A study led by the University of Delaware has found new evidence that being bullied in school may have lasting health consequences.

Using observational data collected from a sample of schoolchildren who were studied over several years, researchers reported that kids who were bullied more frequently when they were younger were more likely to use certain drugs by the time they were in high school.

The study, which was published this week in the journal Pediatrics, adds to existing research finding a link between nasty treatment by peers and drug use.
