It was a busy week for actor Zac Efron. Last Sunday, he was attacked by vagrants in Los Angeles. Then, on Friday, Efron was seen puffing on a portable vaporizer in a car in Los Feliz.
It's unclear whether Efron is inhaling cannabis or nicoctine. Either way, it's apropos. In his next movie, Neighbors, he co-stars with Top CelebStoner Seth Rogen. It opens May 9.
