I don't smoke on the regular, but I did smoke weed on November 2nd and than again on November 6th. (Haven't smoked since) I have a urine drug test this Thursday. I'm tall, and if you were to look at me you wouldn't think that I am 230lbs but I am. I am not that active either. So Will that effect anything??) I'm planning to drink water all day tomorrow. I also drank a whole big bottle of cranberry juice and another tomorrow. I took 500 mg of Niacin at 9:15pm today and I was wondering will I be okay for my drug test on Thursday? What should I do?
