Alright, I am a part of a college softball team and they are doing random drug tests for all the athletes at my school. This year they have opted for the salvia/oral fluids swab test. I am a pretty frequent pot smoker and I need to know if I should be worried or not. Well, I already am... but how long after I use can they detect it? Should I brush my teeth and use mouthwash before? I would just like someone's advice who has experience with this. Any and all info would be helpful.
