More often it arrives with a shrug and a reassurance that it is nothing serious.
That reassurance is the problem. Ketamine is a powerful dissociative anaesthetic, the same drug used to sedate patients and animals in theatre, and the line between a casual weekend habit and something far harder to control is thinner than most young users realise. This is written for the people who use it, and for the parents, partners and friends who can see something shifting and do not quite know what they are looking at.
How ketamine found its way into the party scene
Ketamine is not new, but its place in nightlife has grown. It sells itself on a few promises that sound appealing in a crowded room at 3am: a short high, a dreamy sense of distance from everything, and a reputation for a gentler comeback than stimulants like cocaine or tik. The American National Institute on Drug Abuse classes it among the psychedelic and dissociative drugs, and describes how it can distort the way a person perceives sights and sounds, with heavier doses producing an “extreme detachment from their body and reality” that users call being in a k-hole.
In South Africa that detachment is exactly the selling point. Ketamine is among the substances most commonly turning up in the local club and festival scene, alongside MDMA, tik and LSD, and it is often marketed as something that enhances the music and the dancing rather than a drug in its own right. Because it does not carry the same jittery, wired reputation as stimulants, people tell themselves it is the safer choice. The pharmacology does not agree.
The “clean drug” myth
A lot of the appeal rests on the idea that ketamine is somehow cleaner or more controllable than other party drugs. Friends who have used it a few times without an obvious crisis become living proof in their social circle that it is fine. When nobody around you seems to be getting hurt, the risk feels theoretical. That shared confidence is how occasional use slides into regular use without anyone deciding it should.
The reality is that what gets sold as ketamine on the street is unregulated. There is no quality control, doses are eyeballed, and powders are frequently cut or mixed with other substances. Combining it with alcohol or other depressants raises the danger considerably, because ketamine can slow breathing to a dangerous degree on its own.
Why young people reach for it
Curiosity and belonging do most of the heavy lifting. Young people often try ketamine because it is simply there, passed around a group, and turning it down can feel like opting out of the moment. The promise of an experience that is different from the usual stimulant rush, with what is wrongly assumed to be a softer hangover, makes it an easy yes.
Cost plays a part too. In some areas ketamine works out cheaper per dose than other party drugs, which matters to students and young workers stretching a limited budget. A vial or bag gets shared around, and what was meant to be one person’s experiment becomes several people’s, repeated across more weekends than anyone intended.
There is also a quieter, heavier reason worth naming. Ketamine’s dissociation, that floaty sense of being lifted out of yourself, can be a way of escaping anxiety, low mood or stress rather than chasing a good time. When a substance becomes the thing that switches off difficult feelings, the relationship with it changes fast. Understanding the difference between using to celebrate and using to cope is one of the clearest early warning signs for a family to watch for.
The physical risks people underestimate
What ketamine does to the bladder
The damage that surprises people most is to the urinary system. Frequent ketamine use is strongly linked to a condition called ketamine-induced cystitis, which the NIDA describes as a treatable but potentially serious form of ketamine-induced uropathy. A peer-reviewed review in Health Psychology Research found that regular use raises the risk of cystitis symptoms roughly three to four times, with painful and frequent urination, urgency, and sometimes blood in the urine.
This is not a problem reserved for older, long-term users. South African clinicians have reported people under the age of 25 with such severe bladder damage that surgery, including bladder removal, became necessary. The same research notes that advanced cases can involve scarring of the bladder wall, blockages affecting the kidneys, and in serious cases chronic kidney failure. The encouraging part is that stopping ketamine is usually associated with improvement, which is one of the strongest reasons to act early rather than wait.
In the moment
Even on a single night, ketamine can cause loss of balance, slurred speech and confusion. That dreamy detachment becomes dangerous in a crowded venue, near water, or anywhere a person might fall or wander off. The American research also flags respiratory depression, dangerously slow and shallow breathing, as a real risk of unsupervised use, and that risk climbs sharply when ketamine is mixed with alcohol.
