I think there's an outsider perspective on the industry that is very invested in the notion that successful startup founders are generally chemically enhanced. I think that's false, and harmful for obvious reasons. When I ask startup people I know about it, I generally hear the same thing. But: limited visibility.

(I really don't care about adderall; I know a bunch of people with ADHD scripts, and they all seem to need it. I'm more concerned about stuff like modafanil.)
