Urgent. How long will it take to clear?

Hey All,

I'm 5'10 and 150 pds. About 5 days ago (on friday night) I smoked 4-5 bowls. (1.5 of dank and the rest of mids). My mom is planning on springing a test on me within the next week. On monday night I drank 2 1/2 litres of cranberry juice, and have been drinking water and green tea alot ever since. I'm pissing about 6-8 times a day.

If I get tested in the next couple of days what would you say my chances of passing are?

Also, should I get a substitute in line just in case or do you think I will be clear? My mom might watch so I'm not exactly sure.
