A former roommate from college asked if I would have any issues being a reference for his security clearance process. I've been trying to google/find out what it entails but wasn't able to find much online. If my post violates any rules let me know and I'll take it down.
Essentially, a former roommate from college (graduated 4 years ago) asked if they could use me as a reference of some sort. I'm not sure if it's as a personal reference or 'I lived with this person at some point in time' type deal, except it's for a 'Secret' clearance. The issue is that he and I did drugs several (4-5) times in the past after graduating, but nothing in the last few years. Now, he said he's got to list the drugs and my name on the form he has to fill out and that if I was contacted by someone, to tell the truth, but I'm worried about getting myself in trouble.
So, the info I'm looking for is: Should I expect to definitely be contacted? What sort of questions will they ask me about him? Will I get in trouble for him listing me? What happens he says one thing and I say another? (E.g. He says we did drugs 5 times, but I only remember 4?) Will they ask for exact dates? What if I say the wrong date since it was a few years go? Will the investigator contact my employer? Will they ask me to give names of other people I've done them with? Could the info I give be used 'against' me (I know that's not the right term) if I were to apply for a clearance later on?
Any help/info is much appreciated
