I would like this to be deleted
In my opinion I would try to come clean as soon as you can. The question will be did you purposefully omit your drug use or did you simply forget. If a friend or relative is interviewed who knows about your drug use there is a potential for your undisclosed to become disclosed. Doubly so if you are required to take a poly for your clearance. Do note that there is always a chance of denial even if you do come clean. The longer it takes them to find out I believe the greater the chance of your denial. Honesty is everything.
Tell them you didn’t inhale. I’ve heard that works for certain people!
So I potentially screwed myself? It’s been a while since I applied.
