What are the chances of passing my drug screening?

I have a drug test tomarrow at 3:30, I've been smoking for a week like a joint/blunt aday. I've drunk like over 80 oz. of water so far my urine is clear.. I need to know something I can eat to turn my piss yellow.. I looked around the house and found some things they told me to get on the sticky.. so I have:
- Many green tea formula supplement's some kind of herbal pill, 1 pill = 3 glasses of green tea or something.
- Aspirin that isnt tylenol or adv
- Vitamin C pills

I dunno Imma drink like 150 oz of water tomarrow before I have my drug test, now if I can just eat or drink or take something to turn my pee yellow, I was hoping some of the pills I listed above will help me...

I have no hope in passing this test.. I drink water and it seems thats all I can do to help, Im hoping these pills will help me or should I drink bleach? people tell me it cleans my system..

Please someone tell me something I really dont wana go to juvi..

I can endure some sickness.. so be afraid to list harmful ways.. I'm willing to go to any extent.
