Hey everyone, I am currently a 3/C mid at the academy. I am running into a dilemma with service selection and security clearance stuff. The service selection (submarines) I want to select requires a TS clearance. On my SF86 I admitted to full disclosure of prior marijuana experimentation, but thinking back to my DODMERB exam I did when I was a junior in high school I think I might have checked the "no" box for prior marijuana use. I don't remember if I was just nervous about it in front of parents/doctors, or why I didn't put it on there. I have and will continue to be honest and upfront about it on all other forms, but I just don't want a cross check of the dodmerb exam with my SF86 to prevent me from getting a TS clearance. My question is, will this cause a problem when applying for a TS clearance? Also, what should my course of action be? Should I ignore it, and if someone ever brings it up explain the discrepancy, or contact someone now? Any help/info would be greatly appreciated. Thanks.
