Thanks ya I was gonna stop smoking for a couple of days before it the test but I heard after you still need to pass and the tests are random, ostexcuseme:, lol ya it sucks so ill probably just limit my smoking til I get into a comfortable position and no longer have to worry, is there any key ingredient in those saliva detox bottles that you could find in maybe a mouthwash or some kind of cleansing device for your teeth, also does anyone know how long ahead of time you have to put that mouthwash detox for it to take effect because as I understand it, it stops your glands that produce spit and pauses them for a few hours but how long does this take to come into effect? Thank you very much for taking time to respond I am extremely grateful for your time and concern and cannot express how helpful this is.
