It can cause hallucinations and hasn't been approved by the FDA for use in depression. It is still in trials to evaluate it's safety and effectiveness. The effects wear off in a couple of days so it is no cure. It knocks you out, being an anesthetic, so that means an anesthesiologist along with the psychiatrist and nurse have to be present. They have to be on cardiac monitors and be given oxygen. They will need to be under observation afterwards, just as people who have had surgery have to be in a recovery room for awhile after coming out from under anesthesia. In short, it is not ready to be given out as an outpatient drug.
