I have failed a alcohol bio marker test. I drank the day before and out of nowhere they checked me for alcohol and drugs and failed the alcohol for probation. Well I drank Wednesday and I report this coming Wednesday so more than likely I well get checked. I heard with this new biomarker test they can detect for up to 3 weeks and if its true how can I not fail the test. I only have 1 year left on probation and don't want to go to jail:-(
