to answer your first question: no. a urine test that checks for bacteria will not "look" for other substances in the urine. to your second question: if you inhale a small amount of secondhand marijuana smoke might it show up on a drug screen test? i'd guess it's doubtful but not impossible. it definitely won't show up on a urine culture designed to check for bacteria. i hope that helps!
will thc show in a urine screening where they are checking for bacteria? . if you are in a moving vehicle with the windows down and someone is smoking marijuana can it show in your urine test?
