Am I able to use my medical card from another state?

No, but you will be able to purchase recreational cannabis provided you are +21 and have valid ID. Illinois does not allow anyone without an Illinois medical cannabis card (or who is a caregiver for an Illinois medical cannabis patient) to purchase medical cannabis.

Eligible conditions for medical cannabis can vary by state, but if you have recently moved to Illinois, your condition may qualify you for an Illinois medical cannabis card.

Note: You must be able to demonstrate that you are an Illinois resident to qualify for an Illinois medical cannabis card.
