if you hardly ever smoke, there's a chance you'll be able to pass it on monday. drink a lot of water today, eat some healthy food when was the last time, before Friday, that you smooked?
Make sure that you dilute the shit out of your piss. I've had to try to pass many drug tests, many failures and few successes. Try to drink at least 7 glasses of water down before you go, starting the first glass like 2-3 hours b4 the test.
Well, I smoke once a week. And yeah Ive been trying to detox yesterday and today. Green tea and cranberry juice. Before I go Im going to drink about a gallon of cranberry juice.
I'm on the other side of these drug tests and most people are caught. If the tests are for a good reason, consider actually stopping. Maybe its better for you in the long run. http://www.idmu.co.uk/drugtestcan.htm
im not sure if this works for everyone but i heard that drinking lots of green tea, especially right before the test helps "disguise" the toxins... or whatever they test for... i'm not very knowlageable about this however.... but i heard it from someone who was.
