WEST LAFAYETTE, Ind., Aug. 6 (UPI) -- U.S. adolescents are more likely to smoke if their parents smoke or if an older sibling smokes, U.S. researchers say.
Mike Vuolo of Purdue University in Indiana and Jeremy Staff of Pennsylvania State University analyzed data from 214 parents and 314 children ages 11 and older. Eight percent of the children of non-smoking parents smoked in the last year.
