ACK Natural is proud to maintain the highest levels of compliance and transparency in order to best serve the patients and consumers of Nantucket. At all times, ACK Natural’s products are subject to the Cannabis Control Commission’s (CCC) stringent and required testing and labeling requirements. However, the fact that Nantucket is separated from the mainland and cannabis remains illegal federally, Ack Natural is prohibited from having our products tested on mainland Massachusetts. The October 2021 recall is a result of insufficient testing of our products for one of the tests that is required by the CCC . We have purchased new equipment and updated our testing protocols.
As this process will result in updated procedures for our Island products and with customer safety and well-being as the number one priority for our company, ACK Natural will recall all products and offer exchanges or returns. If you purchased product from Ack Natural in 2021 you may return your unused product for a refund or replacement. Please email us to set up an appointment for the exchange and bring in your original packaging and unused product. For more information or to schedule a time to return the recalled product please email us at info@acknat.com
Thank you for your committed support!

Our Mission
Starting from the ground up, Ack Natural set out to create a welcoming open space for those both new to cannabis, as well as educated connoisseurs of cannabis flower.
Thirty feet below our state of the art dispensary, we have created the best growing rooms possible, complete with pharmaceutical grade PVC walls, a material heralded for its ability to resist mold and mildew. Using an integrated pest management system, we fly in predatory mites, and release them into the cultivation facility, as an alternative to pesticides. We also simulate sunrise and sunset by way of an advanced far-right red spectrum LED lighting system.
As a small, pristinely curated growing facility, we are able to give each plant the attention it requires to reach full maturation, resulting in the highest quality craft-grown cannabis that Nantucket desires.
