Is anyone else dealing with a friend or family member with a cocaine addiction?

I have (or had) a friend who recently has been using cocaine. I’ve definitely seen a change in his personality. He is ADD, a bit narcissistic and constantly craves to be the center of attention. Now those traits have gotten a lot worse to the point where I can’t stand hanging out with him anymore. I miss my friend the way he used to be… can anyone relate to this?
