"GROSS: (Laughter) Right. So I thought this was really interesting. You had to get national security clearance for your job.
MASTROMONACO: Yeah.
GROSS: One of the questions you had to answer was a kind of detailed list of your drug use. And you'd smoked marijuana.
MASTROMONACO: Yes.
GROSS: You had to say how many times (laughter).
MASTROMONACO: Yes. That was...
GROSS: Yeah. So you handled it by saying unknown. How did you come to the conclusion that that would be your answer, an unknown number of times?
MASTROMONACO: Because - well, because I really feel strongly about not lying. And so when the FBI agent asked me for a number of times and she said, you know, 20? And I was like, no. She said, a hundred? I said, no. And then when she got up to 500, I was like, I'm not saying - I'm not giving you a number because who knows if they're going to go try and prove the number? So I just said, unknown. And apparently from her reaction, nobody had ever said that before.
GROSS: You write that you had to get randomly drug tested almost every month. Is that because you'd said unknown or does everybody have to do that?
MASTROMONACO: No. Most people get drug tested, like, once or twice that first year. But I was drug tested quite often because I was very forward-leaning about my drug use, very open-kimono, as we would say. And so, yeah, every - just about every month, you'd get an email that said, you know, you have 24 hours to show up for your test. And I would. And it was fine because I wasn't. So I had nothing to hide (laughter)."