The mental side, and how dependence creeps in
The comedown is where many people first feel the cost. As ketamine leaves the system, anxiety, low mood and a hollow flatness can settle in. For some, the obvious fix is more ketamine, and that loop of relief and crash is the shape that dependence often takes. NIDA notes that laboratory studies show ketamine can cause brain changes typical of a drug with addictive potential, and that people develop tolerance and keep using despite knowing it is causing problems.
Tolerance builds quickly. Needing more to reach the same place pushes consumption higher, which in turn raises the risk to the bladder and to memory and concentration. Heavy long-term use has been linked to memory difficulties, depression, anxiety and, in some cases, psychosis. When social life starts organising itself around sourcing and using, when interests narrow and weekends blur, the line into addiction has usually already been crossed.
It is also common for ketamine misuse to sit alongside an underlying mental health condition, each one feeding the other. Treating only the substance while ignoring the depression or anxiety beneath it rarely holds, which is why dual diagnosis treatment matters so much in genuine recovery.
Where it sits legally in South Africa
Ketamine is a controlled medicine in South Africa, legitimately used in hospitals and veterinary practice, which means recreational possession and supply happen outside the law. Internationally there has been ongoing debate about tightening its scheduling, balanced against the fact that it remains an essential anaesthetic in much of the world, including parts of Sub-Saharan Africa where alternatives are scarce. For a young person, the practical point is simpler: buying, holding or sharing ketamine for recreational use carries real legal risk, even though the scene treats it casually.
How families can respond without pushing someone away
Fear and anger are understandable, but they tend to close the conversation rather than open it. Young people are far more likely to talk honestly when they are not bracing for a lecture. Calm, specific questions and a steady tone do more than ultimatums. If you are not sure how to begin, our advice on talking to your children about addiction is a practical place to start.
Watch for patterns rather than single incidents: recurring bladder or urinary complaints, money disappearing, a shrinking circle of interests, mood that swings hard after a weekend, or growing secrecy about where the weekends go. None of these on their own prove a problem, but together they are worth a gentle conversation.
When someone is reluctant to get help, the instinct to force the issue often backfires. There are calmer, more effective ways to encourage a loved one toward treatment, and knowing how to get someone to go to rehab can make the difference between a door closing and a door opening.
What recovery from ketamine actually looks like
Recovery is not about willpower alone, and it is not a single moment of stopping. For regular users, the early phase is usually a medically supervised detox to manage withdrawal symptoms such as anxiety, sweating and disturbed sleep safely. From there, the work moves to understanding why the drug took hold in the first place.
That is where structured therapy comes in. Individual counselling, group sessions and approaches like cognitive behavioural therapy help a person recognise their triggers and rebuild a life that does not revolve around the next weekend. Because ketamine use so often overlaps with anxiety, depression or unprocessed trauma, treating the whole person rather than only the habit gives recovery the best chance of lasting. Aftercare and ongoing support then carry that progress into everyday life, long after the inpatient stay ends.

Frequently Asked Questions
Is ketamine addictive?
It can be. NIDA reports that ketamine use can cause brain changes typical of a drug with addictive potential, that tolerance develops, and that people continue using despite knowing it is causing harm. Psychological dependence, where the comedown drives someone back to the drug, is common.
Can ketamine bladder damage be reversed?
Early bladder problems often improve once a person stops using, which is why acting sooner matters. In advanced cases, where the bladder wall has scarred or the kidneys are affected, the damage can be lasting and may need medical or surgical treatment. A doctor should assess any persistent urinary pain, urgency or blood in the urine.
Is it really more dangerous mixed with alcohol?
Yes. Ketamine can slow breathing on its own, and combining it with alcohol or other depressants increases that risk significantly. Mixing also raises the chance of accidents, since both substances affect coordination and judgement.
How do I know if my child’s use has become a problem?
Look for a shift from occasional, social use to something more frequent, secretive or solitary, alongside changes in mood, money, friendships and physical health such as urinary complaints. If using has become a way to cope rather than to socialise, that is a strong signal to seek professional advice.
