Well..I wouldn't do this but if I was in your position then I'd just quit for a little while. After a few drug tests she's gonna stop...I really doubt she's gonna put the time and money into testing you every week. Once she stops she will probably wait a couple weeks then try testing you again to catch you...after a couple months you should be able to start again. Just be more careful..don't wanna tip her off again. Cause you did something to make her search your room...something made her think she needed to.
