Took a pre-employment drug test last Wednesday. No word yet! My ONLY concern is that I took some concerta (un-prescribed, yes I know bad bad bad, but I am an undiagnosed ADD and was about to receive my diagnosis on paper when my insurance ran out) I tried my friends to see if it would bring me relief. I took one a day, don't remember the mg but I know it was suppose to be a high dose, for several days (5 or 6) after not much of a change I never touched it again.. Is this going to fail my drug test? I can't believe after going through years of terrible luck I could be my own demise of a break through!
