In the mountains of Mexico's tropical sierra, an ever-growing expanse of pink poppy flowers has pushed prices so low for opium paste, the gummy raw ingredient of heroin, that farmer Santiago Sanchez worries how he will feed and clothe his family. The area of Mexico that illegally farms opium poppies grew by more than one-fifth last year, to an area the size of Philadelphia, according to a U.N.-backed study published in November. That, along with a trend toward mixing synthetic opiate fentanyl in Mexico's tarry black heroin, has slashed what criminal gangs pay farmers like Sanchez for a kilo of opium. Now, Sanchez earns about $260 per kilo, a fifth of the average price two years ago. While Mexico's top drug traffickers still make billions of dollars supplying U.S. addicts, at the bottom of the supply chain, the villagers are hardly surviving.

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.
