*Yawn.*
The point of eliminating the "WOD" is not to encourage drug use. Stopping the "WOD" does not automatically mean legalization, actually. But you can stop making possession a mandatory prison-time serving criminal offense, and replace it with an exhorbitant fine, should you prefer. The "WOD" has given the government an excuse to trample on 4th Amendment rights, which I (as a NON-drug user) am concerned about.
Then you should harass your Congressman and Senators and get those particular laws removed, instead of throwing out the baby with the bath water.
Otherwise, if you don't like the idea of doing jail time for drug possession, the simple answer to that is to stay away from them. Problem solved.
