CHEYENNE, Wyo. (AP) — A study indicates fewer Wyoming junior high and high school students are using alcohol and tobacco.

The Wyoming Department of Health says 17 of the 19 participating counties saw substantial reductions in alcohol use and 15 of 19 showed substantial reductions in tobacco use.

The student survey provides detailed state- and county-level data on substance abuse issues, risk factors and protective factors affecting Wyoming youth.

Keith Hotle of the state Health Department says at the state level alcohol remains the most commonly reported used substance in all grade levels.

The 2012 survey was administered for the state Health Department by the University of Wyoming Survey and Analysis Center.
The agency uses the study to monitor changes in youth substance use trends.
