urine is easy, blood i doubt you can fake, thus why it would be considered as a last resort i'm still confused why they're doing a blood test... and if they're taking him for a tox screen at an actual buisness that specializes in such things, well i hope they got the money to cover it....

if i remember right, it cost my wife's job around 700 to do a complete screen (but that also included things like xanax, valium, vicodin, ect ect..)
