    Ketamine has a reputation as an illicit party drug due to its hallucinogenic effects. But in a handful of ketamine clinics around the country, people who weren't helped by standard treatments are getting a series of infusions to ease their depression. The drug has also been used in emergency rooms for curbing suicidal thoughts, making it a potential lifesaver.

   Ketamine acts quickly -- often within hours or less -- and health care professionals who give it to patients at therapeutic doses say it has mild and brief side effects in most people. But it hasn't been thoroughly studied for long-term safety and effectiveness, and the FDA hasn't approved it to treat depression.
