Gandelina Damião, 78, is permanently hunched, carrying her sorrow. She lost three children to heroin in the 1990s.
A quarter century ago, her cobblestone lane, up a grassy hill from Lisbon's Tagus River, was littered with syringes. She recalls having to search for her teenagers in graffitied stone buildings nearby, where they would shoot up.
"It was a huge blow," Damião says, pointing to framed photos on her wall of Paulo, Miguel and Liliana. "I was a good mother. I never gave them money for drugs. But I couldn't save them."
