City Council members in Berkeley, Calif., were voting Monday on an ordinance that would require medical marijuana dispensaries to fork over a portion of their inventory to low-income and homeless residents.

The requirement is buried in a dense 20-page ordinance to amend the Berkeley Municipal Code. A new chapter in the code includes the section “Medical Cannabis for Low-Income Members,” requiring the town’s four medical marijuana dispensaries to provide “at least 2 percent (by weight) of the annual amount of Medical Cannabis” they sell to “very low-income Members who are Berkeley residents,” at no cost.
