Wow i have a test in 3 days and i will be 3 weeks clean too. I did a lot of cardio for the past 2.5 weeks, stopping today since my test is soo close and i dont want any THC to be released. I took 5 home Tests, and came up negative for all. But now i am scared after reading this. How faint were your lines? Check out my thread, were they as faint as mine? http://boards.cannabis.com/drug-test...-included.html
