Is cm punk really straight edge?

I think most people forget that CAFFEINE IS A DRUG.

He loves Pepsi, which is VERY HIGH IN CAFFEINE. He has a Pepsi logo tattooed on his left shoulder/upper arm.

Drug-free, no alcohol, no promiscuous sex. CM Punk fails in the Drug-free department.

His "Straight-edge" image, is nothing more than that. Just an image, a gimmick if you will.
