Question: Paragraph: Health and Human Services Secretary Alex Azar and Surgeon General Jerome Adams made the announcement, with Azar calling marijuana "a dangerous drug." Officials said President Donald Trump has donated $100,000 one-quarter of his annual government salary toward a digital campaign to raise awareness of the risks. Trump has forgone his official salary since taking office. The warning comes as legal marijuana has grown into a $10-billion industry in the U.S. with nearly two-thirds of states legalizing it, mainly for medical uses. Possessing small amounts of marijuana for adult recreational use is legal in 11 states and the District of Columbia, according to the National Conference of State Legislatures. The list includes California, Colorado, Michigan and Maine. Federal law still treats it as a controlled substance akin to opioids. Adams said science shows that marijuana is harmful to the developing brains of teenagers and to the human fetus. The drug has also gotten stronger, with a three-fold increase in the concentration of the active ingredient THC in cultivated plants over the last 20 years. "This ain't your mother's marijuana," Adams said. The American Medical Association said it strongly supports the government's effort, adding that it for some time it has been recommending against marijuana use by teens, pregnant women and women who are breastfeeding. The surgeon general said his advisory is a direct result of scientific research that runs counter to changing social mores. "Marijuana use is a risk to the developing brain," Adams said. "Over time there has been a change in attitudes about marijuana creating a false sense of security." While the White House has made the opioid epidemic a top policy and political priority, marijuana previously had not gotten such high-level attention. Federal officials say they fear the trend toward legalization may make it more enticing for teenagers to try marijuana. It's a commonly used drug among youths, they said, along with alcohol and e-cigarettes. No states allow recreational marijuana use by teens. States with medical marijuana programs, Illinois among them, generally allow use by minors with consent from a legal guardian and certification from a doctor. Adams said that for teens it carries a risk of affecting brain development, which continues in the 20s. Frequent marijuana use by teenagers is associated with changes in parts of the brain that are involved with attention, memory, decision-making and motivation. Among pregnant women, marijuana is the most commonly used illicit drug, with about 7% reporting they had used it within the past month in a 2017 study. Some women use it to help with morning sickness. The American College of Obstetricians and Gynecologists and the American Academy of Pediatrics advise women not to use marijuana during pregnancy, and to discontinue the drug if they find out they are pregnant. HHS Assistant Secretary for Health Brett Giroir said pregnant women taking marijuana to relieve morning sickness should stop. "If you have morning sickness, talk to your physician," said Giroir. "There are FDA-approved drugs to help with morning sickness. Taking marijuana for morning sickness has never been shown to be safe and effective." The government's National Institute on Drug Abuse is paying for several studies on marijuana use in pregnancy, including one involving women who have chosen to continue using the drug to treat morning sickness despite warnings. While some studies have suggested that marijuana may be harmful to the developing brain, the evidence isn't conclusive, explained NIDA Director Nora Volkow, who said she strongly supports the surgeon general's warning. "We cannot close our eyes and say this is not happening. It's happening," said Volkow. It would be a missed opportunity not to continue the research to find conclusive evidence on how the drug affects the fetus, she said. "My view is that the way that you change things is by providing evidence," she added. ___ Associated Press Medical Writer Lindsey Tanner in Chicago contributed to this article. Claim: 'This ain't your mother's marijuana,' surgeon general says.

Answer: Federal health officials issued a national warning Thursday against marijuana use by adolescents and pregnant women, as more states legalize the increasingly potent drug for medicinal and recreational use.

Question: Paragraph: Samoa declared a national emergency last month and mandated that all 200,000 people living on the South Pacific island nation get vaccinated. The government has closed all schools and banned children from public gatherings. In all, 53 people have died in the outbreak since late October, including one adult and two older teenagers. Most of those who have died have been babies and young infants, including 23 children aged less than 1 and 25 children aged between 1 and 4. The government said more than 1,100 people have been admitted to hospitals since the outbreak began and about 180 people remain hospitalized. Among those hospitalized are 19 children who are in critical condition. Samoan authorities believe the virus was first spread by a traveler from New Zealand. New Zealand Prime Minister Jacinda Ardern said Monday that her country was doing everything it could to help curb the epidemic, including sending more than 50 medical professionals and thousands of vaccines to Samoa. Other countries including Britain have also sent teams and supplies. Ardern said the natural curve of infection rates meant that "sometimes things can be worse before they are better." Figures from the World Health Organization and UNICEF indicate that fewer than 30% of Samoan infants were immunized last year. That low rate was exacerbated by a medical mishap that killed two babies who were administered a vaccine that had been incorrectly mixed, causing wider delays and distrust in the vaccination program. The government said about 33,000 people were vaccinated before last month and since then, another 58,000 people have been vaccinated. The World Health Organization has set a target of wiping out measles from most of the world by next year. It says the disease is entirely preventable thanks to a safe vaccine that has been in use since the 1960s, and that measles deaths worldwide decreased by 84% between 2000 and 2016 to about 90,000 annually thanks to better immunization. Claim: 50 children killed by measles in Samoa as outbreak worsens.

Answer: Samoa's government said Monday that another five children had died within the past day from a measles outbreak, bringing the death toll from the epidemic to more than 50 as authorities race to vaccinate the entire population.

Question: Paragraph: After its first two-day meeting in Geneva, the WHO panel of gene editing experts - which was established in December after a Chinese scientist said he had edited the genes of twin babies - said it had agreed a framework for setting future standards. It said a central registry of all human genome editing research was needed "in order to create an open and transparent database of ongoing work", and asked the WHO to start setting up such a registry immediately. "The committee will develop essential tools and guidance for all those working on this new technology to ensure maximum benefit and minimal risk to human health," Soumya Swamanathan, the WHO's chief scientist, said in a statement. A Chinese scientist last year claimed to have edited the genes of twin baby girls. News of the births prompted global condemnation, in part because it raised the ethical specter of so-called "designer babies" - in which embryos can be genetically modified to produce children with desirable traits. Top scientists and ethicists from seven countries called last week for a global moratorium on gene editing of human eggs, sperm or embryos that would result in such genetically-altered babies - saying this "could have permanent and possibly harmful effects on the species". The WHO panel's statement said any human gene editing work should be done for research only, should not be done in human clinical trials, and should be conducted transparently. "It is irresponsible at this time for anyone to proceed with clinical applications of human germline genome editing." The WHO's director-general, Tedros Adhanom Ghebreyesus, welcomed the panel's initial plans. "Gene editing holds incredible promise for health, but it also poses some risks, both ethically and medically," he said in a statement. The committee said it aims over the next two years to produce "a comprehensive governance framework" for national, local and international authorities to ensure human genome editing science progresses within agreed ethical boundaries. Claim: WHO panel calls for registry of all human gene editing research.

Answer:
It would be irresponsible for any scientist to conduct human gene-editing studies in people, and a central registry of research plans should be set up to ensure transparency, World Health Organization experts said on Tuesday.
