Failed Full Scope Poly

I currently hold a security clearance, and based on my current role, I was allowed to start the position but needed a Full Scope (FS) polygraph to maintain it. During the polygraph process, I disclosed a one-time drug use from before I received my clearance, which I had not previously noted on my SF-86. When asked if this occurred while I held a clearance, I clarified that it did not. I was allowed to proceed with the polygraph, though additional questions were added as part of the test. After the usual procedure of leaving the room and returning, the examiner asked if I was withholding anything else, to which I answered no. Despite my response, I did not pass, and she informed me that I would need to retake the test. It’s been almost a week without any updates, but I’ve continued working as usual. Should I be concerned about my clearance status, or is it likely to be revoked?

Maybe. You admitted to not being truthful on your SF-86
