Johnny Depp says that he doesn't have a "physical need" for alcohol, but in an interview with Rolling Stone magazine he also admitted,

[Alcohol is] more my medication, my self-medication over the years just to calm the circus. Once the circus kicks in, the festivities in the brain, it can be ruthless.

I'm kind of socially inept. And [alcohol] was always a great crutch. Mingling at parties and stuff like that has always been not a nice experience for me. It's just not comfortable …. So I found I needed to drink in those situations. Just slam a couple down and go, "OK, I can muster up enough small talk to meander my way through this thing and get out the other side unscathed."

Possible Preaching Angles: (1) Alcohol; Addiction; Bondage, Spiritual—Like all of us, Johnny Depp is in spiritual bondage to something that he needs to make it through life. (2) Idol; Idolatry—Depp calls alcohol his "crutch." Isn't that just like having an idol? (3) Anxiety; Fear; Worry—Notice how even someone as famous and successful as Johnny Depp struggles with anxiety and fear in social situations.
