I made an account just to help you with this. It is really easy to pass a urine test.
You need to drink a lot of water all at once. The goal is to get your body to bypass the adsorption of water and have your kidneys get rid of it. Your urine will look clear. Most people will tell you this will force a retest.
2nd step is to eat a lot of high protien food like a pound of so of brisket. The goal here is to get your urine foamy. This is something they look for when checking a for quality sample.
3rd get some b12 like less than half a 5 hour energy. The other main thing they loom for is color to clean or dark is also bad. They same with to bright which is what you get with an excess of b vitiams.
This will need to be done on the day of the test. Don't start 2nd step till you get the first one done same with 3rd step and step 2. Just keep drinking water all day.
I found this on a doctor's blog many years ago while trying to get around my own test. Also stop smoking till your test and if retested do the same routine.
Anyone really want to scare the testers and possibly get a lawsuit out of it drink a lot of pureed beets, it turns your urine red not just your poo!
