In the recent election people voted on a reeferendum and now marijuana is legal for recreational use in Colorado and Washington state. theres been talk on ESPN that the players who live in those states should be allowed to smoke if they choose to. I know marijuana is on the banned substance list for baseball as well as other sports but do you think they will alter it? its still illegal by federal law so i would say no way. besides, from what i saw in the interviews from older players they said that pot smoking has been and still is a big problem in sports. Most notably that they all get tested for pot at the same time every year and only once a year so its easy to get around. So i guess they're going to do it regardless of what the rules say (much like the rest of america).
I can see it happening in football, with the dangers of perscription painkillers becoming clearer and clearer football players are more hesitant to use them and marijuana is a safe and effective painkiller and could be a good alternative to addictive and organ destroying pills.
