Likely orthogonal, but it wouldn't surprise me if Brian Cuban's story and battles against substance abuse served as an additional motivator.

Brian's pretty public about it. Wrote a whole (and great) book, "The Addicted Lawyer," telling his story in depth. Granted there's nothing Big Pharma in there from what I remember, but I could see me being motivated in a similar direction if a sibling had to fight that fight.
