NETFLIX has added an extra warning to “13 Reasons Why.”

Mental health groups are among those to have raised concerns about how the show depicts suicide.

The series tells the story of an American high school student who takes her own life, leaving behind 13 cassette tapes for the 13 people she blames.

Netflix has added a warning card at the start of the show in addition to those before graphic scenes.

“13 Reasons Why” has been praised for raising awareness of the problems teenagers can face, including sexual assault and mental health.

But it has also generated controversy for showing the suicide of the central character, Hannah, in detail.

Mental health groups, including Australia’s National Youth Mental Health Foundation, have warned that the show risks “glamorizing” someone taking their own life.

And the New Zealand film board reclassified the series to stop under-18s watching it without a parent or guardian.

“13 Reasons Why” is rated 18 in Britain, which the British Board of Film Classification (BBFC) says is because of the sexual violence, strong bloody images and the suicide scene.
