Fewer students are smoking cigarettes or drinking alcohol, according to a recent survey of kids in Washington state.
At the same time, a large number of students seriously considered suicide in the past year.
The number of secondary school students who believe using marijuana is risky dropped to the lowest level since the state started collecting data.
The Healthy Youth Survey is taken every two years by students in grades 6, 8, 10, and 12 in more than 1,000 public schools in Washington. More than 200,000 youth took part in the survey in October 2012 by answering a wide variety of questions about their health and health behaviors. All responses were voluntary and anonymous.
