Tom Ammiano, a member of the San Francisco Board of Supervisors, has proposed an ordinance calling on police to scale back almost all law enforcement pertaining to marijuana, focusing only on crimes involving minors, driving under the influence, or public sales of the drug, the San Francisco Chronicle reported Sept. 12.

Ammiano's proposal, which would not be binding on police, calls for making most marijuana crimes the lowest enforcement priority for San Francisco police. The lawmaker noted that city residents passed a measure back in 1978 calling for an end to marijuana arrests and prosecution -- dubbed Proposition M -- and that the current legislation reinforces that sentiment.

The measure would see the city refuse federal funds for investigating or prosecuting marijuana offenses and establish an 11-member board to review police activities related to the drug.

The board is expected to hold a hearing on the proposal in the coming weeks.
