Los Angeles City Attorney Mike Feuer has sued Nestdrop, smartphone app for medical marijuana delivery.
The app allows customers to order medical marijuana to be delivered to their door step. The app also facilitates alcohol delivery.
The lawsuit demands shutting of the application in Los Angeles and stopping the app maker from re-establishing any such business in future.
It is the first time authorities have targeted medical marijuana apps that are prohibited under the, Proposition D, which outlawed the operation of medical marijuana businesses in the city.
Authorities in Los Angeles have struggled to limit the number of medical marijuana shops for over a decade in Los Angeles.
According to reports similar apps and delivery services might have to go through criminal prosecution.
Mike Feuer said: "My office has moved aggressively to shut down unlawful medical marijuana businesses, already closing half the dispensaries operating in Los Angeles.
"And today we’re taking action on a new front, tackling medical marijuana delivery."
