Despite prevention efforts and even some deaths among teens, one dangerous activity is still around.
It's known as the "choking game."
Sam Houston State University recently released findings about the game among its students.
News 3 talks to one student and finds out what scared him straight.
"You feel real dizzy, real light-headed," said Marco Segura, a Sam Houston State University student.
It's called "the choking game," "pass out" or "the fainting game."
Segura said, "I would just be really cold and then you just feel real dizzy and I would just tell them to stop."
Marco Segura isn't the only college student who's played.
"A lot of people will have different reactions to it. Some people just fall down and look like they're sleeping for about 30 seconds, and some people go crazy. They'll start screaming and hitting," Segura added.
The Crime Victims' Institute at Sam Houston State University recently surveyed over 800 of it's students about the game.
The survey found nearly one out of every seven college students has played the choking game and 72 % admitted to playing more than once.
"You lean over for about 30 seconds and breathe in and out real fast," said Segura. "You stand straight up and you hold your breath and another person will just kind of like, grab your neck right here and squeeze, real tight."
The game involves deliberately cutting off blood flow to the brain, usually resulting in a "high."
Marco's last experience scared him so much, he hasn't done it since.
Segura said, "He just told me like hey, are you okay, like you hit your head on the fireplace...I was like, I'm fine, but I was like it really hurts, but, uh, that's the last time I'm going to do that."
According to the study, the average age for first timers is 14 years old.
We found plenty of videos online with much younger participants, like these two brothers.
Segura said, "If it was like my little brother and his friends doing it, I would definitely tell them to stop."
Several deaths have resulted from the game...and just like some illegal drugs, all it takes is one time.
Those in charge of the study suggest parents talk to their children about the game to see if they are aware of how dangerous it is.
