Where does urine pass through to get out of the body?
It passes out through the urethra.
It depends on how long ago you smoked it. Your body gets rid of poisons through your urine. It is excreted in your urine. They test for it by testing your urine to see if it is getting rid of that poison. If it was long enough ago, your body should have finished getting rid of it. Then you should pass the drug test.
