It's not clear whether actor Seth Rogen is smoking marijuana, or something else, in this appearance at MTV's movie awards, which were televised live. But there are three thing you can say for sure. One, the camera pulls back, as though the network wants to obscure the smoking. Two, Rogen just earned some serious publicity for his upcoming stoner film, Pineapple Express, part of a resurgence for the genre of pot movies, which Hollywood considers cheap to produce but highly profitable. And, third, someone is going to get seriously scolded by various media watchdog groups for promoting marijuana use on national television, whether the weed is real or not.
