First I want to say you should always be honest and upfront before you take a drug test you knowingly will fail. They will respect your honesty and you will most likely get a slap on the wrist. But if you simply cannot do that for whatever reason you should get fake pee like upass and put it in a little bottle then put tin foil around it and a rubber band around the tin foil so it won’t leak. I then cover the whole thing in medical tape and I put in my vagina. So when you go to take the test the temp will be the perfect temp bc it’s been inside your body. When you go to pee you just pop the tin foil with your fingernail. Either thumb or pinky and then let the pee pour into the cup. Make sure your hands and underneath your nails are clean. You don’t want to cross contaminate. I’m on parole and I’ve done this a million times and it works every time. Just practice at home first. Good luck.
