General Information Services Faulty drug test. Reported a drug I never took and did not report prescriptions I take. This caused me to lose my job. Chapin South Carolina

Aplied for a job at Smiths grocery store and was honest about my criminal history. They hired me and after a 2 week training period I was assigned to a store. They then did a swab drug test and sent it to GIS. It came back as positive for cocaine but negative for oxycodone that is prescribed by my doctor. I asked for a retest but GIS stood by there result even when I told them about my prescriptions. My doctor sends me for periodic blood tests and I always test positive for oxycodone and not cocaine. The oxycodone is prescribed to me for a neck injury from a car accident but it has no impact on my job performance as I take them to sleep well. I was then told Smiths would not continue my employment even though I was performing my duties. Now I am unemployed and lost a job I tried to get for years all because of GIS mistake and not wanting to give me another chance to prove them wrong. The irony of the whole ordeal is for 7 years I have only shopped at Smiths because of thier customer service and I feel that this is what I do best only to have an outside agency fail in that matter.
