What Are the Signs of Ketamine Use in Teens?

The best way to help your teen with ketamine use is to know what signs you need to look out for.

As a strong dissociative general anaesthetic, there are a range of ways it can affect a young person taking the drug, both in the short and long term. Keep reading for the signs of ketamine use in teens to look out for.

Short-Term Signs of Ketamine Use

It’s a common misconception that drugs can only affect your health with prolonged use. Ketamine can start to wreak havoc on the body and mind after just its first use.

Effects range from physical symptoms such as nausea to mental changes with brain fog or even hallucinations. Common signs of short-term ketamine use to be aware of include:

  • Fever
  • Body shakes
  • Nausea and vomiting
  • Dehydration
  • Excessive sweating
  • Confusion
  • Hallucinations
  • Hypotension
  • Brain fog
  • Breathing difficulties
  • Ketamine use can start to affect the bladder, causing issues with incontinence. As ketamine is used more and more, the damage becomes increasingly severe.

Long-Term Signs of Ketamine Use

Using ketamine for longer periods of time can have life-changing effects on the body and mind, including symptoms like:

  • Increased risk of UTIs
  • Agitation
  • Panic attacks
  • Difficulties with memory
  • Liver damage
  • Psychosis
  • Anxiety
  • Depression

One long-term sign of ketamine use currently on the rise is known as ‘ketamine bladder’. A debilitating condition, it causes the bladder to shrink, leading to severe issues with incontinence.

Other effects of the ketamine bladder include pelvic cramps, burning sensations when you pee, bladder ulcers, and blood clots.

Is Ketamine Dangerous for Teens?

Yes, recreational use of ketamine is dangerous for teens. While it’s dangerous for anyone to use the drug, it’s particularly damaging to teens, as they’re in their developmental years.

Studies show ketamine can affect the developing brain, leading to issues with memory, concentration, and judgment later in life. It’s common to experience blank spots when trying to recall conversations from the time they were high on the substance as well.

It’s not just neurological issues ketamine can cause, as it can also impact the body, too. The bladder, kidney, liver, and urinary tract are all at risk of severe damage from excessive use of ketamine, with ketamine bladder being a particular concern.

While not everyone becomes addicted to ketamine, as with any drug, you do risk addiction when taking it. In fact, data from the UK government shows over 5,000 people entered treatment for ketamine in 2024/25.

Why Do Teens Take Ketamine?

Updated government data shows that ketamine use within the 16 to 24-year-old age group has increased 230% from 2012/13 to 2023/14. When you know the dangers of the substance, it can be difficult to understand why there’s been such an uptick in its use.

Numerous factors are likely responsible, ranging from social and cultural trends to financial reasons. Some reasons that could explain the rise in ketamine use include:

  • Peer Pressure: Manchester Metropolitan University released data showing that young people who experience peer pressure are more likely to use drugs. Other factors include being bullied or struggling with their emotions.
  • Cheaper Costs: Generally, ketamine is a more affordable drug to buy than some others. Data from Drug Wise shows that a gram of ketamine costs between £20 and £40, while the same amount of cocaine can cost as much as £120.
  • Safe Perception: Ketamine is used in hospitals as a sedation and pain relief tool. As such, it could create a false idea that it’s safer than other drugs. Despite its use in medical settings, ketamine is still a dangerous drug for recreational use.

What Should I Do if My Teen is Taking Ketamine?

When you’re a parent, knowing what to do when your teen is taking ketamine can feel like an impossible task. However, there are steps you can take to ensure their safety.

First of all, try to remain as calm as possible as you go about this. We know that may be easier said than done, but approaching this with care is crucial for the right outcome.

  • Try Talking: Choose a calm moment in a space they feel comfortable in to help them feel safe to talk. Avoid making accusations, as they can cause them to feel judged. Try to listen without interrupting, focusing on their safety instead of punishment.
  • Speak to their GP: Getting medical intervention early on can help avoid physical health problems down the line or treat any that may already be present. Their GP will also be able to advise on the best course of action for addiction treatment.
  • Attend Support Groups: For both you and your teen, ketamine misuse can feel incredibly isolating. There are plenty of support groups available to meet others on their own journey – find a meeting near you with Narcotics Anonymous UK.

While not every teen using ketamine will face addiction, it’s important to get help as soon as possible if your teen is addicted to the substance.

If your teen has trouble breathing, seems confused, is hallucinating, or experiences chest pain after using ketamine, call 999 or take them to A&E.
