I recently had a pre-employment polygraph for an intelligence/security organization. I was very naive of this process beforehand, and just thought the best approach was honesty. Due to my ignorance of this procedure, I made a few admissions during the "pre-test" phase, one of which was potentially very damaging to my chances. Specifically, I admitted to a use of marijuana about two years ago, which I had not indicated on paperwork. Probably the worst thing about this was that I already have a security clearance required by my present job, and had it when I had my lapse in judgement.

My concern is not so much being considered further for employment with the organization as it is that I could potentially lose my security clearance for this admission that the polygrapher duped out of me because of my ignorance.

I was wondering about this: Suppose I call the organization in question and rescind my employment application before the adjudicator gets the chance to shut me down? What effect might that have on the potential consequences of my situation?
