Ja Rule Says Hip Hop's Influencing Ja Morant's Poor Decisions, 'That Ain't The Way'

Patrick Beverley's right -- at least, that's what Ja Rule is saying, telling TMZ Sports he believes Ja Morant is absolutely being poorly influenced by hip hop.

The Chicago Bulls guard made waves earlier this week by sayin' he believed rap and the culture surrounding it are contributing to Morant's recent missteps ... and when we got Ja Rule out at LAX this week, he couldn't have agreed more.

He said growing up he was influenced to smoke weed by Redman's "How To Roll A Blunt" -- and pressured to drink booze by Snoop Dogg's "Gin and Juice" ... and he made it clear, he thinks Morant is being similarly impacted by today's tunes.

But, the "Holla Holla" rapper told us he thinks Morant needs to quit all of that ASAP ... telling us, "that ain't the way."

"Go play ball, man," he said. "The streets ain't about nothing, man. Go grind on 'em. Keep balling. That's it, man."

Morant has been investigated by police at least three times in the past calendar year -- most recently when he was seen on video flashing a gun at a strip club earlier this month.

Each time, Morant has dodged charges ... though he admitted in a sit-down interview with Jalen Rose this week he needs to start making better choices.

"In the future," he told Rose, "I will show everybody who Ja really is, what I'm about and change this narrative."
