If you have a middle school student in your life -- chances are, they have heard of, or even played the choking game.
But have you?
A new study just released by the Oregon Health Authority reveals six percent of eighth graders statewide have participated in this ever growing trend.
Teens choke themselves with their hands or a rope or belt, to reach a euphoric high, when blood flow returns to the brain.
Officials say more than 5,000 eighth-graders completed the survey in 2009-- and more than 90% answered the choking game questions.
Reports reveal the game appeals to teens because of one popular form of technology.
The warning signs: Neck marks, bloodshot eyes, pinpoint bleeding spots under the skin on the face, or disorientation after spending time alone.
Researchers say talking to teens in your life about the risks will help.
