And just last week, Holder announced that the federal government strongly opposes Prop 19 and will aggressively enforce federal marijuana prohibition in California, regardless of Prop 19's outcome.

In a free society, the presumption must be that people can smoke, snort, eat or inject whatever they wish, so long as they do not harm others. The burden of proof should rest on those who would ban marijuana, not those who want it legal. That burden has never been met.

By adopting Prop 19, California can restore a presumption of liberty. That is reason enough.
