TS/SCI SF86 matter

Initiated my sf86 in April 2022, during my follow up interview with the investigator I disclosed a one time drug use from my college days (14years ago) that I didn’t list on the sf86. I’ve also done previous sf86s over the years for other positions which that drug use was never listed. Given it has been 10 months and I have yet to be granted my clearance, do you think that omission will disqualify me on the subject of “personal conduct” or “untrustworthiness”?
