I say leave the number-choosing to the states.

Regulate medical marijuana like any other non-scheduled drug and leave cultural decisions concerning recreational use to the states, where it belongs. Use federal funding stipulations as leverage when needed.

Pick a number and it is still arbitrary, doesn't matter who does it ;)

I didn't mean to imply that it was any less arbitrary (the arbitrariness of the numbers is disputed in other threads), only that I view the feds setting that number as overstepping.
