Hey you should be alright. I was a daily smoker multiple times a day for years before I stopped for probation tests and I took NIDA 5 test on my 20th day and passed. Everyone is different but if you are worried read the sticky dilution thread. I didn't follow it exactly but just to help I just drank a sports drink and took 2 aspirin and passed no problem. Try to urinate 1 or 2 times prior to the test just to get what may have built up out of your system. You'll be alright good luck
