If there's one person who defies all pot-related stereotypes, it's Paul McCartney, the most successful songwriter in human history.
Legend has it that Bob Dylan turned the Beatles on to pot in 1964 and Paul was by his own account a regular user through 2012. McCartney told Rolling Stone that as a 69-year-old father of a young *****, it was time to call it quits. "I did a lot, and it was enough," he said, adding that cannabis was "such good stuff."
During his 48-year run as a pot smoker, McCartney was a hugely productive member of The Beatles and Wings and enjoyed an incredible solo career. He developed a reputation as a good guy, a dedicated husband, and a responsible business partner. He had repeated run-ins with the law regarding pot, even being deported from Japan in 1980 for carrying the stuff.
Would he have written such songs as "Yesterday," "Hey, Jude," "Let It Be," and "Maybe I'm Amazed" and recorded dozens of albums if he hadn't smoked pot on a regular basis? Perhaps, but the point is that he did smoke pot while creating one of the richest musical legacies of all time.
That's certainly not an argument to use marijuana, but it is a fairly definitive rebuttal to claims that there is no "responsible way to recreationally use marijuana."
