What to Know
Laws & Program Details
Key facts about purchase limits, taxes, caregivers, and renewal — everything you need after you've been approved.
Daily Purchase Limits
Medical cardholders in Colorado can purchase up to 2 ounces of flower, 8 grams of concentrates, or 20,000mg of THC in edibles per day.
Tax Advantage
Medical purchases are only subject to 2.9% state sales tax plus any local taxes — significantly less than the recreational excise tax rate.
Caregiver Options
Colorado recognizes four types of registered caregivers for patients who need assistance:
- Cultivating caregiver
- Transporting caregiver
- Parent / legal guardian of a minor patient
- Advising caregiver
Patients Under 18
Minors can qualify for the program but require two physician certifications and a registered caregiver (typically a parent or legal guardian).
Card Renewal
Your card expires based on your condition type. To renew, you'll need a new provider certification and to submit a new online application before your current card expires.
