How much cannabis can I possess in Iowa with an MMJ Card?

Iowa has no limit to the number of medical cannabis products a registered patient can possess, but purchases are limited to a total of 4.5 grams of THC every 90 days. However, there are exceptions for patients certified for terminal illness and patients already active in the program.

Patients with a terminal illness may be approved by their certifying provider for over 4.5g THC at the time of their approval.

Current patients who are already cardholders must be approved for a THC increase by their certifying provider and submit the signed 4.5g THC Waiver to the Iowa Medical Cannabis Program.
