What i'm saying is that these particular drugs are shunned by the public eye as being the standard of care, and it will be the public eye to a major extent that one will be judged by. Hence, one takes a second look at things. If protocol absolutely says ketamine then its one thing (at which point I'll be telling them to take it up with the person whom wrote the protocol.), If it allows for a choice, then one should opt for the better of both worlds if possible (even if it will make the job a bit more problematic), unless one is prepared to hire the experts to prove their choice would be superior to any and all of the alternatives. (and trust me the non-medically informed lawyer WILL try that point with a quickness.) Protocol IS the "standard of care". Giving a human a drug that was never originally intended for humans in the first place has the appearance of being below the standard of care, at least at first appearances. That's one of the major reasons we have protocols. It's really the concept of not being afraid to grab a bull by it's horns.
