Breaking news: Kevin Smith and Seth Rogen smoke weed. OK, maybe it’s not so surprising, considering the “stoner” movies the two have been involved with in the past, but Smith sat down with MTV News to explain how funnyman Rogen recently turned him onto marijuana — and how it’s the best thing that has happened to him in five years.

Smith, who directed Rogen in 2008′s ‘Zack and Miri Make a Porno,’ claims Rogen is one of the most talented people he’s ever worked with.

“I got so much from him,” he said. “He re-energized me in a weird way. I became a stoner because of Seth Rogen.”

Smith was in awe of how Rogen could be a “functional stoner,” showing up to the movie set and be “brilliant” and “constantly writing [and] productive.”

The director had only tried marijuana a handful of times in the past and said it was his idea to share a joint with Rogen on the last day on the movie set.

“It was awesome,” Smith said about the experience. “We sat back, watched some footage and sat there smoking. And I loved who I was. I loved how the inhibition dropped away and I loved just being honest.”

And he hasn’t stopped since. The director claims he’s had the most productive years of his career thanks to Rogen — and weed.

“That dude gave me the greatest gift I’ve had in the last five years,” Smith said. “The moment I start smoking, I start working. … No one could ever say, ‘You fat, lazy piece of s**t stoner!”
