The History of Ketamine: From Battlefield Anesthetic to Mental Health Breakthrough
Ketamine has a story. And it’s far more than a party drug or painkiller. It’s a medicine with a surprising past—and a powerful future.
The Beginning: What Is Ketamine?
Ketamine's story began in 1962 when Calvin Stevens synthesized it at Parke Davis Laboratories. Research published in Acta Neuropsychiatrica documents that it was developed as a safer alternative to phencyclidine (PCP), addressing the need for a more manageable anesthetic agent.
By 1970, the FDA approved it for use as a surgical anesthetic. Doctors used ketamine during the Vietnam War to treat injured soldiers. It worked fast and didn’t slow down breathing—huge advantages in the chaos of war.
The Medical Uses Expand
Over time, ketamine found new roles. It became common in emergency rooms, operating rooms, and for veterinary procedures. It also became popular for use in children and patients with asthma because it kept airways open.
This reputation helped define the ketamine drug class: a dissociative anesthetic. That means it creates a sense of detachment from the body or environment. For decades, it was used safely and effectively in controlled settings.
From Anesthesia to Mental Health
The discovery of ketamine's antidepressant properties marked a paradigm shift. According to BMJ Mental Health, this revelation emerged from clinical observations in the early 2000s, leading to systematic investigation of ketamine for treatment-resistant depression. Researchers noticed something during anesthesia recovery—patients with depression felt better. Fast.
This sparked studies on what ketamine does to the brain. It turns out, ketamine affects glutamate, a neurotransmitter linked to learning and memory. This led to a new understanding of its antidepressant potential.
Current research demonstrates ketamine's efficacy across multiple conditions:
Ketamine for depression: Studies published in The Lancet Psychiatry show rapid and significant improvement in treatment-resistant depression and ketamine for anxiety are common in treatment-resistant cases.
PTSD: Clinical trials in JAMA Psychiatry demonstrate meaningful symptom reduction after ketamine treatment.
What Does Ketamine Feel Like?
Patients describe a range of sensations: calm, floating, seeing visuals, or a deep sense of introspection. These acute effects of ketamine are part of the healing process. In a safe, supervised setting, they can help people reframe difficult thoughts and emotions.
Side Effects and Misuse
Like any medicine, ketamine has side effects. These may include nausea, dizziness, or disorientation. Rarely, it can lead to bladder issues or dependency.
The side effects of ketamine depend on dosage, setting, and frequency. In recreational settings, it can lead to risky dissociation—sometimes referred to as the “K-hole,” a state of extreme detachment. But in clinical care, doses are much lower and carefully managed.
Ketamine Today: A New Era in Mental Health
Modern ketamine therapy includes infusions, lozenges, or injections. It’s paired with integration therapy to help patients process their experiences. Studies now show it can rewire the brain and create long-term emotional change.
Many ask, What is ketamine prescribed for today? The answer: depression, anxiety, PTSD, and sometimes chronic pain.
Is Ketamine Addictive?
Used recreationally and without supervision, ketamine has abuse potential. But in medical use, especially with structured protocols and professional guidance, ketamine addiction risk is very low.
Ketamine and the Brain
Ketamine increases neuroplasticity. That means your brain becomes more flexible—more able to learn, change, and grow. This is part of why it helps where traditional medications fall short.

Final Thoughts: From Then to Now
Ketamine’s journey has been unexpected. From war zones to wellness clinics, it’s evolved into one of the most exciting tools in mental health. But it’s not magic. It’s medicine—meant to be used wisely, safely, and in the right setting.
