question:
Paragraph: "Ohio Sen. Rob Portman has been busy in Washington touting the Comprehensive Addiction Recovery Act in response to a shocking number of heroin overdoses in Ohio. The bill just passed in the Senate, 94-1. (Nebraska Sen. Ben Sasse was the sole ""nay,"" saying he believes that fighting addiction is a local issue.) Ohio ranks high on the list of states reeling from the national epidemic. In Montgomery County, which encompasses Dayton, Ohio, heroin-related deaths increased 225 percent between 2011 and 2015. Back in the 1970s, the heroin on U.S. streets was the ""black tar"" variety, and much of it came from southeast Asia. In 2010, 80 percent of the heroin in the world came from poppy fields in Afghanistan, according to the Office of National Drug Control Policy. So when Portman said that most of the heroin in America comes from Mexico’s border, we were skeptical. Portman, it turns out, has done his homework. The Drug Enforcement Administration’s National Drug Threat Assessment of 2015 says that Mexico is the primary supplier of heroin to the United States. ""Southeast Asia was once the dominant supplier of heroin in the United States, but Southeast Asian heroin is now rarely detected in U.S. markets,"" the report state. ""Mexico and, to a lesser extent, Colombia dominate the U.S. heroin market, because of their proximity, established transportation and distribution infrastructure, and ability to satisfy U.S. heroin demand."" The report also says that Mexican ""transnational criminal organizations,"" (the DEA’s term for drug-dealing gangs) ""pose the greatest criminal drug threat to the United States; no other group is currently positioned to challenge them."" The National Drug Threat report notes that Colombian gangs were traditionally the suppliers of wholesale cocaine and heroin to Mexican and Dominican groups. But cartels in Mexico are ramping up their roles on the supply side -- opium production in Mexico increased by 50 percent in 2014. Mexican labs also produce fentanyl, a synthetic painkiller that is 80 to 100 times stronger than morphine. Fentanyl is sometimes mixed with heroin or substituted for heroin, and the DEA reports more than 700 overdoses attributed to fentanyl between late 2013 and early 2015. Drugs get past the U.S. borders mostly ""by land, not by sea,"" said Homeland Security Secretary Jeh Johnson, in the same March 8 hearing with Portman. And a 2015 Washington Post series on the surge of heroin puts the border detection rate at a scant 1.5 percent. Smugglers’ creativity defies gravity: One successful bust came when agents caught two men flying a drone carrying 28 pounds of heroin from Mexico to California. Our ruling Portman said that heroin is coming to the United States primarily from Mexico. He hasn’t been studying drug facts for nothing." Claim: We understand that this heroin is primarily coming from Mexico, over the border.
answer:
Portman said that heroin is coming to the United States primarily from Mexico. He hasn’t been studying drug facts for nothing.


question:
Paragraph: The Advocate reports national and local politicians, law enforcement, health care experts and social services professionals attended a summit Tuesday in Baton Rouge hosted by Republican U.S. Sen. Bill Cassidy of Louisiana. They agreed providing mental health services to keep patients out of emergency rooms and jail is vital, but the speakers said it must be a bottom-up effort. Cynthia Kemp says she had worked toward better service in Arlington, Virginia, roughly a decade ago, raising about $800,000 for a jail diversion program and crisis intervention team. She’s now with the federal Substance Abuse and Mental Health Services Administration. Cassidy says communities need to leverage local money to collect federal grant assistance. ___ Information from: The Advocate, http://theadvocate.com Claim: Mental health care summit: Local officials must lead effort.
answer:
Federal officials say Louisiana leaders must take the lead in addressing mental health care for their own communities.


question:
Paragraph: The painstaking cleanup work inside Notre Dame itself was suspended last month for safety reasons, as activists and residents accused authorities of underestimating the threat of lead poisoning. Hundreds of tons of lead melted in the fire, which destroyed the cathedral’s metal and wood roof. Authorities have launched multiple lead prevention operations: cleaning up neighborhood schools, de-toxifying surrounding streets, and setting up a stricter new decontamination zone for experts working inside the cathedral. On Tuesday, police blocked several streets and a bridge around the monument, and high fences were erected to keep out Parisians and tourists alike. Experts plan to use two decontamination techniques for the surrounding neighborhoods, according to the culture ministry. One method will feature high pressure water jets with chemical agents. Another involves spreading a gel on public benches, street lights and other fixtures to absorb the lead, letting it dry for several days before removing it. The overall operation is expected to take about three weeks. Police union official Frederic Guillo said that after the current street-cleaning effort is over, authorities “will have to ask the question if we should extend the decontamination zone” to any other neighboring streets. Workers began decontaminating last week some Paris schools tested with unsafe levels of lead, and city authorities say all schools are expected to be decontaminated when children return to school in early September. Separately, work is continuing on the new decontamination zone for workers who’ve been clearing hazardous debris from inside Notre Dame, to ensure that their activities don’t generate any pollution outside the work zone. Authorities expect that to be ready by Aug. 19 and for cleanup work to resume. However that debris cleanup is still just a first step — to ready the cathedral for a massive, multimillion-euro reconstruction effort. French President Emmanuel Macron said he wanted Notre Dame rebuilt within five years but experts doubt that’s possible, and the belated lead prevention measures are further slowing down the process. Claim: Paris streets near Notre Dame to be decontaminated from lead.
answer:

Paris authorities shut down streets surrounding the Notre Dame Cathedral to decontaminate them Tuesday, after high levels of lead were registered in the area following the April blaze that damaged the landmark.
