I'm 6'2 230 pounds I smoked for 15 years 2-5 times daily. It took me 35 days till my home tests came clean. I took my ua after being clean for 49 days and passed. On the day of your test just drink 40 ounces of gatorade piss one or two times before the real deal, and piss midstream for the actual test. You should be fine. Get a home test and test yourself first. Good luck. I'm on day 79 of being clean and still going.
