They may also be unable to move their body due to feeling completely detached from their body and surroundings (known as a K-Hole). The ‘high’ of ketamine may last for up to an hour but the effects of use may still be present some hours later. Ketamine increases heart rate and blood flow, relaxes airways and increases muscle tone. People who have been administered ketamine in surgery will appear awake (eyes remain open) but are in a dissociative state. Ketamine is often combined with other drugs, which can make the negative side effects of Ketamine even worse. Ketamine in its liquid form can be easily mixed into an alcoholic beverage or added to Marijuana joints.
No person with alcohol abuse disorder or alcohol intoxication should take ketamine, even in doctor-prescribed doses, as it can cause death. Both alcohol and ketamine are central nervous system depressants, so the combined effects are dangerous. Individuals who take ketamine recreationally report sensations, such as being separated from their body or a pleasant feeling of floating. Some people have an almost complete sensory detachment that they compare to a near-death experience. The drug is a Schedule III non-narcotic that the Food and Drug Administration (FDA) has approved for use only as a general anesthetic.
Ketamine Toxicity
Flashbacks to visual hallucinations have been reported after recreational ketamine use, but recurring symptoms are rare. People use ketamine to feel euphoric, out-of-body experiences and other effects of hallucinogens. The drug is sometimes used to facilitate sexual assault because it causes sedation and memory loss. Ketamine — also known as Special K — is a dissociative drug that makes people feel out of control or detached from reality.
These changes ultimately produce synaptic improvements such as structurally increased spine density at synaptic proteins (17). These effects may improve ability to learn new behaviors (18) and may be beneficial in the treatment of SUDs. Our overall objective is to provide a review of the recent literature on the efficacy of ketamine in the treatment of SUDs. Jovaiša et al. (23) conducted a randomized controlled trial in which participants were given either saline placebo infusion or 0.5 mg/kg/h of IV ketamine prior to rapid opiate antagonist induction under general anesthesia. Their results showed that ketamine could suppress physiologic response to opiate withdrawal.
What are the signs and symptoms of ketamine addiction?
For example, the United States, which accounts for 25% of global overdose mortality, has experienced an 88% increase in opioid overdose deaths each year from 2013 to 2016 (2, 3). Substance use disorders (SUDs) include cognitive, behavioral, and physiological symptoms. Hallmark signs of SUDs include impaired control, cravings, social impairment, risky use, and withdrawal symptoms.
Because ketamine is consumed in liquid and powder form, or mixed in these forms with other stimulants—there is a high chance that a person using this drug has little to no idea of how much is being consumed.

Behavioural and social symptoms of ketamine addiction:
From potential side effects to dosage, it is safe to say that the medical community knows almost everything there is to know about ketamine, though it continues to be understood better and better as its use cases expand. In summary, studies show that ketamine infusions may reduce craving and promote recovery for people with alcohol, stimulant, and opioid use disorders. That the effects of ketamine on craving and substance last months across studies are especially exciting. For depression treatment, by contrast, effects usually only last a few weeks. Science continues to analyze and explore new ways to look at how traditionally used medicinal substances can be used for addiction recovery.
Mean arterial pressure, heart rate, and serum cortisol were significantly lower in the ketamine group during opiate antagonist induction under anesthesia. This lack of group differences may be related to initial opioid antagonist treatment in both groups or to administration of ketamine while the participants were unconscious. Finally, future ketamine trials should include evaluation of optimal dose and frequency schedules. The majority of the studies have utilized prior depression trial dosages of 0.5–0.8 mg/kg IV ketamine, although a few studies utilized doses of 2–2.5 mg/kg IM.
The world is changing. Medicine is changing. We’re leading the way.
As a physician, I am able to witness firsthand the healing power of these types of experiences that may occur. It should be noted that these experiences do not occur for every patient, and it is unclear to me why some patients seem to consistently have this type of experience while others do not. We have a circuit in our brain, called the default mode network, whose activity is linked to the endless ruminating chatter in our mind about the past and the future.
- A drug like ketamine could be part of a medication-assisted therapy approach, meaning it is a supplement to a comprehensive program that must include a behavioral component, such as cognitive behavioral therapy; it is not a magic bullet.
- Ketamine was originally developed as a safer alternative to PCP for inducing anesthesia prior to surgery.
- Esketamine (Spravato), the S-enantiomer of racemic ketamine, was approved in 2019 for treatment-resistant depression with an oral antidepressant in depressed patients with acute suicidal ideation or behavior.
- Also, just having a break from negative thinking can help one to have a reset, and give one hope of a different way of thinking and being.
With limited treatment options, a myriad of non-FDA approved medications (e.g., gabapentin, clonidine, bupropion) are tried as standalone pharmacotherapies and in conjunction with behavioral interventions. Ketamine is defined as a Dissociative Anesthetic due to its sedating effects, which produce an out-of-body experience where users feels detached from themselves and their surroundings. Ketamine also distorts the user’s perceptions of sight and sound and can make it difficult to move.
To accurately isolate and measure the effect of the active treatment, outcomes need to be compared between groups to obtain valid information about the therapeutic potential of a treatment. Tolerance can build to the effects over time, requiring greater doses of the drug to reach the same level of effect. The dissociative effect alters the users perception of light and sound and produces feelings of detachment from self and surroundings. Ketamine is a noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist, and it blocks HCN1 receptors. However, at higher doses it may also bind to the opioid mu and sigma receptors. It can exhibit sympathomimetic activity which can lead to rapid heart rate and elevated blood pressure.
