I fail to see why I should believe that it is only an anesthetic (never anasthetic, as you consistenly keep writing) and not a tranquilizer as well when I can find thousands of documents on .gov and .edu sites supporting its use as a tranquilizer. Surely you can come up with veterinary medicine documents that explain why it's not usable as a tranquilizer rather than making unsupported claims - since it's mentioned as a tranquilizer always in veterinary and not human contexts.
