Tell that to the safe injection site in Vancouver where they reduce the suffering and incidences of disease.
The war on drugs is a lost cause, harm reduction is the only way forward both to save money and to enact changes of behavior.

As for the gay "marriage" thing, DOMA effectively does what Ron Paul cites should be done. It lets the states decide how they wish to define marriage. It ALSO ensures that Massachusetts doesn't get to define Florida's marriage law or that Connecticut doesn't get to define Michigan's law.
The reason Obama wants DOMA gone is that he can effectively endorse gay "marriage" without actually doing so in word. That happens if the other 45 states have to recognize the gay "marriages" from the states that allow it.
