this is all strictly my opinion, but i think the major sports leagues need to get together and create a universal drug policy, explaining which drugs are illegal, what the consequences will be for using them, and the testing procedures.

first of all, any drug that is illegal for the every day person should automatically be banned. testing positive for such a drug should result in a 1 year suspension.  drugs included in this group would include marijuana, crack, cocaine, etc.  a second failed test should result in a lifetime ban from all the major sports, as well as the termination of any contracts, and the loss of all money not already paid out from such a contract.

2nd, any drug that is clearly used with the intent of building muscle, strength or stamina should also be banned. sterroids should only be acceptable in the rehabilitation of a major injury, and should be required to have the player apply for an exemption to use the drug, on a limited basis, for the sole purpose of aiding in the rehab of the specific injury, and not for the overall bulking up of one's body.  there has been a system in place for bulking up which creates an even playing field for everyone, and its called weighlifting. those who turn to performance enhancers are simply too lazy to put in the work to do it the right way.

another problem is painkillers. alot of athletes take them, and with good reason. but where this becomes an issue is when a player is not only taking the prescribed amount, but also begging extra pills from teammates. anyone caught sharing their allotted amount of post-game vicodin, for example, gets a half season suspension for a 1st offense, full season for a 2nd offense, and a lifetime ban for a 3rd.

for too long athletes have been getting away with this kind of thing simply because of their ability to perform, as well as put fans in the seats, sell merchandise, and pay per view subscriptions on DirecTV and Dish Network.   if the average factory worker, receptionist, construction worker or nurse gets caught doing such a thing, they are subject to much more severe punishment, including termination of employment, legal action, and the difficulty in finding anyone willing to hire them.  i'm not saying they do it because they see athletes getting away with it, but i'm guessing there would be a dramatic decrease in such activity if the people in the public eye werent allowed to continually get away with it.
