Prescriptions and Urine Test

[Aslan]

Hi.
I am a pain patient who has to take regular pee tests now. I am also 420 friendly as it helps the pain. I have to take two tests coming up in 2 weeks.
I am purchasing a urinator and using someone's pee. I thought that would be the end of it.
But it occurred to me that I am on like 13 prescriptions. Should I worry about them not showing up on the test? Should I put some of them in the urine? I really have to pass this test to get a procedure done on my back next month.
I appreciate your time and help.
Thanks!!
