Ketamine Addiction: Signs, Effects & How to Get Help

By Gary Clinton·Cocaine & addiction specialist·Reviewed June 2026

Ketamine has moved from clubs into everyday use for a lot of professionals — partly because it feels controllable. It isn't. As a dissociative anaesthetic it detaches you from your body and surroundings, and regular use carries a serious, under-talked-about physical risk alongside a strong psychological pull.

What ketamine does to you

Ketamine numbs and dissociates — at higher doses tipping into the disorienting "k-hole." Because it doesn't feel like a classic addiction, people convince themselves they're in control while use creeps up and tolerance climbs fast, pushing doses higher and higher.

Effects — including the bladder risk

Short term: dissociation, confusion, nausea, and impaired coordination (dangerous around water, heights or driving). Long term: the big one people don't hear about — ketamine bladder (ulcerative cystitis): severe, sometimes irreversible bladder damage causing intense pain and urinary problems, even in relatively young users. Memory and mood also suffer with heavy use.

Signs of ketamine addiction

Withdrawal and what to expect

Ketamine withdrawal is mainly psychological — strong cravings, low mood, anxiety and fatigue — though heavy users can feel physically rough too. The cravings ease as your brain rebalances, and each one you ride out makes the next weaker.

How to get help

Whatever the substance, the way out is similar: an honest look at where you actually are, then a plan built around your triggers and your life. If ketamine has stopped being a choice, don't wait for the bladder pain to make the decision for you. Start with the assessment below, or book a confidential chat.

60-second check-in

Quick check: where are you with it?

Five honest questions. Nothing is saved or sent — your result appears only on your screen.

1. Do you use more than you planned to, or carry on longer than you meant to?

2. Have you tried to cut down or stop and found you couldn't?

3. Does it take up a lot of your time, money or headspace?

4. Has it caused problems with work, money or people close to you — and you carried on anyway?

5. Do you need more for the same effect, or feel low, flat or anxious when you stop?
