"DCRs have been legally possible in Portugal for almost two decades but have not before been implemented. The overhaul of Portugal’s drug policy is summarized in the 1999 National Drug Strategy, which lays out a shift toward a less repressive drug policy and one centered on humanism, pragmatism, and public health. In 2001, both the decriminalization of low-level possession and use of illicit drugs and the Decree-law 183, regulating harm reduction responses, came into effect. DCRs are among the harm reduction measures detailed. However, the relevant law restricts DCR locations to areas that are not densely populated. The opening of a MDCR, which is part of a larger initiative by the city government and harm reduction NGOs to open 3 DCRs, two fixed and one mobile, allows service of the densely populated urban center. Only injection consumption is possible in the van due to limited space and lack of smoke extraction capacities."
