Well I’m a bigger dude and a long time ago I was on probation i smoked all day every day for the first two years of supervision. Out of the blue I was assigned a new officer and they started testing me. Took me six months to piss clean and I tried every flush from the head shop/gnc, Apple cider vinegar, cranberry juice, I drank tons of water. After failing five months in a row I got desperate because I was looking at 25-99 years of my probation was revoked. So me being the amazingly bright 21-22 year old I was at the time I drank a cap of bleach and a ton of water. I finally passed, obviously I would not recommend that to anyone I was in a very bad state of mind and I honestly had quit smoking for so long I just wanted to be left alone. I didn’t smoke again until I was released from probation.
