I've been researching going 35N thru BEAR. I know I need at least TS clearance interim, I already hold a Secret, prior to being accepted into training and during AIT a successful TS followed by a counter intel investigation maybe even polygraph. My only concern regarding these probes and the SF86 is that I used marijuana before I joined. The useage may have been frequent enough to be considered "regular". The requirements for 35N mentions nothing against past useage, unlike 35L&F but, will this bar me from TS or 35N?
