Probably, but the more important question is why would anyone care? He's just a dude like anyone else. Talented and rich but just a dude.
He started getting uptight around the time Yoko showed up. [ame=http://www.youtube.com/watch?v=4JHrfq7h6CA]YouTube - Blackbird (recently discovered demo recording)[/ame]
For some reason, I thought he was anti-drugs now. So I googled it and couldn't find anything saying he was. I did find this though, and it gave me a good chuckle: Forensic experts say Paul McCartney was replaced in 1966? : Off-Topic Board
Paul said in a interview that he still enjoys a joint every now and then to relax him. Back in the 60's he was blazing that shit up every day!
I still thought he was doing it every day. There was actually a news thing from 2007 about Paul blazing it up before the Led Zeppelin reunion. One of the backstage workers apparently said, "Don’t worry, you’re a legend." I also remember reading this thing where Paul was walking on a street, and a group of teens called out to smoke weed with him. He said he was surprised that they still thought he was up to it. haha They're soo lucky. He definitely still does, though, and I wouldn't doubt he still does it often.
John would always bring Yoko everywhere and ask her everything so she basically broke up the Lennon/McCartney partnership cause now he could never talk to john 1 on 1. So he had to be paranoid of what Yoko thought cause it would easily influence John.
