Synthetic urine is illegal where I live. Any other suggestions. I have been drinking plenty of water over the last 48 hours. I am skinny (125#). I am a pretty regular smoker, but in the last week I have only smoked about 4-5 Js (mainly in the beginning of last week). I've got my B12, plenty of water and gatoraid, and last night I picked up a bottle of Protox and 4 pre protox pills you take the night before (as recommended by the local headshop). I took the pills 12-18 hours before I took the protok. This morning I woke up and ate a high fiber breakfast cereal. Two hours later I drank 24 oz. of water. An hour after that I took the protox followed by a bottle of water. I drank gatoraid the rest of the morning. I took a home drug test for mari about four hours after taking the protox. The results were positive. I have taken a test before after smoking a J two days prior and passed by drinking a lot of water. I thought this might mean I have an awesome metabolism but I guess not. My question is are the home test you buy at rite aid and walgreens acurate? What should I do? Like everyone else, I have to pass to keep my job I enjoy. I may be able to buy some time but the more time away from work the further I could be working myself in a hole. Please, any suggestions????
