A bipartisan coalition of lawmakers has reintroduced legislation that aims to protect state-authorized medical marijuana patients and their providers from federal prosecution.
...Seventeen states -- Alaska, Arizona, California, Colorado, Connecticut, Delaware, Hawaii, Maine, Michigan, Montana, New Jersey, New Mexico, Nevada, Oregon, Rhode Island, Vermont and Washington -- have enacted laws protecting medical marijuana patients and their providers from state prosecution. Yet in all of these states, patients and providers still face the risk of federal sanction -- even if their activities are fully compliant with state law.
Passage of the Truth in Trials Act would codify legal protections for defendants caught between state and federal laws, ensuring that they can cite state law as a legal defense in federal trials.
HR 6134 is now before the House Committee on the Judiciary.
