Is it illegal to use someone else's pee during s drug test?

Isn't it illegal to use someone else's pee during a drug test? I just saw a post and quite a few people are telling the OP to use someone else's pee or a little child's pee.🤔🙄 I'm just curious if it's illegal or not? I'm not quite familiar with this so excuse my ignorance.
