I was wondering the same thing being that i also have a mouth swab on tuesday. i have found looking through the forums prior to asking, that the issue has been brought up several times before and that it has been confirmed by someone known as fakeboobsrule (FBR) who apparently really knows his shit when it comes to drug tests, is that 96 hours (4 days) is the maximum amount of time it is traceable in saliva. even 3 days is usually just fine from what others have said as well. so just set the pipe down for a few days and you will be all good :thumbsup:
