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.
