Where do you get your numbers my friend? 97% of the jobs in America requires them to give blood? I use to do administer drug tests and do phlembotomy. The main reason why companies prefers urine because it is cheaper. The average cost of a urine test is about $44. For a company to get blood from and employee normally takes a court order or something major has to happen like if you were driving a company vehicle and you'll get in to an accident. If they suspect a DUI then with the proper paperwork can retrieve your blood by any means neccesary. I've seen people try to beat the urine test and even with the stuff they use to try to beat the test comes up as well. Most jobs that involve driving, serious money handling, healthcare or construction requires drug testing. The thing is they do this seldomly. The only job that does drug testing constantly is the military and still a few slip through the cracks.
What I'm getting at is who is going to over see this drug testing. Because of course we need a commision that over see this. I mean there is already a commision in boxing that does over see it. And so far there have been alot of people who got caught testing positive for banned substance. People like Fernando Vargas, Roy Jones, Tommy Morrison, Orlando Salido, james Toney, Omar Nino, Mike Tyson, Pernell Whitaker, Juan Guzman, Ricardo Mayorga, and Mariano Carrera In MMA you have Royce Gracie, Stephan Booner, Johnnie Morton,Tim Persey, Vinicius Kappke de Quieroz, Chanel Sonnen, Cesar Gracie, Bas Rutten, Diego Sanchez Thiago Alves, Vitor Belfort, Pawel Nastula, Sean Sherk, Josh Burnett, Kevin Randleman, Tim Silva, Bob Sapp, Ken Shamrock, Chris Leben, Phil Baroni, Johny Morton, Jason Winther, Bill Mahood, Hermes Franca, Kirill Sidelnikov, Karo Parisyan, Pawel Nastula, and Carina Damm. They all fall under the same state commision and they all came up positive. Check the history. Just like OST. There has been olympians that have beaten the test. So what makes one test better than the other. One test professional athletes and the other tests amateur athletes. All the years the testing it seems like it has been working. As long as technology keeps improving there is going to be a few individuls that will skate by.
