This is how: I smoked and didn't know I would be tested. I brushed teeth and washed mouth with listerine with alcohol. Go to work and when I took swab I bit down on it the whole time so it didn't touch cheek or gums. Out five minutes later. This was a labcorp test. Easy
yeah man i mouthwash works really well for those tests, how dope is that? hahahahahah good shit man stay frosty
