1. Yes. I smoked every day when they tested me I dipped my fingers in bleach and pissed on my fingers and into the cup.
2. Once a month or whenever they suspect you of it thats on a drug charge they probobly wont even test you on another charge but im not for shore.
3.Umm idk. Dont smoke. I mean just stay clean as long as your on probation that the only shore fire way to pass. yeah if it is not a drug charge they will only test you once and if you pass they wont test you again.
