Hi there ~
I understand your concerns. Marijuana stays in your system from 2-5 months from last use depending on how much and for how long you were using marijuana before quitting. I also believe that you cannot do anything to make your urine clear from marijuana during this time. I hope this helps and you get yourself to a psychiatrist
to go to rehab and correct your medical problems having resulted from chronic marijuana usage.
I hope this helps. Take care of yourself and have a lovely day!
