I took my polygraph today with a law enforcement agency somewhere.  I admitted to smoking marijuana a few times but denied ever using LSD.  I tried it twice in highschool, but I was told by my police friends not to admit to it because it is an automatic disqualifier.  I am not proud of lieing and I wish I did not have to, but I did.  Anyways, I read The Lie Behind the Lie Detector and learned to identfy control questions and apply countermeasures.  During the polygraph, I lied with reguard to being honest about my illegal drug use history, however, I was not questioned about it during the post test interrogation.  I was questioned about a couple of the control questions and I gave reasonable reason to why I reacted to them.  He went on to tell me that I passed the polygraph and that he would submit his report to backgrounds in a few days.  He was pleasent and wished me luck with the rest of the process.  Does this sound like I really passed or is there still a chance I might fail?  I read a few posts where people were told they passed but then found out later they failed or were inconclusive.  Any thoughts?   

Also, thanks George and Antipolygraph.org.  I passed my polygraph using countermeasures and by identfying controls.  I feel bad for lieing, however, I assume we all have skeletons in our closets.
