A medical marijuana delivery app in the Bay Area is offering free weed to new customers.

Eaze, which describes itself as a technology service, says its fleet of drivers can bring medical cannabis to users in 34 Northern California cities within about 15 minutes. Through Feb. 14, new users of the app will get an eighth of an ounce of marijuana for free, no purchase necessary, with the promo code EAZE4ALL.

Founder and CEO Keith McCarty has described the app as Uber for weed. In the app's first 24 hours, McCarty said they made "hundreds" of deliveries.

Users of the app must verify that they have a current doctor's recommendation for medical marijuana. From there, they can scroll through a menu of marijuana products made available by the dispensaries Eaze partners with. In addition to marijuana buds, users can find cannabis products including concentrates and edibles.

The company prides itself on its algorithm for quick delivery. After seeing the need for convenient and consistent access for medical marijuana, McCarty said he decided to partner with dispensaries.

"We're able to create that consistent experience for patients and turn this fragmented marketplace into a consistent use experience for patients," he said.
