Don’t expect that dank to be delivered via drone anytime soon.

The California Bureau of Cannabis Control has officially declared the cannabis deliveries cannot be made by autonomous vehicles – including UAVs and self-driving cars.

"Transportation may not be done by aircraft, watercraft, rail, drones, human-powered vehicles, or unmanned vehicles," reads the bureau's updated business licensing regulations.

"Deliveries may be made only in person by enclosed motor vehicle. Cannabis goods may not be visible to the public during deliveries. Cannabis goods may not be left in an unattended motor vehicle unless the vehicle has an active alarm system. Vehicles used for delivery must have a dedicated, active GPS device that enables the dispensary to identify the geographic location of the vehicle during delivery."

This announcement will no doubt be unwelcome news for proposed autonomous cannabis delivery start-ups in California like MDelivers, Eaze, Trees Delivery.
