oooh oohh I know this one.. its a hallucinogen that is used to help people addicted to drugs break the addiction. during this usage they found that it also had pain management results. in germany they started research on the ketamine coma. where they use this drug to induce patient into a coma in hopes of remission. results were noted . they started this type of treatment in mexico and then they applied for a trial run in the CRPS/RSD facility in Fla. the treatment that is fad approved here in the states is the ketamine infusion. where like most treatments do not work for all but from what i have seen has had a good trac record. I myself would jump at the chance if it was offered. there is so much more to it than i described but i didn't want to lose your interest. lol. just too much to type right now
