PROBLEM: 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.

SOLUTION: Casual pot use causes brain abnormalities in the young: study.

PROBLEM: The Arkansas Department of Health issued the public health directive in a Nov. 22 letter that stated students without at least two doses of measles, mumps and rubella vaccine either be vaccinated immediately or be barred from classrooms and school activities for at least 26 days. Brothers Shiloh Isaiah and Benjamin Andrew Bemis asked the Washington County Circuit to issue a temporary injunction, arguing “that the University of Arkansas failed to recognize and uphold our philosophical beliefs as enrolled students -- beliefs which include the choice to abstain from vaccinations.”   In a one-sentence order, Judge Doug Martin on Tuesday denied their request to be allowed to return to their classes without getting the vaccinations. Martin’s order didn’t explain the reason for the decision. Shiloh Bemis, 21, told the Arkansas Democrat-Gazette that he’s disappointed in the court’s order. “On a larger level, we are taking issue with the fact that we don’t think we’ve quite been given a choice that fully takes into account what we believe our rights to be,” the third-year architecture student from Fayetteville said. Benjamin Bemis didn’t respond to the Democrat-Gazette’s request for comment. State law requires vaccinations for students, but it also allows exemptions for medical, religious or philosophical reasons. But the state Health Department said even exempted students must heed the public health directive. “Even if they have an exemption, they still are supposed to be excluded from class and activities, since they are much more susceptible to getting the infection,” said Dr. Joel Tumlison, a physician specialist in the health department’s outbreak response team. “For any student, whether simply undervaccinated or with an exemption, if they change their mind and get the vaccine, they can then return to class/activities.” University spokesman Mark Rushing said the school will continue to follow the health department’s instructions. The university has had 26 mumps cases since September, according to health officials. As of last week, 168 students lacked the required vaccinations to attend classes, UA spokesman Zac Brown said.

SOLUTION: Arkansas judge denies students’ appeal to vaccination policy.

PROBLEM: A 34-year-old woman from Loudi city in the central province of Hunan confessed to poisoning the yoghurt drink before delivering to the students, Xinhua said on Saturday. It said the woman was suspected to be suffering from a mental disorder. Three children were in serious condition but their lives were not in danger, Xinhua said. Investigations were going on. There have been several attacks on schools in China in recent years while at the same time, food safety has become a contentious issue with a rising number of food-poisoning cases due in part to lax safety standards at small factories.

SOLUTION:
Nineteen students sick in China from poisoned yoghurt.
