Well, no. Let's not confuse kayfabe with reality. As a WWE performer, Punk would be entitled to the same number of chances as everyone else. True, failing the test would blow his on-air character out of the water, given that his whole persona revolves around being straight edge. The program with Chris Jericho that was interrupted points out that Punk's entire act is dependent on his being "clean." Plainly, that program isn't going to end with Punk being proven a hopeless alcoholic, now is it?
In real life, Phil Brooks could have already flunked drug tests, for all we know. I believe there are just a few performers who either have their test results buried.....or aren't tested at all because their presence is so vital that the company can't afford to lose them. Obviously, John Cena is one. They simply can't chance losing him to something as "trivial" as a failed drug test. (At the same time, he's probably smart enough to not do drugs, knowing that a failed test could toss him off the gravy train).
Then, how about Mark Calaway? Can you imagine WWE testing him? Can you imagine them firing him if he failed three times? I sure can't.
You might counter this by tossing Randy Orton at me. Certainly, it seems he's one of the performers the company can't spare. Yet, don't you have the notion in recent months that the company might be looking for a way to get rid of Randy? Or, at least to make him fall in line by suspending him down to his last warning? I had believed him to be unexpendable; now, I'm not so sure.
Amidst all these questions, there's C.M. Punk. I think he's almost in the class of Cena and Undertaker as guys WWE can't afford to lose...... and if the behavior of their employees is something WWE can't control, they can at least cover up failed drug tests.
It may have already happened with Punk......who really knows? No, I'm not saying I have inside knowledge that he's flunked a test; I'm saying we would probably never know if he did.
To paraphrase the book "Animal Farm": All wrestlers are equal......but some wrestlers are more equal than others.
