Drugs and Entertainers

I don't know what is getting into all of Hollywood, but it is craziness. Don't they have the same rules that the general population do as far as work requirements? I mean we are all getting paid squat for our jobs and here they are making millions and we make pennies, yet we are drug tested, back ground checked and thoroughly violated, and here they are high on life and making millions. Doesn't seem right if you ask me, they should have to be screened just like anyone else, and if they are tested positive, then they lose their jobs as well. Make it fair for the world, don't punish the innocent. Just my opinion, what's yours?
