I had a different experience, when I was in front of a Defense Investigative Service agent, filling out my forms in 1989, for a TOP SECRET/SCI clearance required for the job I had accepted working for the Defense Information Systems Agency, in the basement of the Pentagon. I told him that I had smoked marijuana (I was still studying for my degree at University), and that a number of my friends also smoked, and they were the reason why I smoked (peer pressure). I also informed them of the damage I had seen done to our friendships inside the group, as certain friends had gotten into fights with other friends over the money needed to buy the stuff. I also gave names and contact details of various friends in that group. I informed those friends that they would be interviewed, and to just tell the agent the truth -- as I had done. They all reported back that they had been interviewed, and told him the truth. But they also didn't give me any more details, and I was fine with that. What was a little strange about that whole clearance investigation process was that the agent also wanted to know the addresses of my grand parents, in addition to the fifteen year history of everywhere I had lived myself. And about a month later, one of my grandmothers got a visit from a Secret Service agent. Turns out that the Defense Investigative Service didn't have any agents in that area, so they farmed out that work to the local Secret Service office. So, yes -- I did smoke, and I did inhale. And all the agents cared about was whether I was trying to hide something like this, because that would mean I would be vulnerable to blackmail over those events.
