Theres a "Drug Testing" section specifically for this type of question. Why post it in "Recreational"? This category is for stupid questions like "Man, I was so high last nite, and then..."

but I actually can answer the question.....I smoke everyday and for the last job I got, I stayed clean from FRIDAY Night - Monday at around 3PM is when I took the test. I drank ALOT of water in between those 3 days, and right before the test I drank a bottle of those drinks to clear your toxins out. I am a big guy with a high tolerance so I went with the 50 dollar bottle, and it worked fine for me. Just take it 1 hour before, drink lots of water, pee once or twice, and your good to go. :thumbsup:
