There was a change in the wording of regarding drug use after receiving a security clearance. The old (2005) version of the Adjudicative Guidelines (AG) said at 25(g) “any illegal drug use after being granted a security clearance.” The new 2017 version says at 25(f) “any illegal drug use while granted access to classified information or holding a sensitive position.” Under the old AG your recent MJ use would be a potentially disqualify condition under 25(g). Your recent MJ use is not a potentially disqualifying condition under 25(f) of the new AG; however, your recent MJ use will be view as potentially disqualifying under 25(a) “any substance misuse” just like everyone else. The case you cited was adjudicated before June 2017 when the new AG was implemented.
