I am in a custody battle with my soon to be ex wife, and she has made allegations of pot use in the court documents. In order to blunt these accusations, my attorney wants to bring a clean drug test result into court to prove I am not using pot. Our court date is on May 20, 2013. I have not smoked weed since April 1, 2013. I plan to take the test on May 19. This means 49 days will have passed since I smoked. I was a rather heavy, daily smoker. I am a rather big guy also, 6'1" and about 230 lbs. I have read lots of conflicting information as to how long it stays in your system, and I am very nervous as to whether I will pass the urine test, or whether I need to look into a cleansing or detox product. Is 49 days enough time for a daily smoker to pass a piss test? Any advice would be greatly appreciated.
