"Drug consumption rooms (DCR) are in place for more than three decades in Europe and have been proven to be effective as a public health response. However, their implementation remains slow and controversial in many countries. In Portugal, despite being legal since 2001, the first DCR only came into reality in 2019 by the initiative of the City Council of Lisbon."
