It is impossible to say at this point. A good parole officer does not expect perfection, but does expect honestly. I advise my clients that if they are asked to drop and they know they are dirty, they should tell the parole officer so before taking the UA. If this is your only transgression, I generally would not expect you to be taken into custody and/or revoked. I would, however, expect that your parole officer would start meeting with you and dropping you more frequently as a result.
