Seth Rogen gets Conan O’Brien to smoke a joint on air during his final week of shows

Earlier this year, Seth Rogen unveiled his new weed line House Plant that he’s been working on for a decade. And when Conan O’Brien asked Rogen during their interview what advice he would have for O’Brien to relax, Rogen suggested taking up weed. He then took it a step further and presented him with one of his joints, and got O’Brien to toke up on the air. The last time we saw O’Brien get high on the air, he was indulging in weed brownies with the late Larry King.
