When it first opened in 1986, the drugs museum at the defence ministry in Mexico City was a humble, one-room affair with few exhibits and even fewer visitors. Today, it is running out of space.

Three years after President Felipe Calderón declared an all-out war against Mexico's drugs cartels , and hundreds of seizures later, every inch of the museum's walls are covered with photographs and memorabilia of drugs busts, and its display cabinets are bursting with narco bling.
