Assembly Bill 1417 would require online review sites like Weedmaps (think Yelp, but for weed) to include state license numbers on all of their digital pot shop ads. The aim: to get rid of ads for illegal shops that currently dominate search results in cities like Los Angeles. Each violation would cost websites up to $2,500 per day.

“Our goal is to hold a level of accountability for these technology platforms that claim to just be a directory,” said Jerred Kiloh, president of the industry group United Cannabis Business Association, which is backing the bill, and owner of a Sherman Oaks dispensary.

“They’re not taking any responsibility that they are emboldening an illicit market,” he said.
