don't worry to much, if worse comes to worse and you failed the swab test, just claim that the test is BS and ask to take it again... youshould be fine, saliva tests are only good up to like 5 days. so stay clean until you are in for sure

good luck man!!!! and if it helps weed is NOT a drug! so drug tests shouldn't detect it right? i wish, just trying to give you some optimism

When it's all said and done just smoke a fat blunt to relieve the tension
