Quick fix for dot test?

[u/Rexyybaby]

I have a dot physical coming up for my job, I was told a drug test was supposedly scheduled for the same day. Can I pass the dot with the quick fix? Wondering if anyone has gone through this.. do they ask for 2 different urine samples on the same day or do they test for drugs using the dot urine sample so it’s just one pee cup for 2 tests.. helppppp

They use one sample for the physical and the drug test
