"At a mental hospital near Yale University, a depressed patient was being injected with ketamine. For 40 minutes, the drug flowed into her arm, bound for cells in her brain. If it acts as expected, ketamine will become the first drug to quickly stop suicidal drive, with the potential to save many lives. Other studies of ketamine are evaluating its effect as a vaccination against depression and post-traumatic stress. Between them, the goal is nothing less than to redefine our understanding of mental illness itself."
I suppose that could work just fine for humans. Interesting idea.
I've had the Vet out here and he's given Ketamine injections to my horses before. But I do remember him telling me that it's a opiate based medicine also.
I hope it really works for the ones who need it.
