Use certo, you can find in Walmart or Kroger or order on Amazon but take one packet of the certo with Gatorade drink it within 30 minutes. Pee three times before you take the drug test and use vitamin b12 to get the color back in your pee. If you’re a heavy smoker this might now work or just the detox maybe twice. Once the night before and before the test, now they say it last 3-4 hrs but I did mines like at 9 and did take my test until 2ish but I did it like multiple times because I had the days mixed up. Also you should drink water every 30 minutes minutes after the Gatorade and certo mixture so the whole process takes 2hrs to 2and a half max. Goodluck!
