So here is the situation. I have a few opportunities for employment, each of which requires me to pass a polygraph test. I have tried marijuana(dozen times probably), cocaine(like 3 or 4 times) and opium once. It has been 3 or 4 years since I have touched any sort of drug, and I will never touch them again. The question is, do I go into the exam and be 100% honest about my drug use or will that automatically disqualify me from getting a security clearance? Should I go in and absolutely deny everything and just hope for the best? Other than that, I have absolutely nothing in my past that I am ashamed of or that could possibly hurt me.

To be completely honest, the polygraph absolutely mortifies me, especially after I have read this website. The last thing I want is to be kept from clearances(I DO have a secret level clearance now) because i did a few stupid things early in college.
