Ketamine Signs, Symptoms, and Effects

Skip To Section

Abuse of ketamine can have fatal consequences and long-term negative effects. Since ketamine is a dissociative drug, it can warp reality, causing users to feel cut off from both their environment and themselves. This can frequently result in hallucinations. Ketamine has a reputation as a “club drug” since it is frequently abused by young adults and teens at dance clubs and raves, despite being a legal anesthetic for both humans and animals. Ketamine usage, however, has major negative effects, such as disorientation, memory loss, elevated heart rate, and in extreme situations, the possibility of permanent kidney and bladder damage.

Ketamine’s street names include:

  • Special K
  • Super K
  • Super Acid
  • Vitamin K
  • Purple
  • Kit Kat
  • Cat Valium
  • Jet K

Ketamine comes in a white or off-white powder or clear liquid. The powder is snorted or smoked, often in tobacco or marijuana cigarettes. In its liquid form, ketamine is either injected or mixed into drinks. Long-term ketamine use may impair your memory and cause depressive or delusional thinking. Ketamine is commonly taken with other substances. If used with high levels of alcohol or other depressants, it can cause respiratory distress or even death.

Many signs of ketamine addiction can be obvious, while others might be harder to notice. If you believe someone you know is abusing ketamine, it’s important to learn about the signs and symptoms.

Slang Terms for Ketamine Side Effects

There are a couple more things to keep in mind about the signs of Ketamine abuse. For example, there are several slang terms associated exclusively with experiences had during ketamine use, such as:

  • K-hole – An out-of-body, near-death experience, this experience can be terrifying for the user and can make them feel as if they are completely detached from their senses.
  • Baby food – A blissful and childlike experience
  • K-Land – A colorful and calm experience
  • God – Feeling as if the user has had a divine experience

If you have heard a loved one use these terms to describe an experience they had, they could be abusing ketamine.

Withdrawal Symptoms from Ketamine Addiction

The abuse of dissociative drugs, such as ketamine, can lead to dependency. This means your body becomes dependent on the substance and reacts negatively when the drug is no longer taken. If you experience symptoms once you are no longer taking ketamine, you could be experiencing withdrawal symptoms. Common withdrawal symptoms are:

  • Headaches
  • Sweating
  • Cravings for the drug
  • Shaking

Don’t Wait Too Long to Get Help

Although the long-term adverse effects of dissociative drug use are still being studied, there have been reports of physical, emotional, and mental symptoms documented after long-term abuse. Also, while it is rare, there have also been documented deaths associated with ketamine abuse. With that in mind, it’s important to pay attention to changes in behavior and address those changes with your loved ones.

Talking to a loved one about suspected ketamine abuse can feel scary and daunting, but approaching them with care and without judgment can go a long way. They may be defensive when discussing the addiction, but explaining your concern and being knowledgeable about options for help can be beneficial. Keep in mind that those struggling with their addiction often go to great lengths to hide it, and being faced with it can be extremely difficult. So while it can be a challenging conversation to have, it can also lead to your loved one getting the help they need. It can be comforting to know what to expect if you or your loved one decide to seek treatment for an addiction. When seeking treatment for addiction, the first step is usually detoxification or detox. This is the process of removing drugs from the body, and it should ideally be done while managing withdrawal symptoms under the supervision of medical professionals.

After the detox process, the recommended next step is individual mental health counseling. In counseling, individuals learn about triggers for their substance abuse. They then learn about healthy coping strategies to use when exposed to these triggers. They’ll learn other helpful tools as well, like how to build a support system and how to avoid high-risk situations in sobriety. There are many different treatment options available. The option that is right for you or your loved one depends on the severity of the ketamine addiction. You can learn more about the different options here:
