The Zack and Miri Make a Porno director-and-writer has smoked cannabis-laced cigarettes up to three times a day since Hollywood funnyman Seth Rogen introduced him to the illegal drug last year and thinks it had improved his scripts.
He quipped: "I know you're supposed to tell kids not to do drugs, but, kids, do it! Do weed! Don't do the other stuff, but weed is good
What you want to do is what I did, build a movie empire and, at age 38 smoke it all away."
The Jersey Girl director finds it hard to direct movies he has written and turns to his pal, comedy filmmaker Judd Apatow, and drugs to help him out.
He explained to the New York Post newspaper: "Judd Apatow is way better at being Kevin Smith now than Kevin Smith ever was. So Judd Apatow should do it for a while, and I should figure out something else, and weed has been f**king helpful with that.
Kevin, 39, is currently directing the upcoming police comedy A Couple of Dicks starring Bruce Willis and Tracy Morgan, which is due for release in February 2010.
