Ketamine Found to Be a Highly Effective Treatment for Severe Depression

One doctor calls it “75 percent effective.”

Ketamine, or “special K,” as it’s affectionately known among ravers, has been used as a party drug since the ’60s. It causes relaxation and vivid hallucinations, and users who take too much fall into a knocked-out state known as a “K-hole.” It also has been used in emergency rooms to help people in extreme pain, and in veterinary centers as an anesthetic.


As this recent article in The Washington Post explores, the drug may offer many more medical benefits than previously known. In the past decade, doctors have been experimenting with the drug to treat severely depressed patients who most thought couldn’t be helped. Ketamine has been so successful at helping people who had experienced little improvement through antidepressants and psychotherapy that the American Psychiatric Association may soon endorse it for use in cases of treatment-resistant depression.

Ketamine has been unusually effective in treating patients contemplating suicide, thanks to its fast-acting antidepressant effect. These effects are known to last much longer than the initial dosing. News of ketamine’s success has created excitement among people who have spent years cycling through antidepressants, mood stabilizers, and cognitive therapies with little success.

Enrique Abreu, an Oregon anesthesiologist, has seen very positive results over the past few years. “The response rate is unbelievable,” Abreu told The Washington Post. “This drug is 75 percent effective, which means that three-quarters of my patients do well. Nothing in medicine has those kind of numbers.” Ketamine is successful with patients who haven’t responded to traditional treatments because it works differently. “Ketamine almost certainly modifies the function of synapses and circuits, turning certain circuits on and off,” explained Carlos Zarate Jr., a leading ketamine researcher. “The result is a rapid antidepressant effect.”

Although ketamine’s future looks bright, there’s still more research to be done. Gerard Sanacora, director of the Yale Depression Research Program, told the Post that it may take awhile before they better understand the long-term benefits and risks. Currently, ketamine is approved by the FDA, and doctors are able to prescribe it for off-label use.

Seventeen-year-old Swedish climate activist Greta Thunberg made a dramatic speech Tuesday at the World Economic Forum in Davos, Switzerland.

In her address, she called for a public and private sector divestment from fossil fuel companies

"Immediately end all fossil fuel subsidies and immediately and completely divest from fossil fuels. We don't want these things done by 2050, or 2030 or even 2021 — we want this done now," she said.

U.S. Treasury Secretary Steven Mnuchin mocked the teenager on Thursday during a press briefing in Davos.

Even though marathon running is on the decline, half a million people signed up to participate in the 2020 London Marathon. It seems wild that someone would voluntarily sign up to run 26.2 miles, but those half a million people might actually be on to something. A new study published in the Journal of the American College of Cardiology found that running a marathon can help reverse signs of aging.

Researchers at Barts and University College London looked at 138 first-time marathon runners between the ages of 21 and 69. "We wanted to look at novice athletes. We didn't include people who said they ran for more than two hours a week," Dr. Charlotte Manisty, the study's senior author and cardiologist at University College London, said per CNN.

Last Friday, GOOD reported on an infuriating incident that went down at a Massachusetts Target.

A Target manager who's come to be known as "Target Tori," was harassed by Twitter troll David Leavitt for not selling him an $89 Oral-B Pro 5000 toothbrush for a penny.

He describes himself as a "multimedia journalist who has worked for CBS, AXS, Yahoo, and others."
