Drug Class and Schedule

It is approved for use alone or with other medications in medical environments for pain management and rapid sedation. The Drug Enforcement Administration also separates drugs by schedules ranging from Schedule I to Schedule V.
Ketamine is a schedule III drug. Like other drugs from the same group, ketamine has various medically-acceptable uses and moderate potential for abuse and addiction. Other drugs that are categorized as schedule III include suboxone, Tylenol with codeine, and anabolic steroids.4

In early 2019, the Food and Drug Administration approved a ketamine-based nasal spray called esketamine (Spravato) for depression treatment. Questions about “how long does ketamine stay in your system vs. other depressant drugs” led to expedited FDA approval.

A study published in the Journal of Clinical Psychiatry in late 2022 indicated that ketamine infusions led to significant symptom reduction for individuals with depression. The study of more than 400 patients showed as many as 72% experienced an improvement in mood, and 38% were symptom-free after ten ketamine infusions.7
Ketamine Side Effects
The effects of ketamine use depend on how it is introduced to the body and how much or how often one uses it. Specific details on how long does ketamine stay in your system in quantities sufficient to cause side effects also vary from person to person. Within a couple of minutes after taking ketamine, it is not uncommon to experience elevated heart rate and blood pressure. But over the next ten to thirty minutes, both heart rate and blood pressure decrease, sometimes to the point of unresponsiveness.
It is possible to experience dilated pupils, salivation, muscle stiffness, and involuntary rapid eye movements. Ketamine use can also lead to nausea and dangerous levels of sedation. Ketamine is an anesthetic, so it reduces levels of sensation and feeling in the body. Some people become confused and nauseous. Others are detached and experience a “dreamlike” state.
What Does Ketamine Do?
Ketamine can cause hallucinations, panic attacks, agitation, and short- and long-term memory difficulties. Because your perception of pain and discomfort is dramatically altered when using ketamine, it is possible to injure or severely hurt yourself and be unaware of it until Ketamine wears off.
How Long Does Ketamine Last?
How long does ketamine stay in your system? Ketamine is a fast-acting drug, so it takes between fifteen minutes and one hour to take effect, depending on how it is used. The “high” from taking ketamine can last between thirty and sixty minutes. Many people experience a period of low mood that can last for several days after using ketamine.
Ketamine Withdrawal Symptoms
Many studies suggest a moderate risk for physical dependence on ketamine. Chronic and frequent users often experience psychological dependence and cravings for the drug when they try to reduce or stop using it entirely. Like many drugs, repeated use can lead to tolerance to its effects. Tolerance requires higher and more frequent doses to achieve the same “high” once attained with lower doses.
This pattern can inevitably lead to addiction. Studies suggest that withdrawal from ketamine may be similar to other addictive substances. For example, cocaine withdrawal leads to powerful and sometimes overwhelming cravings for the drug; however, not necessarily the physical symptoms.8
Examples of Ketamine Withdrawal Symptoms
Examples of common ketamine withdrawal symptoms include depression and anxiety, mood swings, difficulties with sleep, shaking, nausea and stomach upset, sweating, elevated body temperature, irregular heart rate and heart palpitations, and cravings.
It is important to be able to recognize ketamine withdrawal symptoms in order to effectively seek treatment when necessary.

Treatment for Ketamine Addiction
Ketamine addiction is primarily a psychological addiction. For this reason, it is essential to choose a treatment program like ours at Ripple Ranch Recovery near Austin, Texas, where each stage of your treatment and recovery are part of a single comprehensive program.
Detoxification
Detoxification is the first step in ketamine addiction treatment. Detox is necessary to allow your body to cleanse itself of any remaining drugs in a safe and supported way. When trying to quit ketamine “cold turkey,” cravings can quickly become overpowering, leading to relapse.
There is also the potential for certain physical withdrawal symptoms. For this reason, our providers will closely monitor your breathing and heart rate throughout the early stages of treatment.
Psychotherapy
Our inpatient rehab provides treatment programs for ketamine addiction. The duration of your treatment will vary depending on your treatment needs. As noted above, ketamine addiction is a psychological addiction. Thus, behavioral therapies such as cognitive behavioral therapy, dialectical behavior therapy, and acceptance and commitment therapy are often used.
Peer Support Groups
Peer support is a vital element of any SUD treatment program. Groups such as Narcotics Anonymous and similar groups allow individuals at all stages of recovery to give and receive support from others who share a similar journey.
Aftercare
Aftercare programs begin immediately after your primary treatment program ends. Aftercare is a vital component of relapse prevention. These programs generally include pre-scheduled medical appointments, ongoing therapy, peer support groups, and for some, sober living options.
