What we can do:
Directly: Not much, as this is in the hands of the courts.
Long term: Help re-establish an appropriate balance of power between the state and federal governments by:
- Studying the US Constitution and it's history, and deciding for yourself what is an appropriate separation of powers
- Encouraging state and federal officials to implement that balance of power. In this case, allow states to regulate the use of marijuana within their borders by supporting Congressional acts such as the "Truth in Trials Act" and the "State's Right to Medical Marijuana Act".
