I am getting polygraphed and have a few questions. I intend on telling the truth about past drug use which occured 15 years ago. I didn't tell anyone about this other than my recruiter when I joined. I did more tham Marijuanna and feel for sure that my clearence will be revoked. I plan on telling them that I know about polygraph(I have been reading your site), and that I know it is not scientific and that I know about countermeasures. What are the chances that I will ever get my clearence back? Will I be chaptered out of the army for my initial denials. When I filled out the ESPQ forms everything was concearning the last 7 years? Will the poly be the same? Thanks for your reply.
I don't know how big an issue your planned admissions will be. Your past drug use itself probably won't be a problem, but the revelation that you had concealed it might be. You may wish to check Security Clearances and National Security Information: Law and Procedures (http://antipolygraph.org/documents/security-clearances.pdf) (17.5 mb PDF), written by Sheldon I. Cohen for the Defense Personnel Security Research Center, for any relevant information.
I'm not certain what paperwork you'll need to complete, but I note that Standard Form 86 (Questionnaire for National Security Positions) includes a question (#24) about illegal drug use "since the age of 16 or in the last 7 years, whichever is shorter":

If indeed you tell your polygrapher what you've learned about polygraphy, would you be so kind as to let me know how your polygrapher responds?
Thanks for your response. I will certainly let you know what he says.
