While Katy Perry has been smoking cigarettes most of her adult life, she says she's never smoked weed. When asked about smoking pot, she had this to say, "I can't do that stuff. I'd be like in the corner: 'Are you trying to kill me?!'" It seems like she has her smoking under control. Katy Perry has only been spotted having the occasional cigarette, so it doesn't seem like she's a heavy smoker. In fact, there was one time when she totally called out Rihanna for smoking too much weed. Here's what she said, "We all know how much pot Rihanna smokes!" If she's calling out other stars, let's hope she's not the ultimate hypocrite by partaking her self.
