The U.S. Supreme Court is seen after justices ruled that potentially hundreds of low-level crack cocaine offenders cannot benefit under a 2018 federal law that reduced certain prison sentences in part to address racial disparities detrimental to Black defendants, in Washington, U.S., June 14, 2021.

Fabiana Silva called the streets of Sao Paulo home for 16 years as one of hundreds of people trapped in cracolandia, the open-air drug markets in South America's biggest city. Now the street has become a livelihood for Silva, who has kicked an addiction to crack cocaine and moved into an informal two-story dwelling in a nearby slum. Silva, 38, pulls her bright purple cart by hand through Sao Paulo, piling it high with more than 400 kg of recyclables picked from refuse to earn roughly 100 reais ($32) per day - the only money she earns to support three children. "The street today puts food on my table," she said. REUTERS/Nacho Doce SEARCH "NACHO RECYCLING" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES. TPX IMAGES OF THE DAY.

Samples of pipes for crack cocaine and methamphetamine use sit inside the jacket pocket of Shilo Murphy, executive director of the People's Harm Reduction Alliance, the nation's largest needle-exchange program, in Seattle, Washington April 30, 2015. The People's Harm Reduction Alliance launched its free meth pipe program, which is pioneering but illegal, in March after learning from its own survey that 80 percent of area meth users would be less likely to inject drugs if given access to pipes. The theory behind the Alliance's handout program is that giving meth pipes to drug users may steer some away from needles, which are far riskier than smoking, especially if the user is sharing with another person infected with HIV or hepatitis C. There is little scientific evidence to support that claim, but the Alliance, a privately funded needle-swap group run by drug users, said it has distributed more than 1,000 pipes in Seattle in a matter of weeks and could expand to other cities in Washington state and Oregon. Opponents say giving away meth pipes discourages quitting while wasting resources on an untested scheme that will not solve a city-wide health problem. Picture taken April 30, 2015.
