The provision states:

". . .none of the funds made available in this Act to the Department of Justice may be used…to prevent such States from implementing their own State laws that authorize the use, distribution, possession, or cultivation of medical marijuana," listing 32 states, as well as the District of Columbia, where the amendment would apply.

The amendment passed through the House of Representatives with bipartisan support in September. The bill will now go through the senate, and if finally approved, will effectively prevent the DEA from continuing to terrorize legal medical marijuana dispensaries and their patients.

It would also mean that dispensaries like Harborside Health Center, the most prominent medical marijuana dispensary in the U.S. since 2007, and the people who run them wouldn't have to worry about being arrested for providing medical marijuana to the thousands of people who can benefit from the plant's powerful healing qualities.

Several years ago, the Department of Justice issued what has become known as the "Ogden memo" — a missive from Deputy Attorney General David Ogden telling federal law enforcers that they should not focus federal resources "on individuals whose actions are in clear and unambiguous compliance with existing state laws providing for the medical use of marijuana," Even still, local police departments and even DEA agents have been known to harass medical marijuana patients and dispensary owners.
