Is Mexico's defense minister a crack head?

Ciro Gómez Leyva dedicates his column in today's Milenio to the affaire Calderón ivrogne (OK, I liked the rhyming bit), and notes,

"If tomorrow someone invents that the Secretary of Defense is addicted to crack and rat poison, would it be his duty to go out and reject this lie because he has a hundred thousand soldiers under his command? What are we talking about here?"

For the record, I don't think Mexico's defense minister is a crack head and rat poison addict.

But he hasn't confirmed that he isn't.
