San Francisco’s legal cannabis market is poised to get a boost as City Attorney David Chiu takes action against the owners of warehouses implicated in illegal marijuana cultivation. In a lawsuit filed today, Chiu targets two Bayview warehouses where over 5,800 cannabis plants were seized. The city’s legal action is aimed at P.A.A. Property, LLC and its manager and president, David Chi-Yu Lai, accused of supporting unlicensed cannabis production that skirts taxes and health regulations, which legit businesses comply with.
