Miley Cyrus is trying stop a new trend on the Internet that involves Justin Bieber fans mutilating their bodies after seeing pics of him smoking pot.

The hashtag #cut4bieber has become the top U.S. trend on Twitter after people started posting pics of bleeding arms. It's apparently "cutting" by disappointed fans looking to pressure Justin into giving up his pot habit.

Someone even started a website encouraging Bieber fans to cut themselves and post pics until he gives up marijuana for good.

But Miley Cyrus Tweeted: "#cut4bieber? Cutting is NOT something to joke about. There are people who are actually suffering from self-harm, this is so disrespectful."

No word on if Justin knows about the situation.
