Green Cross Couriers, one of the largest companies transporting marijuana for dispensaries, has suspended operations after the state informed them they were not in compliance with the law. 

The company declined to be interviewed, but in an email obtained by CPR News, Green Cross said it’s suspending operations. The email alleges that the state will heap a big new expense on sellers and growers by shutting down marijuana transport companies. 

But the state's Marijuana Enforcement Division argues there’s no provision in state law specifically allowing couriers like Green Gross that store pot in a central warehouse, sometimes overnight. The division added that any dispensary using these services may be putting their license in jeopardy. 

The owner of a marijuana compliance company told CPR that courier services who follow strict reporting rules are still operating.

Editor's note: A previous version of this story incorrectly said that Green Cross Couriers was shut down by state regulators. The company chose to suspend operations after the state informed them they were not in compliance with the law.
