DMX’s health is once again a source of concern for those around him.

According to TMZ, an unspecified health condition has forced the legendary MC to cancel tour dates this week. Last night (Apr. 25), fans in Santa Ana, Calif. were told that Dark Man X was unable to perform due to a “medical emergency.” His upcoming concert in San Diego will also reportedly be postponed.

Insiders are concerned about the Yonkers rapper because of his recent behavior. Last week, he reportedly drank “heavily” at the Ruff Ryders reunion concert in Brooklyn. As a result, some critics said that he “bombed the show.”

During the concert, X discussed his troubles in a spoken word piece that he’s also shared in the past. “Whenever I went through something, it brought me closer to God,” he said. “I stayed in that something, so now I’m closer to God / But being closer is hard / Because the attacks get stronger / To fight and they last longer.”

According to the report, some also fear that X has relapsed in his ongoing fight with substance abuse. This was also a concern for many fans who viewed him in a video earlier this month, congratulating burgeoning rapper Quadir Lateef on his recent success. YouTube comments expressed sadness over his apparent troubles.

“hate the fact that drugs fucked X up smh..this dude is a legend regardless tho ,” said one viewer, while another added: “Sad to see X in this condition and I hope he gets better. ”

The Ruff Ryders leader has had an agonizing battle with these issues. Over the years, he’s been open about the struggles. In 2013, X spoke with Dr. Phil about his erratic past. When asked if he would change it in any way, the rapper responded: “I wouldn’t redo anything ’cause it got me right here, right where I’m at right now. I’m in a good place. No regrets.”

His health issues have continued to be worrisome. Just last year, he was reportedly hospitalized after being found unresponsive in a parking lot. While some worried that this might have been an overdose, X’s family claimed that it was related to an asthma attack.

DMX has not commented on his latest medical emergency.
