American Cannabis Society®
The American Cannabis Society® was founded on a simple but powerful idea: that cannabis education, advocacy, and community should be accessible to everyone. For years, ACS built a reputation as a trusted voice in the American cannabis movement — promoting responsible use, celebrating hemp culture, and connecting consumers with quality products they could trust.
As the cannabis landscape evolved across Wisconsin and the broader Midwest, so did the vision behind ACS. Recognizing the need for a stronger local presence and a retail partner that shared its values, the American Cannabis Society® became a brand of GreenRX™ — carried forward under new ownership that honors everything ACS stood for.
Today, the American Cannabis Society® legacy lives on at every GreenRX™ location. From our Madison HQ on Lien Road to our Sauk City and Sun Prairie storefronts, GreenRX™ proudly carries the ACS standard — curated THCA, CBD, and hemp products backed by education, transparency, and a genuine passion for the plant.
Whether you’re a long-time ACS member or discovering the brand for the first time, you’ll find the same spirit of community and quality at GreenRX™. Stop in, say hello, and experience the legacy.
