The Youth Risk Behavior Survey, produced by the Centers for Disease Control and conducted every two years, assesses health risk behaviors that contribute to some of the leading causes of morbidity and mortality in youth.  There are few surprises. CMS noted that cigarette and inhalant use is down (just by one percent). However, high schoolers’ computer usage for non-school work is up.

In 2009, 26 percent answered yes. Click  here for the PDF of all high school the results. For middle school results, click here.
