The study to be published on Wednesday in the Journal of Neuroscience differs from many other pot-related research projects that are focused on chronic, heavy users of cannabis. The collaborative effort between Northwestern University's medical school, Massachusetts General Hospital and Harvard Medical School showed a direct correlation between the number of times users smoked and abnormalities in the brain. "What we're seeing is changes in people who are 18 to 25 in core brain regions that you never, ever want to fool around with," said co-senior study author Dr. Hans Beiter, professor of psychiatry and behavioral sciences at Northwestern University. In particular, the study identified changes to the nucleus accumbens and the nucleus amygdala, regions of the brain that are key to regulating emotion and motivation, in marijuana users who smoke between one and seven joints a week. The researchers found changes to the volume, shape and density of those brain regions. But more studies are needed to determine how those changes may have long-term consequences and whether they can be fixed with abstinence, Beiter said. "Our hypothesis from this early work is that these changes may be an early sign of what later becomes amotivation, where people aren't focused on their goals," he said. The study, which was funded in part by the National Institute on Drug Abuse and the White House Office of National Drug Control Policy, comes as access to pot is expanding following 2012 votes in Washington state and Colorado to legalize its recreational use. The drug remains illegal under federal law. Medical pot is allowed in 20 U.S. states. Pot legalization advocates make the argument that marijuana is safer than alcohol a central part of their campaigns. Other research has found drinking alcohol alters the brain, Beiter said. But while researchers do not know exactly how the mental rewiring seen in pot users affects their lives, the study shows it physically changes the brain in ways that differ from drinking, he said. This latest study fits with other research showing marijuana use has significant effects on young people because their brains are still developing, and Beiter said he has become convinced that marijuana should only be used by people under 30 if they need it to manage pain from a terminal illness.

After complaints about taste and costs, the Trump administration rolled back a rule that required foods like pasta and bread be made with whole grains. The cafeteria directors who lobbied for the change say they just want greater flexibility to serve foods like white bread which are more processed and have less fiber when whole grains don't work. In Vermont, the relaxed rule means white rice will be served with beans again. In Oregon, macaroni and cheese may return. And in South Dakota, students may notice a change with their soup. "The staff asked right away, 'Oh my God, can we go back to the other saltines?'" said Gay Anderson, a school lunch director and president of the School Nutrition Association, which represents cafeteria operators and suppliers like Domino's and Kellogg. The rollback addresses rules on grains, milk and salt championed by former first lady Michelle Obama. Since 2014, schools had been required to serve only whole grain versions of food as part of the national school lunch program, a critical source of free and reduced-price meals for millions of children. The idea is that whole grains would be more nourishing and help cultivate healthy habits amid alarming obesity rates . The Center for Science in the Public Interest, which is among the parties suing over the rollback, notes the standards were based on the government's own dietary guidelines and that most schools were successfully meeting them. But cafeteria operators said costs were higher, cooking was more difficult and students were throwing away more food. The School Nutrition Association said it's more important that children who rely on the lunches eat something, and that the rule ignored cultural preferences, such as for flour tortillas in the Southwest or for white rice among Asian students. To ease the transition to whole grains, the U.S. Department of Agriculture let schools apply for temporary waivers to serve select dishes that didn't meet the whole-grain rule. For the last school year, it said about 20 percent of districts asked permission to serve refined grains that are enriched to add back some nutrients. Among the frequently waived foods were pasta , pizza , tortillas and biscuits , which one Georgia lunch official joked affects the "tests scores of rednecks ," according to records obtained by The Associated Press from state agencies. Other waived foods included beignets, cinnamon rolls, corn dogs, sugar cookies and Pop Tarts. One district requested a waiver for croissants because it said students don't like the whole-grain version. "Plus they are 20 cents more per serving," the district said. Then in December, Agriculture Secretary Sonny Perdue said the USDA was going back to the old standard: At least half of grain foods must be rich in whole grains. The agency said that does away with the red tape of making schools get waivers, and gives schools more flexibility to offer wholesome meals that also reduce food