I need info on how long drugs are detectable in a cotton saliva swab test. A list of what stays for how long would be great too, and if you have any links or sources I would love you for it. Just asking because I just had my first meeting with my PO, drinking a gallon of water beforehand to piss straight poland spring water but then she pulls out the swab test and I know I'm fucked. So I tested dirty today due to not being prepared but would like the info now that I know whats good. Thanks in advance, continue to fool the system as much as you can.
