SAN DIEGO (AP) - Medical marijuana dispensaries that are being run out of San Diego are fighting back.

The San Diego Union-Tribune says an association of medical marijuana collectives will unveil a proposed ballot measure this week that would regulate the clinics and allow the city to tax them.

Proponents would need to collect about 62,0000 signatures from registered voters to qualify the measure for next November's ballot.

Medical marijuana collectives flourished after Californians passed a law in 1996 permitting possession and use of marijuana for some medical reasons but they remain illegal under federal law and a recent crackdown has forced many to close.

San Diego's city attorney also has sued collectives for violating local zoning laws.
