According to Milenio, an undersecretary of health said that 80 percent of Mexico's prisoners are addicted to one drug or another. Quite a number, but I'm not sure about that stat; 80 percent of the convict population is addicted, in a country where drug use is not particularly prevalent? Not likely. However, the idea that addicted criminals should be treated in a public health context rather than sent to prison is certainly something worth considering.
Not sure how directly this comment reflects the views of José Ángel Córdova (though the comment was made in his home state of Guanajuato, where he's been rumored as a possible gubernatorial candidate), but I second Aguachile's comments here.
