For contrarian takes on the steroid issue, see Eric's roundup, and also this piece from John Lott (yes, that John Lott) at Fox News.

I am sympathetic to these arguments. Listen, I don't believe Bonds for a minute when he says he didn't know what he was taking, and I don't believe Marion either.

But as I've said before, I think it's problematic to punish athletes for taking substances (like THG) that weren't illegal when they took them, especially considering that there's no clear or intelligible standard for determining which substances are banned and which aren't.
