A new study finds troubling videos on YouTube could be a danger for people bent on injuring themselves.
Researchers say many of the videos are graphic and have live enactments of people harming themselves with razors or other sharp objects. Those videos then can serve as a how-to.
The author of the study found more than 5,000 videos on the video streaming site related to self-injury.
He says they also feature haunting music and rich imagery that may attract young self-injurers and trigger the behavior.
He says parents and mental health professionals should be aware of the postings and that the videos could be a problem.
