A new report found that teens in rural areas and those with substance abuse issues or increased mental health risk factors were more likely to take part in the "choking game."

The dangerous practice involves choking each other to get a feeling of euphoria.

The Centers for Disease Control and Prevention in Atlanta on Thursday released the results of the survey done in Oregon.

It suggests that about one out of every 20 eighth-graders in the state has taken part.

More than a third of nearly 8,000 students from 114 Oregon schools who responded to the survey question about the choking game said they had heard about it.

And almost 3 percent of those responding said they had helped someone, while about 6 percent said they had participated themselves.
