So are steriods but those get masked left and right. Performance enhancing drugs are

while recreational drugs are not

even though pot growing in Berkley, CA is allowed.
Weed can be masked just as easily. You can pull a bait & switch like the Whizzinator. Or you can drink any variety of goop found at your local headshop to cover the "scent" in your pee. In fact Ricky admitted to using it in the past when he first retired.And pot growing in Berkely (or anywhere in the US) is still not legal at the federal level.
Ricky knew the rules, the rules are there despite what any of you think about rec drugs, and Ricky violated the rules. Period. All other arguments fall aside.
And the CBA is up after this year (maybe next) so if the players feel soooo opressed they can have weed taken out of the list before they sign their next contract. And then you can have more Koren Robinson drops, or SODs running the wrong routes. Weed isn't performance enhancing, but it can sure as hell detract from it. If I'm paying somoene NFL money, I want them clear eyed and ready to rumble, not stoned and missing the weight room so they can watch Friday again.
And for the record, I'm an avowed pothead who feels it's criminal to keep medical marijuana illegal and it should be egalized in totality. Packed and taxed, just like cigs, but without as much lung cancer risks.
