Funny, according to the MLB Players Association, they are tested for THC http://mlbplayers.mlb.com/pa/pdf/jda.pdf Maybe MiLB baseball players don't have a vote, but they are protected and legislated under the same collective bargaining agreement as the MLB players and choose to enter into the agreement contractually under their own free will. I don't care if pot is legal or not, if a person enters a contractual obligation, it's up to them to hold up their responsibility. You'll notice several legal and prescriptive substances in the list of drugs of abuse such as synthetic THC and Codeine. Whether pot should be tested for, it was the players association that voted to approve the contract under drug of abuse, not PED. It's a safety and addiction issue contractually. Employers should have the right to protect themselves, their properties, and their customers, as well as the players should have the right to collectively bargain player contracts that are in the best interest of the players association. For all we know, it was the players association that bargained this issue into the contract. I think if the players wanted alcohol to be a tested substance of abuse, it should be included as well. On the freedoms and liberties issue, I think pot should be legal. It's so prevalent and socially accepted that it's unreasonable to treat it differently than alcohol.
