Yesterday, the Mitchell Report, on steroid usage in baseball, was released. A large number of players were named as users or potential users.
The media coverage of this has routinely mentioned that amphetamines seem to be more common in baseball than steroids; one source I ran into said it's believed that half of baseball players use amphetamines regularly.
Now, when I think of amphetamines, I think of Paul Erdos, and the following story: Ron Graham bet Erdos that he couldn't quit amphetamines for a month, cold turkey. Erdos did. Graham paid up. Erdos said "you've set mathematics back a month".
As far as I know, we mathematicians don't have a drug problem. (Unless you count coffee. I'll freely admit I have a coffee problem.) But I don't think that anybody would say that Erdos should be stripped of any award he won because he was using drugs. The difference is that in sports, the players are competing against each other; thus a level playing field is essential. But in mathematics, we like to believe that we are not competing against each other but cooperating to discover truth; thus we may gladly accept all the chemical help we can get.
