Short answer
Rules for patients under 18 in Kentucky are set by the Kentucky Office of Medical Cannabis and are stricter than the rules for adults. Where a minor can qualify, a parent or legal guardian is typically required to give consent and act as caregiver.
Key takeaways
- Check the Kentucky Office of Medical Cannabis’s current rules for minors before you book; requirements differ by state.
- A parent or legal guardian books and attends the evaluation with the minor.
- Some states require extra steps for minors, such as a second physician or a specialist.
- Ask the physician how Kentucky’s rules apply to your child’s condition.
Kentucky launched its medical marijuana program on January 1, 2025, making it one of the newest state programs in the country. If you want to know the minimum age to get a medical marijuana card in Kentucky, adults must be 18 years or older. Minors under 18 can also qualify — but with additional documentation and a required caregiver. Here is a complete guide to how the program works.
Kentucky’s Age Rules for a Medical Cannabis Registry Card
Under Senate Bill 47 (SB 47), signed into law in March 2023 and active since January 2025, Kentucky sets these age rules:
- 18 and older: Can apply independently as a qualified patient for a registry identification card
- Under 18: Can qualify as a minor patient, but must have a custodial parent or legal guardian registered as their caregiver
Kentucky also has a unique restriction: patients under 21 cannot purchase vaporizable products, even with a valid medical card. This applies to all patients in the 18–20 age range as well.

Qualifying Conditions in Kentucky
Kentucky’s minimum age to get a medical marijuana card in Kentucky rules apply equally across all approved conditions:
- Any type or form of cancer
- Chronic severe, intractable, or debilitating pain
- Epilepsy or any other intractable seizure disorder
- Multiple sclerosis, muscle spasms, or spasticity
- Chronic nausea or cyclical vomiting syndrome resistant to conventional treatment
- Post-traumatic stress disorder (PTSD)
The Kentucky Center for Cannabis Research can recommend additional conditions for approval over time.
What Minor Patients Need in Kentucky
If a patient is under 18, these are the specific requirements:
- The custodial parent or legal guardian must serve as the designated caregiver
- The caregiver must be at least 21 years old and a Kentucky resident
- Written consent from the custodial parent or guardian is required
- A second physician — separate from the certifying cannabis doctor — must document the qualifying diagnosis
- Minors cannot purchase any cannabis products themselves
- Minor patients cannot purchase vaporizable products regardless of condition
The two-doctor requirement for minor patients ensures an extra layer of medical oversight before treatment begins.
