ST. PAUL (AP) -- Minnesota health officials are planning to release results of the state's first-ever survey on the use of e-cigarettes among students in middle and high school.

The results are being released Monday by the Minnesota Department of Health as part of the annual Minnesota Youth Tobacco Survey.

This was the first year in which the survey included a question about e-cigarettes, along with the usual questions about use of cigarettes, cigars and chewing tobacco.
