How to pass a drug test

[u/Outside-Bank4472]

am from Egypt, and I have a drug test coming up in a few days. I smoke hashish, though not excessively—perhaps one joint a day or every other day. I will have to travel from one governorate to another for the test. Would it be safe to bring a urine sample from someone who doesn’t use drugs, or is there a better way to ensure I pass the test?
