A pair of studies involving more than 450 parents in Philadelphia that examined the effects of household smoking bans found that homes that imposed smoking bans were effective at reducing the number of cigarettes smoked at home. One study, in the American Journal of Public Health, found that smoking levels in a home did not determine whether a home imposed a ban; the other, in Preventive Medicine, profiled smoking policies in homes with children under the age of 13.
The proportion of U.S. adults identifying themselves as Independent has grown significantly over the last four presidential elections, rivaling both major parties, according to a national study by the Annenberg Public Policy Center that is being published in Presidential Studies Quarterly.
A national study of teenagers suggests that school drug testing did not deter them from starting to smoke tobacco or marijuana or drink alcohol. But in high schools that had a “positive school climate,” teens were less likely to start smoke cigarettes or marijuana, according to the study, in the January issue of the Journal of Studies on Alcohol and Drugs. The study compared the effectiveness over one year of school policies of student drug testing with a positive school climate.
A study in Addiction Biology of smokers’ brain activity has found that graphic anti-smoking warning labels that produce a strong emotional response are effective at deterring the urge to smoke, according to researchers at the Annenberg Public Policy Center and the Perelman School of Medicine at the University of Pennsylvania.
Nearly 90 percent of the top-grossing movies over a 25-year period show main characters acting violently, and in 77 percent of the movies those characters also engage in sex-, alcohol- or tobacco-related behavior, a new study has shown. The study published in Pediatrics, by researchers at the Annenberg Public Policy Center, found that more than half of the biggest PG-13 movies featured a main character acting violently and involved in either drinking, sexual behavior or smoking within a five-minute segment.
