Use of performance enhancing drugs in Magic Hes there been a serious discussion on the use of performance enhancing drugs (such as Ritalin) during Magic tournaments or even as a part of the preparation process?

If yes, then where did the discussion ended up?

If not, then let me offer two points to start the discussion
Argument against allowing the use: Magic is a competition like any other, allowing these enhancers would ruin the integrity of the activity.
Argument for not taking a position on the matter: It would probably be quite difficult to implement any policy. That is, testing would prove too difficult and if the policy cannot be effectively enforced there is no point in having it.
