Yes a woman can use a man's urine and they will not know the difference. I know this for a fact b/c I've done it before. I used my b/f's urine to pass my drug test.
Can A Woman Use A Mans Urine To Pass A Drug Test?

No because there are certain traces in chemicals in a woman's urine then are certain traces in a mans. So, if you want to be blown out of the water I would not think of trying it.
