A newspaper review shows that some of the country's biggest marijuana chains and board members of Missouri Medical Cannabis Trade Association are among groups that won licenses to grow, process or sell marijuana.

The St. Louis Post-Dispatch reviewed records and business registration reports related to the awarding of 338 licenses to grow, process and sell marijuana in Missouri.
