Researchers say a drug that's used in hospitals and abused on the streets, may dramatically change your state of mind.
In hospitals, it's a commonly used anesthetic. In the clubs, ketamine is a popular hallucinogenic drug.
But what can make ketamine truly "special" for millions of people, is its potential to, quickly and effectively, treat chronic depression.
Dr. Rerard Sanacora of the Yale Depression Research Programm said, "It has been one of the major new findings in the field for at least a few decades."
Unlike standard antidepressants, which can take weeks or months to work, Yale researchers say ketamine can improve your mood in hours.
However, researchers are still figuring out how to safely administer ketamine as a routine treatment.
"It's not a strongly addictive, but does have high abuse potential."
While ketamine is currently not FDA approved for depression, a growing number of private clinics across the country are offering it "off label." Doctor Gerard Sanacora is concerned.
"There are several very important questions that we still don't know about ketamine and probably the most important is what is the long term benefit? Is repeating dosing of this actually a good idea?"
His advice, talk to your doctor.
Doctors say the fast-acting quality of ketamine can help save lives of those in danger of committing suicide.
Infusions at the private ketamine clinics can run you thousands of dollars, with no guarantee of any results. They're also not covered by insurance.
