Picked the wrong week to quit amphetamines.

"The one thing I wanted to make sure was explained is, no steroids," Cameron told AM 1090, the Padres' flagship radio station. "I never took nothing like that before in my life. That would be 50 games, and that would affect me a whole lot more."

Further proof it wasn't steroids: he only got 25 games.  But it's also his second positive test.  Note to self: don't get advice from Neifi Perez's trainer.
