City attorney Mike Feuer says that more than 500 pot shops have been closed down in Los Angeles in the last two years. This after Proposition D was passed 2 years ago. It imposed stricter standards on medical marijuana dispensaries. Among the new requirements: they can’t be open after 8 PM, or be within 1000 feet of a school, or have any kind of lighting like a neon sign that’s on during non-business hours. Dispensaries that do not adhere to these standards will be targeted and shut down. What’s unclear still is how many pot shops are open in the city.
