This has nothing to do with J-walking.  Cannabis Obstructionists turned to land use policy as their latest tool and created ‘protected land uses’ and buffer zones. The laws have proven unworkable for the Muni staff.  There is a role for buffer zones to restrict cannabis retail, particularly near schools.  But no need to get carried away.  Kids can't buy cannabis at regulated stores, only on the Black Market.  Muni law prevents a warehouse in an industrial neighborhood from being be used to grow cannabis near a child care facility or a church in the same industrial neighborhood. A warehouse is a warehouse is a warehouse. A kid wondering around an industrial area will encounter all sorts of dangers, the least of which is a grow light and a plant. The buffer zones are not about land use or protecting people, its obstructionism.  Having the Muni staff enforce obstructionists' policies is government waste and props up the Black Market. Time to rationalize the Muni's approach to cannabis.
