Elon Musk, Ketamine, and the Future of Depression Treatment

Don Lemon’s short-lived interview series on X (formerly Twitter) kicked off with a bang—and then fizzled just as quickly. His first and only guest? None other than X owner Elon Musk. The conversation took an unexpected turn when Musk opened up about his use of ketamine to manage depression.

“There are times when I have sort of a … negative chemical state in my brain, like depression I guess, or depression that’s not linked to any negative news, and ketamine is helpful for getting one out of the negative frame of mind,” Musk shared, adding that he uses “a small amount once every other week or something like that.”

For many, Musk’s revelation wasn’t exactly shocking. The use of ketamine for depression has been on the rise, with prescriptions skyrocketing from 0.55 per 100,000 people in 2017 to over 3 per 100,000 in 2022. Once an obscure treatment mainly reserved for anesthetic purposes, ketamine has now become a serious contender in the fight against treatment-resistant depression (TRD). Researchers are taking notice, publishing groundbreaking studies that explore the drug’s potential.

Here are three of the most intriguing recent studies published by The Primary Care Companion for CNS Disorders, shedding light on ketamine’s role in treating depression.

1. Ketamine-Assisted Psychotherapy: A Game Changer for Treatment-Resistant Depression?

When traditional antidepressants fail—and they often do—patients diagnosed with treatment-resistant depression (TRD) are left scrambling for solutions. TRD is typically defined as depression that persists despite at least two failed treatments. Patients suffering from TRD often battle persistent self-criticism, self-doubt, and intense feelings of worthlessness, making it one of the hardest forms of depression to treat.

A recent study explores how ketamine, combined with psychotherapy, could offer new hope. Unlike standard antidepressants, which can take weeks to work (if they work at all), ketamine’s rapid-acting effects can provide nearly immediate relief. Ketamine-Assisted Psychotherapy (KAP) takes this a step further by integrating guided therapy sessions into the treatment process. The result? A profound shift in perspective, allowing patients to confront and reframe negative thought patterns.

While KAP is still in its early stages, experts from Massachusetts General Hospital/Harvard Medical School believe it could revolutionize how we approach depression treatment. More research is needed, but the potential is undeniable.

2. IV Ketamine vs. Intranasal Esketamine: Which Works Better?

Since the FDA approved intranasal esketamine (a derivative of ketamine) for TRD in 2019, the debate has raged: which is better—IV ketamine or intranasal esketamine?

A recent letter to the editor delves into this question, analyzing studies comparing the two. Some research suggests IV ketamine might actually be more effective, with higher response and remission rates. Yet, despite these promising results, IV ketamine has yet to receive FDA approval for depression treatment—possibly due to lingering concerns over side effects.

Insurance coverage is another major roadblock. While esketamine is FDA-approved and covered by some insurance plans, IV ketamine often isn’t—leaving patients to foot hefty bills. The authors of this study argue that recognizing ketamine’s full potential could drastically improve outcomes for those who don’t respond to conventional treatments.

3. Real-World Outcomes: Ketamine in the VA Health System

Veterans face some of the highest rates of depression and suicide, making effective treatment options crucial. A study examining IV ketamine treatment in the Veterans Health Administration (VA) system offers some compelling insights.

Analyzing electronic medical records from 215 veterans, researchers found that after six weeks of IV ketamine treatment, 26% experienced a 50% improvement in depression scores, and 15% reached full remission. These improvements lasted for at least six months—a promising sign that ketamine could offer sustained relief.

However, the study also highlighted challenges, including the need to determine optimal dosing schedules and assess long-term effects. While IV ketamine isn’t a magic bullet, it’s clear that for some patients, it can make a life-changing difference.

The Road Ahead

The resurgence of interest in psychedelic-assisted therapy—including ketamine, LSD, MDMA, and psilocybin—signals a shift in how we approach mental health treatment. While more research is needed, the current findings suggest that ketamine could be a powerful tool in combating depression, especially for those who have exhausted traditional options.

As Musk’s comments reignite the conversation, one thing is clear: the world is paying attention. Whether or not ketamine becomes a mainstream treatment, its potential to reshape mental health care is undeniable.

Could we be on the verge of a new era in depression treatment? Only time—and science—will tell.
