NASCAR, JEREMY MAYFIELD, DRUGS, UNIONS??

I am sitting here wolfing some chow just trying to figure out what's in the minds of NASCAR with their drug policy & banned substances. I, by no means am condoning the actions of Jeremy Mayfield. I do agree with NASCAR's action in dealing with the offense. But where does NASCAR get off with having a total drug restriction. (Oh they clarified that with 'only medication prescribed by a physician') That makes it OK. I mean, aspirin is a drug; also many other legal pain meds and symptom relievers, I guess they are all banned. NASCAR racing is a dangerous sport. There is no dispute with that. Many over the counter drugs can affect ones ability to function in one way or the other. They must implement a policy similar to US Professional Sports Organizations such as NBA, MLB, NHL, NFL, & so many others, TNTC. Each one has a list of banned substances with penalties assigned to them. Is NASCAR exempt?? They are more concerned about pit "SPEED"!!! Ooops; did I just say SPEED??? I guess if you have a headache one day; you just suffer! O just suffer NASCAR's wrath as they see fit.
I’m not so sure about a drivers' union? That’s a subject for another day. http://bit.ly/PbwqH
