Truck Driver Forum - Failed drug test and refusal on dac report: I worked for the one of the largest truc...

I worked for the one of the largest trucking companies out there for 4 years with a clean record.Had 4 previous drug tests(3 of them were random)and passed with flying colors because I don't do drugs or drink.In January I got called for my 5th random in La.Went and took the test,not worrying about it cause I knew I had no reason to fail it.Much to my surprise I got the call a week later that I had failed for THC.I couldn't understad what had happened.They asked me if I had taken anything or smoked anything in the last week.Just alot of Advil because of my allergies and sinus.Later I got the call from my boss telling me that I was being fired.I asked for another drug test then and there and they said no.So I told them I quit because there was no way I should have failed any kind of drug test and after my good record with this company ,they wouldn't give me the chance to proof that the test was wrong.He's like "you could have gone home and cleaned up."I don't know alot about pot but I don know it takes alot longer than a week to clean your system out.I pretty much told him to stick that job where the sun don't shine.So after a couple of weeks I got my fired notice but the dates were wrong on it.Their showing that they knew on the 8th of Jan. that I had failed.I didn't take the drug test untill the 12th.So I send off and got a copy of mu dac report in Feb. and again in June and there the same.The company reported that I quit and my failed drug test is not on it after 6 months.What does that mean? Not real sure what I should do now.Am wanting to get back in a truck but not sure if its going to show up or not.Any suggestions would be appreicated. THANKS!
