The players do it anyhow in season knowing they only get tested once for the year. Nothing would change. Maybe Trump should just legalize marijuana at the federal level. The protesters might back off him if that was the case. Its legal in Canada, it's legal in many states. There haven't been any negative ramifications that I'm aware of. If they make it legal and tax the crap out of it then it would be a big money maker plus make the liberal crowd happy