waste. Whitney Ellersick, a school lunch director in Portland, Oregon, said the change means her district will no longer need a waiver for its lasagna. But she was surprised by the extent of the rollback. "I was a little shocked to see it go to 50 percent," Ellersick said. The Center for Science in the Public Interest said the USDA's rollback may be halting progress made by schools, which could be tempted to bring back more refined grains that cost less or are easier to make. Already, the group notes the USDA defines "whole grain rich" as being half whole grain, meaning there's built-in wiggle room to make bread and pasta students won't mind. Bettina Elias Siegel of The Lunch Tray website also noted a recent USDA report that found that "plate waste" was comparable before and after the rules were implemented in 2014, undermining arguments they were prompting students to throw away more food. The report also found that students took advantage of lunches more often in schools with healthier lunches. The American Heart Association likewise criticized the decision to relax the rules and called on school districts to stick to the previous standards, which also included stricter rules on salt and milk. Among the districts that plan to do so is Boston, where fifth grader Trinity Wilson likes the brown rice. She said it's is healthier than white rice. "I know that because my mom told me," Wilson said. But some school lunch officials say the rollback could help smaller districts that don't have access to as many products. In Arkansas, students in the Magnet Cove district accepted whole-grain Pop Tarts and other changes, officials say, but still prefer the old noodles, biscuits and rolls. "They're tastier, softer and fluffier," said Danny Thomas, the district's superintendent. In Burlington, Vermont, white rice and beans can return to menus. Doug Davis, the district's food director and incoming president of the School Nutrition Association, said it's a healthy dish that students will actually eat. To avoid buying two types of rice, Davis said white rice will likely also be used in stir fries and soups. He plans to stick mostly to whole grains, but he appreciates not having to. Whole-grain pasta isn't ideal for mac and cheese, Davis noted. "Would we make a change on that? I don't know," he said. ____ Follow Candice Choi at www.twitter.com/candicechoi ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education.

EpiPens deliver potentially lifesaving doses of the generic drug epinephrine, via an automatic injector that a patient or caregiver can administer in the event of severe allergic reaction. "We are shipping product. Currently there is no shortage in the U.S.," said Steve Danehy, a spokesman for Pfizer Inc (PFE.N), which produces the global supply of EpiPens for Mylan out of a single facility near St. Louis, Missouri. Mylan is in charge of managing allocation of the EpiPen supply, Danehy said in an email to Reuters. It was not immediately clear why Canada and the UK would be subject to a shortage at this time. A Mylan spokeswoman was not available for comment. Mylan's EpiPen sales practices in the United States sparked public outrage in 2016 as consumers saw the price for a pack of two auto-injectors rise sixfold to $600 in less than a decade, making the devices unaffordable for a growing number of families. Since then, the company has launched a generic version of EpiPen for half the price, though the U.S. market is still the most lucrative. Meridian Medical Technologies Inc, the unit of Pfizer that manufactures EpiPens, has been hit by a series of manufacturing problems. In March 2017, Mylan recalled tens of thousands of devices after complaints that some had failed to activate. In September, Meridian received a warning letter from the U.S. Food and Drug Administration. The FDA said Meridian had failed to thoroughly investigate product failures, including EpiPen products that were associated with patient deaths and severe illnesses. It said the company failed to take corrective actions until FDA's inspection. At the time, Mylan said it did not anticipate any impact on EpiPen supply based on the warning letter. But on Thursday, Pfizer Canada said it was "experiencing supply constraints" for EpiPens used by both adults and children "due to delays at the manufacturing facility," as well as problems in sourcing a component for the device from an outside supplier. There are no alternatives on the market in Canada, federal health officials there said. They advised patients and caregivers to use expired EpiPens in an emergency if they have nothing else on hand, and then call 911. "Pfizer understands and regrets the challenges that these ongoing supply constraints pose to patients and the healthcare community," the company said in a statement on its website. On Friday, the UK website for EpiPen notified consumers of "intermittent supply constraints" for the adult injector. It said the next shipment to EpiPen's distributor in the country was expected toward the end of April. Mylan's revenue from EpiPen dropped sharply over the last year due to increased competition, the launch of its own cheaper generic and higher rebates that it has had to pay to as a result of a settlement for overcharging the U.S. government.
