Thank goodness I found this site - it's too bad I haven't found it before my polygraph exam.  

I took the poly 1 week ago with the FBI.  Beforehand, the polygrapher went through the standard questions on my security form, and I answered all of them truthfully.  When he got to the drug usage part, I again responded truthfully and told him that I grew up religious (Mormon), and that I have never used any drugs in my life - as this is contrary to my religious beliefs.  The polygrapher nicely then told me that it is very  rare the people who come in here like myself who have never taken any drugs.  
When I finished with the exam, the polygrapher left me waiting in the room for a good 1/2 hour, then he finally came back.  He told me that I was being deceitful in my polygraph about the drug usage!!  I was not only stunned, but offended as this goes very contrary to my religious beliefs.  For crying out loud, I don't even do alchohol!   He kept on drilling me if there is anything that I would like to add to my application and that if I ommitted something.  I told him no- and that I was being extremely truthful.  However, no matter how many times I told him that his accusations are horrendous to even listen to, he did not seem to budge.  Finally, he told me that he would just "include a copy of your statement along with the polygraph" but that at this moment "it don't look too good".
I am not only stunned and outraged, but I feel like I now need psychological counseling because  a government agency is accusing me of something that goes very against my beliefs and something that I have NEVER done.   When I got back home, I got very sickened to my stomach, cried, and even threw up.  I have yet to hear of any results, although based on the "it don't look to good" comment, I know that they are going to fail me.
