The National Center on Addiction and Substance Abuse (CASA) released its annual National Survey of American Attitudes of Substance Abuse this morning. Most of the survey's findings aren't too surprising, but they are disturbing nonetheless. Among the findings: About two-thirds of high school students and twenty percent of middle school students report that drugs are kept, sold, or used on school grounds. A quarter of teens know a parent or guardian of a friend that uses marijuana. And for the first time, prescription drugs are easier for adolescents to obtain than alcohol. It should come as no surprise that the likeliest place for teens to get prescription drugs is in the home.

Taking a close look at federal survey data, the Family Research Council's Mapping America recently analyzed the significant influence of family structure on adolescent drug use.
