I am currently starting a new position which will require a Q clearance in the future. I was looking through Form86 and am not sure how to answer the question "Have you ever been charged with or convicted of any offense related to alcohol or drugs?"
In the summer of 2001 I was caught with 0.5 grams of pot at the Canadian border (entering Canada from US). The Canadian border agents simply confiscated the pot and let me continue on into Canada, no fine or anything. As far as I know I was not charged with anything, though I am sure that the incident filed somewhere in the Canadian legal system. How far does a Q clearance investigation go, will they check Canadian records? I want to answer honestly but I don't want to volunteer any extra information.
After getting caught I decided that my causal use was just not worth it and have never smoked any since.
Any advice?
