My companion just lost an offer for a an amazing job to promote blood donation for a hospital (he believes in helping others and tried to make it his life's work). He has been out of work for 2 years do to 6 herniated disks do to an injury suffered on the job while working for the new york blood center. He was prescribed lidocain patches (700mg) for his intense pain. He lost the job offer at this new place because of a positive on his drug test. Could the patches have given a false positive? He wore the patch the day of the test as well. I desperately need info on this quick as this could mean the difference between loosing our home etc. We were dependent on this job.
