What happened to just smokin some green?

BOISE, Idaho (AP) -- A 10-year-old boy was found dead, hanging from a tree, apparently killed while trying to get high by playing the "pass-out game," authorities said.

Dalton Eby may be the second Idaho child killed in recent months while playing a choking game, trying to cut off the oxygen supply to the brain to achieve a type of "high."

I did that once or twice in middle school.
Not sweet.

Edit for: Making myself pass out, not killing myself.
