i'm a little worried about the pre-employment test i took today. i'm 5 ft. and weight 118 lbs. moderate metabolism and smoker until i quit about 5 weeks ago. before that i ate a whole "magic cake" all by myself (so yummy i couldn't stop myself!!!). i tested myself twice about a week ago and failed one test. i'm thinking it may have been the route of thc administration that is giving such slow clearance of the thc metabolite. i took 4 aspirins last night and again this morning before going in. also took a multivite 1 hour prior with moderate amount of water...i don't believe i diluted my urine enough though. i was not urinating every 15-30 mintes. just curious if the aspirin will drop the ph of my urine and my sample will me considered adulterated. any input will be greatly appreciated.thanks!!!
