I've googled all day and found a million ways to better your chances of passing a saliva drug test but not one that has passed everytime someone has used that method. I know there's nothing that is 100 percent sure but I also know there has to be some type of special mouthwash or home remedy that hasn't failed anyone! I need to take this test either wed or thur and stopped smoking this afternoon as soon as I found out! I smoke several times a day! What can I do or buy on top of not smoking to help me be more sure that I'm gonna pass this test? Thanks in advance for your advice!
