Dwayne 'the Rock' Johnson claims Phoenix is top for meth use at WWE SmackDown. Is he right?

WWE SmackDown came to Glendale on Friday and Dwayne "The Rock" Johnson made an appearance.

Johnson entered Desert Diamond Arena to boos, but he went on to roast neighboring Phoenix. He went on to say that Phoenix was the "No. 1 city in America for cocaine and meth use."

"Finally your life has meaning. Because finally you cactus-loving crackheads finally have something worth shooting in your veins," he concluded.

Johnson, who rose to WWE stardom in the 1990s and 2000s, returned to wrestling in February, where he indicated he wanted to fight champion Roman Reigns at Wrestlemania in April.

While Reigns will face Cody Rhodes at the event, Johnson has continued to make appearances at WWE Friday Night SmackDown events. He appeared onstage in Salt Lake City on Feb. 16 where he lambasted "the largest gathering of trailer park trash The Rock has ever seen."

While the Rock said he "did a little bit of research" about Phoenix, is he right? Here's what to know about methamphetamine and cocaine use in Phoenix.

What did the Rock say about Phoenix at Smackdown?

"The Rock has got some news you're going to like. The Rock has got some news you might even be proud of. Apparently, Glendale is 10 miles away from Phoenix. Assuming the answer is yes, but are there a lot of people from Phoenix here tonight?" he said as the crowd cheered loudly.

"I knew it because that would make a lot of sense," he went on to say. "The Rock did a little bit of research and this is the truth. This is a fact. The No. 1 city in America for cocaine and meth use is Phoenix, Arizona."

At that point, the crowd at Desert Diamond Arena, which he called "a crack den with popcorn," got even louder as the WWE superstar continued.

"Here's what that means: Finally your life has meaning. Because finally you cactus-loving crackheads finally have something worth shooting in your veins as you sit and you look at greatness. Finally the Rock has come back to Arizona."
