Trees, a medical cannabis dispensary in California, already accepts payments in bitcoin alongside traditional payment methods such as cash, online bank transfer and credit cards. And now the San Francisco-based company is sending out drones to deliver cannabis.

After a short evaluation with a doctor, either online or at a clinic, patients can then choose from six different cannabis boxes, ranging in price from $59 to $149, all of which come with a certificate of authenticity. They must also state their preferred method of ingestion.

Currently, Trees only delivers to the San Francisco Bay area.
