While I completely endorse full legalization, we are not there yet. If you want to see what happens when you push the edge too hard for the conservatives to stomach, just take a peak at what's happening in Montana and Michigan right now.

Montana = Medical Marijuana Repealed
Michigan = Heavy police [and DEA!] activity.

We have made Medical Marijuana part of our supreme law, and should treat it as such.
There will be a day when full legalization happens, but it has not happened yet.
