Tommy Chong Bieber's Talented BECAUSE He Smokes Out

EXCLUSIVE


Justin Bieber
 wasn't born with the talent to become an international superstar ... he inhaled it ... in the form of miraculous marijuana smoke -- so says legendary weed icon Tommy Chong.

The "Cheech & Chong" star was out in L.A. yesterday when we asked if he thought more highly of Bieber now that he knows the singer smokes pot -- and Tommy laughed, saying, "Of course!"

He said, "I knew [Bieber] was smoking before he knew it. Because of his music. Because of his dancing. The guy is a phenom ... It's not just his looks. It's his talent. And you don't get talent like that by drinking alcohol. The herb, man! The herb!"

Can't blame Bieber either -- Tommy says all the celebs are smoking ganja these days ... "Weed is mainstream as can be."
