The Green Door was Ann Arbor's premiere medical marijuana dispensary. We had to shut the dispensaries doors but we have recently reopened as a Cannabis Certification Center in May of 2018. We are here to help you with all of your certification needs. We also have CBD products, glass, and accessories available in the center for patients, as well as references to wonderful dispensaries you can visit.

A Doctor is on site multiple days a week for your convenience.

Mondays 5:30pm - 8:00pm
Tuesdays 2:30pm - 4:30pm
Fridays 2:00pm - 4:00pm
Saturdays by appointment

Marijuana (also known as cannabis or THC) is emerging as an alternative treatment for a variety of medical and psychological conditions from cancer and arthritis to depression and insomnia. While the use of marijuana as medicine is still a subject of debate, a number of benefits of marijuana could make it a safer and better option for patients seeking alternative or supplemental therapies for their ailments.
