Paul McCartney says he's traded in his joints for wine or "a nice margarita" now that he's a grandfather. In an interview with The Daily Mirror, McCartney attributes his decision to a "parent thing," stating that "the last time I smoked was a long time ago."

The now-72-year-old grandfather/father is well-known for his indulging in marijuana in the past—he was famously busted for attempting to enter Japan with nearly a half a pound of marijuana in 1980.
