Medical marijuana storefronts would be banned within 600 feet of a school in legislation intended to shield children from drugs.
The bill, AB 2650, was approved Thursday by the state Assembly.
Assemblywoman Joan Buchanan says the bill seeks to protect children while allowing the legal operation of medical dispensaries.
Many cities already have enacted their own ordinances regulating where dispensaries can locate. They would be exempt from the proposed law.
The Democrat from Alamo says her bill would not apply to individual caregivers.
The bill was passed by a 45-12 vote. It now goes to the Senate.
