I have recently applied for enlistment in the Air Force and have qualified for all the top tear jobs, most of which require a TS clearance. To my chagrin, as a teen I immersed myself in youth party culture and from the time I was 18 to 22yrs old, I lived as a degenerate where I made my living by selling narcotics. During this period I was well acquainted with cocaine, amphetamines, and hallucinogens, but was fortunate enough to avoid any confrontations with the law. Apart from a few traffic infractions, my criminal record is clean.
I have abstained from these substances since 2012 and have since done much to change the course of my life. The person I am today bears no relation to the one I was then and along with a great credit record, I have many references, both personal and professional, that will attest to my character.
My medical record is also sound, containing no record of drug abuse, clinical depression, or any other mental or physical health condition.
I fear that if I omit my personal history on the SF-86 it will come back on me negatively and so my question is, have I a prayer of being granted TS clearance given my past behavior?
