If yes, drug test is not really an issue between fighter who fears blood extraction.
True... But I don't think that the normal sanctioning bodies (ie NSAC) do CIR testing. So, you have to go with a more stringent testing body (ie USADA or VADA) and they do both, blood and urine testing...
I don't think you can tell USADA or VADA that we only want to get urine testing done... I'm sure under those circumstances fighters would have something in their system only detectable though blood.
