In mathematics, there is a certain prestige in having a low Erdős number. Paul Erdős was famous for his (ab)use of amphetamines. The role which stimulants played in the sheer volume of papers he published over his life is up for debate.
"You shouldn't have mentioned the stuff about Benzedrine. It's not that you got it wrong. It's just that I don't want kids who are thinking about going into mathematics to think that they have to take drugs to succeed."
-Paul Erdős responding to the author of a 1987 Atlantic Monthly article profiling his work (as well as his use of benzedrine).
