Past Marijuana and Getting a Security Clearance

Question: Will Marijuana use in the past keep me from getting a security clearance?

Answer: Previous use of marijuana might preclude the granting of a security clearance, or it might not. It depends, in large part, on the exact circumstances of the use (police record, amount used, how long ago, ect.) In general, the security clearance investigation is looking for evidence of untrustworthyness. For details, see our feature article, Security Clearance Secrets.

Security clearances, aside, previous use of drugs, or criminal history may make one ineligible to apply for certain jobs. For details, see our complete listing of enlisted job descriptions & qualification standards:
