Wow Friendowl, is that true??? Mouthswab can only detect within 8 hrs of use That would be cool. .. I've never had one of those tests and didn't know that. Nice to know that. I have always dealt with piss tests. All of them suck anyway.. Good luck to adfs... I know just how you feel. I'm also hoping I passed a test today for a great job. Much luck to you>>
