Seth Rogen was "genuinely shocked" when he discovered marijuana was illegal in California.
The actor was arrested for drug use when he first moved to Los Angeles because he had forgotten about the different legislation.
Recalling the moment to Rolling Stone magazine he said: "I was genuinely shocked at how illegal it was here. I actually got arrested when I first moved to LA - I was smoking a joint at the beach, like I did my entire childhood, and all of a sudden, it was, like, whoop whoop whoop! Handcuffed in the back of a police car."
Despite the arrest he doesn't believe he has a criminal record.
Seth has meanwhile had a special preview of Kanye West's forthcoming record, after the rapper invited him into his limo van and forced him to give opinions on each and every track.
"There's no lyrics, only beats. So he raps the whole album, and after each song, he stops it, like, 'So what do you think?' We were in the van for two hours!"
