MassRoots announced the news yesterday:
Over the past few weeks, cannabis consumers around the world united behind a common message: cannabis apps should be made available in the states that have voted to legalize its medicinal or adult use. Today, we’re excited to announce the App Store has changed its enforcement guidelines to permit cannabis social apps in the 23 states that have legalized medicinal cannabis. MassRoots is now available in the App Store!
MassRoots thanked the National Cannabis Industry Association, ArcView Group, Whaxy, and The Cannabist for their support and the tens of thousands of users and advocates that signed their petition to Apple.
You can download MassRoots from the App Store for free.
