When I originally filled out the SF86 I had only recalled using marijuana experimentally once in high school, recently I remembered another instance in High school. It was more than once but less then 3 times in highschool and then I realized it was dumb and never continued. I currently have a secret clearance and will require a TS for my job. Will this cause any issues? Is it likely to come up? And what would be the way to handle this?
