What is a one shot concentrate? What is your approx. body fat? Before yesterday, how long has it been? What kind of testing will be done, urine? If urine, will it be sent to a lab or is it a strip that changes color?
I meant, before yesterday, when is the last time and how often have you smoked.
Thc is fat soluble, so, if you aren't a fatty it will be easier on you. That being said, I am slim, I have smoked the day before a test (sent to a lab, which is alot harder to pass), and I passed. Granted, I hadn't smoked for weeks before that. The more often you smoke, the more it absorbs in your fat cells. As for your detox I'm not familiar. I have,however had very good luck with Vale. If you can find d it, I highly recommend it. Good luck!
My Advise to you is to start drinking water tonight slowly but drink at least a gallon if you can. Hours before the test drink coffee then more water after that Gatorade, red bull and Vitamin be at least 1 1/2 hours before the test to put color in your urine. This works for me and is a safer bet than a detox as the labs have ways of picking up those types of masking agents.
