About Us

Green Thumb Industries is a medical & recreational cannabis cultivation and processing facility located in Rock Island, IL.

GTI Rock Island is the original cultivation facility for Green Thumb Industries. GTI now has cultivation facilities in 13 states, in addition to our corporate offices in Chicago, IL.

The Rock Island facility grows, processes, and ships products including vapes, flower, topicals, and tinctures for sale to marijuana dispensaries located in the state of Illinois. We are a 7-day a week operation that has grown from a staff of 3 employees in 2015, to over 200 employees currently in 2021.

GTI is the largest marijuana company in the United States when measured by the number of licenses awarded to operate. In addition to the cultivation facilities, GTI also has a retail division of marijuana dispensaries that operate under the name RISE.

Whether you enjoy cannabis for health, happiness, comfort, or another reason entirely, we believe in the right to have access, options, and most importantly, the safest products available.
