If you use someone elses pee when taking a drug test will it work??

Answer:
Sure.

Your difficulties are in how to make the delivery and what might be in that person's pee.

For instance, maybe that person has more issues than you do...

How carefully the watcher performs his/her job when you fill the container and how creative you can be in creating the holding container and delivery tube pretty much dictate how well you will perform when trying to give the other pee rather than your own.

Good luck... hope you're asking 'cause you want to convince a friend to take his/her own chances.
