Used marijuana while cleared 5 years back

Hi,

I used weed while in a cleared role back in 2020 for a brief time. I left the cleared role in 2020. I did not self report. I rarely even used my access, but still I know I should have self reported then. I know, it was stupid. I haven’t smoked since then.

My clearance is still active somehow (CE?) and I was offered a job where they are now telling me they’d “like to hold my clearance for special projects in the future”. That changes things a bit.

I imagine once I start at the company and they pull in my clearance, I’ll have to do a new SF-86 since it’s been many years since I used the clearance, and I’ll be asked about drug use. I’d want to come clean and admit it. I’m sure that will fire off a bunch things and I’m worried they will revoke my clearance, even though it’s been 5+ years since I smoked anything, particularly because I used while in a cleared role. My record is fine otherwise - no financial issues, no arrests, no problems with the law or life otherwise. I’m hoping whole person concept would be considered but I know using while cleared is a huge red flag. Thoughts?
