As is often the case, enthusiasm and marketing have gotten ahead of the evidence. For those who abuse ketamine via insufflation (“snorting”) adverse reactions may be less serious, but still present. Fast heart rate, high blood pressure, hallucinations, and impaired consciousness upon presentation to the emergency department may be most common effects with “snorting”.

In an emergency? Need treatment?

While ketamine is safe to use in controlled medical practice, it becomes hazardous if someone takes it for recreational use as it may result in potentially life-threatening adverse effects. Withdrawal symptoms may include chills, sweats, excitation, hallucinations, teary eyes, and drug cravings. Keller ketamine addiction advises avoiding ketamine treatment if you or your family has a history of psychosis. Ketamine can cause disassociation, which experts have linked to hallucinations and other symptoms of psychosis.

• Though they’re far from perfect treatments, ketamine and esketamine mark a breakthrough for treatment-resistant depression.
• Individuals who take ketamine recreationally report sensations, such as being separated from their body or a pleasant feeling of floating.
• As a result, the medication has been used as both an anesthetic and an analgesic (a medication that has pain-relieving properties).
• According to the Drug Enforcement Administration (DEA), recreational forms of ketamine are commonly known as Special K, KitKat, Vitamin K, and other slang terms.

Possible Benefits of Ketamine Therapy

Secondarily, the drug distributes into peripheral tissues with a slower elimination half-life of up to 3 hours, undergoes hepatic metabolism and is excreted in the urine. More studies are needed to figure out the ideal treatment dosages and frequencies to maximize the benefits of ketamine while minimizing its side effects. A growing body of research supports the benefits of ketamine for depression. Though they’re far from perfect treatments, ketamine and esketamine mark a breakthrough for treatment-resistant depression.

Potential Health Benefits of Microdosing Psychedelics

Children metabolize ketamine faster than adults, so higher dosing is required. However, older patients are slow metabolizers and need lower dosing. The antidepressant effects of ketamine wear off in hours, days, or a couple weeks in people who only get a single infusion. Ketamine itself is not FDA-approved to treat depression, but a derivative of ketamine, esketamine, is. The drug is delivered by nasal spray and is designed to be administered alongside a traditional antidepressant. It was approved specifically for treatment-resistant depression, or depression that has failed to respond to other antidepressant medications.

Safety and side effects

• Safety is really where things open up, because this is a drug that affects perception and can cause hallucinations and visions.
• There is no smell or visible signs when a person takes it; it can be ingested, injected, or smoked.
• Ketamine and esketamine are chemically very similar, but they’re two different drugs.
• This is a dissociative state where you feel detachment from your body and your environment, per a study published in Anesthesiology in November 2020.
• Ketamine was discovered in 1956 and first synthesized in 1962 by Calvin L. Stevens.

One advantage of ketamine over other antidepressant medications is how fast it works. Research from 2018 suggests ketamine may work by binding to the N-methyl-D-aspartate (NMDA) receptor in the brain to block glutamate. Millions of Americans are self medicating with alcohol, and others increasingly with marijuana, and so on, all the time. I certainly think clinicians and patients should be talking about these things. With ketamine, we have a drug that has unclear effectiveness with some very well described dose-response and cumulative adverse effects that run all the way up to death.

• Negative beliefs about yourself and the world — like “Nobody cares about me,” or “I’ll never succeed” — may contribute to depression.
• Ideally, the practitioner should monitor the session carefully to watch for side effects, including patient distress.
• Ketamine interacts with several protein pathways in the brain important for memory, plasticity, and learning.
• Despite these positive results, the authors warn that data on the use of ketamine for this condition are limited, so practitioners should consider the risks of the drug before prescribing it.
• Prolonged or repeated use can lead to psychiatric issues, including psychosis and flashbacks.
• At his clinic, Stewart only sees patients who have referrals from a doctor who diagnosed them with treatment-resistant depression.

May Be Useful in Anxiety Disorders

Emergency responders may give it to an agitated patient who, for example, they have rescued from a suicide attempt. That’s how Ken Stewart, MD, says doctors began to realize that the drug had powerful effects against depression and suicidal thoughts. Jeff Winograd, who’s lived with depression for more than 25 years, says ketamine treatment saved his life.
