Hello i am new here and have found alot good sound advice on how to pass a urine drug test, however I just found out that the test i have to take on Friday is going to be a mouth swab test! I am a heavy smoker, i dont smoke large quantities but i do smoke pretty much everyday. One way im preping is by not smoking for the next three days prior to the test. I would like to know if anyone has any other ideas on how to pass on of these. The little I've gained from researching online is that it is good to take alot of mounthwash and brush your teeth sevral times before the test. And I've also read that many test only detect use of within 18-24 hours. If anyone can shed some light on any of these ideas and contribute some new ones it would be great! I really need this job to help pay for my school expenses. Thanks!
