I think everyone knows smoking green isn't in any way a performance enhancer, and in reality it shouldn't be illegal or banned. That said it is and its a very small price to pay for a proffesional fighter to get paid doing what they love. I don't have a great deal of sympathy for Diaz or Silva and I don't think you can turn a bliond eye to it as it will open up a can of worms
I've sparred after a smoke in the past, and I got embarressed!
